Frequently Asked Questions
How long does a furnace installation take?
Most straightforward replacements are completed in one day. We’ll give you a clear timeline with your quote.
Should I repair or replace my furnace?
If your furnace is older than about 15 years or repair costs are climbing, replacement is often the better value. We’ll show you both options honestly.
Do you install electric furnaces too?
Yes. We install and service both gas and electric furnaces, and can talk you through heat pump options as well.
