Frequently Asked Questions

How often you need to fully replace your furnace depends on a variety of factors including the make, model, and maintenance of your unit. Typically, you can expect to replace your furnace every 8 to 15 years. If you’re unsure whether it’s time for a new furnace, call us for a free in-home assessment.

We do everything we can to make the installation process as easy as possible for you. All we ask is that you clear a pathway for us and remove any extra items from your furnace room. This allows us to work more efficiently and prevents potential damage to your belongings.

The length of the installation process will vary depending on a few factors. For a furnace, the estimated installation time is 4 to 6 hours. For a furnace and air conditioning system package, installation can take 6 to 10 hours. We can provide you with a detailed estimate at the time of your in-home assessment.

No, you do not need to be home when we install your furnace. That said, we recommend you’re there to let us in and there when the installation is complete. This allows us to brief you on how to operate your new furnace. It’s also an opportunity for us to discuss any concerns and for you to ask any questions you might have.

Installation costs and times will vary mostly based on what accessory package you choose. If you choose a Premier or Optimum package, the cost and installation time will both increase as we replace all accessories including your ductwork and venting. For a basic package, your existing furnace accessories are reused, shortening the installation time and reducing the cost.

By developing these guarantees, we hold ourselves accountable to our own standards, while giving you the peace of mind that our success hinges on your satisfaction.
