“The who team were very nice and knowledgeable in helping finishing my boiler system. I also had a heat pump installed. They are now my main hvac service provider.”
- Kris P.

“I needed a repair on one of the busiest days of summer with 98 degree temperatures. Not only were we able to get in same day, but within hours. They were also very reasonably priced for an emergency visit! My family and dogs THANK YOU!”

- Kimberlee S.

“My home needed a new air conditioner, the old system was two air conditioners one was 2 ton and the other was 2.5 ton. Jeff and his team designed a new single system with a capacity of 2.5 ton capacity. Their attention to detail went above and beyond what you normally get from HVAC Contractors. They designed a new ductwork system
with a high efficiency air filter that required very little horsepower to move the air through the system, resulting in a total system electricity consumption which was too good to believe. My system uses very little electricity resulting in a very low kwh/ton energy consumption. I am a retired industrial HVAC engineer, and I can tell you that Jeff and his team really paid a lot of attention to detail. I got 4 quotes from Contractors for my project, and only two were able to conduct a Home Load Analysis (one was done by Jeff and his team). One Contractor refused to do a load analysis and said the new system would be sized for 4.0 ton. I cannot say enough about the Jeff and his team on our project, they went out of their way to provide a very energy efficient air conditioner system for my home with a very efficient air filter with very little air pressure drop. Outstanding design & service.”

Jeff was Amazing! He explained everything to me, What he was going to do and Why. He is very knowledgeable and thorough! I appreciate the ladies that I talked to and how they kept me informed of the arrival time and the length of the appointment. I also liked the message I received before the technician arrived.

Why Are They Called Ductless Mini Splits?

They’re called ductless mini splits because they don’t require ductwork and consist of two main components—a compact indoor air handler and an outdoor compressor—connected by refrigerant lines. This “split” design allows for efficient, targeted heating and cooling in specific areas.
