L & H Services Inc. provides professional commercial rooftop unit maintenance programs throughout Beecher, IL and surrounding communities. Regular maintenance keeps your business comfortable and prevents costly breakdowns.
Commercial rooftop units face conditions that residential equipment never encounters—constant weather exposure, extended operating hours, and the demanding requirements of maintaining comfortable conditions for business operations. Without regular maintenance, these harsh conditions accelerate wear and lead to premature failures.
Dirty coils reduce efficiency by up to 30%, worn belts waste energy and can fail without warning, neglected economizers miss free-cooling opportunities, and unchecked refrigerant leaks gradually reduce capacity while driving up energy costs. Regular professional maintenance addresses all of these issues before they become expensive problems.
Maintenance customers also receive priority scheduling for any repairs needed, meaning less downtime if a problem does occur. Our detailed service reports track your equipment's condition over time, helping you plan for future replacement and budget accordingly.
We also provide commercial RTU installation and commercial RTU repair services. For other commercial maintenance, see our refrigeration maintenance and cooking equipment maintenance pages.

Most commercial RTUs should be professionally maintained at least twice per year—once before the cooling season and once before the heating season. Systems running 24/7, in dusty environments, or serving restaurants may need quarterly service. We'll recommend the right schedule based on your specific equipment and operating conditions.
Our comprehensive maintenance visits include coil cleaning, filter replacement, refrigerant check, electrical connection inspection and tightening, belt inspection, economizer testing, safety control verification, drain line check, thermostat calibration, and a complete system performance evaluation. We provide a detailed service report after each visit.
Maintenance program costs depend on the number of units, unit sizes, required service frequency, and any additional services needed. We provide customized quotes based on your specific equipment and needs. The investment typically pays for itself through energy savings and prevented repairs.
While no maintenance program can guarantee zero breakdowns, regular professional maintenance significantly reduces the likelihood of unexpected failures. By catching worn components, low refrigerant, dirty coils, and electrical issues early, we prevent the vast majority of avoidable failures. Maintenance customers also receive priority scheduling for any repairs needed.
Absolutely. We maintain all brands and models of commercial rooftop units regardless of who installed them. Many businesses switch their maintenance to us after being dissatisfied with another provider. We'll assess your equipment and develop a maintenance program tailored to your specific units.
The best time for maintenance is before each major season: spring for cooling preparation and fall for heating preparation. This ensures your system is ready for peak demand. We schedule service at convenient times for your business, including early mornings, evenings, or weekends when needed.
Yes, significantly. Well-maintained commercial RTUs typically last 15-20+ years, while neglected units often fail in 10-12 years. Regular maintenance reduces wear on critical components, keeps the system running at design specifications, and prevents the cascading failures that occur when minor problems go unaddressed.
Yes, our maintenance visits include filter replacement as a standard part of the service. We use the correct filter type and size for your specific equipment. For businesses in dusty environments or with high-filtration requirements, we can arrange more frequent filter changes as part of your program.
Maintenance is designed to be minimally disruptive. Most work occurs on the roof, away from your daily operations. We schedule visits at convenient times and can work during off-hours if needed. Unlike emergency repairs, scheduled maintenance is predictable and planned around your business needs.
Many commercial RTU manufacturers require documented regular maintenance to maintain warranty coverage. Even when not strictly required, a documented maintenance history strengthens any warranty claim. Our detailed service reports provide the documentation you need to protect your warranty.
