We've used Sanders & Johnson for 20 years and never been disappointed. Chris did a great job on the preventative heating maintenance and gave us a detailed explanation of how the HVAC in our house worked as we'd just moved in about six months ago. Gave us some tips on how to improve the heating and cooling in the house. Gave us some literature on upgrading the air filtration system with polarized air cleaners and UV air purifiers, but no hard sell. He was on time, very professional and cleaned up the area thoroughly after completing his work.
