"From the moment we inquired about services to job completion, we had a great experience working with Air Quality Concepts for our HVAC air duct and dryer vent cleaning. The owner Charles was incredibly prompt with communication and took the time to answer all our questions about the cleaning process prior to scheduling. We were so impressed by how personable, hard-working, thorough, and efficient our technicians Austin and Michael were when they cleaned our two HVAC systems. They were very attentive to the issues we have been having with our indoor air quality as we navigate mold remediation and health concerns. The company’s customer care was genuine and so appreciated, and the cost of services was very reasonable. We already feel more comfortable in our home knowing we are breathing cleaner air! I highly recommend Air Quality Concepts if you are looking to improve the air quality of your home!"

"Dominion Services replaced my 30-year old HVAC system (the outside compressor, and the inside air handler) with a modern one having a 50% increased efficiency rating. The quality of their work is high (four friendly employees with more than 100+ years' combined experience were involved) and have good flexibility to adjust to my work schedule. They easily adapted the new system to the existing hook-ups, and were flexible in their selection among alternate, reliable replacement HVAC systems. The replacement cost was well within the range of the national average. I recommend contacting Dominion Services for insight into any HVAC issue."

"Lahcen is an excellent HVAC technician! He quickly diagnosed the issue with my AC unit and clearly explained what was causing an error in my AC unit and while he was diagnosing the main issue, he checked my filter he found out it was upside down. Professional, knowledgeable, and honest. I highly recommend him to anyone needing HVAC service."

Heating and Air Conditioning FAQs, answered by experts

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.
