"My heat pump which had been installed 2 years ago by FH Furr suddenly stopped working Sunday afternoon. With the heat warnings in effect, I knew I needed help, FAST! Blair arrived this morning abd diagnosed the issue and replaced the condensation pump. These new "smart" systems have more brains than some humans!! When the pump failed, it shut down the entire system. However, Blair had the old school know-how and work ethic to get my system back online and back to normal. I have seen a nice change in technicians in the last 2 years and am always pleased to have them come out and fix any issues I may have. Keep up the good work!!"

"The project was completed seamlessly and Jim and his helpers were competent, hard-working and didn't mind explaining what was going on every step of the way! His years of experience are evident, and make him a great diagnostician and problem-solver. He even went out to buy stone to line the bottom of the trench dug outside of the house to insure that the new pipe would be stabilized underneath! There were a number of things that could have been complications (like tree roots, and breaks in the pipes going to the septic tank), but it was clear to me that Jim would be able to address them, if they did surface. This was the kind of thing that makes a homeowner very nervous, so I was so relieved that I had Jim do this work. Experienced, competent, honorable, and a really nice guy! So glad that I won't have to conduct searches for a plumber in the future!"

"Naturally, on the hottest weekend of the summer in 2019, with a houseful of guests for that weekend, the capacitor went. Normally, I'd order the part and fix it myself, but that would have taken days to acquire. Air Temp showed up first thing in the morning the following day, and quickly verified the broken part and replaced it. Sure, of course it was more than doing it myself--but that's not the point. They were timely, had the part in hand, and were extremely reasonable on the price. We use them for our annual AC and heater checkups as well and will continue to do so for the foreseeable future. I highly recommend the team."

Water Heaters FAQs, answered by experts

It’s important to find the type of water heater that fits your needs and budget. Depending on the type of water heater, size, brand, and the type of energy you use to heat the water, costs range from a few hundred dollars to several thousand. Some of the most common types of water heaters include:

  • Electric: $600–3,500

  • Gas: $700–$2,700

  • Propane: $700–$2,500

  • High efficiency: $1,500–$3,000

  • Indirect: $1,200–$3,500

  • Hybrid heat pump: $1,200–$3,500

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home. 

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.

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

Water heater installation code requirements are in place to keep your family and home safe. Water heaters that are installed wrong can simply not work. However, that's an, if you're lucky, type of situation. More commonly, incorrectly installed water heaters pose a real threat from carbon monoxide poisoning, gas leaks, water leaks, and even explosions. 

Any item that can hold on to moisture and encourage mold growth should be discarded and replaced following water damage. Upholstered items, such as armchairs and couches, and soft items, such as mattresses, usually must be thrown away once they've taken on a lot of water. Soft furniture is difficult to dry out, creating an inviting environment for mold.

You may also need to replace hardwood furniture following water damage if you're unable to fully dry it out. If you have appliances and electronics that have been fully submerged in water, particularly sewage, you'll need to replace those, too.
