Shopped around for new coil and condenser outside unit...Ato did a walk through came back with professional and explanation statement with a reasonable quote ...installation took place following week with his team did a good job and amazed on how they relocate the entire unit system up in the attic to have better access with maintenance without extra cost...Fantastic job Ato!!! Everything is running fine after three months installation and looking for your next inspection....trusting your work and great to see efficient and professional company.

I know who to call first when I have a HVAC issue. Stalwart Mechanical Services has helped me with residential and commercial HVAC repair and maintenance. They helped me find the best price, were on time, and professional yet friendly. I can't say enough good things about them.

Very professional, very knowledgeable, they go the extra mile. I would highly recommend! They are my air conditioner repair company for life. Mike and Walter are awesome. Thank you so much for your good service.

I would and have recommended Stalwart mechanical for your A/C or heating needs. When our unit went down it was Friday night, Ato came out the next day to diagnose the problem. We decided to replace the entire unit inside and out. Him and his crew installed everything on that Sunday and had us back up.and running. They were very meticulous on keeping the area clean in the house where they were walking back and forth. The small things like this is what impressed me and we have called him out since to add returns throughout the house.

They quoted me a competitive price for a new ac unit install. Once I gave them the ok they were at my house the next day and finished in 3 hrs. Very friendly receptionist and good techs. Thanks for the deal!

Very punctual and professional. I called John Moore and they tried to sell me a $6000 system to fix the problem. Called Stalwart and they diagnosed and fixed the issue for minimal cost.

Ato is a person you can trust. He tells you the honest truth about your situation and doesn't make up things just to get your service. He has been my A/C service guy for years and has always done a great job. My 15 year old unit finally meet its match and Ato got me a great deal on two new units. He and his crew came in in the morning and finished before the evening. My house cools much better now and it is more efficient. Last year my August Bill was $400.00 and after replacing the units this year my August Bill was $191.00 (3,800 s.f.house). They not only replaced my units and condenser coils but they corrected the ductwork that the previous A/C guy did at no extra charge. I highly recommend Mr Ato to anyone: I've already recommended him to my brother and other friends.

Lightning during Hurricane Harvey sent a power surge through my house killing both a/c units. Stalwart provided fair pricing and great service. I would recommend these guys to anyone. Most difficult part was dealing with my insurance company

They answered my call on the second ring on a Friday night! That already told me how professional these guys are. They showed up on time for the repair and were friendly to my family (during these times, that’s really saying something). Thanks so much, great work.

Got into trouble with faulty furnace during arctic blast power outage. Stalwart have been responsive, quickly arranged a personnel. Ato visited on time and diagnosed it promptly and answered all my questions. Got to heat uo home again. Will recommend.
