"I called Hosack on a Thursday morning because my water heater had died, and because of their great Angi reviews. They had a plumber, Kent, at my house before noon. Kent was fantastic ... great work, extremely knowledgeable, and VERY customer oriented. I'm extremely happy with Hosack's responsiveness, quality of work and attention to detail. Going forward, they (and I hope Kent!) are my plumbers of choice. I highly recommend!"

"JT Dunn Climate Control won my business by being honest and letting me know what would be in my best interest on the maintenance of two HVAC systems in an industrial building of mine. They were very thorough and saved me a lot of money. Then as part of a renovation project they removed two older systems and replaced them with one, installed four new gas infrared heaters on the dock, repaired an old heater, removed other old equipment, and repaired ductwork. They were excellent in every way. They are reliable and trustworthy. They are definitely going to maintain my systems going forward. And they are now the first HVAC company on my list for any project. Next, I'm going to ask them to quote the replacement of my 18-year-old home HVAC system."

"My hot water heater went out. I called several plumbers and was being quoted astronomical amounts along with quite a wait time to get to me. Brice was able to get the job done quickly (since no hot water sucks) and at a price I could live with. He was super funny and professional and made me feel like a friend had come over to help. I will always call him first for any of my plumbing needs"

Water Heaters questions, answered by experts

The average water heater holds between 40 and 60 gallons, but the exact amount of water that comes out during draining will depend on your unit’s capacity. The amount of time it takes to drain a water heater averages from 10 to 30 minutes.

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.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

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.

Yes, a heat pump water heater can work in colder climates but it’s much more effective where it’s warm. The reason is that the heat pump needs ambient warmth in the air to compress. The less warmth, the more compression required, thus using more electricity and offsetting the energy-efficient benefits.
