"I had used No-Frost about ten years ago to completely replace the furnace and heat pump in my townhouse and also add an Aprilaire furnace humidifier. I chose them at that point not only because they were the low bid but because they explained everything clearly, provided great documentation and also were a Trane dealer and offered a ten year warranty. The installation and service in my townhouse were first rate and I had no trouble at all with the system for over ten years. We moved to another house less than a year ago and inherited a system with a very old furnace humidifier that the previous owner had not been using, had disconnected the supply and drain lines, and it had no filter. I called two contractors for estimates on replacing the unit. The first contractor sent a crew out to look at the system and give an estimate. When I called No-Frost, Eileen quoted me a price over the phone that was half the price of the other contractor. They would also give me a furnace/heat pump system check at no charge. Given my history with No-Frost, it was a No-Brainer. They were able to schedule within a week with an Aprilaire 600 with the advanced humidistat. The tech arrived on time. Our furnace and water heater are both tucked into a closet in our finished basement and there is not a lot of room to maneuver. Additionally, since we were replacing an existing installation, the new humidifier needed to fit in the same space. Initially, the tech had serious doubts about whether the new humidifier was going to fit. After some deliberation, we decided to give it a try. About twenty minutes later the tech called me down and showed me that it actually fit perfectly, with more than enough room open the unit to change the filter. Additionally, we had requested the Aprilaire unit with the automatic exterior humidity sensor. The tech explained to me that he had that system installed in his house and was not satisfied with the performance. There was a way to modify the installation to avoid running the outside sensor and improve performance, which he did. During the free system check, the tech also pointed out that there were signs of black mold inside the furnace. I had also previously noted some mold on one of the ceiling air vents. The tech gave me a recommendation for a duct cleaning company. Within two hours the installation was complete. There was an existing PVC drain line that went into the floor in the utility closet that we used for the humidifier drain. The system ran for about twenty minutes and all was well. About ten minutes after the tech had left, I started getting a puddle of water on the floor around the PVC drain. I shut the unit off and immediately called No-Frost. Eileen told me she would send the tech right back. Within ten minutes he was back, and he determined that there was a problem with the drain line that went into the concrete floor. I would need to call a plumber. Amazingly, I was able to get a plumber, Robert Bookhultz, out within two hours. They snaked the drain line to the outside, excavated the end (which had been buried under 6 inches of dirt), and added a 12 foot extension. Drain problem solved. The humidifier works great. Our HVAC system is about 15 years old and I will certainly call No-Frost when it is time to replace it."
