When homeowners in Montgomery County, MD think about energy savings, one common strategy is to turn the thermostat off when no one is home. While that sounds smart in theory, the reality is that keeping your thermostat on all the time — especially with the right settings — can actually increase energy efficiency, improve comfort, and protect your HVAC system.
At AMS Air Conditioning and Heating, we’ve been helping families in Gaithersburg, Rockville, Potomac, Bethesda and surrounding areas stay comfortable year-round. Here’s why keeping your thermostat on can be the better choice — and how it benefits your home and your wallet.
✅ 1. More Efficient Temperature Control
When you shut your HVAC system off completely and later turn it back on, it has to work overtime to restore your desired temperature. That sudden demand uses more energy than maintaining a steady indoor climate. A constantly running thermostat helps your system run more efficiently and reduces overall energy consumption.
✅ 2. Reduces Wear and Tear on Your HVAC System
Every time your HVAC system turns on from a full stop, it puts stress on major components like the compressor, fan motor, and blower. Over time, that stress leads to breakdowns and costly repairs. By maintaining a consistent temperature with the thermostat left on, your system cycles more gently, extending its lifespan and minimizing the risk of expensive failures.
✅ 3. Better Air Quality for Your Home
A constantly running system means better air circulation. This allows your HVAC filters to catch more dust, pollen, and allergens, and it keeps humidity levels in check — something Gaithersburg-area homeowners know is important during muggy summer months. Good air flow also prevents mold growth and stale air from settling.
✅ 4. Smart Thermostats Make It Easy
Using a smart thermostat or programmable thermostat is the perfect way to keep your system running efficiently. These thermostats learn your schedule and automatically adjust the temperature — keeping it consistent while still optimizing energy use. If you don’t have one yet, AMS Air Conditioning and Heating can install and program one for you.
✅ 5. Comfort Without Compromise
There’s nothing worse than walking into a hot house in July or a freezing living room in January. By keeping your thermostat on, you ensure consistent indoor comfort — no waiting for your system to catch up. This reduces daily stress and makes your home a more pleasant place to be, year-round.
✅ BONUS TIP: Use the “Auto” Fan Setting
To avoid unnecessary fan use, keep your thermostat set to “Auto” rather than “On.” This way, your fan only runs when needed for heating or cooling, helping you save energy while maintaining a steady temperature.
