Here are our guarantees.

100% satisfaction guaranteed.

Our Comfort Guarantee

Get the performance promised.

When we install a new system in your home, we will inform you of the temperature range you can expect from your air conditioner or furnace. If your new system cannot meet this temperature range, our technicians will either repair or replace the furnace or air conditioner at no cost to you.

Our Property Protection Guarantee

When we install a new system in you

At Duffett, we value your personal property and will take steps to protect it when we’re working in and around your home, such as wearing shoe covers and putting down hall runners wherever we work. We’ll repair or replace any items we damage while working in your home.

Our No Lemon Guarantee

Protection against product defects.

When you purchase a new air conditioner or furnace from Duffett, you deserve peace of mind. That’s why we guarantee the heat exchanger in your new furnace for ten years. If your air conditioner’s compressor fails two times in the first five years of ownership, our technicians will replace it.

Our $500 No Frustration Guarantee

We’ll take care of you.

When you purchase a new system from Duffett, we promise to take care of you. If your newly installed heating or cooling system breaks down within the first two years of ownership, we’ll have you back up and running within 24 hours of your call. If not, we’ll compensate you $500.

Our Energy Savings Guarantee

See the energy savings you expect.

When we install a new HVAC system in your home, we will set a percentage of your heating or cooling cost that you can expect at minimum. If your new system doesn’t meet this minimum threshold, we will reimburse you for the difference between what you actually saved and what we promised you’d save.
