Commercial HVAC Maintenance

Signs You Need Commercial HVAC System Repair

While maintenance can prevent many issues, sometimes repairs are necessary.

Here are some signs that your commercial HVAC system may need repair:

• Strange noises, such as banging or rattling, coming from the unit
• Inconsistent temperatures throughout the building
• Higher than usual energy bills
• Unusual smells, like burning or musty odors

If you notice any of these signs, it’s important to schedule a commercial HVAC system repair as soon as possible to avoid further damage and maintain a comfortable indoor environment.

How Often Should You Schedule HVAC Maintenance?

Routine HVAC maintenance is essential for keeping your system running smoothly. Most commercial systems should be serviced at least twice a year—once in the spring before cooling season and once in the fall before heating season. This schedule helps identify potential issues before they become costly problems and ensures optimal performance year-round.

However, certain industries may require more frequent maintenance. Restaurants, healthcare facilities, and industrial buildings often demand additional servicing due to higher usage and stricter air quality regulations. Regular inspections and cleanings tailored to your specific business needs will help extend equipment life and maximize efficiency.

Remember: It only takes a few missed maintenance sessions for small problems to transform into larger, costly HVAC issues.

Precision Gas & Mechanical Inc.'s Commercial HVAC Maintenance Checklist

Thorough maintenance is key to a reliable and energy-efficient HVAC system. Our team follows a comprehensive checklist to keep your system in top condition, ensuring long-term performance and reduced operating costs.

Our HVAC maintenance includes the following:

• Inspecting and replacing air filters
• Cleaning condenser and evaporator coils
• Checking and calibrating thermostats
• Inspecting and tightening electrical connections
• Lubricating moving parts
• Checking refrigerant levels and inspecting for leaks
• Testing system airflow and ventilation
• Inspecting belts and pulleys for wear
• Examining the heat exchanger for cracks
• Testing safety controls and system shutdown functions

How Often Should Commercial HVAC Filters Be Replaced?

Most commercial HVAC filters should be replaced every 1 to 3 months, depending on usage, filter type, and the cleanliness of the environment.

For example:

• High-traffic buildings may need monthly changes
• Office spaces with moderate use may be fine every 2 to 3 months
• Buildings with special air quality requirements may need more frequent changes

During each visit, we inspect filters and replace them as needed to keep your system efficient and your air clean.

What Is the Lifespan of a Commercial HVAC Unit With Regular Maintenance?

Most commercial HVAC units can last 15 to 25 years, depending on how well they’re taken care of. If regular maintenance isn’t done, the lifespan can shrink by 5 to 10 years. Keeping up with routine service ensures that important parts like motors, fans, coils, and electrical components stay in good condition. This reduces the chances of unexpected breakdowns and helps you maximize your investment over time.

Does AC Coil Cleaning Boost HVAC Efficiency?

Commercial HVAC and general AC maintenance isn’t just about compliance and saving yourself from spending on future repairs. HVAC maintenance can boost your system’s overall efficiency, which will save you money from month to month.

Cleaning AC coils significantly improves HVAC efficiency. Over time, dirt and debris accumulate on the condenser and evaporator coils, restricting airflow and making it harder for your system to transfer heat effectively. This forces the system to work harder, increasing energy consumption and utility costs.

Regular coil cleaning helps maintain peak efficiency, reduces strain on the compressor, and extends the lifespan of your HVAC unit. It also enhances indoor air quality by preventing the buildup of mold and contaminants. Investing in routine coil cleaning is a simple yet highly effective way to improve performance and lower energy expenses.

How Do You Track HVAC Maintenance for Warranty or Inspection Purposes?

We provide full documentation after every visit, including:

• What was inspected
• What was cleaned or replaced
• Notes about parts, performance, or follow-up needs
• Dates of service and technician signatures

This helps with equipment warranties, lease requirements, insurance audits, and inspections. We also keep digital records on file so nothing gets lost.

What Is Predictive HVAC Maintenance and How Is It Different From Preventative?

Predictive HVAC maintenance is a smart way to take care of your system by using data and sensors to keep an eye on how everything is running. Instead of sticking to a set schedule like preventative maintenance, predictive maintenance figures out when something might go wrong and tackles it before it becomes a bigger issue. This means fewer surprise breakdowns, less unnecessary maintenance, and potential savings on repair costs.

Do Rooftop HVAC Units Require Different Maintenance Than Indoor Units?

Rooftop HVAC units (RTUs) and indoor HVAC units need different kinds of care because of their location. Both types need regular maintenance like changing filters, cleaning, and checking for wear and tear, but RTUs are out in the open and have to deal with weather like rain, snow, and extreme temperatures.

This means the sealing, insulation, and parts that can corrode or be damaged by the elements need extra attention. Plus, since RTUs are on the roof, you also need to look out for issues like debris around the unit or roof damage nearby that could affect the system.
