"They didn't come on time at all.  The issue I had was that they had a price advertised for a system check and when they came they said that I had two different air conditioning units and it would be two different prices.  I felt that was a bit misleading and they didn't say that when I called to make the appointment. The guy that came was fine.  He was great.  I was happy with the service.  I just felt mislead."

"We have used Absolute Comfort Heating and Air for over a year now. Each time we have used their services, Shawn has been able to find the cause of the issues with our systems without having to order major parts or replace the old systems. Shawn and his team are professional, dependable, trustworthy, honest, and the ABSOLUTE best out there. We were so lucky to find these guys after years of having bad experience with other companies. They went above and beyond to ensure our family (with new baby) was warm in our home- (ie: they came out the same day that we called and made a trip after hours to fix another issue) so thankful guys!"

"From start to finish a great experience! Called with no air conditioning yesterday, a Friday holiday weekend. The lady that answered the worked wonders and found tech close by that could come the next morning. I received a call the tech was going to be earlier than expected. Great news on a hot day with no air. The service was efficient and fair priced. Within a hour my unit was up and running again. The sales office followed up right after to schedule a time to look a future options since my unit is getting up there in age. No pushy sales. Professional, quality service. I will use them in the future and highly recommend this company."

"EXCELLENT! Sent a message via Angie's List to AAD and received an almost immediate replay from owner, Kevin. Explained above and HE asked if he could come out the next morning! Arrived promptly, checked airflow and agreed something was amiss. Normally, AAD only guaranteed their dryer exhaust cleaning for 4 months, however, no charge was requested. Kevin found and showed me that the vertical air flow pipe from dryer to roof was detached from roof vent, and air was being issued to attic. Kevin re-secured the pipe to the roof vent and all was well. Kevin also asked if HE could re-clean the vent pipe with his mobile super vacuum, which he did. The pipe was clean as minimal lint found. It was outstanding display of customer service and I recommend him highly because of his concern for the customer."

"They came out because our unit was not blowing cold air. The tech found a leak in the system and scheduled a time to replace the part. He refilled our refrigerant that day which was included in the price of the part. My family has used this company for years with no complaints."

Air Conditioning questions, answered by experts

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.
