They were Great!
Description of Work
DG Heating & Air Conditioning is simply the best! They seem to come from a time when customer service was the most important part of the job. After the previous heating company misdiagnosed the problem and I became somewhat suspicious, I called a trusted source and they recommended D & G Heating and Air Conditioning. Instead of needing a new furnace, I only needed a new gas valve and fan belt and a thorough cleaning at a cost of $465. That's quite difference from the thousands it would have cost for a new unit, as recommended previously. Eddie, was on time, courteous, clean, quiet and very efficient. He knew his job well and went right to the problem. Angela

Frankly I was not impressed with the overall experience. To get an estimate I had to make multiple calls between the office and John (owner). I spoke to John over the phone and explained what I was looking to do and then for him to come by my house to provide a more detailed estimate I had to call back to the office to speak to the manager there who handles John's calendar. Not a big deal as I can understand calendar management. On the day of the estimate though, John arrived (he was on time), but quickly walked through the house, was somewhat dismissive of my questions and then rushed out. He then gave me his card and asked me to email him with what we had talked about and he would reply with estimates. In effect, he took no notes of what the job would entail and then asked me to itemize the discussion and service options. I received his and quot;estimateand quot; 3 days later where he essentially just replied in line with prices for the items I listed in my email. No formal estimate, or proposal... just a few numbers he added in my email to him. So I cannot review D and H based on their work, they may do good work and this is what I learned from other reviews, but I just did not have a good experience or feeling about the estimate process, so I went with another provider.

Pros: Very friendly, and good at explaining how both the air handler and heat pump work together to both heat and cool our house. In spite of delays on the part of the general contractor and other subcontractors, they were prompt and courteous during the installation of the ceiling ductwork, registers and HVAC appliances (air handler in our tiny attic, heat pump outside in backyard). We really liked working with their lead technician Patrick, who was on top of everything onsite. Cons: The owners John and Mike didn't take time to discuss the best make and models of heat pump systems to best suit our house and usage patterns. Indeed, it was a struggle at times to get them to send us the model and serial numbers for the HVAC appliances, but when installation was complete, they finally handed over the manuals that came with the appliances. In addition, we needed to get invoice info for the air handler and heat pump into order to obtain energy rebates and tax credits; this was stipulated in our contract, too. Oddly enough, DG seemed to get cagey when we requested this info, sending only an energy efficiency certificate for the appliances. I guess they might not have wanted to see what they were getting as a subcontractor fee, but such and quot;secrecyand quot; seemed irrelevant to us (we already know that subs would get a portion, that's how they're paid, of course). They finished installation in mid-March 2010, and everything ran smoothly until December of that year. Suddenly, it seemed that the air conditioning (cold air) would start running, when we were expecting heating instead; heating would eventually return, but this seemed worrisome since it was winter. We contacted them, and it took them nearly 2 weeks to respond to us. It turned out to be expected behavior: that during especially cold (sub-freezing) temperatures the heat pump will temporarily pump heat (literally) into itself (thus cooling the house briefly) to warm its coils in order to function efficiently. However, it would've been helpful to have learned this sooner with a prompter response from DG.

DG installed an electrical heat pump based HVAC system in our house, as part of a major remodeling project in our house. We hadn't any sort of centralized heating beforehand.
