Furnace Installation Questions, Answered
How long does a furnace installation take?
Most standard installs are done in one day — usually four to eight hours. Timing depends on the system and whether ductwork or venting needs modifying. We'll give you a clear timeline with your quote.
How do I choose the right size furnace?
With a professional load calculation (Manual J) — not a rule of thumb. We factor in your square footage, insulation, windows, and ductwork so the system heats evenly and efficiently. Proper sizing is the single most important part of any install.
What furnace types do you install?
Gas furnaces, electric furnaces, dual-fuel systems, and heat pumps, plus high-efficiency upgrades and smart thermostats. As a Lennox Premier Dealer we install all major brands and recommend the best fit for your home.
Should I repair or replace my furnace?
Consider a new system if your furnace is over about 15 years old, needs frequent repairs, has a cracked heat exchanger, or can't keep you comfortable. If it's newer and the issue is minor, a repair may be smarter. We'll give an honest recommendation.
Do you handle permits and old-unit removal?
Yes. We pull any required permits, install to code, and haul away and dispose of your old furnace — the whole process is handled for you from start to finish.
What warranties come with a new furnace?
New systems come with manufacturer parts warranties (often up to 10 years when registered), and we back our installation workmanship too. We'll walk you through the exact coverage for the system you choose.
How much does a new furnace installation cost?
It depends on the system, its size and efficiency, and any ductwork or venting work needed — so we don't guess. We give a clear, written quote up front, and our free Instant Quote prices a system online in minutes. Financing is available.
Do you offer financing for a new furnace?
Yes. We offer flexible financing so you can install the right, efficient system now and pay over time. Ask about current options when you request your free estimate or Instant Quote.
