I've used this company for a few years for seasonal maintenance. This year I happened to mention to my technician, Chris, that despite clean filters I was seeing a lot of dust and I was getting more respiratory illness. He said it would be good to look at duct work and see if everything was intact. What he saw..and took pictures of explained a lot! It was a total mess..and to make matters worse my 9 year old A/C u it wasn't doing the best job. Now I am the proud owner of a new energy efficient Trane unit, new duct work and insulation and a cool digital thermostat that I can operate remotely. Thank you Chris for your attention to detail and getting the work done so quickly! You are a great addition to the AHR team!
