Keep your business air conditioning running smoothly with regular servicing
Your commercial air conditioning works hard behind the scenes to keep your employees comfortable and your clients happy. But just like a commercial boiler or a company car, your cooling system needs routine care to stay in top working order.
At Happy Heat, we offer hassle free servicing plans tailored for local businesses. Regular checks prevent unexpected breakdowns, keep your energy bills low, and ensure the air inside your workplace stays fresh and clean every day of the year.

What is included in a Happy Heat commercial service?
When our qualified engineers visit your premises, we carry out a thorough inspection and clean to make sure every part of your system performs at its best.
Filter cleaning and sanitisation
We clean or replace air filters to remove trapped dust, allergens, and bacteria, improving health and safety for your team.
Coil and component cleaning
Built up grime on internal coils forces your unit to work harder. We clean the coils to restore maximum airflow and efficiency.
Refrigerant level checks
We inspect coolant levels and check for subtle leaks that could hurt performance or increase energy consumption.
Electrical and safety checks
Our team inspects all electrical wiring, connections, and controls to ensure the unit operates safely.
Drainage and pump testing
We clear condensate drains and test lift pumps to stop water leaks before they cause damage to your decor.
The benefits of routine servicing for your workplace
Investing in annual maintenance pays for itself by keeping your running costs low and protecting your business operations.
Lower monthly costs
A clean, well maintained air conditioner uses far less electricity to cool or heat your building, cutting your overall energy bills.
Extended equipment lifespan
Regular care reduces strain on key components like the compressor, helping your system last for years longer.
Cleaner, healthier air
Clean filters mean fewer airborne contaminants, helping reduce staff illness and creating a fresher space for customers.
