5 Common HVAC Questions & Answers. Answered By HVAC Experts

1. How can I set up my new furnace for zone heating?

It sounds like your installer either didn’t know or didn’t want to deal with old zone motors. Working with old zone motors is not one of my favorite things either. It’s not uncommon to see old zone motors that don’t work well with new systems. I always recommend replacing the zone system at the same time that you replace the furnace. This will ensure that the zone system and furnace are compatible. Feel free to us and I would be happy to walk you through it or get you a bid for replacing it. On average, new zone motors cost $2,000-$3,500.

2. What should I do if I don’t have heat in the middle of the night, but I also don’t have a service agreement?

In the winter, we actually provide furnace repair service 24 hours a day, 7 days a week. This is a common practice for HVAC professionals in the Twin Cities area. If you give us a call this winter, we should be there within hours. No service agreement required!

3. How often should I change the filter in my whole-home humidifier?

In most cities, you should change the filter in your whole-home humidifier once a year at the beginning of the heating season. If you have well water or hard water, you may need to change it for a second time in the middle of the heating season. In addition, some manufacturers recommend that you look at the water panel after 300 hours of use so take a good look at the new water panel when you put it in. Once you hit 300 hours, inspect it for calcium, rust, or other deposits that would make the water run through the panel too fast.

4. What are the pros and cons of rocket mass heaters?

This was an interesting question that left us scratching our heads! Because we primarily work with gas furnaces, rocket mass heaters are outside of our realm of knowledge. However, owning a rocket mass heater sure seems like a neat idea!

5. How can you tell if it’s time to replace your furnace?

How often you replace your furnace depends on the age and efficiency of your current furnace. If you’ve owned your furnace for ten or more years, have a technician look at the integrity of the heat exchanger. The heat exchanger should be checked every year if your furnace is more than ten years old. If your furnace is 18-20 years old, I would start collecting quotes from companies in order to have a ball park estimate of how much a new furnace would cost. This will help you budget and avoid making rushed decisions if your furnace suddenly breaks down and must be replaced.
