I know there are lots of parts at work to make my HVAC system run at full steam, and I'm grateful to all of them for keeping me comfortably cool in the summer and cozy in the winter. When they start to struggle, I owe it to them to make the repairs and replacements happen as soon as possible. And it's a win-win, of course, because there's never a convenient time to have an air conditioning unit or furnace that's out of commission.
When the water pump malfunctions, here's what homeowners need to know about the replacement costs:
Reasons for water pump replacement
Your HVAC appliances accumulate water as they operate. Pools of liquid don't mix well with system performance, which is why there's a water pump - also known as a condensate pump - to drain the excess water. These pumps often lose function over time due to wear and tear, accumulated debris or a failed motor. One of the most obvious signs of water pump trouble is leaking, which becomes apparent when there are small puddles of water accumulating around appliances. Air conditioner or furnace malfunctions may also be caused by a failing condensate pump, but you may need an HVAC professional to inspect the system to confirm that the pump is the issue.
A new condensate pump can cost anywhere from $40 to $300. Labor expenses included, HVAC water pump replacement generally costs about $250 to $500. The factors that may contribute to final price variations include:
Pump type: The cost will vary depending on the brand and model you choose. Generally, your choice will be limited to the specifications of your current pump.

Capacity: HVAC water pumps have a GPM or GPH rate, which indicates how many gallons of water the pump can remove per minute or hour. ConsumerMentor.com advises buying a pump that can remove two to three times your HVAC systems' input condensing rate. You'll also need to consider pump voltage and horsepower, as some appliances and systems require higher levels for proper performance.
Labor: Installation costs will vary depending on the company. Handy homeowners can save on labor expenses by completing the replacement project on their own - but don't tackle the HVAC project if you aren't comfortable with the task. It's not worth jeopardizing your safety or unintentionally creating a more serious issue.
Once installed, keep practicing your preventative HVAC maintenance and your pump should be good to go for many days of heating and cooling to come.
