About Stewart Heating & Air Conditioning

I wish there were 10 stars that I could give Jeff for his excellent, patient, professional, friendly, care! He called ahead, was on time, & got right to work. He asked about my needs & discussed options. He even told me one thing was actually still in good shape, & didn't need replacement! That shows sincerity & integrity, & I'm so-o-o grateful to find an honest employee & business. Jeff is a wonderful plumber (& individual), such an asset to the company. I am thankful he came to my rescue. I was recently flooded by a hot-water heater blowing its top, & have been a bit stressed about the possibility of any more water flowing through my house... Jeff checked all the pipes & connections throughout, putting my mind at rest. Thank you, Stewart Heating & Air, for employing such a great guy! I'll be sure to call on you again should the need arise.
