"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.

"My new HVAC system failed at beginning of summer . They worked with me to fix and resolve the problem . The last visit with their technician Hunter went well. He took the time to explain and show us the different filters that we need to monitor. Thank you Hunter , Tyler and AC techs. I canâ t live without AC. Otherwise I drip with sweat . No Florida retirement for me ."

Heating and Air Conditioning FAQs, answered by experts

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.
