Affordable A/C Systems is a great company with wonderful professional people to help you. What's even greater is they are accredited with BBB with A+ RATING. They saved us a lot of money through the AEP Coolsavers Program. AEP Coolsavers Program is a free energy savings program for both commercial and residential AEP customers. Their friendly informative professional service techs came out to service all of our units to every last detail from washing down units, inspection of AC performance, changing out filters and even changing out batteries in the thermostats. Their courteous phone staff assisted us with all our issues and problems. Not only did they prolong the life of our A/C units and saved us energy, but gave us saving of $1500.00. Wow, now that's savings and TOTAL CUSTOMER SATISFACTION! Thank you Affordable A/C Systems.
