“We have been loyal customers of Haller for 18 yrs and have always been more than happy with their installations and maintenance policies. Jonathon serviced our HVAC units today and explained everything in detail as far as the health of the systems and any recommendations to be made. Having a service contract has proved invaluable in getting swift repairs when problems strike. I highly recommend this company to everyone.”

“On a Saturday my furnace quit working and I called my company but for them it was an emergency call. So I called Haller and they came right away, the furnace guy was very nice, explained the problem and made suggestions for and issue that needed to be resolved. And Saturday was not an emergency call for Haller.”
