"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!"

"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.

"Caliber did a wonderful job fixing my ac. He was prompt. He was knowledgeable. He got my ac to work, and his prices were fair. The only reason I didn't give him a perfect 5 stars is because my ac has a leak and we would need to schedule another appt to find and fix the leak. I would have preferred that it was completed at the original appt but as he advised, it would take quite some time to find the leak and he would need more to do a thorough job. I appreciated his honesty. I would definitely recommend Caliber. And I will be calling back if I ever have issues again. I may have found my new hvac guy."

"Adam and Nate were very prompt, polite and thorough. They replaced the two hvac systems at my home. They worked quietly and cleaned up after themselves. They provided me the best bid with the lowest cost and the earliest delivery time and they delivered. The job was done on time and on budget. I would definitely use AAC again."

Heating and Air Conditioning FAQs, answered by experts

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.
