We understand the crucial role your furnace plays in keeping your home warm and comfortable during the colder months.

Our team is well-versed in a variety of furnace types, including gas furnaces, oil furnaces, and electric furnaces, and we handle the three jobs a furnace ever needs: a repair when it stops heating, an annual tune-up so it does not stop heating, and a new installation when the old one has reached the end.

Armstrong Air Furnaces We Install

Every home has different heating requirements, so we take a personalized approach: we assess your current heating system, discuss your requirements, and recommend the furnace that suits the house rather than the one that suits the catalogue.

Our installations use Armstrong Air, and the range spans three efficiency tiers. Which tier makes sense depends on your home's size, insulation, ductwork condition and existing HVAC setup, all of which we look at during the assessment visit.

Efficiency Tiers

  • Ultimate: up to 98% AFUE, Energy Star certified
  • Optimum: up to 97% AFUE, Energy Star certified
  • Supreme: up to 80% AFUE, variable speed fan motor

What Installation Day Looks Like

Why the Annual Tune-Up Matters

Furnace maintenance is the cheapest heating work you will ever pay for, because of what it prevents.

  • Enhanced energy efficiency. Cleaning and optimizing components keeps the furnace operating at peak efficiency and reduces energy waste.
  • Improved indoor air quality. Dust, debris and allergens accumulate in a furnace over time; a service cleans or replaces filters and clears built-up debris.
  • Prevention of costly breakdowns. Minor issues get caught and resolved before they become major problems.
  • Extended lifespan. Keeping components in good condition and airflow correct helps you get more out of the furnace you already own.
  • Warranty compliance. Many furnace manufacturers require regular maintenance as a condition of keeping the warranty valid.

Annual heating tune-ups are part of the Home Comfort Club, which also covers your AC tune-up and takes 15% off repairs.

Furnace Questions

Our team is well-versed in installing a variety of furnace types, including gas furnaces, oil furnaces, and electric furnaces. For repairs and tune-ups we service all makes and models of furnace.

We install Armstrong Air furnaces in three tiers: up to 98% AFUE, up to 97% AFUE, and up to 80% AFUE with a variable speed fan motor. The right tier depends on your home's size, insulation, ductwork condition and existing HVAC setup, which we assess during the consultation before giving you an estimate.

Six steps: an initial consultation and assessment of your home, a detailed estimate with equipment selection, scheduling and preparation, the installation itself, system testing and quality assurance, and a closing customer education walkthrough.

Many furnace manufacturers require regular maintenance as a condition to keep the warranty valid. Scheduling a routine tune-up keeps you compliant with the manufacturer's guidelines and protects your warranty coverage, alongside the efficiency, air quality and breakdown-prevention benefits.
