Frequently Asked Questions

Unfortunately, there’s no hard and fast rule for this scenario. Your best bet is to gain a thorough understanding of both options and choose whichever one makes the most sense for you and your family. One of our Home Comfort Advisors would be happy to assist.

We do our best to ensure that repairs are completed on the same day, within 4 hours of when the call was made.

No, we charge the same rate for all repairs, regardless of time. If you need a repair after-hours, over a weekend, or even on a holiday, we will never charge you extra. We are available to take calls 24/7.

Absolutely. The best way to do this is to have a yearly maintenance check performed by a licensed technician. These regular maintenance checks will not only help to decrease major repairs and reduce system downtime, they will also lengthen the lifespan of your unit.

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.

No Hassle™

If your system breaks down and you are left without temperature control within the first 2 years of installment, we will fix it within 24 hours of the time you call or give you $1000 for the inconvenience.  No Hassle™ –  guaranteed.


Just Right™

We guarantee not only that the system we install will control the temperature of your home precisely for a full 5 years, but we also guarantee no temperature variance of over 2 degrees Celsius at the thermostat.
