As a homeowner, maintaining a comfortable indoor environment regardless of external weather conditions is paramount. At JJJ TECHS Heating and Air Conditioning, we recognize the significance of optimal temperatures indoors. That's why we provide a comprehensive range of heating and cooling services, encompassing HVAC installation, repair, maintenance, and replacement, ensuring year-round comfort. A pivotal element in regulating indoor temperatures is the thermostat, which controls your home's heating and cooling system based on sensed temperatures.


Thermostats come in various types, including digital, programmable, and smart thermostats. Digital thermostats, the most prevalent type, offer straightforward temperature setting adjustments. Programmable thermostats, however, allow for tailored temperature schedules throughout the day or week, facilitating energy conservation and cost reduction.


Smart thermostats represent the latest advancement in thermostat technology, connecting to your home's Wi-Fi network. They enable remote control of your heating and cooling system via smartphone apps or voice commands. Additionally, smart thermostats adapt to your schedule, enhancing energy efficiency beyond programmable counterparts.
