5 Common HVAC Issues and How to Prevent Them

Your HVAC system is an investment in your space, whether you’re a residential or a commercial property owner. The duct system that circulates air throughout your home keeps your space warm in the winter and cool and comfortable in the summer. An effective HVAC system also prevents mold growth during Portland’s wetter and warmer seasons.

While most split systems have an average lifespan of up to 15 years, there are common problems that can impact their performance and lead to expensive repairs. These problems are avoidable by scheduling regular air duct cleaning services to keep your HVAC system running smoothly.

PNW ProClean is the leading professional air duct cleaning service in Portland, operating across the Portland metro area. As a locally owned and operated company, we take a client-driven approach to our services with advice on how to avoid common HVAC issues.

The 5 Most Common HVAC Issues

There are common problems that can pop up in any HVAC system, leading to a decrease in performance or a total outage. These problems are often quickly fixed or avoidable with HVAC cleaning and maintenance.

1. Dirty Filters
   

   Dirty filters are the most common problem for HVAC systems not working efficiently.

Dirty filters are one of the most common problem for HVAC systems not working efficiently. When dirt, lint, pet hair, and debris catches in the filter, it blocks the airflow and makes the furnace work overtime to maintain your desired temperature. Dirty filters happen when you forget to replace your filter regularly or skip air duct cleaning service and can cause your system to overheat, leading to wear that reduces your system’s lifespan. We recommend setting a schedule to replace your filters or using a filter subscription service that will send you filters on the recommend replacement schedule.

2. Dirty Evaporator Coils or Condenser

Neglecting regular maintenance can lead to a drop in performance. It’s a problem commonly caused by the system’s condenser and evaporator coils becoming dirty. This is especially common in Portland due to the wet climate that promotes mold and plant growth in and around the system if it is outdoors. If you suspect your system is underperforming, give us a call for an inspection.

3. Water Leaks and Leaky Ducts

HVAC systems produce condensation that is directed through to drainpipes. If these pipes become clogged, the water can back up in your system and leak from the unit. A commercial air duct cleaning service will clear your drains to prevent leaks. Your HVAC system can also leak air if there are any holes in the ducting or if they are not sealed properly. Leaky ducts make it harder for your system to work efficiently to achieve your desired room temperature, increasing your property’s energy bills.

4. Dirt and Debris Build Up

Allowing dirt and debris to build up in the ducts of your HVAC system can add extra pressure to the ducts, causing long-term damage. We often find large debris, including trash, construction materials, and even old animal carcasses, when doing a duct cleaning service for a new or recently renovated home. While these issues can impact the performance and longevity of your duct system, they can also negatively impact your health. Excess dirt and debris buildup, or old rotten food and trash sitting in the ducts, can result in mold and cause dust, pollen, and other allergens to become clogged in the ducts and circulate throughout your home, leading to potential respiratory issues.

5. Thermostat Malfunctions

We often find large debris, including trash, construction materials, and even old animal carcasses, when doing a duct cleaning service for a new or recently renovated home.

Several common problems can arise from thermostat malfunctions. These issues are either programmable or non-programmable. You should check your thermostat when you identify a potential issue with your HVAC system to determine if it is set correctly. This is generally a much less expensive fix that something related to the duct system itself.

What is the Most Common Part to Fail on HVAC?

The most common problem with HVAC systems comes from the wiring. These wires often fall victim to corrosion, fraying, and disconnection over time. Wiring problems disrupt the power flow in your system and can result in breakdowns, short-circuiting, or the overheating of your system. Regular maintenance can help identify any wiring problems before they can cause damage.
