Recommended Customer Reviews

Esmerelda, their plumber, was fantastic, knowledgeable and pleasant, and got my kitchen sink unclogged and running like a champ. I would definitely recommend, particularly ask for Esmerelda, a great example of women in the plumbing profession.

Hayes mechanical charged $830.30 to change a filter because ""they didn't have a proper ladder"" and took 4 hours to retrieve one. They purposely took over 3 hours just to get a ladder and then charged for those 3 hours as overtime plus the regular hour it took for them to change an air filter. As a mechanical company that specializes in heating and air conditioning as they advertised, they should have came prepared with a proper ladder. Especially, if they had come to this location previously, as we had a contract with them. An air filter change should be as outrageous as $150. Just to come and take a look at it shouldn't cost an extra $700.00 for them forgetting their ladder and arriving extremely late. I would like to write this review so it can report their improper misconduct so no one else gets charged $830.30 for arriving late, forgetting their ladder, and changing an air filter.

They came out 3 times to my apartment for a hot water plumbing issue in one of my showers. After 3 visits and 3 different plumbers, I have now been charged 3 times and spent half a day at a plumbing store buying parts that the third guy decided we didn't actually need... and still not fixed. DO NOT USE THEM. horrible customer service and still haven't fixed the problem.

Absolute scam of a company. They will be in your home for 5 minutes and Bill you for 5 hours. Beware!!!

Prepare to open your wallet, bend over, and be completely dissatisfied with their work, the level of honesty & integrity they have, and their level of professionalism. Avoid at all costs.

I need to get my fireplace working from a wood to a ventless. Our building manager suggested them since they work with the building. I got a quote of $800 from them to hook up and install the valve. Instead, they charged me $1100 and NOTHING was done! They charge me 6 hrs of work, parts and the use of their van?! That included 2 hrs of estimate that only took 15mins, which should be free! They started to find the parts but didn't, so what part did they used? Nothing was installed. I had to hire another guy to drill a hole on the floor get find the value. That cost me another $300. I mean NO WORK.

We hired Hayes Mechanical to service our outdoor heater and were charged a whopping $3500 and it was still not operating. Now they are suing us for payment. We had to hire another company to fix it and they fixed it for $308. If I could give them 0 stars, I would. They are thieves.

Used them for some renovation work and was quoted more than other quotes I got because of past work they've done. Turns out I was misquoted and they charged me another bill after the initial quote. Very unprofessional and poor workmanship since they changed their management team.

I have had the opportunity to work with Hayes Mechanical to complete work on a number of energy related projects. They bring a high level of expertise and helped us save energy and money.

Hayes Mechanical was the winning bidder on a mechanical preventative maintenance contract for several schools at which I work. They respond to our service calls very quickly and quote reasonable prices on work. They also make sure to have the same service technician work at each school when possible, so the technician can build a working knowledge of how the systems function and historical issues each system has experienced. We love working with Hayes.
