Before You Call: A Quick Money & Time Saving Checklist
We know how frustrating it is when your heating or cooling system stops working—especially on the hottest or coldest days of the year. But before you call for an HVAC repair, a few simple checks might solve the problem and save you time and money.
Here’s a quick HVAC troubleshooting checklist to try before picking up the phone.
1️⃣ Check Your Thermostat
This might seem obvious, but you’d be surprised how often thermostat settings are the culprit!
✔️ Is it set to the correct mode (heat or cool)?
✔️ Are the temperature settings where they should be?
✔️ If your thermostat runs on batteries, try replacing them. A weak battery can cause unexpected issues.
2️⃣ Inspect Your Circuit Breaker
HVAC systems can sometimes trip a breaker, shutting everything down.
✔️ Locate your breaker panel and check if the HVAC circuit has flipped to "off" or "tripped."
✔️ If so, reset it and see if your system starts working again.
If it trips again immediately, stop here and call a professional. That could indicate a deeper electrical issue.
3️⃣ Look at Your Air Filter
A clogged air filter can restrict airflow and even cause your system to shut down.
✔️ Check your filter—if it looks dirty, replace it.
✔️ A fresh filter helps your system run more efficiently and improves air quality in your home.
4️⃣ Check the Power Switch
Many HVAC systems have a power switch near the furnace or air handler.
✔️ Make sure it hasn’t been accidentally turned off. It often looks like a light switch, so it’s easy to flip by mistake!
5️⃣ Inspect the Vents
Blocked vents can prevent your system from heating or cooling properly.
✔️ Walk around your home and ensure all supply and return vents are open.
✔️ Make sure furniture, rugs, or curtains aren’t blocking airflow.
6️⃣ Check the Outdoor Unit
If your AC or Heat Pump isn’t cooling, the outdoor unit might need attention.
✔️ Clear away leaves, dirt, or debris that could block airflow.
✔️ If you see ice on the unit, turn off the system and let it thaw before restarting.
7️⃣ Inspect the Drain Line or Pan
Many HVAC systems have a condensate drain that removes moisture. If it’s clogged, your system might shut off as a safety measure.
✔️ Look for a drain pan near your indoor unit—if it’s full of water, the drain line may be clogged.
✔️ Try clearing the line with a wet/dry vacuum or calling for maintenance.
