"We had a great experience with Cool R Us. Our first contact was with Josh, who arrived at our home on time and completely prepared. He was very personable and truly professional, and quickly put us at ease. He asked questions to see what our priorities were and explained what his recommendations were and what each particular HVAC unit would do for our home environment. There was no pressure to decide immediately and he quickly sent us an online quote for all of the units that he recommended for our needs. Once we decided, we were given a very fair price and the installation was set up to accommodate our schedule. The installation technicians let us know they were on their way. They arrived and worked quickly and efficiently to remove the old unit and install the new one. These gentlemen were also very personable and professional and obviously, very knowledgeable. When installation was done, they did a complete clean-up and left our home spotless. Adem helped us to set up our digital thermostat and explained how to use the thermostat, which was one of our major concerns. He assured us that an answer to any questions we had was only a quick phone call away. After our first day of using our new unit, the humidity level in our home dropped appreciably and the air felt so much cleaner. We are very pleased with our purchase and highly recommend Cool R Us."

"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

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.
