As a veteran-owned local company serving the area since 2008, we’re known for dependable work, fair pricing, and honest recommendations.

Common Thermostat Issues We Handle
Whether you're using a traditional programmable unit or a newer smart model, we’ve seen how small problems can lead to bigger system concerns. Inconsistent temperatures, rising energy bills, or a system that won’t turn on often lead back to the thermostat.
We work on:
- Blank or unresponsive displays
- Incorrect temperature readings
- Systems that short cycle or don’t run at all
- Wiring issues or disconnects
- Upgrades from old dial models to digital or smart thermostats
Sometimes the fix is as simple as recalibration. Other times, replacing the unit may be the better move, especially if your thermostat no longer communicates correctly with your system.
Helping You Choose the Right Thermostat
If you're looking to upgrade, there’s no shortage of options out there. From Wi-Fi-enabled models to learning thermostats that adjust based on your habits, we’ll help you compare features that make sense for your lifestyle or your building's needs.
We walk you through choices like:
- Programmable vs. smart models. Whether you want a consistent schedule or remote control via your phone.
- Zoned system compatibility. Especially important in larger homes or commercial buildings.
- Humidity and fan controls. Some models offer extra support for Florida’s climate.
- Energy reporting features. Helpful for keeping an eye on usage trends.
We’ve installed and serviced thermostats in everything from small Largo homes to larger retail and office buildings in Clearwater, Pinellas Park, and beyond.

Installation & Integration with Your Current HVAC System

If you’re already planning an AC or furnace upgrade, we can include thermostat installation as part of the broader service.
And because we handle a full range of heating and cooling services, including heat pumps, ductless systems, and air quality upgrades, you don’t need to coordinate with multiple contractors. One call gets it moving.
