"Grove did a great job in presenting all options for our new AC system and potential air cleaning systems (without making any aggressive sales pitches), and then did a great job with installing the new system. The new system has been in place for a few weeks now and is working very well - great job by Grove."

"Best Air Quality and Restoration did a spectacular job! I can't say enough about the employees. They did an outstanding job! They were punctual,polite and followed social distancing protocols.They assessed the home and cleaned the air ducts quickly and efficiently. I am very pleased with their service and highly recommended this company. I purchased a new home and had them come clean the ducts to improve the homes environment. They showed me before and after pictures and I noticed a difference right away"

"Alan came on time and thoroughly evaluated my home's HVAC and duct system. He agreed that the duct work that I wanted done would likely solve the issue with my system and home. He was much more thorough that he could have been to satisfy my needs. I already had a quote for a much higher amount from Supreme Service Today who has been servicing my home for about three years. Suspecting that Supreme Service Today's quote was very high, I turned to Angi to get competitive bids. Since I had a bid at a much more reasonable price from Alan at One Hour Heating and Air, I contacted Supreme Service Today and asked for a price match. They were willing to match the much lower price from One Hour Heating and Air, so I gave the business to the HVAC contractor that I've been working with for a few years. Good deal! (: Soon I may break my ongoing contract with Supreme Service and come to One Hour Heating and Air !! :)"

Air Conditioning questions, answered by experts

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.
