"Erik with Oasis heating LLC is a very professional and efficient installer. Anyone can provide a service, but it is a welcome, uncommon experience to have a superior service provider! I believe that any other business Eric would be a part of he will provide the same superior service.
It was a pleasure working with him. While it is never a pleasure to spend money on something like this, Eric relieved the pressure by his kind and efficient work ethic.
He has vowed to return to fine-tune any request regarding my new system. I will refer and I would recommend him to any of my friends or anyone who would ask. Thank you Erik!"

D.P. Google Review


"I had another HVAC company send a service pro to do two boiler tuneups for my duplex. He immediately said a vent was illegally installed on one, and the other he wouldn’t touch. I was suspicious, because he immediately tried to sell me two new boilers. My home inspector never noticed the ‘illegal’ problem prior to purchase of the house. Nor did previous service professionals who replaced minor components.
Erik from Oasis fixed a minor electrical connection problem and got both boilers ready to go for the 2021 heating season. I inquired about a ballpark estimate for new 95% efficiency boilers. Erik explained that the overall replacement cost would not produce substantial savings. From my experience working in factories, maintaining old equipment (cast iron boilers in my case) is cost effective. Good house insulation also helps. I’ve been happy with my heating costs over recent years. I appreciate Erik’s honesty and overall evaluation of the economics of maintaining my current system."

"I wholeheatedly endorse Erik and Oasis Heating & Air Conditioning. He is honest, trustworthy, skilled, and reliable. He provided same day services, he fixed the problem, he took the time to explain and teach me about my system, and he was all around kind and professional. If you're overwhelmend and thinking, who do I hire (like I was)? I just saved you the time and anxiety. Call Erik. Being good at your job while also being a good human goes a long way. 10/10"
