Back To School Lessons On Air Conditioning

Good Deals Heating and Cooling air conditioning

While students are out on holiday, schools are fixing up their classrooms and hallways. It is the summertime, which means it’s hot in many regions of the country, especially in southern areas like Florida, Arizona, and California. When students come back in late August/early September, the summer heat is still around and affects the students. Research has shown that hot rooms make it difficult for students to study and pay attention to the teacher. Air conditioning can give plenty of relief, but only if the schools had adequate, fully functioning air conditioning.

Schools without adequate air conditioning higher temperatures by a few degrees, which can have adverse effects on students. For every 1-degree Fahrenheit increase, there is a 1% decrease in learning. One research study measured students PSAT scores. One group took the test in a classroom an averaged temperature and one group in a classroom two degrees higher. The average scores were higher from the students who had a cooler classroom. Other studies have focused on students taking general exams in certain conditions. In warm rooms, the chance of failing a test rises to 12%. Why? A person working in high temperatures loses concentration as they focus more on finding a way to cool down.

The problem with air conditioning is more prevalent in schools in low-income areas that are overpopulated. In these schools, classroom temperatures run one to three degrees hotter than in higher income schools with proper air conditioning. There is a racial factor because these low-income schools feature a higher percentage of minority students, namely, Hispanics and Blacks. White students were from higher income schools. Many of the schools are public, and the cost of installing a new air conditioning system is not within the school administration budget.

Air conditioning in schools is becoming more essential because of climate change. It is up to government officials to counter the rising temperature and focus on more Eco-friendly ways to use energy that allows air conditioning to work for all. Global increased temperatures mean that all students, regardless of where they are, will be affected. Improving school infrastructure should be an immediate “yes,” but local governments with numerous issues have yet to commit.

Anyone around hot temperatures can easily suffer from dehydration, heat stroke, and nausea. In the sweltering southern locations the heat lasts longer than in the north, and air conditioning is more critical in schools. Having the classrooms maintain a comfortable temperature improves students’ energy levels and increases the students’ ability to maintain focus.

Air Conditioning and Your Summer Vacation

Good Deals Heating and Cooling air conditioning

Summer is here and this is the time people start traveling on vacation. Holidays are exciting, but a few preparations around the house will allow peace of mind while relaxing. Items to include on the list are: arrange to have the mail held or picked up, contact a pet sitter, place lights on timers, and compile a packing list for the trip. When making this list, don’t forget about the HVAC system. Preparing the air conditioning system for the house to be empty for an extended period will save money and avoid problems while you’re away.

Turn Up the Thermostat

Summer heat can have a significant effect on wood flooring, doors, and cabinets. Don’t make the mistake of turning the AC system off in a bid to try and save energy. The summer heat and humidity can cause hardwood floors to expand and buckle, and wood doors to expand and not close properly. Save yourself the cost of repairs by turning up the thermostat setting to between 80-85 degrees Fahrenheit. This temperature range will not damage plants or fabrics, and by keeping the HVAC running, the humidity will be controlled. If there is a programmable thermostat, program it to have the house return to a comfortable temperature a hours before returning.

Consider Surge Protection

While on vacation, losing power is a possibility. In case there is a power surge or outage in your area, and no one is around, the HVAC system might get damaged. Install a surge protector for the system to avoid that problem.

Schedule General Maintenance

Have a technician check the HVAC system before the summer season. A service technician will check the following: refrigerant levels, coils, air filters, electronic connections, and the system is producing the correct temperature across the evaporator coil. Knowing the HVAC is in optimal working condition while on vacation will lessen any worries.

Air Filter Routine Maintenance

Clean air filters before leaving. Clogged air filters cause the HVAC unit to overwork. Clean air filters prevent the system from malfunctioning while no one is around.

Reduce the Load

Computers and other electronics produce heat when they are running. Turn off or disconnect these items while away to reduce heat generated within the house. The HVAC system will turn on less frequently.

When anyone goes on vacation, they want to have some time away from home to relax. Follow these simple tips for, and you’ll have a worry-free vacation.

Is a Ductless HVAC System Right For Your Home?

Good Deals Heating and Cooling ductless HVAC systemHVAC systems are crucial to keeping the climate right in your home. There isn’t a one size fits all solution to choosing an HVAC system. You need to select the option that is right for your home. One of the options out there is the ductless HVAC system. A ductless system provides excellent comfort at a stable and consistent temperature.

Is Your Home Already Built?

Ductless systems are great for homes that are already built because they require only a minimal amount of alteration. A small hole needs to be drilled into the wall to feed hose from the compressor to the unit. The size of this hole is only a fraction of the size of a standard HVAC hole. You will also need to mount the unit, but that is simple.

Looking For Energy Efficiency?

HVAC systems can be a significant consumer of your power system, costing you a lot of money. A ductless HVAC system, on the other hand, is a very energy efficient solution. Your HVAC duct is taking around 25% of your energy from your home. Compressor startup on the hand will still consume a good portion of your energy.

An Energy Star rated ductless HVAC system can save you even more money. Energy efficiency isn’t only about the money that you are saving, but also about protecting the climate.

Flexible Option

With a ductless HVAC unit, you have plenty of options. You don’t have to worry about where in the room, or home, you put the unit. It doesn’t require a connection to a central unit.
Each room can also be set to different air temperature. People will be able to get the desired level of comfort in each room.

Need A Quick Installation?

Don’t want a significant disturbance around your home during the installation process? Putting in a ductless HVAC system is quick and easy. A qualified individual can have the work done in a day or two. On the other hand, a traditional duct system can take weeks to install, during which time you won’t be able to use rooms.

Which HVAC duct system you get will be up to you. Ductless HVAC systems have a lot of benefits. Make sure that you do your research and read into the benefits of ducted HVAC systems. Being well-versed makes you able to make an informed decision. An essential part of a substantial investment.

What Are The Different Types Of HVAC Air Filters

Good Deals Heating and Cooling HVAC air filtersOne of the most critical parts of your HVAC system is the air filter. The air filter is responsible for keeping the air that enters your home clean of contaminants. Bad air quality can also clog your HVAC system. Understanding the different types of HVAC air filters will help you to determine which is best for your home.

Fiberglass or Synthetic Filters

If you are looking to spend the least amount of money, what you are looking for are fiberglass and synthetic filters. These are both affordable and disposable. Particles 50 microns or larger are filtered out up to 80% by these filters. Particles between the size of 3 and 10 microns are filtered at 25%. BY using these filters, you can filter out dust and dirt but not all harmful contaminants from your home or office.

Polyester Based Filters

Filters made from polyester are one of the highest quality that you can get. Particles at or above 5 microns are filtered between 80 and 95%. You will get extreme filtration but at approximately four times the cost of the fiberglass or synthetic filters mentioned above.

Electrostatic Filters

The fibers in these filters are self-charged to create electrostatic attraction. Both standard versions of electrostatic filters and washable versions are available. Between the two there will be a MERV (Minimum Efficiency Reporting Value) rating of 4 to 10 depending on the specific filter. Washable filters will last longer than disposable filters.

Pleated Filters

For those that desire to catch the smallest particles floating around, the pleated filter is the right option. They can catch particulates that are down to .3 microns in size. That includes most contaminants and allergens. At the same time that pleated air filters give you the best filtration, they allow decent airflow.

HEPA Air Filters

Out of all of the HVAC air filters, a HEPA filter is the most effective. It will capture up to 99% of particles that are .3 microns or above. HEPA filters provide fantastic filtration at the cost of some airflow. Your system will have to work slightly harder when using these filters, costing more money.

Now you know the major types of HVAC air filters out there you can make an informed decision about which one is best for your system. Are you okay with minimum filtration with the benefit of cost saving or do you need something more robust? If you already have an HVAC system in place, make sure that the filter you decide to use is compatible with your system.

Is My AC Low on Freon?

Good Deals Heating and Cooling air conditioningAir conditioners are fantastic at keeping a home cool. Unlike fans, air conditioning adjusts to maintain a home at a precise temperature. Throughout the summer, people trust that their AC will be there to keep their house cool. That is, as long as the air conditioner has the proper level of freon. How do can one tell when an air conditioner is running low on freon? We are going to examine some of the signs today.

AC Isn’t Keeping The Room/House Cold

There are two main reasons that an air conditioner might not be keeping a home or room cold. One reason is that the unit is the wrong size for the overall area to be cooled. But, if the AC unit usually works fine for cooling the area, but now it is not then it probably lacks freon. Then It is time to call a technician to check the freon levels. If the freon levels are fine, then the technician can check the rest of the unit for problems.

When the temperature in a room doesn’t feel right, compare the temperature on which the air conditioner is set with the actual room temperature. This check is an excellent way to verify if the AC unit is keeping the area regulated.

Ice Is Building Up On the AC Unit

A specific part of the AC unit, called the evaporator coil, handles the chilling of air. That means this is the only part of the unit that could build up condensation during normal operation. If ice is noticed building up around the air conditioner unit, it is running low on freon. Replace the freon before continuing to run the system. Water leaking into the wrong part of the AC unit can cause a short circuit.

Electric Bills Are Going Up

When an air conditioner unit is low on freon, it has to work harder to keep the air cold. That means that it requires additional electricity. There can be a lot of reasons that an electric bill might go up, but when troubleshooting the problem, place check freon level to the list.

While an air conditioner is capable of running without the freon topped off, it should be filled as soon as possible. Many people start to notice the lack of freon when it starts to hurt their wallets. At the same time, running the risk of a unit breaking down when the freon is low will cost more in the long run because a service call to have the freon level checked is much less expensive than replacing a unit.

What Temperature Should I Set My Air Conditioning While On Vacation?

Good Deals Heating and Cooling air conditioningThe summer vacation is the ideal time to give residential air conditioning units a break. In fact, it is pointless and expensive to have the central air conditioner running if no one is present at the house. The one exception is if the pets are left at home, in this case, the air conditioner must not be completely turned off. Instead, the air conditioning unit should be but can be set at a higher temperature than usual.

By setting the thermostat to a warmer temperature, you can cut your electricity bill. Raising the temperature by one degree, cuts about 3% off the electricity bill. However, just because a higher setting will cut a monthly utility bill, a homeowner should not increase the temperature too much. Remember air conditioning does not only regulate the temperature in your home it also controls the humidity level. When the atmosphere within the home becomes exceptionally humid and hot, microorganisms and mildew can thrive making the indoor air unhealthy.

When the temperature is too high within the house, appliances like refrigerators can start to emit moisture and run harder to stay cool. Also when you return from vacation, cooling down the home to a comfortable temperature, the air conditioning unit will have to work hard thus eliminating some of the savings.

Therefore, the temperature should be raised about 4 degrees above the comfortable temperature the homeowners generally use. For instance, if the normal temperature is 72, increase it to about 76 before everyone leaves the house. With such a setting, the house will maintain an adequate temperature (which is not too hot) and still save some electricity. However, if there are pets in the house and the family is leaving for several days adequate measures must be taken. That means the pets should be sent to a care center or ask a friend or a relative to look them after. Even when the pets are left at the house for about a few days, the best practice is to ask the veterinarian about the best temperature setting according to the type and size of the animal.

Why is My Air Conditioning Freezing Up?

Good Deals Heating and Cooking air conditioning repairFreezing up or icing up of air conditioners is a frequently encountered problem. Irrespective of the fact, whether the unit is a window AC or central AC, the reasons and the solutions are similar.  One cannot ignore freezing up in an air conditioner. It gives rise to two problems: inefficient cooling and potential damage if not corrected.  The key is to know when to call for air conditioning repair.

To understand why an air conditioner is freezing up a thermodynamics principal needs to be understood. The Joule-Thomson effect states, that when a gas expands, its pressure as well as temperature decreases. This result happens when all the other parameters are kept constant. Similarly, when a gas is compressed, the temperature increases. In other words, molecules of the air feel hot when they are moving rapidly and when they move slowly, the air feels cold.

On this basis, the evaporator coil in an AC expands the refrigerant. This expansion causes the coil to cool. The cold coil then mixes with the air at room temperature, and the coolant absorbs the heat. The now heated refrigerant is then thrown out of the house by compressing it, which heats it up and transfers it outside. The cycle gets repeated many times, and the room gets cold. When there is a problem, the air conditioner’s evaporator coil gets much colder than it should, thus freezing up the AC. This freezing up happens due to several reasons:

No Enough Airflow Across the Evaporator Coil: ACs are meant to bring down the temperature by drawing away the heat. If the AC is not blowing the internal air correctly over the coil, the exchange of heat does not take place. Over time, the coil temperature will drop, and the AC freezes up.

Low Refrigerant: When the amount of refrigerant (freon) in the system is low, it still expands to the same amount. As stated above when gas expands, the temperature drops. As the temperature of the coil drops below the freezing point, the moisture in the air freezes when it contacts the coil, thus icing it up.

Mechanical Problems: If an air conditioning repair is required then the pressure change in the system leads to freezing up. The problem may include an obstacle in the refrigerant, a non-working blower, or a blocked filter.

High Outside Temperatures: When the outside air temperature is extremely high, and the AC is continuously running, the system pressure inside the unit will drop and cause freezing up.

For an air conditioner freezing up on a consistent basis, call for air conditioning repair to get to the root of the problem. For assistance in the Philadelphia area, contact Good Deals Heating and Cooling at 215-947-1166.

Improve Energy Efficiency With The Right Thermostat

Good Deals Heating and Cooling energy efficiencySaving electricity and improving the energy efficiency is a lifelong battle that can be hard to conquer. Many gadgets on the market can meet your needs and reduce the burden on the electrical output. One such electronic device is a thermostat which regulates the heating and cooling in the home. If you have the right type of thermostat installed in your home, you can save enormously on your electric bill.
The different kinds of thermostat that are available are:

Programmable

A programmable thermostat is a very sophisticated unit that allows you to input a schedule with settings that best suits your everyday needs. These thermostats can help you save on the heating and cooling costs by adjusting the temperature throughout the day.

Why Use Programmable Thermostats?

When the heating or cooling in your home runs continuously, there is a lot of wasted energy used. Does the house need to be so warm when you are at work? Or in the middle of the night while you are sleeping? A programmable thermostat allows the temperature to adjust automatically during the day based on who is home. When no one is home, set the temperature at an energy-saving level then have the temperature return to your comfort level before you return home.

Mechanical Thermostats

These basic thermostats are pretty easy to install and operate by metal bars heating up and cooling down. Although these may be as accurate, they are cheaper than programmable thermostats. These thermostats are not as smartly operated as the programmable thermostats but are still widely used due to the simplicity of their operative functions. For these to be energy efficient, the homeowner must manually adjust them. However, it is still unwise to use these thermostats as every time your temperature rises by 1 degree you end up consuming 10% more energy!

Electronic Thermostats

Electric thermostats contain a sensor that controls the temperature and are programmable as well. You can control the thermostat from an app on your phone or check the temperature in your house at any time. These types of thermostats are often part of a whole-house control system which includes security, lights (indoor and outdoor), sprinklers, and thermostat.

With the right choice of the thermostat and a careful inspection of all the essential factors such as keeping track of your saving potential and making the correct and smart use of the thermostat options, you can save an enormous amount of energy and money too!

Steps to Take Before Turning on Your Air Conditioning

Good Deals Heating and Cooling air conditioner repairAir conditioners are mostly used during the summer months when the temperatures and humidity are high. During those hot months, most people use their air conditioners regularly. Spring is the time of year when the weather is in transition, so it means it’s time to make sure the air conditioner is working. Before turning on your air conditioner, here are a few steps to follow:

Look at the thermostat: the checking the thermostat is crucial, if it’s not working correctly, install a new, programmable thermostat to make the system more energy efficient.

Check the ductwork: Ductwork can become disconnected allowing air to escape making the whole system overwork.

Check air vents: the air vents around the home can be blocked. Toys, drapes, and furniture can block the air vents and affect the airflow.

Check the drain line: the drain line should be clear. Keep the drain clear and if clogged, clean it out.

Change air filter: At a minimum, the air filter should be changed before each heating and cooling season. Changing air filters should be on the TO DO list for every three months.

Check electrical circuit: before turning on the air conditioner, the circuit should be connected correctly.

Inspect the condenser unit: Any spring maintenance routine should include inspecting the outdoor condenser unit. It should be clear of other equipment and debris to enhance performance.

Insulate the refrigerant lines: the refrigerant lines need to be insulated to improve the system’s efficiency. Insulation repair is for professionals only.

Inspect the outdoor wiring: inspecting the electrical wire both outside and inside. Any wear or damage should be repaired and re-installed by a professional before using the air conditioner.

After making sure the indoor and outdoor equipment are working and connected securely, test the system.

  • Lower the thermostat temperature before turning the system on.
  • Listen and make sure the fan is running and the air coming out is cool. Let the system run until the indoor temperature cools off during summer.

If you don’t feel comfortable around electrical equipment then schedule an air conditioning maintenance appointment with an HVAC professional.

Is Your Air Conditioning Contributing to Ozone Depletion?

Good Deals Heating and Cooling air conditioning repairFor decades now, a variety of standard household appliances have used chemicals that are harmful to the environment. This practice has been a particular problem with air conditioners. The most common refrigerant, R-22, can do a lot of damage to the ozone if it leaks out into the atmosphere. For that reason, R-22 and other harmful refrigerants are being phased out. If your air conditioning unit uses these refrigerants, then it’s time to take action.

The ozone acts as a layer of sunscreen around the entire planet. Without it, the Earth would be exposed higher levels of ultraviolet rays from the sun, Instead of being absorbed by the ozone layer keeping the stratosphere cool, vastly increasing the effects of global warming. Without the ozone, we would be toast which is why governments all over the world are taking action against products which pose a threat to the ozone.

As of 2020, it will be illegal to manufacture any new air conditioning units using R-22 as a refrigerant. That means any units that rely on R-22 will have to be repaired using recycled parts. Repair costs for these older units will skyrocket, and only get higher as time goes on. A more cost-effective solution is to invest in a new unit now. Not only will you save yourself a small fortune in the long run, but you’ll also be doing your bit to help the environment.

There is a nameplate on all air-conditioning units, which state the type of refrigerant used. Check if yours uses R-22.  If so, start planning to make the switch to a new, more environmentally friendly unit. Many brands are already moving away from these harmful refrigerants, so even before the 2020 cutoff date. R-22 is already illegal in many countries. Make the switch today, and you can keep cool without heating up the planet- a win-win situation for everyone.
