TYPES OF THERMOSTATS WE INSTALL IN RESTON

Many older thermostats lack energy efficiency and advanced features that modern homeowners expect. Upgrading to a smart thermostat provides greater control, convenience, and cost savings even when you’re not home. If you’re considering an upgrade, Dave’s Heating and Air Conditioning is here to help. Here are some of the thermostat options we install in Reston and Herndon:

Programmable Thermostats

These thermostats allow precise temperature control by adjusting automatically throughout the day. You can schedule them to use less AC while you’re out and lower the heat at night for better sleep. With their enhanced functionality, they have largely replaced older manual thermostats.

NON-PROGRAMMABLE THERMOSTATS

For homeowners who prefer simplicity, we offer non-programmable thermostats that are easy to operate. With basic button controls, you can adjust the temperature as needed—no scheduling or advanced settings required.

WI-FI THERMOSTATS

Wi-Fi thermostats give you remote access to your home’s temperature settings through your smartphone. Connected via your home’s internet, these thermostats offer seamless control from anywhere and feature easy, intuitive programming. They are available for both Android and Apple devices.

Smart Thermostats

Smart thermostats integrate with home automation systems, including smart speakers, to enhance convenience. They learn your schedule and automatically adjust the temperature for maximum comfort and efficiency. Perfect for tech-savvy homeowners looking to reduce energy costs.

Easy-to-See Thermostats

For individuals with vision impairments or limited mobility, easy-to-see thermostats provide an effortless way to adjust indoor temperatures. These models include large, raised numbers, an audible click with each setting change, and an easy-grip dial cover for added convenience.

SMART LIVING: WHY DIGITAL THERMOSTATS ARE A MUST-HAVE FOR HOMEOWNERS

Upgrading to a digital thermostat offers several advantages over traditional models. Here’s why it’s a smart investment:

  • Lower Energy Bills – Reston’s cost of living can be high, but a digital thermostat helps cut energy waste. By automatically adjusting heating and AC settings, you save money while staying comfortable, even when you’re away.
  • More Accurate Control – Modern thermostats use electronic controls for precise temperature adjustments. They can also detect HVAC issues early, allowing you to schedule repairs before they become costly problems.
  • Easy & Convenient – Smart thermostats handle temperature adjustments for you. Once set up, they work automatically, and you can make changes from your phone or tablet. Want even more HVAC convenience? Click here to explore our furnace maintenance programs.

TROUBLESHOOTING THERMOSTAT ISSUES BEFORE CALLING A RESTON HVAC CONTRACTOR

If your thermostat isn’t working as expected, try these quick fixes before calling 571.346.3940:

  • Check the settings – Ensure your thermostat is set correctly. It’s common to find the switch on ‘heat’ instead of ‘cool’ or vice versa. Also, verify that the temperature setting is appropriate.
  • Look for power issues – A dim or blank display may indicate low power. Try replacing the batteries to see if that restores functionality.
  • Inspect the mounting – If you have a non-digital thermostat, check that it’s securely attached to the wall. A loose unit can cause inaccurate temperature readings.
  • Consider placement – If your thermostat is near a vent, window, or other heat source, it may not measure temperature correctly. Adjust the surroundings if needed.


If the problem persists, contact a Reston HVAC contractor for expert heating and cooling system diagnosis and repair.
