Thermostat Replacement and Installation in San Ramon, CA

Is it time to install a thermostat replacement in your San Ramon, CA, home? At Environmental Heating & Air Solutions, we’re committed to creating energy-efficient systems that keep you comfortable without breaking the budget.
Our thermostat installation options can help you save when you upgrade to a smart or programmable option. Older thermostats have one option: on or off. Programmable thermostats let you set times for when the system should run more and when it should run less. Smart thermostats add remote control features, use patterns for automatic temperature adjustment, and detailed reporting to help you find ways to save.
Whether your current thermostat is broken or you just want an upgrade to a device that will help you save on heating and cooling costs, our team at Environmental Heating & Air Solutions can help you find a device that’s compatible and full of the features you want.
Thermostat Replacement in San Ramon

In San Ramon, we get hot, humid summers and plenty of winter nights with sub-40 degree weather. Temperatures even drop below freezing a few times each year, so we need heating and cooling solutions year-round. A thermostat replacement can help you optimize your HVAC use so that you stay comfortable without paying a premium. For example, you can have your home cool down to the lowest setting right before electric surge pricing goes into effect, paying less for hours of cooling. Another option is to set your thermostat to turn the heat down at night or the air conditioner down during the day while you’re at work.
Smart thermostat installation offers a lot of benefits, including:
- Improved energy efficiency
- Remote control over home temperatures
- Improved comfort
- Automated temperature adjustements
Smart thermostat installation gives you control over your home HVAC system in a device you carry around in your pocket. With app-based access, you can adjust the temperature up or down even while on vacation. That means if a storm rolls in and temperatures drop, you can turn the heat on and prevent frozen pipes.
In addition to the everyday savings from automatically adjusting temperatures based on when you’re home and need the extra heating or cooling, you’ll also get regular usage reports. You can use these to control your spending better and to find ways to add cooling without overloading your air conditioner.
