Heating & A/C Maintenance
A Proactive Approach to HVAC System Care

High-traffic commercial environments can put a lot of strain on A/C and heating systems, which is why our approach to commercial HVAC prioritizes regular maintenance. Maintenance often falls to the bottom of a busy company’s list of priorities, but we aim to change that.
Fewer Surprise Breakdowns
Like any machine, your HVAC system needs regular care in order to operate safely, reliably, and efficiently. Small problems can often be caught during heating or A/C maintenance services – before they escalate into larger problems.
An Expense You Can Budget For
An annual Maintenance Plan allows you to budget for your HVAC care throughout the year. Regular preventative maintenance is the best way to prevent unexpected (and more expensive) breakdowns later.
Maximize Your Equipment Lifespan
Properly cared-for HVAC systems last longer than their neglected counterparts. Regular maintenance protects your investment in your heating and cooling system and avoids the need for premature system replacements.
Minimize Disruptions to Your Business
Equipment breakdowns inevitably happen at the worst times, but maintenance can be scheduled at your convenience. While there’s no way to guarantee that your HVAC system won’t need repairs at some point during its lifespan, regular maintenance is the best way to minimize that risk.
Repair vs. Replacement
When it comes to the HVAC system in your commercial building, the bottom line is important, but so is reliability. You need reliable air conditioning during the busy tourist season and reliable heating for the increasingly busy “off” season. We want to help you get the most life out of your investment, but we also don’t want you to put money out for costly repairs on a system that’s on its last legs. Our team will evaluate your A/C or heating system, explain any issues it is experiencing, and empower you to make an informed choice that makes the most sense for your space, budget, and long-term comfort.
As a general rule, a replacement may be worth considering if your commercial HVAC system is:
- More than 10-15 years old and you’re experiencing issues
- Requiring frequent or increasingly costly out-of-warranty repairs
- Struggling to cool your commercial building evenly
- Driving up energy bills
If a repair is the right answer, we’ll make it happen. If an upgrade makes more sense, we’ll help you explore your options – without pressure.

If you can’t find the answer to your question, feel free to contact us here.
Do you work on all types of commercial heating and A/C systems?
Our technicians have extensive experience repairing and installing many different types of commercial heating and cooling systems, including rooftop units, ductless mini-splits, heat pumps, A/C systems, gas furnaces, and more. We do not service PTAC units or oil furnaces.
How often should I change the filter in my commercial HVAC system?
As a general rule, the filters in your commercial HVAC system should be changed at least once every three months. However, you may need to change your filters more often depending on the type of facility you own.
For example, in high-traffic retail spaces where dust accumulates quickly, or in restaurants where cooking oils enter the air, we recommend checking your filter monthly and changing as needed. A dirty filter can put strain on your heating or cooling system, causing more wear and tear.
How often do you recommend maintenance on my heating and cooling system?
We recommend scheduling preventative maintenance twice per year: once during heating season, and once during A/C season. We offer annual Maintenance Plans to help you budget up front and ensure that a maintenance service is never skipped.
