Q: Should I run my fan continuously on the thermostat or set it in the auto position?
A: "That’s generally a personal preference. Newer furnaces have a recirculation mode for when you run the fan continuously. On an older furnace, it can be fairly expensive to run the fan all the time."
Q: How often should my system be serviced?
A: "Most utility companies recommend you service a furnace and air conditioner once a year. As the system collects dirt, often in small particles, it becomes less efficient."
Q: Can I shut off vents in certain parts of my house?
A: "Typically, it's not recommended. When you shut off more than one vent, you alter the airflow of the system, which can negatively affect the performance of both the air conditioner and furnace. It can also harm the life expectancy of the equipment. When the heat transfers through the walls and windows of that room, it often winds up in the house anyway."
Q: What’s a zone system?
A: "A zone system has one furnace and one air conditioner, but electronic dampers can be installed that allow for multiple thermostats in the house, so you can open and close ducts depending on which rooms need air."
Q: To what temperature should I set my thermostat?
A: "We recommend you set it to a level with which you're comfortable. We don't recommend moving the thermostat up and down more than a few degrees. Move it one degree at a time to find the optimum comfort level and give it an opportunity to work. It's much more efficient to find a comfortable point and let it stay there than it is to turn it up and down."
Q: Should I set my thermostat up or down when I'm out of the house?
A: "Maybe a couple of degrees, but no more than five. Heat is stored in walls and furniture, so if you let it build up in the house while you're out, it's going to take much longer for the air conditioner to get all that heat back out of the house when you return."
Q: Are there ways to improve the air quality inside my house?
A: "We often install the IQAir filter system, which is one of the most efficient air filtration systems available and can be installed using an existing central ductwork system. It takes three years before any maintenance is required, and it removes 95 to 99 percent of particles that are .3 microns and higher. Unlike most high-efficiency electric filters that cause ozone depletion, IQAir is a non-electric filter."
