"The DUCTZ team did an amazing job. They provided a VERY thorough cleaning of all of my ductwork and HVAC units, even down to the wires in the unit. They were ;professional, clean, and courteous in my home. I was worried that there would be dust or debris left after the cleaning, but they left no trace. I would 100% recommend DUCTZ to anyone in need of duct cleaning (and even those who didn't realize you need duct cleaning - it's much dirtier than you think back there). You'll be amazed at the results."

"I have a dual zone system and the air handler/heat pump unit on the 2nd floor was blowing hot air. I immediately looked up HVAC service in the Bel Air area and came upon Comfort Air. I initially chose this company based on the good reviews. I was told by the technician that based on the age of the unit and problem it was more cost effective to replace the unit instead of making a temporary fix. I agreed and after entertaining some estimates I chose Comfort Air. We negotiated a very reasonable price along with a quality unit. The installers were very professional and completed the work in about 4 hours. I would highly recommend Comfort Air for any Heat and Air Conditioning needs."

"It started off with requesting a quote through Best Air Quality and Restoration. The response time was great. The technician who showed up informed us in advance of his arrival, was very polite, followed Covid-19 safety protocols, was very thorough and did a great job. I also got the dryer vent cleaning which was the complete deal (going to the attic, removing the vent pipe and cleaning the debris). Some other companies claim they do dryer vent cleaning but only vacuum the dryer duct and do not perform the complete dryer vent cleaning which is more involved. I'm very happy with the service and this company and have already recommended them too many of my friends. Keep up the great service Best Air Quality and Restoration!"

"My AC was shot, dead. I had three objectives for my search; well, done, well priced and quick. Jason from SM contacted me almost immediately after I hit send on my Home Advisor request. That was Tuesday night. He came to my house the next morning provided a competitive quote (I needed AC but bought an entire system). It is Friday at 5:29 PM 90 degrees outside and 74 in my house, the job is done. Brian and Steve showed up for the install at 8:00 AM and were great. Thanks SM Mechanical and Home Advisor."

"Sunday 6/22 my mom's air conditioner was struggling. We called Aireserv who set up for their tech Bryson Bean to come out to mom's house. From the bright greeting smile as he introduced himself to the going over everything he was very professional and patient with all my questions. Highly recommend Aireserv for any of your heating and air conditioning issues. Thank you Bryson for being so you and personable."

Air Conditioning FAQs, answered by experts

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.
