Seasonal HVAC Maintenance | ProAir Engineers Yorkshire, Lancashire & East Midlands

With the climate changing year on year at a dramatic rate, seasons shift and so do the demands placed on your commercial air conditioning system. Without proper seasonal maintenance, your HVAC setup can become less efficient, less reliable, and more expensive to operate. At ProAir Engineers, we help businesses across Yorkshire, Lancashire, and the East Midlands, maintain peak air conditioning and refrigeration performance year-round.

In this short guide, we’ll share practical seasonal maintenance tips to prepare your air conditioning system for both summer heatwaves and winter chills.

Why Seasonal Maintenance Matters

Seasonal maintenance isn’t just about comfort — it’s about performance, energy savings, and system longevity. Proactively servicing your HVAC system:

Reduces breakdowns and emergency callouts
Keeps energy bills under control
Extends equipment lifespan
Maintains air quality and consistent airflow
Helps meet regulatory compliance (e.g. TM44 inspections, F-Gas requirements)

Whether you're managing an office in Sheffield, a retail space in Leeds, or a hospitality site in Derby, proactive seasonal HVAC care is a smart investment.

Preparing for Summer

Summers, even across central England can bring unexpected heatwaves with temperatures soaring to the mid 30’s, pushing cooling systems to their limits. Advance preparation of your system in spring ensures it’s ready to perform when the temperatures rise.

Key summer preparation tips:

Check refrigerant levels: Low refrigerant can reduce cooling efficiency and overwork the compressor. Our ProAir engineers check and top up refrigerant as part of seasonal servicing.
Clean condenser coils: Outdoor units collect dirt, leaves, and debris that reduce heat exchange. Cleaning coils improves cooling capacity and energy efficiency.
Test thermostat accuracy: Inaccurate readings can cause overcooling or system inefficiency. Calibrate thermostats and consider upgrading to smart or zoned controls.
Inspect ductwork and vents: Look for blockages, leaks, or dust buildup that can restrict airflow. Sealing duct leaks can improve efficiency by up to 20%.
Replace filters: Dirty filters increase strain on the system and degrade indoor air quality. Replace or clean them regularly to support better airflow and hygiene.

Preparing for Winter

While many associate air conditioning with cooling, most commercial HVAC systems also provide heating through heat pumps or integrated systems. Winter preparation ensures efficient and dependable heating performance across all the regions we serve at ProAir which include Yorkshire, Lancashire, and the East Midlands.

Key winter preparation tips:

Switch to heating mode: Before the cold sets in, test your system’s heating functionality. Sudden cold snaps can catch unprepared businesses off guard.
Check reverse valves and controls: Systems that use heat pumps need functional reversing valves. Our engineers ensure smooth transitions between heating and cooling modes.
Clean indoor units: Dust and particles can accumulate in unused systems. Cleaning indoor components before winter use can prevent odours and poor airflow.
Inspect insulation and sealing: Keep heat in by checking for gaps around windows, doors, and ductwork. Poor insulation makes heating systems work harder.
Schedule preventative maintenance: Winter is a common time for system failures. Preventive maintenance helps spot minor issues before they become major repairs.

Year-Round Best Practices

Some maintenance habits are important all year:

Keep records of servicing and inspections
Monitor energy usage for sudden changes
Train staff on basic system operation and warning signs
Work with a qualified provider like ProAir Engineers for routine checks

Whether your business is based in Sheffield, Preston, Leicester, or anywhere in between, consistent proactive care keeps your systems operating at their best.
