How To Prevent Frozen Pumps

February 1st, 2018 by kcunningham

An HVAC system is a staple need in every American home in the aspect of comfort. It’s the friend you can count on to bring you warmth during the cold winters, and helps you chill during the scorching summers. But like any friend, it has its flaws and lapses.

It’s natural for heat pumps to freeze during frigid temperatures, but can this be prevented? And What do we do when this happens?

What Causes Frozen Heat Pumps?

Tremendously cold temperatures is what usually causes these pumps to freeze – obviously! But another cause could be low refrigerant levels. Have a professional make sure that your pump can meet the required amount of refrigerant needed.

We cannot stress enough how important it is to work with licensed and reputable HVAC companies as improper installation of your system can cause the pump to freeze. If this is the case, refer to a registered contractor, like Thornton.

Prevent Frozen Heat Pumps

Get A Model With A Defrost Feature – There are a few old units that are equipped with a defrosting component, but if you have one that isn’t, it would be ideal that you get a newer model that does. This way it would be a lesser hassle, and lesser money spent in the long-term process on your part.

Have Routine Maintenance And Check-up – Getting your system regularly maintained is important. This would provide it with needed new parts and repairs to cope up with the wear and tear over time. A check-up aside from the maintenance should also be strictly practiced so that unexpected damages and complications could be spotted and addressed as soon as possible. It’s ideal that you have a maintenance schedule once a year and have your HVAC examined twice a year.

Remove Debris Surrounding The Unit – Clean the unit and remove any unnecessary debris within two feet of the unit, such as leaves. Make sure that the unit is not operating when doing this.

Pumps Should Be Situated In Insulated Walls – This may cost you more, but it saves you big as it prevents future expenses on repairs.

Close Doors And Windows During Cold Weather – Keep the cold out by minimizing possible options where it can enter. You’re not just keeping yourself warm, but also your heat pump.

Stop Changing The Thermostat Temperature – Have your thermostat stay at the same temperature throughout the day. Changing it makes your pump prone to freezing.

Cover Your Unit – following a two feet clearance, create a canopy above your unit, this way it prevents the snow and any sort of rubbish from falling on it. It also is helpful during summer as it provides shade.

Defrosting The Heat Pump

Normally, a frozen pump is nothing to be worried about so you can finally get out your sigh of relief. Modern heating and cooling systems have a built-in defrosting feature with them. So if you own one of these, most likely, it’s gonna be a walk in the park for you. These features commonly are paired with sensors that automatically indicates it to start defrosting when needed. The whole process can span from 2 to 10 minutes depending on the nature of your HVAC system.

If the built-in feature isn’t doing the trick then its advisable you call and consult professionals on this. For more details on how to prevent issues with your HVAC system, contact Thornton Heating at (847) 905-1608.
