Critical: Responsiveness Website claims same day service but when you call they tell you they are no longer taking new clients. Do not call this business unless you are already under contract with them they do not want new business and are very rude about it

I have been a customer of Alliance for almost 20 years. They installed the HVAC systems in my present and former residences and have maintained them through the years. The quality of their products, and their level of customer service are both excellent. I highly recommend them. Services: Installation, HVAC system maintenance

Called on a FRI for a consultation for a very old forced air furnace replacement which began leaking oil and emitting odor in residence. Gave complete information of the situation and that I was needing to know my choices, costs and time frame for completion. Received a call 30 minutes later from Bret, a polite man who wanted clarification. I repeated to him the situation.

To an annoyance of mine because I understood the cause of the leak (the 30 year old furnace), he stated I should contact the fuel delivery company about the leak, and that they didn't replace oil furnaces and only to natural gas). There was no "but I can be out to discuss gas replacement" in that or the next sentence. There was moment of uncomfortable odd quietness which I ended with. well can you consult on a gas replacement?

He said yes politely and scheduled for mid morning the upcoming MON. FASTFORWARD. MON comes, Bret calls 45 minutes prior to appointment. He politely states: need to cancel, they have been inundated with emergencies. Again there is an odd silence without a follow up of "but I can reschedule to (fill in the blank). This prolongs the uncomfortable silence.

But wait! He then states AGAIN to my annoyance: we don't do oil replacements. That is all I needed to hear, you aren't wasting my time any further. For a professional HVAC mechanical engineering company to behave this way is unacceptable. What could be more urgent than pricing out a replacement for a 30 year old furnace emitting heating oil odors?

There were so many other emergencies that made it impossible to spend 30 minutes as scheduled so you could provide the requested information and submit it a few days later? Move along to a more detail orientated business.

We had Victor come to our home to fix the heating. From the moment he called us to the completion of the work he could not have been nicer. Work was done in a timely manner and done well. I would recommend Alliance to anyone. A+++++ Service: Heating system repair

Alliance is first rate. They're professional and punctual. We'd been through two HVAC companies which screwed up repeatedly. Alliance has been much better and documents all their work in detail. Highly recommend.

I recently had an issue with my air conditioning and even though I was having a maintenance service later in the week, Alliance sent a service person out to my house the next day to correct the problem. It was during the super hot weather so the immediate attention to my lack of air conditioning was very much appreciated. I would definitely recommend Alliance.

We have been customers of Alliance for over five years. They converted our heat from oil to gas and replaced our A/C system. We have been very happy with the installations and their service. I have recommended them to friends and family and will continue to do so.

Alliance Heating and Air has taken care of us for the last 5 years. They have installed and upgraded both our air and heating systems. They are professional and fairly priced/ I give them 5 stars!
