What is HVAC?

If you have been browsing our website, you are probably seeing this term on most of our pages. HVAC is the acronym for Heating, Ventilation, and Air Conditioning. It refers to your whole indoor climate equipment that consists of the heating system, air conditioner, ductwork, indoor air quality systems, registers, and other components.


Do I need heating or air conditioning maintenance?

Definitely. Maintenance is key to a highly efficient and top-performing HVAC system. We recommend scheduling comprehensive maintenance once or even twice a year to make sure your system will not fail during the seasons you need them most. Call Stay Cool Heating and Cooling and ask about our Residential Energy Savings Agreement. We offer either an annual or bi-annual service of HVAC systems. Our team also suggests doing some maintenance work yourself like cleaning the outdoor unit, changing the filter every three or six months, or as specified in your manufacturer warranty.


Why is it important to change the filter regularly?

A dirty filter restricts the flow of air from your heater or AC. It also puts a strain on your HVAC and can result in a complete system break down. Additionally, dirty filters are found to be the No.1 source of indoor air pollution, aggravating allergy symptoms or just making it hard to breathe for you and your family.


How do I improve the efficiency of my heater or AC?

Improving HVAC efficiency is easy with regular comprehensive maintenance. Sign up for our Residential Energy Savings Agreement, so we can provide you with thorough inspections and precise tune-ups annually or bi-annually. Our comprehensive HVAC maintenance offers several benefits to homeowners and business owners such as increased system efficiency, lower utility bills, reduced occurrence of major problems, improved indoor air quality, and extended lifespan of the heater or AC. Additionally, regular maintenance preserves the manufacturer’s warranty.


How do I know my heater or AC has an existing warranty?

Most manufacturers give out at least two to five years warranty. If you don’t know the actual age of your heater or air conditioner, take a look at the information sticker of the unit. For furnaces, this sticker is usually found on the sidewall inside the top shelf of the unit. Information stickers of air conditioners and heat pumps, on the other hand, are usually found on the system’s outdoor unit. Some brands can also find this out for you. Just call and give them your serial number and they will track down if your unit is still under warranty. Our technicians can help you, too, via Get Warranty form.


Does the sound of my heater or AC indicate a problem?

Yes. Loud, rattling, banging, or whistling noises when you turn on the heater or air conditioning is a definite sign that there is a problem with the system. While only a few HVAC can deliver silent operation, the sound of your HVAC should only be minimal that you gradually forget that it is making a sound at all. If you hear strange noises from your heater or AC, the problem might be due to an obstruction in the outer unit or a malfunction of the inner components. Call our Gwinnett County heating and cooling experts for a more accurate diagnosis and cost-effective repairs.


What other signs of HVAC problems should I be aware of?

Aside from loud noises, there are other signs of heater and AC problems you should look out for, so you will know when to call us for a service.

Other indications of HVAC issues include:

  • Poor airflow
  • The heater or AC is taking a long time to heat or cool your home
  • Unable to read thermostat temperature
  • Cycling frequently
  • Uneven temperatures
  • Strange odors such as a musty smell

If you notice one or more of these warning signs, reach out to us right away. Our team is available for emergency repairs and ensures a job done right the first time.


What is the ideal thermostat temperature?

The perfect thermostat temperature for your home will depend on the season and your personal preference. However, if you are asking because you want to keep your energy cost at a minimum, we suggest keeping the temperature between 75° and 80°F during the summer and between 68° and 72°F in the winter. We also recommend that you don’t make any drastic changes in your thermostat temperature when you leave your home. Setting it back by more than 5°F will cause your unit to work harder, increasing your energy bills.


How do I know if my AC is the right size for my home?

Whether you are installing an AC for the first time or replacing an old, worn-out unit, let our cooling experts help you. Contrary to popular opinion, a bigger AC does not necessarily mean that it would give you the level of indoor comfort you need. When your air conditioner is too big for your home, it could only cost you more. If it is too small, however, the AC will ultimately fail to provide even temperatures. That is why enlisting the help of our pros is crucial. At Stay Cool Heating and Cooling, we will thoroughly assess your home, your unique needs, and budget to find the best cooling system for you and your family.


Is there a way to eliminate indoor odors?

If there is a persistent odor in your home, air fresheners and candles won’t help. Get in touch with us today, so we can find the exact source of the problem first. Often, certain particulates in the home such as airborne bacteria, pet odors, or cigarette smoke can leave odors no matter how many times you clean. If this is the issue, we can install a UV light system for you. The exact system used in most hospitals and medical facilities, UV light units target and eliminate all airborne particles including any trace of odor. However, if the source of the odor is mold or mildew growth from poor ventilation and increased humidity, we can mitigate the molds and install a dehumidifier system to prevent them from coming back.


How do I know if my home has poor air quality?

According to the EPA, indoor air is actually 100 times more polluted than outdoor air. There are many factors that contribute to this such as the presence of pollutants and airborne bacteria, poor ventilation, as well as too much or too little humidity.

Some signs of poor indoor air quality include:

  • Aggravated allergy or asthma symptoms
  • Dryness or irritation of the eyes, nose, throat, and skin
  • Chronic fatigue and headaches
  • Mold or mildew growth
  • Damage to your hardwood flooring as well as wood or leather furniture

If you also live with pets or a smoker, it is highly likely that you need to improve your air quality. To be sure, our experts at Stay Cool Heating and Cooling can test your home for air quality issues. We will provide you with a Home Health Report card after the testing that includes our diagnosis and indoor air quality system recommendations.
