We had a technician from K&M Shillingford replace our 75 gallon water heater. Their quote was very competitive and the installation work was done quickly and correctly. The city inspector just came and approved the work, saying that he was impressed and pleased with the workmanship that he saw. We are very pleased with our experience with K&M Shillingford.
- Margaret Ede

K&M Shillingford helped us get our water heater working again after it had been down for several days, and the company who installed it couldn’t fix it. The service reps were so personable and made the experience painless. Kudos to Dale for taking such great care!

- Cheryl Lawson

K&M Shillingford installed our geothermal heating and cooling at our ranch and it works fine. They have serviced our traditional heating and cooling units here at our house in Tulsa and they have found and corrected problems from another company. I am always satisfied with their work and the good crew they have.
