Customer Testimonials

This company lives up to it's good reputation and excellent customer service. Our long time technician , Roger is a true professional , knowledgeable, and extremely courteous. He is a real credit to his company.

I needed a new boiler (expensive ) Oliver was in line with the other estimates i received so decision was not based just on price. the guys arrived on time and were thorough and clean. in and out in a day. haven't had to run the system since the weather changed since i had it installed. Hope when it's time to turn system on we don't have any issues. I am confident that Oliver will take care of any issues.

New entry for Nick, Electrical Technician Who serviced my whole home generated and Lisa, Customer Service who assisted in scheduling. Both were very professional, polite, and efficient.

Oliver has done several installations (air conditioner, gas heater, gas hot water heater, and a whole house generator) and performed service for us over the past 15 years. We have been extremely satisfied with both installations and service. They have always been efficient and professional.
