Customers say: Super punctual

"Very warm weather.  Home of elderly mother.  A/C stopped working the evening before.  A quick call to Hoff the following morning received a very prompt response that day.  Mike diagnosed the problem immediately, telephoned me with thorough explanation of problem and cost, and took care of the matter in a short time.

I have no doubt that Mike remained long enough to ensure that his repair was appropriate, and that no other repairs were necessary.  There were no other A/C failures during the remainder of the cooling season.
Highly recommended."

"If you're looking for friendly and exceptional service for your Heating and Cooling needs, I highly recommend Armor Air! Ever since we moved into our home several years ago, we dreaded the winter dryness (our home routinely would be anywhere from 25-29% humidity in the winter, and sometimes even lower. We were constantly sick, waking up with a sore throat, and frequent nose bleeds. I saw a video on Instagram of the Armor Air team and they looked like a bunch of really nice people, so I investigated and saw how many people had great things to say about the company. We had them come out and give us a quote on a whole home humidification system, and Robert was very friendly, professional and worked with us to get a system setup for our home. A few days later, Kameron came out and installed the system and he did an awesome job! The last time we had another HVAC company come out and do work on our system, they left a giant mess, but not Kameron. You couldn't even tell he was there! Now,"

Heating and Air Conditioning FAQs, answered by experts

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.

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.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

Your central A/C unit should be professionally serviced and inspected at least once a year to ensure it operates properly and efficiently. This is best done before the peak cooling season. A full-service inspection by a qualified pro will typically include checking safety components for issues like carbon monoxide leaks, verifying cooling components and coolant levels, and inspecting electrical parts like fuses and wiring. Regular servicing enhances efficiency, mitigates potential problems, and maintains optimal performance. Because AC systems contain hazardous refrigerant, professional handling is essential.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.
