Walter and his partner did an excellent job. Installed a brand new evap coil and plenum chamber. Very competitive pricing and great quality workmanship. He explained everything in detail and was very clean and tidy. Definitely will be using Walter and Stalwart again. Full review ›

Walter was very efficient and reliable. I had received 3 quotes from other a/c companies that were inflated. Stalwart provided the best quote so I was able to get a better unit at a fair price. They paid attention to detail, were on time and after installing unit, they did a thorough clean up. I highly recommend Walter and Stalwart Mechanical. Full review ›

Terrific job! I couldn't be happier. This is the third time I've used these people, and it always seems the same, excellent. They show up when they say they will, and today the office called to tell us they were running a bit late (about 10 minutes). Full review ›

I searched yelp for a good recommendation for a heater repair and came across Stalwart. I asked my husband to call and Walter came out. My husband was impressed with the hard work and great job that Walter did. We have always had a hard time with A/C- Heater repairs because there's hardly any honest, hard working techs that take pride in their job.... Full review ›

This process was far less painful than I expected. The service is friendly, straightforward, and honest. I will be setting up a time for repairs in the near future. Stalwart... Full review ›

AC went out on Thanksgiving. We had two companies come out and had us thinking we needed to replace our unit. My husband found this company with 5 stars and gave them a call. Walter came out, worked in the dark, and quickly identify the issue which did not include replacing the unit. After thoroughly inspecting the unit, Walter replace the part... Full review ›

This company is unbelievable!
They came out to fix another companies "mess up". Oh my goodness did they come thru!
Walter, did an exceptional job in taking over and making us very happy and satisfied.

Try them out! You won't be disappointed! Full review ›

These people helped us install an AC as ours broke on our way out the door to a family emergency in another state. Even though we weren't home they helped us over the phone and everything was finished when we came back. They even worked on a Saturday because we had a small infant whom we wanted to keep out of the heat.

They were the third... Full review ›
