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.

I called Jump to fix a control Transformer and was pleased to get a same day appointment…read more Adam showed up on time and proceeded to diagnosis the issue. His expertise noticed a couple of installation errors , one of them was related to the control transformer. He was able to fix and completely remove the failing transformer and utilize the furness control panel instead, nice clean solution as the manufacture intended. The other installation error was causing condensation to not exit correctly and was leaking water that was rusting the front wall pan. I was unaware of this and was looking at having to replace a 4 year old furness if the rusting was to proceed or had already damaged the integrity of the wall. Adam checked the wall out and concluded that the heating element integrity was still good and the wall had not been compromised to the point of furness replacement. Without Adam's knowledge and skills I would be in a bad spot in the near future from the poor installation. I'm very pleased and happy with the outcome, thanks to Adam and do recommend JumpHVAC.

I replaced the control panel myself, but was still having issues. I wanted to find an independent, trustworthy contractor to avoid all the corporate HVAC companies that will price gouge you if given an opportunity. James was able to work me into his schedule quickly (lucky for me!). He arrived within the hour timeframe he quoted, and had the issue figured out quickly. He even went above and beyond and ensure the prior control board was broken. He showed me what was wrong and got my unit working again. The price was extremely fair for his time and experience. I wish I would've started by calling him. 100% will be using him for all my HVAC needs moving forward.

I signed up for 3 different times available for the contractor to come over and give me an estimate. After feeling like everything was going to be ok, I never heard from Delta; not an email, phone call, or visit. I called Delta and they offered no apology for not getting in contact with me. Instead of sending someone over the operator gave me a quote and it was pretty high; she then emailed those over to me. Given how high their quote was and how they ghosted me on coming out to quote the job I decided I would not be using them for my installation. Instead I'll be going with another company that is charging me almost $700 less; and they actually showed up to quote the job on time.

Leaking toilet problem. Delta guy came out at least twice. Leak continued. After second time, it…read moregot worse: When I sat on the toilet, the whole seat moved - sort of shook slightly (I am almost 80 years old, and I only weigh120 pounds - so no reason for it to move at all). Was up all night with the leak - putting towels around the base of the toilet to soak up the water so it wouldn't leak into the unit below mine. I had already paid $275 (in advance) for this disaster. Billing statement -Delta Mechanical, Mesa, AZ - for $275 says it was for a toilet install (I believe it was only for a repair - there was no new toilet installed). Finally, gave up that Delta was actually going to fix the leak so I contacted a totally different company to come out and fix it. I won't be using Delta EVER AGAIN. I asked for a refund on the payment as I had to pay the other company which actually did the work to end the leak. (Delta denied the refund). Can anyone explain why Home Depot in Denver refers you to Delta when you call them - I think it is a big mistake. I wish I had read more of the online reviews before I contacted them. Would have saved me the money spent (for bad work) and a couple of sleepless nights - plus the $275 down the drain (or, in this case) toilet!!!

Efficient Comfort was able to come the same day, diagnose the problem, and fix everything at a very reasonable price. The entire experience was smooth from start to finish. Their responsiveness, professionalism, and fair pricing really stood out. I highly recommend them to anyone looking for reliable HVAC service.
