If you've recently switched your main heating and cooling source over to a heat pump system, it's important to make sure everything is in good working order for optimal use throughout the summer. Subtle signs can occur that may be an underlying indication that your heat pump isn't working properly. Here are a few things that may require a service call by a heating and cooling professional.
A heat pump works by extracting warmer air from either inside or outside and then transferring this heat through a condenser that blows air back into your home. The end result is to generate the ideal temperature inside your home. In the winter months, it can provide a steady source of low to moderate heat to take the edge off of a cold snap. In the summer, a heat pump can cool your home and create a comfortable space inside your living area. You should be able to operate a heat pump without any issues or problems—especially when it comes to your electrical system.
Your home's electrical unit should be able to withstand power surges as the system turns on and again when it cycles. If you've noticed that when the unit is running, you blow a fuse in the electrical panel, it could be an underlying indicator that maybe the auxiliary heating element is drawing too much power from the unit. Calling an electrician or HVAC pro to come out and inspect your entire electrical system and your heat pump is the best way to determine the root cause.
Not Blowing Cold Air
If you've noticed that after your heat pump has turned on and the blower motor has started that there is no cold air coming out, it may be a sign of a dirty condensing unit. The coils located outside in the condensing unit can become corroded or in severe cases, damaged. When this occurs, your unit won't blow cold air in the summertime. You may also want a HVAC professional to check the thermostat inside your home to make sure it's functioning properly. A faulty thermostat can lead to fluctuating temps inside your home.
Unit Won't Turn On
If your heat pump unit won't turn on at all, this is definitely a problem that needs to be addressed. It could be as simple as switching the breaker over to the "on" position or a more problematic issue. Calling in a heating and cooling pro to determine the underlying cause is your best bet. They will check all of the electrical components of the unit including the elements. If an element has gone bad, it can cause the entire unit to malfunction and not turn on at all.
If you've noticed a significant change in the noise of the unit going from heat to cool, you'll want to have the unit serviced. It could be a rattling from expanding ductwork, a loose belt on the motor pulley or a part within the unit that has unexpectedly broken off. An HVAC technician will be able to troubleshoot your unit and fix the noise issue right away.
