All air conditioning and refrigeration systems, like any other machine, depreciate with time. And if not properly maintained, they progressively lose efficiency, consume more power, and drain your profits.

Without regular maintenance an air conditioner loses its original efficiency steadily every passing year. It is common knowledge that these inefficiencies accelerate in the absence of adequate monitoring and maintenance, thereby causing a lot of inconvenience.

The good news however, is that you can recover most of that lost efficiency through regular maintenance. Studies show that with regular tune-ups a unit will maintain up to 95% of its original efficiency. This means that the cost of a periodic tune-up is recovered very quickly in savings on your monthly power bill and reduced running and repair costs.

Mannai HVAC Service provides you with the finest and most comprehensive range of services to take care of your air conditioning system. With our experience and expertise, we optimize your system and ensure maximum energy efficiency, perfect air distribution and superior indoor air quality.

Very often, customers tend to believe that maintaining air conditioning systems needs no great expertise, and in case of a breakdown, any local AC repair technician can repair it. But while local technicians might be an easy option, they don’t have the kind of extensive knowledge required on the science of cooling. They lack adequate understanding of indoor air quality, airside management and energy efficiency. Neither do they know the designs and circuits well enough for them to optimize your system periodically, nor do they have the infrastructure and resources necessary to handle your system, in case of further eventualities. In fact, relying on them can only cause inconvenience, apart from potential loss of business and productivity. On the other hand, Mannai HVAC Service’s experts and customer focused professionals periodically check your entire system, repair and replace the necessary parts and calibrate the system for perfect air distribution and balancing.
