Common Heating Questions

Q: How often should I change my air filter?

A: Keeping your air filter clean is critical to maintaining your furnace. If you have a 1-inch filter, it should get changed about every 2-3 months. If you have anything thicker than a 1-inch filter, you may be able to change it less often. Always look at the packaging on your filter; to learn about the recommended lifespan.

Q: How do I know if my furnace is working?

A: Is your HVAC turning on and off? Has it been making weird noises? Are your energy bills higher than usual? There are all signs that your furnace may not be working as efficiently as it could. If you answered yes to any of the above questions, contact 72 Degrees today at 515-965-7272.

Q: What temperature should I program my thermostat?

A: For winter, a common thermostat setting is 68-72 degrees Fahrenheit. In the summer, 72-75 degrees Fahrenheit is a common setting.

Q: Is it time to replace or repair my system?

A: When thinking about repairing or replacing your system, the first question you should always ask yourself is how old your system is. If the repair cost multiplied by the area of your system exceeds $5,000 it may be time to replace it. Typically HVAC systems last 15-20 years, depending on proper upkeep.

Q: How often should I get my system serviced?

A: Professional HVAC technicians recommend that you schedule annual service on your systems. If your system is not working properly, it's a good idea to schedule an appointment as soon as possible to prevent potential issues from worsening.

Q: Why should I get annual maintenance on my systems?

A: Annual maintenance keeps the warranty on your systems valid, keeps your system running at its highest efficiency, and prevents future problems from coming up. Annual maintenance ensures that everything is working properly and takes preventative measures towards future problems.
