Should I Change My Commercial HVAC Filter?

Your commercial HVAC filter plays an important role. It filters dust and debris out of the air that circulates through your space. In this way, it helps keep both your building and your HVAC equipment clean. However, commercial HVAC filters do not last forever. Eventually, they become saturated with debris and need to be changed. The following are a few key signs that it’s time to change your commercial HVAC filter.

1. It’s been more than three months.

Most businesses need to change their HVAC filters every three months. This is true of stores, office buildings, and most medical and health centers. If it has been more than three months since you changed your HVAC filter, installing a new one will help restore your system’s efficiency. You won’t have to call a commercial HVAC repair company as often if you change your filters on schedule, either.

In order to stay on schedule with future filter changes, try buying several filters at once. This way, you always have a spare on hand. Also, write the filter change dates into your schedule, or set up phone/email reminders.

2. It’s been more than a month in a “dirty” facility.

If you run a business that produces a lot of debris, then it’s a good idea to change your HVAC filters monthly. This guideline applies in most manufacturing businesses, and also in auto shops and other repair shops. Once a filter gets clogged, it will no longer do its job. Debris will start to build up in the air, which is not healthy in facilities like these. Regular filter changes make for a happier, healthier workplace.

3. Your energy bills have gone up.

If your energy bills have gone up, this could be because you’re not changing your air filter often enough. Once the filter becomes clogged, the system has to work harder to push air through the filter, which drives your energy bills up. Change your filter, and see if your energy bills go down. If they do not, have a commercial HVAC contractor come look at your system. You may need some other, minor repairs to restore efficiency.

High energy bills can also mean your filter is too restrictive. Filters with a high MERV rating catch a lot of small debris, but they also restrict airflow too much for some systems. Ask your commercial HVAC service company to recommend filters with the ideal MERV rating for your needs.

4. Your space is dirty.

Have you begun to notice more dust accumulating on your surfaces? This means you need to change your air filter. You may also benefit from switching to a more effective filter — one with a slightly higher MERV rating. These filters capture smaller particulate debris, leading to cleaner air.

Change your filters regularly, and you’ll reduce your need for HVAC repairs. With that being said, feel free to contact H & H Commercial Services if your HVAC equipment is struggling. We offer commercial heating and air conditioning repair Philadelphia residents can trust.

Commercial HVAC Odors & What They Mean

Business owners often become concerned if their HVAC system begins emitting unfamiliar odors. And indeed, some HVAC odors are a reason for concern. Others, however, are quite normal or are simply an indication of a minor, temporary issue. Review the following odors and what they mean, and you’ll know what to do the next time your commercial HVAC system starts smelling.

Burning Dust

When you first turn the HVAC system on for the season, you may notice an odor that reminds you of burning or scorched dust. Don’t let this one alarm you too much. Some dust probably settled on the burner while the unit was turned off. Once the dust burns up, the odor should go away.

If you still notice the dusty odor a day or two after turning the system off, then you may want to have a commercial HVAC service company come clean and maintain your system. Regular system maintenance can prevent these odors from occurring in the first place.

Rotten Eggs

A “rotten eggs” odor is perhaps the most concerning odor that can come from HVAC equipment. It means you have a gas leak. Natural gas is not naturally scented, but gas companies add sulfur to the gas to ensure that leaks don’t go unnoticed.

Gas leaks are an emergency, especially in a commercial setting. If you smell rotten eggs, evacuate the building and call your commercial HVAC repair company immediately.

Metallic Odors

Sometimes you may notice an odor that reminds you of hot or burning metal. This is usually an indication that the wiring or electrical components of your HVAC system are malfunctioning. What you’re smelling could be a wire or other component overheating.

While most commercial HVAC equipment is designed with emergency shut-offs to turn the equipment off before a fire starts, a metallic odor is still a reason for concern. Turn your system off, and call a local commercial HVAC contractor. Your system may need a new blower motor, ball bearing, or belt.

Mold and Mildew

When the heat or air conditioning turns on, do you notice a musty, moldy smell wafting through the room? Such odors are common. They are not particularly dangerous, although mold can cause allergy symptoms in some people. However, mold and mildew odors often indicate that your condensate drain is clogged, causing water to pool and encourage mold growth. It’s wise to let an HVAC contractor take a look.

Oily Smells

If you have an oil-burning furnace or boiler, then be on the lookout for oily smells. These odors generally indicate that you have an oil leak. It could be in the oil tank, in the oil lines, or in the heater itself. Call commercial HVAC mechanical contractors Philadelphia residents trust to work on oil-burning systems, and have the leak addressed before any more oil is wasted.

If you notice these or other odors coming from your HVAC equipment, don’t hesitate to contact H & H Commercial Services. We offer commercial heating and air conditioning repair Philadelphia business owners can rely on.
