"ECC is AWESOME!! From talking with Lisa, who scheduled EVERYTHING!! to Ed the gentleman who came out and estimated the job, to Tony, his son and Jane (the installers) everything was seamless!! The communication was EXCELLENT!! Lisa is excellent at keeping me informed about the process and following up when things were done. I can’t say enough about Tony and his crew!! He went above and beyond my expectations! He even RE-routed a condensation pipe to the gutter so it wouldn’t keep dripping onto my shingles!! Just an amazing company!! Would ( and have) recommend them to everyone I know for their HVAC needs"

"We could not be happier with choosing Unique Indoor Comfort for our new HVAC system. We found this company by being referred by a client of my husbands. The original duct work in our house was extremely undersized, over working our unit and not creating good airflow to reach the third floor of our town home. Reni came out to our home, and took the time to explain to me options with Unique to really make our new HVAC unit/system efficient and comfortable temperatures in our house. I really appreciated his kindness and patience with me with all my questions. Unique was able to get us scheduled within a week or finalizing the contract, just in time in end of April when the first heat wave hit. It has been almost two months now since Henry and Matt installed our new HVAC system (they both were friendly and did an excellent job) and we are truly enjoying it. With a new baby in the house, it is a relief to have this new unit and ability to cool down our house quickly and efficiently. I know it is a lot interviewing and getting quotes from different HVAC companies - it is a big investment. This company truly stood out for us and were able to work with our budget and our needs for our home. They were the only company who proposed how we could add an additional vent to allow more airflow, and to redo the duct work to the proper sizing for our house and up to code. We are very grateful and HIGHLY recommend Unique. Thank you Reni, Matt and Henry again!"

"We have used Gen3 on a couple of different jobs. They installed a new circuit breaker, two ceiling fans, redid all of our outlets and installed a common wire for our HVAC. Each time we reach out to them, they respond promptly and send out competent, professional, and courteous people. They make sure they wear booties and cover up furniture when necessary. I have recommended Gen3 to my friends and family as well. Cannot recommend them enough!"

"This company is excellent. On Monday my oil furnace broke down and by Wednesday, I have a new heater and it was also converted to gas instead of oil. The two technicians, Josh and Justin were so efficient and very knowledgeable. What a pleasure to do business with a company that knows how to satify its customers. I will definetely refer this company for any HVAC services. Thank you"

"Great company run by friendly people. Joe and his team know their stuff. Deborah is a pleasure to speak to on the phone. I first called due to some weird behavior with my HVAC and wanted them to come take a look. Before they arrived, the HVAC started working ok again. I called them back and when I told them what was going on, they explained that there was nothing wrong and the weird behavior I explained was actually normal based on what I had my thermostat set to. No visit and no fee required. A lot of other service companies might have urged a visit and charged me the fee. I then hired them for a regular maintenance service contract, and they have been fantastic. Always show up on time.

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

Heating and Air Conditioning FAQs, answered by experts

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.

Troubleshooting common issues with your AC often sheds light on a problem with the compressor. Signs that you need to replace a bad compressor include your AC blowing warm air, short cycling (turning on and off), making strange noises, and blowing less air overall. Since these problems can stem from several areas of your AC, always call a local AC repair team to confirm it's the compressor.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.
