Tom H Davis Plumbing & Heating | Qualified HVAC Repair in Center, CO

A comprehensive plumbing inspection checks your entire water and drainage system. In homes with heat pumps, issues like a clogged condensate drain line—which we identify during the inspection—can cause the system to shut off as a safety measure. By clearing this and ensuring proper drainage, we can often resolve the underlying issue causing your heat pump to malfunction, especially when related to moisture or pressure problems.

While the thermostat itself may need calibration, it's a good question. In some homes, especially with hydronic (hot water) heating systems, a plumbing issue like a clogged zone valve or a failing circulator pump can prevent hot water from reaching certain radiators or baseboards. This makes it seem like the thermostat is faulty because the room never reaches the set temperature. Our plumbing inspection can identify these hidden hydraulic issues that mimic thermostat problems.

The most common first sign is that your heat pump seems 'stuck' in one mode. For example, it only blows cool air when you've set it to heat, or vice versa. You might also hear a noticeable hissing or gurgling noise from the outdoor unit. This valve is crucial for switching between heating and cooling. If you notice this, it's best to call for service promptly, as running it with a faulty valve can cause further damage to the compressor.
