Why should I have regular (or preventative) maintenance? And how often should I have it performed?Nicholson Company2017-03-13T15:44:41-04:00Your heating and cooling systems work incredibly hard to perform their functions for your home every day. The constant stopping, starting and continual operation can wear down any machine if the proper care and maintenance are delayed. However, by performing regular maintenance, you can maximize the lifecycle of your heating or cooling unit and guard against many common equipment failures. Preventive maintenance inspections performed on a regular basis can uncover leaks, rust, rot, soot, frayed wires and corroded electrical contacts that the naked eye may not notice. You should have maintenance done on your system regularly to ensure maximum efficiency and prevent other problems from developing.
