Heating and Air Conditioning questions, answered by experts

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

HVAC systems last around 10 to 30 years. If you complete the recommended maintenance, you can expect your system to reach its maximum life span. The life span also depends on the type of HVAC system. Heat pumps last about 10 to 15 years, AC units last about 15 to 20 years, and furnaces last around 15 to 30 years. Boilers have the longest life span, as they last around 20 to 30 years.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

HVAC systems should be serviced annually, no matter which type of system you have. This service visit should include an inspection, cleaning, and regular maintenance tasks, like flushing the boiler. The best time to do this varies on the system. For heating-based systems, call in a technician sometime during the fall. For air conditioners, go for the spring. Basically, schedule the service call before you plan on amping up HVAC system usage for the season. 

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.
