FAQs

Should I do my furnace and air-conditioner at the same time?

Yes, you get the absolute best efficiency when the furnace and the air-conditioning equipment have been tested together and tuned for a perfect match for best performance.

What is the life expectancy of a new furnace?

The recommendation is to upgrade your furnace every 12 to 15 years. A good maintenance program will extend the life of your furnace to the upper limits of 15+ years.

Why is it important to have regular maintenance on my new furnace home comfort system?

In the same way that an automobile requires periodic maintenance for optimal performance, a home comfort system should be regularly inspected by a qualified technician.

How can I find out about rebates and tax credits on my new HVAC equipment?

The first thing to know is rebates are only available through companies that are certified through the North American Technician Excellence program (NATE).

We try to answer commonly asked questions like these on the FAQ page of our website.
