"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

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.
