Preventative Maintenance
Our goal at Lorenz is to help you get the most out of your HVAC system for as long as you can. Preventative Maintenance is the key to achieving that goal. Not only does annual maintenance prolong the life of your system it keeps it running more efficiently every day. We also offer a free plumbing inspection and tagging of the water shut-off valve to give you peace of mind.
The best time to perform maintenance on your system is before the upcoming heating or cooling seasons. Lorenz Plumbing Heating & Air Conditioning performs all the cleanings and calibrations it takes to keep HVAC systems running reliably. We service all makes and models of equipment.
