Service contracts and preventative maintenance are very beneficial to your equipment and your piece of mind. The equipment that is covered under the contract will be kept cleaned and maintained to run at optimum efficiency. What is important to note is what equipment is covered under your specific contract and what equipment is not. You may want to review your contract periodically to know what equipment items need to be maintain by internal staff or other contractors. We will always do our best to inform you or suggest maintenance to equipment where we notice issues, but it is up to you to make sure that additional equipment is maintained. Most commonly your service technician will notify you immediately of anything he notices while conducting your service inspection. You may find over time that it would be easiest to add those items/equipment to your contract so that you no longer have to worry about it. A service and maintenance contract can help ease the burden of your worries about your heating, air conditioning, and controls system, but it is important to remember what is specifically covered to prevent any long term or costly damage to your equipment.
