Keep Your Heating & Air Conditioning Systems Running Smoothly

Routine maintenance is essential to keeping your HVAC systems running smoothly and avoiding unexpected disruptions. Our maintenance programs cover all key aspects of your system, from filter changes and cleaning to inspecting critical components like heat exchangers, fans, and refrigerant levels. By addressing small issues early, we help you avoid expensive repairs and ensure optimal comfort for your tenants or employees.

In addition to preventing breakdowns, regular maintenance enhances the energy efficiency of your system, saving you money on utility bills over time. At Aquinas HVAC, we’re dedicated to helping you protect your investment and keep your property comfortable, no matter the season.

Commercial and Multi-Family HVAC Maintenance Expertise

At Aquinas HVAC, we don’t offer one-size-fits-all maintenance. We tailor each program to the type of property because commercial and multi-family systems operate under different pressures, schedules, and expectations.

Commercial HVAC Maintenance

Commercial HVAC systems must support steady usage across office suites, retail floors, lobbies, or light-industrial spaces. We maintain rooftop units, split systems, and packaged equipment to ensure efficient heating and cooling across zones. Our technicians schedule visits to minimize business interruptions and keep systems compliant with local energy codes, just like we do during commercial HVAC installations and upgrades. This proactive approach helps avoid emergency service calls that could disrupt operations or customer experiences.

Multi-Family HVAC Maintenance

Multi-family HVAC maintenance needs can be even more complex. Equipment often serves multiple tenants with different comfort needs and usage habits. Our team is experienced in servicing systems for apartments, duplexes, and mixed-use buildings, where shared infrastructure and resident satisfaction go hand in hand. We inspect indoor and outdoor units, clear drain lines, and address any signs of wear that could cause future complaints or uneven temperatures. In buildings with aging systems or tight access, we also help identify upgrade needs before they become urgent. If it’s time for an upgrade or a more comprehensive plan, explore our multi-family HVAC services.

Whether your priority is lowering energy use, extending system life, or avoiding tenant complaints, our maintenance programs support property performance year-round. With Aquinas HVAC, you can trust that every checkup, cleaning, and inspection is handled by a team that understands commercial and multi-family environments—down to the last detail.

Regular HVAC Maintenance Saves You Money

In addition to comfort and efficiency, regular maintenance provides substantial financial benefits. Investing in routine HVAC maintenance not only keeps your equipment running smoothly but also results in significant cost savings over time. At Aquinas HVAC, we understand that proactive care helps prevent expensive repairs by identifying issues early. By addressing problems before they escalate, you reduce the risk of costly system failures and extend the lifespan of your equipment.

Here is a list of our maintenance services to keep your system performing at its best:

  • Change air filters
  • Test the heating system
  • Test the cooling system
  • Inspect evaporator coils
  • Blow out condensate drain line with nitrogen
  • Tighten all electrical connections
  • Inspect the refrigerant lines

A well-maintained unit operates more efficiently, consuming less energy and lowering monthly utility costs. Whether you manage a commercial or multi-family property, our tailored maintenance programs ensure that your HVAC equipment operates at peak efficiency, maximizing savings while providing consistent comfort year-round.
