STAY AWAY FROM THIS FIRM.... I purchased a hot water heater from Home Depot which uses Delta Mechanical to install these heaters if the customer asks. The installation ""failed"" the required inspection by the city. I called and scheduled (I thought) someone from Mechanical to come and make the necessary corrections in order to pass the inspection. The repairman was a ""no-show"". I called Mechanical once again and was told that someone would contact me that evening or first thing the following morning. No one called..Once again, I called and was told that there had been an error on their part in scheduling the work and the earliest they could get someone was Friday 4-6 pm. I asked for something earlier and was informed that this was not an emergency and that was the earliest available. So new business has priority over correcting their unsatisfactory work. There are less expensive firms around that do good work. My mistake is I thought that if they were affiliated with home Depot they would d quality work and provide excellent customer service.I was wrong-my experience with them has been totally unsatisfactory.

Mitsubishi split system install. The install was done in a timely manner, the techs were competent and polite. Looks great feels great. I didn't like where the condenser was. I called Alex the manager, he came and said, we can fix it however you want"" ! That's good customer relations. Only thing was they didn't call when to inform they may be late. But once I mentioned this, it never happened again. Happy now.

Horrible company! Contracted through Home Depot. Took almost a month after purchasing high efficiency toilets for the company to schedule an install. Hours later one of the toilets began to leak. After mutiple calls to get the tech back to the house, we were given a window way later in the day and they never showed!

Pro tip: Don't be like me and read the bad reviews thinking ""But that won't happen to us!""

Our water heater died a horrible death and I looked up water heater installation through the Home Depot website. I spoke to a rep at Delta Mechanical just after 11:30am and made an appointment for a same-day installation between 4:00-6:00pm. I had an itemized list of what the installation included, a final price, and gave my credit card number and info. The rep was so friendly and helpful that even though I read the horrible reviews on here, I thought maybe they'd made some changes and things were better. Wrong doesn't even begin to describe it.

6:00pm rolled around and no one had showed up or called, so I gave it until 6:15pm and called. My call was received by an answering service, and she said she would have someone get in contact with me. When I still hadn't heard back at 6:35pm, I called again. This time I was told that my information was sent marked as urgent and someone would get back to me. Nothing. So, without a water heater and no plan for getting one installed, we went to Home Depot to buy one and do it ourselves. While we were there, two Home Depot employees who were helping us both mentioned that they contract with Delta Mechanical to do installations and that ""it's a great deal"" and I ""could have them do it tomorrow!"" When I explained our situation and the reason for our nighttime trip to Home Depot for a water heater, they encouraged me to chat with a customer service rep at the store that handles installation appointments.

He not only acknowledged how crappy the situation was, he said that these no-shows have been a trend with Delta and that he's had THREE customers recently experience the same thing! It took him well over 30 minutes on the phone to talk to an actual person, and because he was a Home Depot employee, the answering service for Delta was able to put him in contact with an actual customer service rep. He explained the situation and told them it was an emergency install because we had no water heater, and they assured him someone would be in contact with me that night.

In the end, we stayed up until 2:00am installing the water heater ourselves and never heard a peep from anyone at Delta Mechanical. However, I did just receive a call at 10:30am from someone at Delta Mechanical confirming my appointment for today (?). I explained to her that we do not have an appointment for today and will not be needing an appointment since we took care of it ourselves, and she said, ""Oh, I can see your messages from yesterday here. I guess the rep that looked at them this morning disregarded them because you were on the schedule for today."" I'm sorry, but WTF? If my appointment was scheduled for today, why would I be sending urgent and emergent messages last night?

I understand that clerical errors happen. I can understand that things get busy and our appointment could have been accidentally scheduled for today instead of yesterday. But I have no interest in working with a company so utterly lacking in customer service that they not only disregard urgent calls from both the customer and Home Depot, they continue to disregard them during their normal business hours the following day. Major fail all around.

We had mini split heating and AC installed by By Delta, an affiliate for Home Depot.
Couldnt be happier. Great follow up service by Serge Padrino. Serge took to the time to explain the system and made sure that everything was working properly.
Thank you Serge, Thank you Delta. Thank you Home Depot for the no interest loan.

I had a kitchen sink installation arranged through Home Depot. Jessie was on time and efficient. When sink clips were missing from the box, Delta Mechanical came back out to install them. Each time Jessie arrived when scheduled and thoroughly completed the work.

Worst company ever. I wish we had read the reviews before going through Home Depot for a water heater. Thankfully our water heater was only leaking, so we had time to get another company.

Our water heater was leaking, so we thought going through HD was a safe way to get the work done. We called the wed before New Years and asked for the work to be done on Monday. On Monday morning Delta called and said the tech called in sick, so they would not be doing the work till Tuesday. On Tuesday they show up and see that our water heater is under the house in a crawl space (the space is large enough to stand and walk around in). The tech immediately gets an attitude and says it's a 2 man job, and our response was we told HD that it might require 2 people. The tech then looks at the area and says there is no way drain the tank. He then goes outside and calls the office saying he can't do the job. The office calls and tells us they will not do the work. The tech then comes to the door and says he won't do the work, then says ""don't worry we won't charge you for the visit"" . My wife promptly slammed the door.

We then called Courtesy Plumbing who came out the next day and did the work. It one person 2 hours to drain and remove the old tank, and install the new one. This company is the WORST.

Awful service!!!! Arranged for faucet install though Home Depot. Home Depot told me Delta would contact me within 2 days. They did not. After being on hold for 30 min. after I called them, we arranged a 2 hour window for install. 45 minutes before this window, they called me to tell me they couldn't make it. Arranged for another 2 hour window on a different day. After this window expired, never heard from them, I called and was a on hold for a full thirty minutes, the rep said she couldn't get ahold of the installer. 20 minutes later she called and said his truck had broken and he couldn't do it. When I asked if I could have a specific time, not a window, for the next attempt, I was told not. I will not use!!! Very, very poor service, do not use!!!

When you invite a service provider into your home it's risky business. You never know the kind of technician you'll get or the quality of the service. Over my many years... I've had the worst... I've had good... and today I've had the best. Serge Pardinas came to inspect and work on my heating and air-conditioning unit. He was scheduled for between noon to 2pm. I got a call from the Delta Rep asking if he could come at 11:30am... that never happens. As he worked on the unit, I had questions. He took the time to explain things, make recommendations and didn't try to sell me things I didn't need. My H/A system runs better than ever!!!! For such a young guy, Serge has a unique perspective on what great customer service looks like. It's a perspective that usually comes with age, training, seminars and lots of practice. He was kind, patient, professional, knowledgeable, great communication and did I mention.... kind. He was never condescending or put off by my questions. Gave me good advice for taking care of my system. He only sold me the part that I needed and didn't try to upsell like some others do. From this point on Serge is my go-to-guy for all things heating and air-conditioning related. Here's the kicker.... my dog liked him.

Purchased AC unit through Home Depot, was told that they would be here on Wednesday, they promised Thirsday, cancelled and rescheduled for Friday, left us waiting at home for 5hours without notification, and rescheduled for Tuesday. Beware if you work! Now I'm out 4 days of work. Terrible customer service. Home Depot really should choose a more reliable company.
