They've helped with everything from a simple AC recharge to installing a completely new heating and air conditioning system, and every experience has been excellent. But the best thing they ever did for me was properly balancing my HVAC system so the upstairs and downstairs temperatures finally became equal. That made a huge difference in the comfort of our home. I highly recommend them for their professionalism, knowledge, and quality work." On a personal note, they are also a very kind and caring family who truly treat people the right way. It's rare to find a company with this level of professionalism and genuine care for their customers. I highly recommend them.

Stay away from these guys or at the very least get multiple quotes. I called trying to get an…read moreestimate to replace a boiler when it suddenly died and we had no hot water (and a small child). Talked to Jim and he was nice at first until he was supposed to come for the quote and something I said made him thinking I was getting the job quotted by more than one person. I wasn't getting multiple quotes, in fact I was having a hard time finding anyone who actually dealt with boilers. He specifically said he wasn't interested in coming to give a quote if others were involved and when I tried to tell there weren't any others he basically hung up on me. Called him back immediately 2x and left messages with 0 response. Completely unprofessional. If I was actually bidding the job out (which I wasn't) only someone with something to hide would be that concerned so be wary of any quote you get from these guys. Crazy shady and frankly glad we found someone else ‐‐------------------ Jim, in response to your reply you should check your messages again. Here's the text message I sent you after you hung up on me and after I called you back to try to explain and you refused to answer. Its clearly sent to the number you listed...

I received a referral for this company from a trusted friend. I immediately advised my husband to…read morecall this company based on my friend's experience. To my dismay, I was shocked and thoroughly disappointed with the level of customer service that my husband received just trying to schedule an appointment. I'm very big on customer service and this company failed to meet my expectations early in the process. As a potential customer, my husband and I didn't expect to be treated in such a demeaning manner. During the process of scheduling an appointment, at my friend's request, we notified the representative that she referred us. Immediately, in a rude tone, the representative states, "It's still going to be a $175 service charge". Then he went on to say, "I'm not going to be driving all around for free." It was never implied or requested that they provide a service or commute for free. Why would you assume that by simply saying who referred your company that we were expecting anything short of the same quality service that you provided the person that referred you? We never expressed any issues with the service charge nor were we expecting a discount for saying someone referred your company to us. One would think that the person making the referral would benefit not the person being referred anyway!
