Heat Pump Water Heater Installation

What Is a Heat Pump Water Heater?

A heat pump water heater uses heat pump technology to heat your home’s water far more efficiently than traditional gas or electric water heaters. Instead of generating heat directly, it pulls heat from the surrounding air and transfers it into the water tank, using significantly less energy in the process.

Because they rely on heat transfer—not combustion—heat pump water heaters are among the most energy-efficient water heating options available today.

What Your Neighbors Are Saying About Us

Alison K.
Aaron came out to service my AC unit. He was prompt courteous and knowledgeable and did not try upselling which I appreciate. I like that this company sends photos of their technician ahead of the visit and ask for feedback on their performance. They are very customer centered. I also get great courteous service whenever I need to call and schedule with them. Highly recommend!
Sam S.
This was the most pleasant installation I’ve ever been part of. There was no attempt to upsell. Had a great conversation about what we needed, we set a date they were prompt, clean, and so professional. Did the job explain to us everything they did. I would use them seven days a week and twice on Sunday! Highly recommend!
Eric S.
These folks are the best HVAC company I think that I have ever worked with. Everyone and I mean everyone was wonderful! From Aaron who did a fantastic job assessing the system and getting the replacement mapped out, to Preston and Phaylan who did an amazing job with the install, to Lisa in the office who kept me informed and supported throughout the whole process. They are cost effective, super friendly and extremely high quality. I cannot thank them enough for a stellar job! Truly elite level service at a very accessible price. A++ all around!
Mike McD.
STRONGLY RECOMMEND! What a great experience. Chris McCollum was the technician that came out and identified the issue very quickly. I am always wary of these kinds of services and being upsold on solutions. He fixed the issue and gave me some options for preventative measures we could take to make the system last longer, but didn't push for any of them to be done immediately. Which weirdly made me more receptive to having some of these scheduled to be done soon.
Mary R.
Thank goodness for Southwest Heating and Cooling! They were so helpful on the phone when I called in to say that my thermostat seemed to be dead. Jeremiah was able to diagnose the problem, gave me a couple of options for the fix, and got everything taken care of right away. He was professional, explained everything to me, made sure all my questions were answered. Highly recommend.
Marie McG.
This was the second time that I have had Southwest Heating and Air Conditioning upgrade my HVAC system and they did another excellent job. Jeremiah installed a new steam humidifier in my home and was professional, knowledgeable, and conscientious. He stepped me through the process and answered all my questions. I would highly recommend the company and Jeremiah.
Julie G.
I am so pleased with the work that has been done by Southwest Plumbing and Heating. The owner personally came out to give me a quote. The staff and installers were very professional and extremely friendly. Anyone is welcome to call me to talk about it.
