Frequently Asked Questions

It’s always good to be prepared and have your furnace installed before you need it. We recommend having your furnace assessed in the early fall for maintenance, repairs, or replacement. A preemptive assessment allows plenty of time for us to perform an installation or any repairs that are needed. It also reduces the chances of an unexpected breakdown when you need your furnace most.

Most furnaces need to be fully replaced every 8 to 15 years. The life of your furnace will vary based on the brand and model of furnace, as well as the maintenance it has received. Because the lifespan can vary, we offer free in-home assessments for your furnace and your peace of mind.

We want your furnace installation to go as smoothly as possible. In order to do this, we ask that you move any items that could block our path to your furnace room or block access to your furnace. Moving any items that could be in the way also helps prevent damage to your belongings.

If we’re installing a furnace, you can expect the installation time to be 4 to 6 hours. If we’re installing a packaged system with a furnace and air conditioning, the installation time will be longer and is usually between 6 to 10 hours. The amount of time it takes will also depend on the package you purchase and whether we are replacing your vents and ducts in addition to the furnace.

You don’t need to be home for the entire installation, but we do recommend that you’re home when we arrive and when we leave. This gives us a chance to discuss any issues and go over everything you need to know about your new furnace. It also gives you a chance to ask us any questions.

For up to 2 years from the day we install your heating or cooling unit, we will repair, replace, or refund anything necessary until you are completely happy with your new system. That’s our guarantee to you.
