When the house was built by Classic Stellar in 1993, they cut a lot of corners and the HVAC subcontractor installed an undersized heatpump. Furthermore, the flexible duct work used to bring cold air to the opposite side of the house (the master bedroom) was (a) undersized, (b) not insulated and (c) hung in a haphazard fashion, allowing many kinks and right turns to impede the flow of cool air. In order to get the bedroom a little cooler for sleeping at night, we really wasted a lot of energy in the rest of the house. We had several companies come to give us bids. One I turned down immediately because he just wanted to sell his special and didn't even bother to inspect the previous setup. Of all the competing companies, I felt that Day & Night's service techs worked hardest to crawl around in the attic to come up with a plan specifically designed for our unique situation. I could have saved a little money with someone else, but I believe what we got will save us money in the long run. Some of the higher cost was due to our adding a Honeywell TruSteam humidifier to the system. There was a little confusion because the first thermostat they installed had to be replaced with one made specifically for the humidifier. There were some error messages which none of their techs could explain. To the service manager's credit, when I complained, he got a regional manager for Honeywell to come to the house with two of the service techs. He basically was teaching them, and told me he would set up some training for all the Day and Night techs to educate them about the product. All our questions were satisfactorily answered. It has been running for about five weeks now, and is a big improvement. We can easily get the temperature in the bedroom down to a comfortable temperature for sleeping without wasting energy. The humdifier works well also. Before the monsoon season, when humidity levels were single digits, our pet cats were no longer afraid to be petted by us for fear of getting shocked. Dry skin is a real problem for my wife, and she noticed an immediate improvement. We also had no problem with the financing, as Day & Night processed the application for a Home Improvement credit card from Wells Fargo for us.
