Costs & your service visit

Pricing and what to expect.

How long does thermostat installation take?

Most thermostat installations take 30 to 60 minutes. If wiring upgrades or system calibration are required, the process may take slightly longer. A professional makes sure everything is correctly installed for optimal performance. 

How much does thermostat installation cost?

Costs vary based on the type of thermostat, installation complexity, and any necessary wiring upgrades. Smart thermostats may cost more but provide long-term savings through energy efficiency. We offer transparent pricing and financing options to fit your budget. 

How much does thermostat repair cost?

It depends on what’s going on with your thermostat. Sometimes HVAC thermostat repairs are a quick, inexpensive fix, and other times a replacement is the better option. Once we take a look, we’ll give you a clear price before any work starts.

Choosing the right option

Help deciding what makes sense for your home.

How do I know it’s time to replace my thermostat?

If your HVAC system is struggling to maintain the right temperature, cycles too often, or your thermostat is outdated, it may be time for a replacement. Signs like unresponsive controls, incorrect readings, and rising energy bills indicate your thermostat is no longer functioning efficiently. Upgrading to a newer model can improve comfort and energy savings.

Can I install a new thermostat, or do I need a professional?

While some thermostats are designed for DIY installation, improper wiring or calibration can cause HVAC malfunctions. With professional installation, your thermostat is set up for compatibility, safe wiring, and proper system integration. If you're unsure about your system's wiring, it’s best to hire an expert. 

What type of thermostat is best for my home?

Choosing the right thermostat depends on your system and preferences. Smart thermostats offer automation and energy tracking, programmable models let you set daily schedules, and basic digital thermostats provide manual control. Our team can help you choose the best option based on your HVAC system and budget.

Good to know

More answers from our team.

What are the benefits of installing a smart thermostat?

A smart thermostat helps lower energy costs by learning your schedule and adjusting temperatures automatically. It allows remote control via a mobile app, integrates with smart home systems, and provides maintenance alerts. Upgrading to a smart thermostat can reduce energy waste and improve home efficiency. 

Will a smart thermostat work with my existing HVAC system?

Most modern thermostats are compatible with standard HVAC systems, but some require a C-wire for power. Compatibility depends on your system type, voltage, and connectivity needs. If your home lacks the necessary wiring, we can take care of the installation. 

Do smart thermostats save money?

A properly installed programmable or smart thermostat helps lower energy bills by optimizing your heating and cooling schedule. Smart thermostats learn your habits and adjust automatically, reducing energy waste and cutting costs by up to 20% annually. 

What should I do with my old thermostat?

Many older thermostats contain mercury and should not be thrown in the trash. We can help safely dispose of your old thermostat or guide you to local hazardous waste disposal services. 

Can I control my thermostat from my phone?

Yes! Smart thermostats allow remote temperature adjustments, scheduling, and maintenance alerts via a mobile app, making it easier to manage home comfort on the go.

Does thermostat installation require rewiring?

Not always, but some modern thermostats require a C-wire for continuous power. If your home has outdated wiring, our technicians can upgrade it so your new thermostat operates efficiently. 

Can you program any brand of smart thermostat?

Yes. Whether you’ve got a Nest, Ecobee, Honeywell, or another brand, we’ve worked with them all. Our goal is to make sure it’s set up correctly and running smoothly with your HVAC system.
