“I woke up to no hot water a few days ago. Excel Mechanical was quick to send Ivan out the next day and tell me what I already knew inside... it was time for a new tank. I picked out a Rheem tankless gas heater at Home Depot then Ivan got to work installing it the next day. He did a great job, beautifully installed!“

“Dylan is the best! Very professional, friendly, explains everything even if you ask several times. He is very patient and thorough. Dylan came to help with our air conditioning/air quality system and spent a lot of time making sure to my satisfaction ( I am the one with the sensitive nose) that the air smelled clean.
Dylan was so kind to give my dog Butter lots of pets (Butter if he could write a review would say Dylan is a great guy who gives the best belly rubs and is so greatful that with all his flying fur that he will make the air cleaner and non allergenic.“

“If you’re looking for a reliable local company, I highly recommend CoolAir! My new gas heater turned out to be a lemon, but Bill (the owner) and his team stuck with it until it was fixed. Bill went the extra mile with the manufacturer, and his office staff were always patient and kind, even when I was panicking. Thanks to their persistence, my system is finally running perfectly. It feels great to support a small business that truly cares about its customers!“

“We just bought a house a few weeks ago and didn't realize our oil gauge was not working correctly until about 4 o'clock when we came home from work to no heat and a 55° house. We called Mac Lellan as brand new customers and they were at our house filling our tank by 4:25 on a Friday. It was so greatly appreciated!“

“I had them come to my home to assess my unit. I trust Jason and Justin. They quoted me a new unit as my Tappan is over 29 yrs old. I can always count on them to come over immediately and the service is Outstanding. They are Honest People with very competitive rates. There is a reason they have been in business for so long.“
