"Aire Serv did a great job for me. Tuned up my main AC unit. I expected more charges but everything checked out fine. Thanks! The technician ran short of time, due to the rain. He could only get to one of the units and said they would follow up the next day to reschedule. Unfortunately, they did not follow up and I've not had the second unit completed."

"Quality Air has been my go to company for 10 years. They’ve helped me keep an old unit running without having to replace the whole thing until it was time to replace it. They’ve always responded quickly. All of their employees are very professional, helpful, kind and follow through."

"George was professional and friendly. He cleaned the air ducts throughout the house and included the vent covers. The machine was really loud, but efficient. He showed us how much dust and debris were removed. No wonder we were having allergies in the house. Within a few hours we noticed a difference in the air quality. Will definitely use Vent Service Pro in the future."

Three Jay Heating & Air started the way most good businesses do – with a conversation between people who saw something that needed fixing.\nOur three founders come from different worlds. One spent years in cybersecurity, learning that systems fail when people cut corners and that the details you ignore are always the ones that come back to bite you. Another came out of logistics, where meeting a deadline isn’t a courtesy – it’s the job. The third spent a decade in the field, hands-on, diagnosing and repairing problems in homes just like yours. Between the three of us, we’ve learned that doing this right means being organized, being honest, showing up when we say we will, and never walking away from a job we’re not proud of.\nWe named the company Three Jay because it represents the three partners who put their names

Air Conditioning questions, answered by experts

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.
