I'm just delighted with this company. I have a generator…read morethat dates back to 2007, so when I was informed by the installing company that it had bitten the dust I hardly questioned the verdict - it was 18 years old! Today Mr. Hoffman from Gen-Tech came to do an estimate for a new generator. When he saw that I have a generator he advised me it was possible it could be repaired rather than replaced. He then diagnosed the problem, replaced the faulty part, and ran a test to demonstrate that the generator does work! So now I have a working generator again, and at a fraction of the price it would have cost to replace it with a new one! Many thanks to the company, and they will have my business in the future.

Mind you they charge you $85 including tax just to receive your overpriced quote. Send me my money back and I will gladly remove my review. But anyways, in terms of your "warranty" it was clearly stated on the estimate that labor and installation were not included. And in response to "customer provided her own materials" that is because I was told multiple, multiple times that I had to because you didn't stock those items on the truck. Again, what you're doing is not good business, it is taking advantage of people who unfortunately do not know any better. I digress. Will completely price gouge you and charge obscene amounts of money and extra fees in their quotes. I would not recommend and not have them do any work. Save yourself THOUSANDS by having someone else do the work for you. Also nothing is warrantied including labor. A huge waste of time.

I recently built a house that uses Vastola Heating & Cooling as one of the subcontractors. I'm…read moreborderline impressed with the work that they did. I'll explain... The duct work is pretty clean looking and streamlined. With my house being a new build, I suppose you'd expect that the temperature would be comfortable with little wasted energy, but in many respects this is a testament to the quality furnace and duct work Vastola did install. Moreover, the humidifier does a bang up job as well. I'm was a little disappointed about a service call I had to make after we moved in. Our dryer is vented from the laundry room on the second floor to the side of the house, not the roof. Therefore, Vastola ran the vent across the joists of the attic floor. When I finally had a chance to get into the attic to store some things, I noticed the overwhelming smell of dryer exhaust. I checked out the vent and noticed it had come unattached from the outside wall. We called Vastola about the issue, and they came out to fix it, however, they were really defensive when they did so, almost as if they were accusing us of deliberately sabotaging our own dryer vent, which of course is ridiculous. I love dryer vents and would never do anything to harm one of them.

They quoted me $7000+ for a new A/C. When I asked for a quote to just replace they fan motor, they said they would get back to me. It seemed crazy to replace the whole A/C when there was nothing wrong with the coolant line or compression. Didn't hear anything so reached out a week later. They said they couldn't get the part. That my A/C mount was different and requited a special size. Bullshit. I went to S-S Electrical (on Seneca St), bought an A/C fan motor with the same specs as my old one, and changed it out myself for $200. Problem solved.

I built a house 4 years ago. Greg Schall did my heating and cooling. Greg was a great guy - professional, clean, organized. When my central air was not working all of a sudden, I gave him a call. He told me he retired a couple years ago and sold his company to a wonderful guy named William Young. Greg gave me his number to contact him. Upon contacting him, I got a call back from Bill (I believe) saying he'd get a service guy on it to call me and come out the next day. I got a call that evening from a Lenny or Larry saying he'd try to come out that evening but likely the following day. The following day I got a call from a different service rep Tyler. Tyler said he'd come by between 2-4. Tyler arrived that afternoon and proceeded to look at my thermostat. At first he thought I might need a new one. Then he proceeded to the furnace. He opened up the panel and looked around. He then proceeded outside to the 2 air conditioning units (I have one for my unit and one for my tenants). Long story short, he looked at both and said they were rusted and both needed needed new capacitors, new connectors and contactors. I was asking a lot of questions along the way and of course asked him about warranty and why after only a few years there is a problem with these. He asked if I covered them, I told him no. He said that's good because sometimes covering them can trap moisture. Then he asked if I was using chemicals near them, I said no. Basically he then concluded it was bad luck. I let him be to look at he furnace again and he called me when he was done. Said he was going to check with his boss about my warranty info and he was going to give me a discount of 20% off for today. I told him that although that's appreciated, NOT ONE OF THE 3 men I spoke with mentioned anything about a fee to provide an estimate. He said it was a diagnosis fee. I told him he'd have to invoice me because I was not prepared to pay him at that time. His boss proceeded to call me shortly after. Tyler told him I was upset and I told him I can't fathom why none of them mentioned their fee. He said it's COD and it's $80 per half hour. I said, "Isn't that something you inform your customers about prior to coming out?" He did not respond to that. He told me he'd look into any warranty and call me back. He never did. I know this is long but it gets better. I had someone else from another company come out to look at it same day. He was appalled at what he saw. Tyler put the disconnecter (on/off key on side of house) in for one of the units (mine) upside down. He also left the panel off the furnace (mine) which acts like a key to turn it on. He also left a wire/connector detached from one of the units (my tenants). By him doing all these things, neither unit would have ever even kicked on. I felt taken advantage of as a woman that doesn't know much of anything about air conditioners/central air units. He did not leave MY PROPERTY the way he found it. With all of these errors, I STRONGLY BELIEVE he did this on purpose so I'd have to ensure they come back to fix things. When the other guy finished up, all he had to do was replace 2 metal pieces (I think those are the contactors) on the ends of 2 wires and replace 1 wire. This company is completely unprofessional in inappropriate on how they handle customers. Not to mention they were basically given customers simply by the sale of the other company. I would not recommend.
