"Climate Doctors were very punctual and professional. The Angie's List deal I purchased did not cover enough registers for both of my HVAC units, and they kindly allowed me to purchase an additional deal to cover the remaining registers. I far as I can tell they did a thorough job. That being said I was not given any information as to the before/after condition of my HVAC ducts, and I cannot tell any difference in the air quality in my home. It would have been nice to have gotten a better evaluation from the technician (pictures etc.) to make me feel like I wasn't wasting money. Also the Angie's List deal included a free energy audit which was never even mentioned by either of the technicians. I would use them again had I been given a better evaluation of the work performed, but the experience left me feeling that duct cleaning, in general, is a waste of time and money.
