Heating & Cooling FAQs

For optimal air quality and system efficiency, we recommend checking your furnace filter monthly and replacing it every 1-3 months, depending on usage, pets, and allergies.

A heat pump is an energy-efficient HVAC system that provides both heating and cooling. In summer, it moves heat out of your home like an AC. In winter, it reverses the process, extracting heat from the outdoor air (even cold air) and transferring it inside.

This could be due to several reasons, including a tripped pilot light, a clogged filter, a faulty thermostat, or issues with the furnace's limit switch. Our furnace repair technicians can quickly diagnose and fix the problem.

Smart thermostats offer convenience and energy savings. They allow you to control your system remotely, learn your preferences, provide energy usage reports, and can even integrate with other smart home devices.

Regular HVAC maintenance, upgrading energy-efficient systems, improving insulation, sealing ducts, and using programmable or smart thermostats are all effective ways to boost your home's energy efficiency.
