"David Gray installed my heat pump sometime ago. I have always signed up for the maintenance packet. A guy came out and found a non-working part. It seemed to be working properly but wasn't. Kevin found the nonworking part. Then William installed the part and I see a difference in the comfort level. They ordered the part and within 48 hours had it installed. I have 10 year parts and labor so this cost me nothing. Kevin saved me a ton of money. I am impressed with their customer service and have used them for over 17 years now. Kevin found the problem and William completed the repair. Teamwork! Thanks fellas! I - and my family - appreciate all your good work!"

"Elmer came out within less than an hour from the time of quote. He charged exactly what he said he would and was transparent about prices prior to making fixes. He replaces the capacitor and then turns out the outdoor motor fan was broken, he went out of his was to get us a preowned part the same day to save us some money. No one loves spending the extra money, but overall the experience was pleasant. He was professional, timely, and our AC is now up and running."

"Our AC unit quit working last May. We met & received bids from several franchises in Jacksonville, but were not satisfied. After meeting with Thomas Measday we decided to support his local small business. Thomas & team are honest, professional and took time to explain and answer all our questions. They took under 5 hours to install a complete new system!! It’s been a year and we are completely satisfied. We highly recommend Measday as they are a 5 star company."

Heating and Air Conditioning questions, answered by experts

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.

No, not all HVAC systems have a fresh air intake, but there are many advantages to having one. For example, a fresh air intake can boost the air quality inside your home and help your furnace run more effectively. Plus, it can make your house more energy efficient, possibly saving you money on your utility costs.

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.
