Our AC went out a little over a week ago, of course it happened toward the end of the week so it…read morewas Friday afternoon by the time we realized it wasn't something routine maintenance on our side would fix. Jary (who helped us when we first moved in) came out on Tuesday and said we had a leak somewhere since the closed-system unit was totally out of coolant. He came back Weds. to do the leak detection and found the leak, recommended a new coil. We had the new coil installed on Friday; this time it was Ricardo and team that did the work installing the coil. They did a great job and a couple hours later our house was back to normal temperature. Gabriel helped us with all the coordination and estimates and seeing if the part was still under warranty (it wasn't, but I didn't expect it would be honestly.) No one likes spending a bunch of money on repairs but I'm very confident that the recommendations Jary made were sound and correct. He did not attempt to upsell me at all, which is greatly appreciated. (The estimates Gabriel sent did include options for replacing the unit, but that wasn't necessary at this time and there was no pressure to do so.) I will continue to call them if we have issues in future with our HVAC system.

I explained that while I am no expert, there being a steady drip of water coming from my AC onto the basement floor seemed to be a problem. The woman helping me offered up that perhaps I should check my filters, but we could go ahead and schedule an appointment anyway, which could be cancelled if that was all it was. It's summer and I expected them to be backed up with calls. I was given the option to have a visit the following Wednesday, or someone could come by on Saturday morning first thing, though it would be at the emergency rate. I went with the latter. Ivan showed up Saturday morning, introduced himself and had the clog issue figured out within minutes. He explained what he was going to do to take care of it, and got to work. When done, he let me know other issues needed to be addressed, but it would be less costly if I scheduled those outside of this visit and also weren't necessary to fix the issue I had originally called about. He explained point by point what else they would do if I decided to set up the additional appointment, how long it would take, and the price. I paid my bill with Ivan, and was sent an electronic receipt with the plan. Ivan departed and the leak was fixed. All is well. Fantastic service.

Environmental Systems Associates replaced my furnace, air conditioner, and water heater years ago…read more I was happy with the work and equipment, and I thought the price was fair for quality work. A friend is convinced that I overpaid, but ESA was comparable to other quotes I was given. Recently, I smelled gas by my water heater - I had to be very close to smell it. Some people online say this is common, but I didn't want to take the risk, so I had ESA come out to check. They told me it was an issue, replaced the "bad" part they identified, and charged me $945. The new part also smelled like gas. I reached out to the manufacturer, Bradford White, and found that this is normal. I reached out to ESA to discuss their mistaken diagnosis and unnecessary replacement.. I called three times and sent three emails, but the only response I got was "someone will call this afternoon." Nobody called that afternoon or any other. In the end I had to issue a chargeback through my credit card company. I do not plan to work with ESA in the future. Edit: I've reached out, per the comment below.

I have tried reaching out multiple ways, including email, Yelp message, phone call, voicemail, and text message, but have not received a response. I understand companies get busy, but when a recently installed HVAC system has an issue, I would expect some level of follow-up, especially if warranty service may be involved. Based on my experience, I am disappointed with the lack of communication after the installation. The initial work may have been completed, but the lack of response when a problem came up has made it difficult to recommend them.

The whole job, including removal and disposal of the old unit, shouldn't take more than four hours for two guys. The list price of a new unit delivered with state taxes was $1600. I was about to say yes and then... Two DAYS after that conversation, The $3100 number I got over the phone became $4250 in the official quote. No itemization. No explanation.
