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.

Within a few minutes of leaving a voicemail on Sunday, I received a text from Shannon not only scheduling our repair for first thing Monday but also offering to bring over space heaters to keep us warm until then.

Dan went above and beyond by addressing a couple of other issues and educating us in the process. Without a doubt this was the best HVAC service ever! Kudos to a true community family business that genuinely cares about the welfare of their customers.

I asked to have a repairmen sent out, thinking it would be the next day. She asked a few questions about the HVAC system, age, etc. and said, "We can't get anyone out there today but we can probably fix the problem over the phone." After assuring me that if we couldn't, she would send someone the next morning, she spent over half an hour walking me through a few checks and procedures and we got the system up and running. So something I thought was going to cost a few hundred dollars or more, cost me nothing, because she wanted to save us a very cold night and the possibility of pipes freezing. Wow! A company that shows incredible integrity and professionalism, and really seems to care about the people they serve! This was the first time I'd called Davey, but their number is now in my phone and will be my first call in the future. Thank you, Dorothy!!!

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.

They did a wonderful job installing a ducted heat pump that would add cooling and heating to my upstairs bedrooms using discreet ceiling mounted ducts, with the efficiency of a large mini-split system. Jophrey came to my house to give me an estimate and within a day or two presented a few different options and explained their pros and cons. Once we had settled on an appropriate solution, they were able to start the work in a few days (I think they have same-day availability for emergencies, but there wasn't a rush on my job). The installers (Carlos, Daniel, Juan and Alex) reached out each day when they were on their way with a picture and identification so I knew when they were coming. They touched base at the start and end of each day to clarify the work they had done and answer any questions. They were always very courteous, polite and asked about any modifications in advance to always make sure I was going to be pleased with the final product. At the end of the job, the owner of the company, Justin, even came by to QC their work and walk me through the new system. I obtained five bids, and theirs was one of the most competitive. Good service, quality products and a reasonable price - what more could you ask for? They will absolutely be my vendor of choice for any HVAC work moving forward, and they should be for you too!
