When your HVAC system is operating with dirty coils, it can use up to 37% more energy than if they were clean. A coil that has been fouled up with dirt, grease, or grime cannot work as efficiently as it once did. Only Regular maintenance can stop this so make sure you implement coil cleaning as part of your regular maintenance program. #hvac #hvaclife #hvactechnician #hvacservice #hvacrepair #hvacmaintenance #cooling #furnace #repair #Mississauga #Toronto #oakville #heatingandcooling #refrigeration #airconditioning #hvacexperts #vettedforlife #nextlevelservice Dolphin Mechanical Services provides a set of HVAC repairs in Mississauga, Toronto, and Oakville.
