As temperatures drop, you can’t have your furnace go down too! If it does happen to go down, meaning it is no longer providing the efficient heat your home needs to stay comfortable, contact your local furnace experts at Pacific Air Systems.

We’re often asked, “What are common furnace problems I should be on the lookout for?” People want to take care of their furnace and minimize the need for large repairs.

Here are the 3 most common furnace problems we’ve witnessed below and proactive solutions to keep your heating system running all winter long.


Dirty filters are the cause of many furnace issues. Not only does a dirty filter make your furnace work overtime, but also it greatly affects the indoor air quality of your home. It’s important to change your filter according to your furnace specifications. Many thermostats will even tell you when the air filter needs to be replaced.

The most effective way to avoid dealing with dirty filters and the poor health effects of decreased indoor air quality, schedule basic preventative maintenance services. This includes having your HVAC system checked annually.

During maintenance, ask your technician what the best practice is when it comes to changing your dirty filters. It’s important to use the right filter for your specific system.

Lack of maintenance, including not being vigilant when it comes to changing your filter, is the first common furnace problem.


Your furnace is prone to wear and tear just like anything else with a mechanical system. One of the frequent problems experienced with HVAC systems is leaky ductwork. Through the repetition of cycling back and forth from heat and then cold, ductwork experiences fatigue which leads to leaks. This is dangerous and requires repair before it can perform optimally for your family.

If you notice any leaks in your system, give us a call. An HVAC professional is ready to handle ductwork repair, before, during, or after the winter months. Your furnace will be working overtime; be aware of any signs that your unit needs some TLC.



As mentioned above, HVAC units experience fatigue and need annual maintenance. A furnace will also age. There’s not much that can be done; time will inevitably tear down the mechanical system. If your furnace is an older model, about a decade old, this is why your unit is acting wonky or performing inefficiently.

Whereas modern units promote an efficiency level of about 90%, an older unit may only be able to perform at a 60%. Not only does this minimize the comfort level, it inconveniently adds to your utility bill.

If it seems like you’d like to consider a replacement unit, Pacific Air Systems offers a large selection of the best HVAC equipment. When compared to the frustration of inefficient airflow and expensive monthly bills, replacing your unit may be the most cost-effective answer to your furnace woes.

This holiday season, Pacific Air Systems would like to wish you a Merry Christmas and Happy New Year!

May your family be warm, comfortable, and merry all winter long. If you need any assistance when it comes to your furnace — a question or to schedule maintenance, we’re open 24/7, even on holidays.
