"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."

"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

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.
