The Dunbar Service Difference
Our plans also come with a Dunbar Difference: your technician is part of a TEAM of facilities experts who each have a specialty. Whenever a question or new situation arises, your technician not only knows who to call with questions but also has an inside expert for the best answer. While you will enjoy working with one main technician, you have the resources of several trained mechanical systems experts whenever you need them!
Dunbar’s Preventive Maintenance Plans Save Big in the Long Run
Even though most building owners realize it is better to schedule routine HVAC preventive maintenance services, many operate only in reaction to problems. However, the “fix and repair” process is NOT a maintenance strategy and requires MORE cash in the long run.
Preventive maintenance service calls are scheduled per your agreement on a monthly, quarterly, semi-annual, or annual basis — or any time in between. During these preventive maintenance service visits, Dunbar’s qualified technician inspect and evaluate your heating and cooling equipment, make needed adjustments, and identify essential repairs. These visits may also include:
- Filter changes
- Belt tightening and/or changes
- Condenser coil cleaning
- Motor bearing lubrication
- Compressor oil level checking and topping off
- Refrigerant charge measurement
- Checking for leaks
- Condensate pump checking
- Condensate pan and drain cleaning
Quality means doing it right when no one is looking.
