"Also known as 'Gee HVAC Services', which is the company I thought I hired. They had 5 reviews and had 4 stars so I was fine with that. I only noticed that it was Granty's Topline Services when we got our receipt. We called initially to get heating fixed in an extension room. After they came the heat in the whole rest of the house went out. That's when I checked the receipt and then realized that this is not the company I thought I hired. When I found them on Yelp I thought they were Gee HVAC Services. That's when I saw the 1 star reviews and realized we were scammed. We literally paid $600+ to have our heat broken in the entire house. On top of that, after we called to have him come back and fix it, the heat was on in the house, but 2 hours later there was smoke coming out of the boiler room and water was EVERYWHERE. He said it was because we needed to change the water valve, but this problem didn't happen until he came to break it. I am now in tears and it is going to be 9 degrees tomorrow night and I currently have Covid. This has been an absolute disaster. Edit: I came back to do an update since we finally got a legit HVAC person in to fix the mess Tony made. First of all, he didn't do a tune up. Or at least the guy who fixed this said it was the shoddiest work he's ever seen. Secondly, he almost killed us. He bypassed the controller and hooked up the boiler to the always on mode, so pretty soon there was steam coming out of our boiler room and it was chugging out boiling water. It eventually would have exploded. I am considering any legal action I can and will review on every single site I can to warn people to stay away. This man is a crook. Also, my husband told me when he was first here and was looking at the radiator in a different room he had water spewing everywhere. I didn't know this at the time because I was sick in bed with Covid and my husband didn't want to upset me. Absolute disaster. I was fooled by the other business name he 'works' under (really steals)."

"Nick gave me a quote, and wanted more than half of the money up front for removing my old bathtub. So I paid him that money. A week went by and Nick would say he was coming soon to complete work. Then, another week passed and Nick would stop responding to me completely. He took $300 from me and now I can’t get it back because he has blocked my phone number. I tried calling him on my friends phone and the call went through finally. I asked Nick if he was busy can could come complete work and he pretended his phone got disconnected. This is a 23 year old - not someone with 18 years of experience. Be careful…I learned the hard way."

Water Heaters questions, answered by experts

Storage, tankless, heat pumps, and solar water heaters each suit specific space constraints, usage needs, and efficiency preferences.

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

If you’re having problems with your hot water heater and it’s 10 to 15 years old—the typical life span of a gas hot water heater—you may want to consider replacing it rather than repairing it. Water heater replacement costs about $1,300 on average. If your water heater is younger than nine or 10 years, paying for repairs is most likely worth it. You can always have a plumber assess your fixture to see what it would cost to fix it and then decide if it’s more cost-effective in the long run to replace it.

The good news is that most home warranty plans cover hot water heaters, regardless of whether you have a tank or a tankless model. Your hot water heater should be covered by your home warranty because it's considered an essential home appliance.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
