What Our Clients Say About Us?
I recently had a new Coleman furnace put in my mobile home, but before Mr. Cortez just replaced it- he and his crew checked everything out thoroughly to see if my old heater could be fixed.
Being a senior of 83 years old and a former teacher he did everything possible to save me money, he was very professional, did excellent work and I certainly would highly recommend Sinclair heating and air conditioning to anyone who needs his service.
