He said he'd be here between 4-6pm and showed up at 3:45pm. He came in and diagnosed the problem, which all made sense, made the repair and even fixed a light that was not working. He did a great job and it only took about 30 minutes. Very nice and very knowledgeable about all things appliances. I'd highly recommend him!!

I am completely blown away with the quick and professional service from Thomas! On my way home from…read morework, I received a call from my hubby of those dreaded words on a 100 degree day.. "the AC went out.." I drove home pretty much in tears, preparing for the worst.. either several days and nights of being super uncomfortable to be blasted with a huge repair bill or the news of the need of a whole new unit. Quite the opposite to my surprise. Thomas arrived at our home in less than an hour of our service call, quickly diagnosed the problem, had parts on hand, and within 15 minutes, we were cooling the house again. No joke, no run around, no sales pitch, no highway robbery. Just a true expert providing the service we needed to get us going. The cost? So insanely reasonable in my opinion. We will for SURE be a returning customer with several appliances issues we've gathered and not fixed along the years. Thank you for helping restore our faith in getting the problem fixed, with a smile and sense of urgency, with no unnecessary charges or taking advantage of the customer. A++++++.

We are on the "do not mail" list and as a result hardly get any junk mail which is nice. When we do…read moreget something from a company, I email them, they apologize and remove us. The only others are the real estate scammers and those people play by their own rules (which is why their yelp reviews are awful). Then there's this place. Sending junk mail to my house - I emailed and them and started off with "we're on the do not mail list" - their junk mail is addressed to us (not resident) to our address meaning they got our name off some list and are sending this to us. His response was "you should sign up for the do not mail list (completely ignoring the first sentence of my email) and you have to pay a fee - also contact your local post office." Refuses to remove us from his junk mail list - and is telling me to sign up for the list I told him I was already on ("and you'll have to pay a fee!" - yeah, I paid the fee so scammers like you wouldn't send junk to my house) and telling me to contact my local post office. What does contacting my local post office do? They will tell me to contact these shysters to get off their list. I gave this guy every chance to remove us and just kept repeating "contact the do not mail list." So let's be clear - these people think if they keep sending their junk mail to our house, we'll give in and use their "service." This is as unethical as it gets. There are tons of great plumbing and heating services out there folks. An honest company says "let's get you off our list ASAP." A dishonest company ignores your email and tells you to contact the post office. It's such a simple thing to do, yet they won't. But don't take it from me - read the other reviews here. Not a good sign, is it? I love yelp and the good it does informing customers. Now the guy is going to respond and tell me what a bad person I am or how great his company is or some lame response. Again, just read the other reviews here - tells you all you need to know.

Sure, some parts are a little pricey... but, I am completely amazed their WILLINGNESS to help: Whether it's searching for OEM parts (for MOST models, Carrier, Goodman, Rheem, Lennox, Payne, Trane, Bryant and more...) or offering lower priced & comparable after market replacements; Whether it's delivering the parts to you, placing Will-Call orders for you at other locations, or, showing integrity by directing you to their competitor's store if they know that that vendor can help you out by getting the rare part which they may not be able to... They are a class act!!!! So, go see the Owner or my Man "Joey" and get the kind of respect and service all customers want (and most deserve). Be safe out there!

Then they RANDOMLY showed up at my door on (I forget, thurs or Friday the 1st/2nd) and just said "hey can we do it on Sunday" lol talk about on the spot. Was my anniversary weekend so I asked if I could schedule for Tuesday (mon being Labor Day) he just kinda stared at me but never scheduled me with anything. So I called on the 6th, left vm, no reply for over 24hrs, called today, no answer, finally texted and got a reply that just kinda brushed me off that they're "booked" through the weekend. They didn't really give a shit about scheduling an appointment it's like they want to just show up when it's convenient for them. Very strange way to run a business. Would not use them for any services.
