HVAC FAQs Answered!

We get lots of questions about heating and cooling! Here are answers to some of the most common HVAC questions we get asked.

What is the best filtration system for my HVAC system?

Overall, the best bet for price and performance is a media air cleaner. This is a 4-5” replaceable filter that goes in a cabinet in your furnace’s return air duct. For most homes, these filters last 1 year. They’re very effective and impose much less air restriction on the HVAC system than the 1” pleated filter you get at the hardware store.

Should I run my blower all the time?

Maybe. It’s helpful to have the blower running if you want to balance out the temperature between rooms and floors. Also, the constant circulation means air is always being sucked into the return to be filtered, reducing dust a bit. In the summer, when the cooling is cycling, the constant airflow can cause higher levels of humidity as it evaporates the water left on the cooling coil when the air conditioner shuts off. Try it both ways and see what works the best for you!

Should I set my temperature back when I’m gone?

In most cases, yes. Studies have shown that a reasonable setback over an 8 hour period leads to energy savings. But don’t get carried away; 5-7° is probably the most you’d want to adjust your HVAC system.

Are WiFi thermostats really better?

There are a couple of great advantages with a WiFi thermostat: you can change the temperature from your phone or tablet while you’re away. If you’ll be coming home early or staying out late and want to override your program accordingly, you can do so. You can also monitor your house while you’re away. Many of them can also email or text you if the house gets too warm, too cold, too humid, or if the power goes out.
