Furnace installation

Furnace installation is a job for a professional – homeowners should not attempt to install a furnace on their own. The equipment price is the biggest portion of the total cost to install furnace systems in most cases, and this equipment needs to be properly installed and service by someone who knows what they’re doing. Don’t risk damage to your new furnace or costly energy waste due to improper furnace installation.

Before you call an HVAC contractor for furnace installation, do some research into the different furnace brands available. Today’s furnaces are packed with incredible technology that boosts energy efficiency and enhances user experience – look into the options available and see the brands and models that have features which help you meet your operational savings, sustainability, and comfort goals.

Furnace Maintenance Tips

Just like vehicles, machinery, and even other household appliances, furnaces need care over their years of service to keep them in good working order. A good furnace maintenance strategy combines professional and DIY tasks to give your furnace a great start going into heating season and keep it running throughout the coming months.

Make sure your furnace maintenance strategy includes the following:

  • Professional furnace preventative maintenance in the fall. Ideally, schedule your service appointment prior to the first time your furnace is needed this season.
  • Change your air filter. Follow the manufacturer’s recommended interval for filter changes and check your furnace filter monthly throughout heating season to determine if a change is needed sooner, as filters often require more frequent filter replacement during periods of heavy system use.
  • Open all vents and registers throughout the home and make sure there are no carpets, pieces of furniture, or other items atop or in front of their openings so that heated air is able to properly flow through the ducts and into your indoor living areas.
  • Reset your programmable thermostat schedules for heating season. Take into consideration your household’s changing schedule and your heating budget to choose energy efficient setpoints and schedules that deliver adequate indoor comfort levels without sacrificing your family’s comfort.

Cost to Repair Furnace

On top of the actual furnace repair, most HVAC contractors charge a service call fee, which covers system diagnosis. A service call for furnace repair typically costs between $50 to $100. For emergency furnace repair overnight or on weekends or holidays, expect to pay more.

The cost to repair furnace systems varies between $100 to more than $1,000. On average, homeowners pay about $270 per furnace repair. Some approximate average costs to repair furnace systems include:

  • $300 to $400 to repair faulty ignitors
  • $50 to $200+ to replace a thermostat
  • $150 for blower motor repairs
  • $450 for blower motor replacement
  • $500 to $1,200 for heat exchanger replacement
