"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"

"Unique is true to their name. What a great company! I needed a new HVAC system. Curt from sales came to my house and did a very thorough evaluation of my existing HVAC system. He painstakingly took pictures of my system, took several measurements, and both asked and answered a myriad of questions in order to ensure I would have the right system installed. In addition, Curt told me to call or text him with any questions. When I did so, he answered me immediately. He provided me with different options to fit my budget, and made sure I was confident in my ultimate purchasing decision. When it was time for the installation to be performed, installers Bruce and Jeff were tops! They did their own evaluation, and made some observations and suggestions that helped my new system function optimally. I'm sitting in my warm house as I write this, with a great new HVAC system, and a company I can continue to rely on in the future to keep my new system running at it's best. I look forward to the warmer weather for various reasons of course, but I will enjoy having a house that stays cool for a change! Do your homework and get your estimates from other companies. You'll find as did I, that Unique goes above and beyond relative to other companies. They have an old school customer first mentality that is most welcome in an age where it's not always easy to find good companies. Kudos!"

"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"

"

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.

"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 your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.
