I WILL be calling Bell again and passing their number out like it was pez
“A/C unit pooped out, and was in complete distress. I called the after-hours line and got a call first thing in the morning. They had a tech at my house at 9am, and it was fixed within 30 minutes (the capacitor blew). Travis was exceedingly nice, explained the issue, and had cold air running in no time. Cost was beyond reasonable (and I've been gouged by other HVAC guys before). I WILL be calling Bell again, and passing their number out like it was pez (do you millennials even know what Pez is nowadays?). Heaps o' thanks, Bell!”Kevin P. -

I called Bell a/c to just do a checkup for my a/c before the heat starts. I was so impressed with the young man Stephen.
“He came in wearing a mask, booties and told me what to expect. He was so polite, knowledgeable, explained everything he was doing. I expected him to say that I needed a new unit (it is about 20 yrs. old) but he said it is working very well- needed nothing - not even Freon. Last year I used a different company and was told that I would need to replace the entire unit within a yr. which I didn't. I appreciated his honesty.”Leslie -
