"We have been using Delta Service for over 10 years. They have been great. They respond to any problems quickly and really helped us in a bind when the blower failed during a cold spell in February. They managed to repair the broken part when another vendor said it needed to be ordered and would be several days to week before it would be in. Their techs are knowledgeable and won't try and sell you unnecessary repairs. They give you options and weigh the costs and benefits. I highly recommend these guys."

"These guys are different from most other HVAC contractors we have used. They repaired an old furnace that we have, although other contractors merely told us we needed a new one. These people said the same thing (we need a new one) but, unlike the others, FIXED the one we have...which saved us a bunch of money and gave us time to consider replacement options. It is really refreshing to see an HVAC contractor whose sole motive isn't to upsell you on new equipment."

"They did a full furnace install for us about 8 years ago and have serviced it since. They are very honest and upfront about costs, potential problems and solutions. Reasonably priced as well. During the furnace install we also were having a separate problem with our A/C unit. Chuck spent 30 min fixing it with no charge and advised us that it could hold out for another few years instead of trying to sell us a new model (it still works today). Also, had them out to service the furnace last year after it seemed to have some glitchy performance. They spent about 30 min looking it over, made a minor adjustment, didn't find any other problems and didn't charge us. I've recommended them to family and will do so again."
