When should I get my AC maintained? A Portland tech answers

Annual AC maintenance is a smart investment to keep your AC energy efficient and extend your AC’s lifespan. It also prevents your AC from breaking down on you during the hottest months of the year.

Typically, you should have your AC professionally maintained at least once a year. Most experts recommend that you have your AC maintained in the spring before summer starts.

You should schedule an AC maintenance if:

  • Your AC is taking a longer time to cool your home

  • You haven’t had your AC maintained in over a year

  • Your energy bills are higher than normal despite your usage not changing

In this article, we’ll discuss why the above factors are signs that you should get your AC maintained so you can keep your home cool during the warmest months of the year in Portland.

Sign #1: Your AC is taking a longer time to cool your home

If your AC is taking an unusually long time to cool your home, AC maintenance can improve the efficiency and performance of the AC system.

With annual maintenance, a professional may notice and fix the below problems that can decrease your AC system’s performance:

  • A dirty or clogged filter

  • Refrigerant leaks

  • Leaky ducts

If your AC has a dirty or clogged filter, it can reduce the amount of cold air entering your home. The debris or dirt in the filter can restrict the amount of cold air, which can cause ice to form on the foils. Experts recommend that you replace your air filter every 2-3 months, depending on your filter’s MERV rating which measures how effectively the filter captures particulate matter.

If your AC has a refrigerant leak, the AC cannot function at 100%. As a result, the AC can’t cool the home as efficiently. Signs of refrigerant leaks include a weak flow of air through the vents or warmer air. An HVAC professional can inspect and repair the refrigerant leak with coolant.

If you have leaky air ducts, your conditioned air will be lost to areas of your home that don’t need air conditioning (e.g. the attic or garage). An HVAC professional can seal the ducts or replace them if they are damaged.

An annual AC inspection can catch and resolve these issues before they worsen over time. Skipping maintenance can cause your AC to perform less efficiently.

Sign #2: You haven’t had your AC maintained in over a year

If your AC hasn’t been inspected in over a year, it could be time to have a professional see if parts need to be replaced or repaired.

Without annual maintenance, your unchecked AC system could break down on you when you need it the most. Proper AC maintenance prevents future breakdowns and pricey repairs. In addition, annual AC maintenance can extend your AC’s lifespan.

With maintenance, the average AC lifespan can typically last between 15-20 years. If unchecked, your AC system’s lifespan may decrease and you have to spend money replacing the system sooner than needed. A new HVAC system can typically cost between $2,295 and $7,700 in Portland. However, the average HVAC maintenance is only $100.

Annual AC maintenance also protects parts that are under warranty. In some cases, there may be a stipulation that requires you to maintain these parts by a professional for the warranty to be valid. A valid warranty can significantly help you decrease the cost of a future AC repair or replacement.

Sign #3: Your energy bills are higher than normal despite your usage not changing

If you notice your energy bill is higher but your AC usage hasn’t changed, it could be time to schedule an AC maintenance. Annual AC maintenance can reduce energy costs by 5 to 40 percent depending on your AC system. When AC systems are not maintained properly, they must work harder to cool your home, which increases your energy bills.

Hiring a professional for annual AC maintenance ensures your AC system is performing in optimal condition, which can reduce your energy bills. AC tune-ups typically include cleaning, checking and testing vital parts.

For example, Four Seasons’ 18-point AC tune-up includes:

  • Cycling the AC or heat pump

  • Cleaning & adjusting the blower motor (limited)

  • Inspecting blower wheel

  • Testing safety & limits

  • Tightening electrical connections

  • And more

Hiring a professional for annual AC maintenance can bring you peace of mind that your home will stay cool during the warmer months in Portland.
