Turns out I just needed some triple A batteries 😄. These guys have always gone all out for my HVAC system. In the last couple of months I must have met six or seven techs. The system is old but we've found the problem.

Tech was respectful of my property and of me, wearing appropriate PPE and social distancing. He explained everything and followed up with a detailed report. No high pressure. I will certainly recommend them to others.
Update: McCullough just installed an entirely new system for me. They arrived shortly after I called and brought a window unit for my bedroom to use until my system was in. Had done my research and Alex suggested exactly what my research indicated I needed. The installation was scheduled for the next morning, Saturday, and the installers followed safety protocols. So grateful for them going all out to help me. They were exceptional and I recommend them highly and in fact already have.
Update: Thomas installed my new thermostat as scheduled and made sure all was functioning properly before he left. Still recommending them to family and friends.
Update: Jaiden did a great job. He was prompt, respectful of my home and provided me with a detailed report of his work and findings.

Jaiden called in advance, arrived on time, did a very thorough job even though he’d had a long day, and wrote up a great summary. Very pleased!
