At ARQ Building Services we understand that the electrical, mechanical (HVAC), and pluming systems are the lifeblood of any facility. Particularly, the proper operation of the heating and air conditioning is essential to the comfort of the buildings inhabitants. This is one reason why a comprehensive HVAC preventative maintenance program is so important. Another factor that makes a PM program a must, is money. A system that is properly maintained is more likely to meet its full life expectancy. A system that is not properly maintained will often deteriorate sooner, break-down more often, and eventually fail completely. The constant repair and eventual replacement cost of a system will usually far exceed the annual cost of a preventative maintenance program.
