Thermostat Installations and Replacements
Unlike earlier thermostat models, most modern thermostats do not run on batteries. They require specific wiring to power them and allow for safe interaction with your HVAC system. Our HVAC experts will replace your existing thermostat and make any necessary wiring upgrades. They will also inform you about which thermostats are compatible with your current HVAC system. That way, you’ll have your thermostat installed correctly on the first try.
Thermostat Repair Services
If your thermostat behaves strangely, count on Larry and Sons, Inc. to find out why. A surprising number of thermostat malfunctions stem from relatively minor problems. For example, dust accumulation inside your thermostat can obstruct its sensors. Alternatively, your thermostat may simply need recalibration to restore its functionality. Whatever the problem, we will offer a lasting thermostat repair to solve it.
Thermostat Upgrades and Energy Efficiency
One of the most compelling reasons to upgrade your thermostat is to improve the energy efficiency of your HVAC system. Our comfort experts install a Nest thermostat to modernize your home’s HVAC functionality. With it, you will experience greater comfort and save on energy costs. According to Nest, the average U.S. user saves up to 12% on heating bills and 15% on cooling bills.
Smart Thermostat Installation
Today’s best thermostats make older models seem primitive by comparison. They feature internet connectivity and a plethora of advanced features. For example, most smart thermostats incorporate sophisticated learning capabilities that enable them to make intelligent, automated temperature adjustments. Many also include geofencing abilities that detect when you arrive at and leave your home.

Thermostat Service FAQs
Homeowners ask us great questions about thermostats every day. Here are some of the most common questions and their answers.
What type of thermostat is best for my home?
There’s no one-size-fits-all thermostat. We recommend Nest smart thermostats because they provide quality and industry-leading features. However, if you prefer a conventional programmable thermostat, you can choose that as well. What matters is that your chosen thermostat offers the functionality you want and the comfort you need.
Can I install a smart thermostat with my current HVAC system?
Smart thermostats work with any HVAC system, but they often require an additional wire called a C-wire for power. Newer HVAC systems provide power via a C-wire, but older systems might not. The good news is that adapter kits are available to power smart thermostats in systems that lack C-wires.
Why isn't my thermostat responding or turning on the heat/AC?
Several common reasons may prevent your thermostat from activating your HVAC system. The most frequent cause is when someone inadvertently switches the thermostat to the wrong mode. For example, a thermostat set to heat mode won’t activate your AC, no matter how low you set the temperature. Another common issue is a tripped HVAC circuit breaker.
