"There is no other company I'd rather have installing and servicing my air condiition needs. I've been working with Ray and his family for over ten years. I know I call always count of them. I can call them and explain what I'm encountering and they know exactly what is happening and how to fix it. I wil say that five starts or a ten out of ten rating isn't enough. This company is head and shoulders above the competition. A top notch company who carees about their customers. I highly recommend them to anyone."

"Quick response and kept me updated on status of repair. Have used Aegis twice after follow up for a second opinion. By far best HVAC I’ve used. Fast , effective and only does work that is needed. Aegis will be my first call going forward. Thanks to Michael and his team!"

"Josh was the tech that came out. He was very professional and clean. He was courteous and on time. He spoke clearly about what was going on with the A/C. He had everything he needed right then and there to find out what was wrong. Also, the problem should be fixed in about 2 days which is super fast compared to my experience with other repair companies. I would defiantly recommend."

"Sooner heat and Air did some repairs on my HVAC system. The repairs had to be done, because the company that did the install did not put it to code and it had to be redone. Their prices were fair and the service and experience were top notch. I highly recommend this company for all of your HVAC needs!"

"The two guys that showed up were very polite and professional and had the job done in no time flat. I was amazed at how long it took. I would recommend this company to anyone who has electrical problems. The only problem is that the service charge is too much."

Heating and Air Conditioning questions, answered by experts

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.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.
