Dennco Commercial Heating & Air Conditioning

I am a commercial property manager and I absolutely beleive that DENNCO is a great HVAC company. They are responsive, extremely knowledgeable, always on time and they get the job done. Love their services and I am grateful to have them around when we need them.

I would suggest you go elsewhere. I made what I thought was a legitimate complaint in writing to the owner about being overcharged for both time and the fact the one unit was no longer working after service and I was charged for them to come out and reconnect a wire. I never received a response them.

Fantastic service and response. Excellent work. Reasonable prices. This company is very well run and they do what they say they will do. I have been a satisfied customer for years.
