The installation went great - after having a bad experience with a new hvac system at my old house on the east coast, these guys clearly knew what they were doing and everything looked and worked great when they were done. Thus far the system has done a bang-up job, with no problems keeping the set temperatures between the 0-degree days last winter or the high-90s days this summer. And the high-efficiency system means my gas and electric usage have gone way down, compared to the usage of the old system.

It's been a little over a year and after speaking with two other HVAC companies, and making calls…read moreto some of my friends in the business, and with a ton of home remodeling experience under my belt, we discussed this at the house and I was prompted to write this review. We had a water leak in my twelve year old 96% efficient Amana furnace and I placed a call to Davey. Dorothy was very courteous sent out her son Junior to look at what was going on. He told me he was going to condemn my furnace though there was no signs of aerial contamination. I told him I'll go out and buy two expensive meters and they both showed ZERO contamination! Ok, Junior then said the furnace would be covered under replacement warranty as the heat exchanger was cracked. He talked to the local dispatcher and they had a unit in stock. I was then told by Junior that it would cost me THIRTY FIVE HUNDRED to get the job done. I was flabbergasted at the price! This was for labor! Unbelievable! Ok it was winter and cold temps needed to be handled so I told him let's do it. Junior returned and started installing all the while informing me that it would cost me another EIGHT HUNDRED! I told him no way! Mind you, my old unit was removed and brought downtown. He called his office and they backed off on the additional eight hundred. I left Junior alone and he put together the new furnace and installed it! It was not straight, not plumbed and he left after the furnace was running. I called Dorothy and COMPLAINED! She sent Senior out and he straightened things out. The inspector came by and failed the inspection. Senior came out again and touched up all the work. Senior had to come by a third time to rewire the condensate pump... to code! That final time he came, I could tell he was PO'ed at returning and never said a darn word to me. No respect at all! Bottom line, I was ripped off to high heaven. Thirty five hundred... for the work done? Maybe they get this from other uneducated customers but the unit was under warranty, the whole installation with labor should have cost me $2000 at MOST! I found an unbelievably reputable HVAC and they have so far treated me with respect and professionalism especially when it comes to pricing and top notch customer service. Just had to share this with potential customers here in the area.

My wife is in Hospice care and I am 73 years old. I accepted the estimate thinking that it must be a complicated job. I also didn't want to have a parade of plumbers inspecting the problem to get multiple quotes. I also feared the pipes could burst soon, so I felt a sense of urgency. But I accepted the estimate. One hour and 15 minutes into the job, the plumber told me the job was done. I was surprised and angry. I asked him if they always charge $600 PER HOUR ( I included some travel time in the calculation).. He told me he doesn't set the prices.

One of the others (Tnt Mechanical) scheduled first, and arrived in a black pickup truck with no identifying information, no uniform or company logo shirt, no business card. The number of scammers in our neighborhood is on the rise so I said no thank you and asked him to leave. Then Bluestar called me to set up a time; when they arrived it was more as I expect from a trusted business: company van, company uniform, business card, etc. Ivan was very friendly, knowledgeable and professional. He found a coolant leak in my system within minutes, showed it bubbling through leak detector fluid, and wrote up an estimate to repair the leak plus recharge the coolant. With a discount for cash, it was a very reasonable price and I agreed. He went to work right away. About an hour later he'd finished and took me around to inspect what he'd done, explaining everything. This really helped me feel at ease with the quality of the work, and that nothing had been done that wasn't necessary. He even helped show me some things about my furnace that I had questions about, not related to the AC work. Ivan responded quickly, got us repaired quickly at a reasonable price, and left me with feelings of trust and satisfaction. Next time I have any problems with my furnace or AC, I'll know to call Bluestar first... a great experience.
