Service Contracts Are a Waste of Money
When elevator inspectors don’t find anything wrong, were those inspections a waste of money? HVAC systems aren’t at risk of plummeting to the basement, but poor maintenance risks unhealthy air, surprise capital costs, excess utility spend, repair bills… not to mention lost productivity and all the headaches and budget nightmares.
Service contracts look like an expense, but ask any engineer, and they’ll tell you the opposite is true. They’re an asset with great KPI: saving future costs, mitigating risk, extending the life of capital spending, cutting energy spend plus… you’ll face fewer headaches and nightmare budget reviews.
In fact, we’re so sure of the value of a service contract, that Linc Service offers agreements that replace units that fail during the life a guaranteed lifetime protection. If you’re still doubting the value of preventive maintenance, talk to the team that believes in it so much they’ll take on the cost of asset replacement.
The Truth
Caring for facility assets is a plus for profitability.

Anyone Can Change a Filter
Maybe you change your own filters at home. “How hard can it be?” you ask, and you’re right, in that it’s not the most exciting challenge HVAC technicians face. But an improperly placed filter in a packaged rooftop unit damages the asset, cuts your efficiency, and puts your indoor air quality at risk. And think about this: how often do you forget to change your filter at home?
Maybe the biggest risk to treating a filter change like a filter change is opportunity cost. Just banging open a panel, switching a filter, and checking a box wastes a lot of concrete data. A qualified technician uses a filter change to discover issues before they become issues you’ll have to deal with.
And like a lot of tasks today, a filter change isn’t just a filter change. Making sure the schedule is kept, efficiently managing the filter change with other tasks, making sure documentation is done and all the administrative boxes are checked, that’s all part of it. For instance, using the proper filter (and not arbitrarily going for a cheaper one) may be required by a building’s LEED certification. A well-managed, professional process goes beyond filter changes. Devoting time and expertise to real preventive maintenance pays off.
The Truth
Your HVAC performance depends on the people that help you care for it.
Both a one-time checkup and full preventive maintenance still require great technicians to provide the best outcomes for your business.
To avoid reducing cost in one area, only to find it increases costs in another, look for a service provider with:
- Measurable results
- Custom solutions for your business goals
- Experienced professionals
Great facility service providers are easy to spot: they’re the companies that have taken the time to build a great team.

If It's Not Broke, Don't Fix It
Preventative maintenance will save you money! Waiting for a part to break pretty much guarantees more damage is done throughout your system than if you’d just fixed the problem earlier. It’s also a pretty safe bet the system has been wasting energy, running inefficiently to make up for whatever’s going wrong. Those are two hefty premiums you’re paying when you delay maintenance. Not to mention that preventative maintenance could have extended the life of that part, so that’s three ways you’re paying for it. Now consider that the repair’s costs are likely larger, and the productivity you’ve lost from the system going offline… you get the picture.
The Truth
Preventative maintenance avoids excess costs from inefficiency, breakdown, and excessive wear.
