To be the best heating, cooling and plumbing company in Oakland County, MI, you have to take pride in the guarantees your company offers. From our Better Than We Found It Guarantee to our On Time Guarantee, we’re sure you’ll feel confident using Kotz.
If we cause any mess we can’t take care of ourselves, Kotz will gladly pay for it to be professionally corrected.
Kotz’s Red Carpet Maintenance members receive top priority—always. We guarantee that as a maintenance customer we will make every effort to service your needs on the very same day that you have an issue.
Kotz promises that you will not find a licensed contractor who can provide you with a comparable installation or work to be performed with the same written guarantees for less. If so, and your work has not begun yet, we will refund the difference plus give you an additional $250 for your trouble.*
*Comparison must be a published, “apples to apples” comparison listing all the company written guarantees. Requests must be in writing within 14 days of estimate provided prior to work being performed. Your request must include the original published comparison as stated above - showing the “apples to apples” comparison.
With our installations, we ensure:
For your safety and peace of mind, Kotz cares and realizes the importance of knowing the contractor and staff you allow in your home:
Kotz understands that not every manufactured piece of plumbing, cooling and heating equipment is going to run 100% perfect 100% of the time.
*Guarantee is on Kotz installed equipment only and must be maintained with our Red Carpet Maintenance Plan.
We go above industry standards by offering an exclusive 10-year parts, 5-year labor warranty, plus 5-year maintenance on new heating and cooling systems. We also offer a 1-year parts and labor warranty on HVAC replacement parts. New water heater and water softener installations have a 2-year labor warranty.
If a Kotz staff member is ever late for your scheduled appointment without advance notification to you, we will credit $25 to your account.
