Repair or Replace Your Heating System?

The best time to consider a new furnace is before you need one. It’s not uncommon for a heating system to fail during a deep freeze, because it’s working so hard to keep you warm. When this happens, you have no choice but to make a quick choice, or you’ll freeze, too. Better to be prepared and start researching new furnaces when:

  • The furnace blows cold air
  • The airflow from the heating vents is weak
  • Your heating bill is higher than usual
  • The furnace turns on and off frequently (or runs constantly)
  • The unit is already 10 or more years old

The experts at Interstate Heating are always available to do an inspection and furnace repair. You can trust our NATE-certified technicians—many who have 15+ years of experience diagnosing and fixing furnace issues—to give you honest, reliable advice about what repairs are needed or if replacement is the better solution.

If it makes more sense to replace your furnace, Interstate is one of Wisconsin’s largest residential Carrier® dealers. We offer a range of systems (including ductless split systems and heat pumps) and will explain which is the best option for your home. We may also recommend adding indoor air quality products—like air purifiers or whole-home humidifiers—that work with your new heating system to elevate your comfort level even further.

Trust Southeast Wisconsin’s Furnace Installation and Replacements Expert

When installing a new furnace is the best solution, who installs it is just as important as what furnace you select. The pros at Interstate, backed by more than 50 years of experience and extensive knowledge of new construction installations, can be trusted to get the job done right. We’ll recommend one that is just the right size for your home—one that is too large will waste energy and money, yet one that is too small will struggle to keep your home warm. We can also help you take advantage of rebates, tax credits, energy rewards, and affordable finance options to make your purchase more convenient.

Your Trusted Furnace Experts for Installation and Beyond

After your new furnace is installed, ask your installation technician about our Residential Maintenance Agreement, the convenient and affordable way to ensure your home heating system maintains optimal performance. Preventative maintenance is the best way to increase the longevity of your investment and keep minor repair issues from becoming a furnace repair emergency. Our Residential Maintenance Agreement makes routine cleaning and care affordable and easy.
