Thermostat Installation and Repair in Louisville

If you’ve never had a thermostat replaced, here’s what you can expect with our team:

Initial Call & Scheduling

Our office team will ask about your current setup and your needs. We’ll find the soonest available time—often same-day.

On-Site Assessment 

A licensed technician arrives on time, reviews your thermostat, inspects your HVAC system, and recommends the best replacement options.

Install & Calibration

We’ll remove the old unit, install your new thermostat, and test it thoroughly. We’ll also walk you through how to use it—especially if it’s a smart thermostat.

Follow-Up Support

Whether it’s a question later that night or an integration issue a week later, we’re just a phone call away.

Here’s what we typically see with customers who need a thermostat replacement:

• Their HVAC system won’t shut off or turn on at the right time.
• Their home feels too warm or too cold, even when the thermostat says otherwise.
• Their thermostat is 10+ years old, not programmable, or completely manual.
• They’ve noticed higher energy bills but aren’t sure why.
• Their current system is incompatible with smart home technology.

Even if you’re not sure what the issue is, we’re happy to evaluate your system and provide honest guidance—no upselling, no pressure.

Our Advantage Plan was designed to reward loyal customers who care about long-term system performance and cost savings. Members enjoy:

• Priority scheduling, even during peak seasons
