    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.

Manny assessed the situation before arriving and was here and gone in about 20mins. It's so much quieter now! Highly recommend this business.

    I've been using Summit since ~2018 to handle my furnace maintenance. This summer I had them out to…read moredo a tuneup on my two A/C units. I mentioned to the tech that the upstairs didn't get quite as cold as I would like; while I suspected some of that could be system/ductwork limitations, he suggested that we could add a little more freon to the system in the event there was a possible slow leak. Ultimately, he ended up adding freon to both the upstairs and main floor unit, and unexpectedly much more to the main floor unit. The price after the fact surprised me, especially given that particular unit had appeared to have been working fine; the tech told me it was possible that unit had a leak. He informed me Summit would schedule a leak investigation if desired, but that it would cost a whopping $1,100, so I declined given the performance on that unit had been fine. Fast forward a week or two, and the main floor is quite hot. The ducts seem to be blowing hot air. At which point it became clear to me the unit has actually stopped functioning. I call Summit, which is busy with appointments and express my dismay that the unit stopped working after the tuneup. They tell me it may be a leak etc., but they will send someone out. I wait for the scheduled appointment and the tech that arrives this time clearly didn't look over the prior notes or photos before arrival. I explain to him the situation, and he was confused about which unit was implicated, and claimed that the prior pressure readings from the earlier tech clearly indicated there was a leak (which was not at all what I was told). He later retracted this statement after realizing what time of day the earlier appointment was and said those pressure readings were normal. He poked around briefly, but without much investigation declared the system to have a leak, and indicated there was an 80% chance of it being non-repairable. He indicated they would have to do the $1,100 search to locate the leak, and if it was in the condenser/evaporative coils it would not be repairable. If it was somewhere else in the line, it could be, but then they would possibly have to tear into my walls, etc. to identify the issue. When I asked how much a new unit would be, he gave me a rough quote of $15,000, but told me that they would have to look at specs to price out more specifically. I asked him to do so, given I wanted to know what I was looking at, and he appeared inconvenienced by the request and said it would take him an hour. (It did not.) During that process, the tech told me my ductwork was not sufficient and I would need to downsize my unit, and that the smaller size wouldn't be enough to cool the floor. He suggested my unit may have broken because I keep the basement vents closed, but then he also claimed these A/C units only last about ten years. The whole visit felt performative, and ultimately was much more focused on theoretical salesmanship than anything diagnostic. I was left pretty frustrated. I called out a different repair company recommended by a friend, and within 5 minutes he had identified the leak and the location in the coil. Contrary to what I was told by Summit, this company informed me the coil could be replaced and that I had many more years of life left in the unit. Within the week, I got the whole thing repaired and refilled for ~$1,200--not much more than the cost of a Summit "leak search." While I've had positive and knowledgeable techs with Summit, this whole experience was such a breach of trust that I will not be using them again. I had another company inspect my furnaces this fall for a fraction of the cost, and I will not be looking back.

    WARNING- I hired this company to replace a hot surface…read moreignitor in my furnace. Previously, I've done this repair myself and it's a relatively quick and easy repair if you know how to watch YouTube. Unfortunately, we had a family issue which prevented me from handling it this time so we hired the first people who answered. One technician came and diagnosed the problem with a quote $851. I agreed. The next day, a different technician completed the job quickly and if you've ever done this job, it's plug and play and the most time consuming thing is unscrewing the panels. Total labor time across both visits was only about 40 minutes. Drive time, let's give them 2 hours. Unfortunately, the invoice showed just a single $851 charge with no breakdown. I assumed there was something a little more technical than an ignitor. When I questioned the bill, I was told the ignitor part alone was $200 or more. What does or more mean? Let's say a total of 2 hours of labor was involved and a $250 part. That's $300 per hour in labor! While I understand businesses have overhead and travel costs, this price felt surprisingly high for such a short repair and no transparency. Lesson learned

Shady company with terrible business practices.
