From Unresponsive Thermostat to Cycling Heat — Two Problems, One Trusted HVAC Pro
When your home's heating and cooling system acts up, the last thing you want is to wait days for a diagnosis or spend hours explaining the problem over the phone. At D&D HVAC Solutions, we pride ourselves on getting to the root of HVAC issues quickly, communicating clearly with homeowners, and getting things working again — often faster than people expect.
A customer in Hyattsville, MD had two separate experiences with us, and we're proud to share how both went.
The First Call: An Unresponsive Thermostat
The first time Bria reached out to us, her thermostat had suddenly gone completely unresponsive. No display, no response to inputs — just a blank screen and no way to control her system. Understandably frustrating, especially heading into the warmer months.
When David arrived, he got straight to work. Within 10 minutes of being on-site, he had identified the culprit: a blown fuse. It's one of those issues that can look alarming from the outside but has a clear, fixable cause once you know where to look. David replaced the fuse, confirmed the thermostat was communicating properly with the system, and made sure everything was running before leaving.
But the job didn't end there. David followed up after the visit to make sure the fix held and that Bria wasn't experiencing any lingering issues. That kind of follow-through is something we consider part of the job, not an extra.
The Second Call: Heat Cycling Without Airflow
Several months later, Bria's heat started behaving strangely — cycling on and off but not actually blowing any air through the vents. It's a frustrating situation because the system seems like it's running, but the house isn't getting warm.
This time, David asked Bria to send over videos of both her indoor and outdoor units before he even made the trip. By reviewing the footage carefully, he was able to diagnose the problem remotely — saving time and allowing him to come prepared with exactly what was needed to complete the repair efficiently.
After the fix, airflow was restored and the system was circulating better than it had in a while.
What Bria Had to Say
"David was incredibly communicative and diagnosed the issue — a blown fuse — within just 10 minutes of arriving! He completed the repair quickly and even followed up afterward to ensure everything was running smoothly. --- Bria from Hyattsville, MD
Fast forward to today, my heat started cycling on and off without blowing any air. I reached out to David, who asked for videos of both my indoor and outdoor units.
