Preventive Maintenance
Catch the small stuff before it becomes an emergency repair.
Most HVAC breakdowns are the tail end of a slow decline — dirty coils, weak capacitors, clogged filters, drifting refrigerant. A twice-yearly preventive maintenance visit from GERARDO HVAC LLC across Fort Dodge, Webster City, Humboldt, and Eagle Grove, Iowa keeps small issues from turning into no-heat or no-cool emergencies.
Signs You Need Preventive Maintenance
- It has been over a year since a technician touched your system
- Bills are creeping up with no change in habits
- Rooms don't heat or cool as evenly as they used to
- You've never replaced the filter or forget how long ago it was
- Airflow at the vents feels weaker than last season
- The condenser or evaporator has visible dust or biofilm
How I Approach Preventive Maintenance
A real preventive maintenance visit is a full inspection — condenser and evaporator coil cleaning, filter replacement, electrical component testing, refrigerant charge verification, drain line clearing, and a written report of anything that needs attention now or in the near future.
What's Included
- Condenser coil cleaning (outdoor)
- Evaporator coil cleaning (indoor)
- Filter replacement and sizing check
- Capacitor, contactor, and motor testing
- Refrigerant pressure and superheat verification
- Drain line clearing and float-switch test
- Written system inspection report

Preventive Maintenance — FAQs
How often should I have preventive maintenance done?
Twice a year is ideal — AC in spring, furnace in fall. Once a year is the bare minimum for reliable operation.
What's actually included in a maintenance visit?
Coil cleaning, filter service, electrical component testing, refrigerant checks, drain clearing, and a written report — not just a quick look and a filter swap.
Will maintenance really lower my energy bills?
Yes, in most cases. A dirty coil or weak capacitor can quietly raise your bill 10-30% before you notice a cooling problem.
Do you offer maintenance for commercial rooftop units?
Yes — commercial rooftop HVAC maintenance is part of what I do, including restaurants and small businesses.

Preventive Maintenance
Condenser and evaporator coil cleaning, filter replacement, seasonal maintenance and system inspections.
beforeCondenser coil packed with cottonwood and debris — restricting airflow and forcing the system to overwork.
afterSame unit after a full coil cleaning — restored airflow, lower energy use, longer system life.
beforeCondenser pulled apart for deep service — heavy dirt buildup on coil walls and compressor base.
afterAfter a full deep clean — compressor degreased, coil fins clear, ready for peak-season performance.

Bottom of an outdoor unit completely matted with dust and pet hair — airflow choked off at the base.

Entire condenser face caked in dirt and cottonwood — common cause of high power bills and weak cooling.
