I purchased an Angie's List Big Deal coupon for $69 for a 21-point furnace tuneup. The technician, Justin, arrived on time, was very professional, and gave me an assessment of my heating and air conditioning system. He said the furnace is fine, but the air conditioner would need to be replaced. In the springtime, I purchased their service contract and they came out on April 6 for the spring inspection. Again Justin told me that the air conditioner needed to be replaced, and he showed me areas where the coils, etc., were rusted. I asked about an air purifier, which I was considering for my seasonal allergies. He recommended the REME Air Purification System and gave me some informational materials. I did some research on air purifiers, and then asked my allergist if he thought this particular air purifier would be a good investment. He said it is similar to the system they use in the research lab and looks very good. The new air conditioner and REME system were installed on April 19. The bottom box of the furnace wasn?t the correct size, so they returned another day with the correct size. The whole thing was around $8,000. I have now had time to assess the new system and I like it very much. The combination of the air conditioner and the air purifier keeps the house cool without having to turn the thermostat down very far. I am already noticing a difference in my heating bill. I am very pleased with their products and service.
