Questions
Do I need a programmable thermostat to save energy?
While programmable thermostats offer convenience, manual adjustments can also save energy. Lowering temperatures by 3-10°F when away or asleep reduces energy costs without requiring new equipment.
How often should I change my air filter?
Check filters monthly, especially during peak seasons. Replace when dirty, but at minimum every 3 months to maintain system efficiency and indoor air quality.
What does a typical maintenance check-up include?
Our maintenance includes thermostat calibration, electrical connection checks, coil cleaning, refrigerant level verification, and safety inspections to ensure optimal system performance.
Where should my thermostat be installed?
Install thermostats on interior walls away from windows, doors, and heat sources. Avoid placement behind furniture to ensure accurate temperature readings and efficient system operation.
Will setting the thermostat back make a noticeable difference?
Yes - reducing heating temperatures by 10-15°F for 8 hours saves 5-15% annually. Proper setback strategies significantly reduce energy costs without compromising comfort.
