HVAC Not Heating? These Tips May Help

It’s a cold winter day and you’re trying to get your heater to work. You do everything you know how to do, but your house remains frigid. Eventually, you give up and bury yourself under enough blankets to smother a penguin while you wait for the repairman to come.

If your HVAC or Central Air Heat Pump isn’t heating, here are tips on how to fix it. Be careful though. HVAC systems and Central Heat Pumps sometimes use harmful chemicals, and an amateur repair job could cause a carbon monoxide leak. There are a lot of ways you could accidentally be harmed while working on an HVAC/Central Heat Pump unit. Do thorough research, and contact a professional if you need anything complicated or major done.

If You Smell Gas, Run

Okay, so technically this isn’t a tip on how to fix your HVAC or Central Air Heat Pump, but if you smell natural gas, get out of the house immediately. Leave the house door open, don’t light any matches or lighters, don’t flip switches on or off (as that could ignite the fumes), and call the fire department or gas utility. This is not a heater problem you can deal with yourself.

Confirm the HVAC & Central Air Heat Pump Is Not Heating

First, you’ll want to make sure the system isn’t functioning. Make sure the thermostat is on, and set it to a high temperature, wait a minute, then check one of the vents to see if any heat is coming out. Also, if your thermostat runs on batteries, make sure the batteries don’t need to be charged or replaced.

You’ll also want to make sure the HVAC & Central Air Heat Pump has power by checking the circuit breakers to see if they’ve tripped. (The circuit breaker on the furnace itself, not the one for the house.) Turn the breaker off for about ten seconds, then flip it back on.

There are also a lot of potential quick fixes to check. Make sure there isn’t a lot of dust inside the thermostat. Open it and carefully clean it.

This source suggests that you “Make sure the date and time are correct on electronic or programmable models – the system may be on a timer.” Additionally, make sure the furnace door is closed, as the system won’t turn on otherwise for safety reasons.

Get Your Furnace Repaired

Reset The Furnace

Once you’ve confirmed the HVAC or heat pump central air is not heating, news source SFGate gives this suggestion: Switch the thermostat off then “confirm that the panel door on the furnace is closed. A switch inside the panel door allows the system to operate when it is fully engaged. If not engaged, the heater won’t come on. Reset the furnace by opening the panel door and turning off the gas or pushing the reset button. Wait five minutes—or follow the instructions in the unit’s manual for a reset—then turn the gas back on.”

Clean Your Furnace

This can help if your HVAC or Heat Pump Central Air hasn’t stopped heating altogether but isn’t working very well.

Each year take some time to vacuum the area by your furnace’s blower. If a lot of dust builds up by the furnace, it can create a fire hazard. Also, don’t store stuff around your furnace for the same reason, not even during the summer, as you may forget about it by winter.

You also may need to clean your burners. The flames coming from your burners should all be about the same size and should be blue. If they’re not, switch off the power and gas, then clean the burners. You can use a vacuum cleaner.

You should also change your filters every 1-3 months or as recommended by the instructions on the filter. A clogged filter will cause your HVAC and Central Heat Pump to not heat as well, so check your filters to see if they need replacing.

If You Need Help

If your furnace has severe problems, you don’t want to tackle it alone. Many furnaces produce carbon monoxide which is a poisonous gas. These are normally released safely away from your home, but if a heater malfunctions, it has the potential to become dangerous (which is why you should buy a carbon monoxide alarm).
