Frequently Asked Questions

• What size furnace do I need for my home?

  The right furnace size depends on your home's square footage, insulation quality, climate zone, and ceiling height. A unit that's too small won't heat effectively, while an oversized furnace will cycle on and off frequently, wasting energy and causing uneven temperatures. Our blog articles include BTU calculators and sizing guides to help you find the perfect fit.

• How often should I replace my HVAC air filter?

  Most HVAC air filters should be replaced every 30 to 90 days, depending on the filter type, household size, and whether you have pets. High-efficiency filters like MERV 13 or higher may need more frequent changes due to their denser material. Regular replacement improves indoor air quality and keeps your system running efficiently.

• What is the difference between a heat pump and a furnace?

  A heat pump transfers heat from outdoor air to warm your home and can reverse the process for cooling, making it an all-in-one solution. A furnace generates heat by burning fuel (gas, oil, or propane) or using electric resistance. Heat pumps are more energy-efficient in mild climates, while furnaces perform better in regions with harsh winters.

• How can I improve my home's heating efficiency?

  Start by sealing air leaks around windows, doors, and ductwork. Adding proper insulation to your attic and walls makes a significant difference. Schedule annual HVAC maintenance, upgrade to a programmable thermostat, and consider replacing older equipment with high-efficiency models rated 95% AFUE or higher.

• What does AFUE rating mean?

  AFUE stands for Annual Fuel Utilization Efficiency and measures how efficiently a furnace converts fuel into heat. A furnace with a 96% AFUE rating converts 96 cents of every dollar spent on fuel into actual heat, with only 4 cents lost to exhaust. Higher AFUE ratings mean lower energy bills and reduced environmental impact.

• When should I replace my furnace or boiler?

  Consider replacing your heating system if it's over 15 to 20 years old, requires frequent repairs, or your energy bills have increased significantly. Other warning signs include uneven heating, strange noises, and difficulty maintaining consistent temperatures. Modern high-efficiency furnaces and boilers can reduce heating costs by up to 30%.

• What is a modulating furnace?

  A modulating furnace adjusts its flame and blower speed in small increments to match your home's exact heating demand. Unlike single-stage units that only run at full capacity, modulating furnaces provide more consistent temperatures, quieter operation, and improved energy efficiency. They're ideal for homeowners seeking maximum comfort and lower utility costs.

• How do I choose between a gas and electric furnace?

  Your choice between a gas furnace and an electric furnace depends on local utility costs, existing infrastructure, and climate. Gas furnaces typically have lower operating costs and heat more quickly, but require a gas line and proper venting. Electric furnaces have lower upfront costs and simpler installation but may cost more to run in colder regions.

• What maintenance does my heating system need?

  Annual professional maintenance should include inspecting the heat exchanger, cleaning burners, checking the flue system, testing safety controls, and lubricating moving parts. Homeowners should regularly replace air filters, keep vents unobstructed, and check thermostat batteries. Proper maintenance extends equipment life and prevents costly emergency repairs.

• Are smart thermostats worth the investment?

  Smart thermostats can reduce heating costs by 10% to 15% by learning your schedule and adjusting temperatures automatically. Features like remote control via smartphone, energy usage reports, and integration with home automation systems add convenience. Most homeowners see a return on investment within one to two heating seasons.
