HVAC Maintenance

Most costly HVAC failures start as small, catchable problems: a dirty coil, a weak capacitor, a clogged filter, a refrigerant charge that has drifted off spec. Seasonal maintenance is where those get caught, before they turn into a no-cool or no-heat call.

A maintenance visit covers both the indoor and outdoor equipment, electrical connections, and airflow, with a straightforward report on anything that needs attention.

What to expect from HVAC maintenance

  • Seasonal tune-ups for cooling and heating systems
  • Coil cleaning, electrical checks, and refrigerant charge verification
  • Filter and airflow inspection
  • Straightforward reporting on anything that needs attention

HVAC Maintenance FAQs

How often should an HVAC system be serviced?

Most residential systems benefit from a tune-up twice a year, once before cooling season and once before heating season, to catch small issues before they cause a breakdown.

What does an HVAC maintenance visit include?

A maintenance visit covers coil cleaning, electrical connection checks, refrigerant charge verification, filter and airflow inspection, and a report on anything that needs attention.

Does regular maintenance actually prevent breakdowns?

Many of the most common HVAC failures, such as weak capacitors, dirty coils, low refrigerant charge, and clogged filters, are exactly the kind of issues a maintenance visit is designed to catch before they cause the system to fail.

Do you offer maintenance for commercial systems as well as residential?

Yes, we provide maintenance plans for both residential systems and commercial equipment such as rooftop package units.

New Construction HVAC

New construction and major additions give a rare chance to design the HVAC system around the building instead of working around equipment that is already there. We work from plans to size equipment, lay out ductwork, and place returns before walls close in.

We coordinate with builders and general contractors directly, so HVAC rough-in lines up with the rest of the build schedule instead of holding it up.

What to expect on a new build

  • System design from plans, before walls close in
  • Ductwork and equipment sized to the finished building
  • Direct coordination with builders and general contractors
  • Inspections and permitting handled as part of the job

New Construction HVAC FAQs

At what point in the build should HVAC be involved?

As early as possible, ideally during the plan review stage, so equipment sizing, ductwork routing, and return placement are worked out before walls and ceilings close in.

Do you work directly with builders and general contractors?

Yes, we coordinate directly with the builder or general contractor so HVAC rough-in and inspections line up with the rest of the construction schedule.

Can you design an HVAC system from architectural plans?

Yes, we size equipment and lay out ductwork from the building plans rather than waiting until the space is framed.

Do you handle new construction for additions and remodels, not just full builds?

Yes, the same design and installation process applies to additions and major remodels, sized to the changes being made to the home.

Commercial HVAC

Commercial HVAC problems come with a different set of stakes than a residential call: rooftop package units, multi-zone systems, and downtime that affects staff, customers, or inventory rather than just comfort. We work around a business's hours wherever the job allows it.

From a single rooftop unit to a multi-zone commercial building, we handle repair, replacement, and the ongoing maintenance that keeps a system off the emergency-call list.

What commercial clients can expect

  • Rooftop package units and multi-zone commercial systems
  • Scheduled around business hours wherever the job allows
  • Preventive maintenance plans for commercial accounts
  • Licensed for both residential and commercial work

Commercial HVAC FAQs

What types of commercial properties do you service?

We service offices, retail spaces, restaurants, and light industrial buildings, on both rooftop package units and multi-zone commercial systems.

Can HVAC work be scheduled outside business hours?

Wherever the job allows it, yes. We work with commercial accounts to schedule repairs and installations around occupied hours to limit disruption.

Do you offer preventive maintenance contracts for commercial accounts?

Yes, scheduled maintenance plans are available for commercial equipment to reduce the likelihood of unexpected downtime.

Are you licensed for commercial HVAC work, not just residential?

Yes, our license covers both residential and commercial HVAC work.
