"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

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.
