Maintenance Services

AC maintenance — essential, not optional.

In Dubai, air conditioning is not a luxury — it is an essential part of daily comfort, health and property maintenance. AC systems operate continuously throughout the year, and without proper care, they gradually lose efficiency, collect dust and contaminants, and affect both cooling performance and indoor air quality. M&H Technical Services provides professional AC maintenance, repair and cleaning services through Ascension Air by M&H — a structured AC care program with multiple service levels tailored to the actual condition of your system.

FAQ

AC Maintenance & Servicing — frequently asked questions.

How often should AC units be serviced?

AC units should generally be serviced at least once every 6 months in Dubai due to heavy usage and weather conditions. Full maintenance such as coil cleaning may be recommended annually depending on the unit condition.

How do I know if my AC needs repair?

Common signs include weak cooling, water leakage, unusual noise, bad odors, weak airflow, frozen coils, frequent shutdowns and higher electricity bills. These usually indicate that professional inspection is needed.

How much does AC maintenance cost?

The cost depends on the type of unit, the condition of the system and the service required. Standard AC servicing may differ from major maintenance such as coil cleaning, gas charging or repair work. A technician inspection helps provide an accurate quotation.

Is it better to repair or replace an AC unit?

This depends on the age of the unit, repair history and the cost of fixing the problem. Many AC issues can be solved through repair, while older systems with repeated failures may be better replaced.

Is gas refilling included in regular AC maintenance?

Gas refilling is not always required and depends on the unit condition. If refrigerant levels are low due to leakage or system issues, the technician will inspect the cause before recommending gas charging.

What is the difference between regular AC service and coil cleaning?

Regular AC service focuses on inspection, filters, drainage and performance checks. Coil cleaning is a deeper maintenance service that removes heavy dirt buildup from internal cooling components to improve system efficiency and cooling performance.
