Frequently Asked Questions

If you’re not sure if you need to schedule service, or if you’re just looking for some answer to some random questions about your AC system, we got you covered! Check out our list of topics and questions related to Heating, Air Conditioning, Air Quality, and more below!

What does HVAC stand for?
HVAC stands for “heating, ventilation and air conditioning.”
Should I close a door to conserve electricity?

No. Air conditioning systems are programmed to cool and or heat a certain number of square feet. When the doors are closed, it disrupts the flow of air and can cause the air conditioning to run inefficiently.

Should I use a programmable thermostat?
Yes! Programmable thermostats are electric, which allows you to set a much more exact temperature than mercury thermostats. You can also automatically change the temperature very easily throughout the day without even being home.
How do I troubleshoot my AC unit?

Here are some simple procedures you can perform before opting for the expense of a service call:

  • Check disconnect switches (indoor and outdoor if you have a split system).
  • Make sure that circuit breakers are ON and that fuses have not blown.
    Check for sufficient airflow.
  • Make sure air filters are clean and that supply-air and return-air grilles are open and unobstructed.
  • Check the settings on your thermostat. If you want cooling, make sure the temperature control selector is set below room temperature and the SYSTEM switch is on the COOL or AUTO position.
  • If you want heat, make sure the temperature control selector is set above room temperature and the SYSTEM switch is at HEAT or AUTO.
  • Make sure the FAN switch should be set at AUTO.

How do I keep my AC system working well?
Inspect and change your filter as needed and flush out the drain system on a monthly basis.

Tip: Just say “Hey Google” or “Hey Siri” – set reminder > change AC filter > on the 30th every month

Why should I schedule AC tune-ups?
Regularly scheduled tune-ups ensure that your heating or cooling system is running as efficiently as it should. Staying on top of any potential issues means less repair work, lower energy bills, and a safer system for your health.
How do I flush out my drain system?
If your air conditioning drain line has a tee installed, remove the cap and pour one gallon of hot water down the drain slowly so water will not back up into the overflow shut off. Following the hot water, a cup of vinegar may be added to inhibit future buildup in the drain line.
Should I turn down the thermostat if it is not cooling?
No, turning the temperature down further will not make it cool any better and may only compound the problem. If your air conditioner does not seem to be cooling, there may be a problem with its operation and a professional should be called to check the system.
What is the cost of a new HVAC system?

There are so many different makers and models available, that it completely depends on what is right for your home. Your home’s needs would need to be evaluated for a price suggestion. However, if you have an idea of what brands you would prefer, see the chart below to get a rough estimate on the price.

Can I get a Federal Tax Credit if buying a new AC system?
We recommend speaking to your tax accountant about whether your new air conditioning is eligible for the Federal Tax Credit. We provide you with the paperwork necessary to prove the installation of a qualifying system. Just for further clarification, the Federal Tax Credit is worth 30% of the installed cost, with a maximum credit of $1500. Remember, this is not a deduction, but a credit.

Im not going to write a 5 page essay on why you need to use this company. My elderly parents live with me and this company responds quick, is fairly priced, and is no nonsense. Robert is amazing and tells you the truth without fabricating other charges. You need your A/C fixed, dont waste your time with other companies. American Air Repair should be the only call you make. Please trust me on that.
