Furnace Maintenance
Inspection of accessible burners, ignition, safeties, blower operation, filter, venting and heating performance.
Residential and commercial maintenance
Maintenance that checks
more than the filter.
EMH Mechanical performs seasonal maintenance on furnaces, air conditioners, heat pumps, mini-splits, boilers and commercial rooftop equipment. We inspect operating conditions, service the items included in the scope and document problems that need repair.

Maintenance is an inspection and service visit—not a guarantee.
A good maintenance visit gives the equipment an operating check and the owner useful information.
We look for dirty components, drainage problems, worn belts, weak electrical parts, unsafe conditions and other visible issues included in the scheduled scope.
Maintenance cannot prevent every future failure. If testing shows a repair is needed, we explain what was found and separate the corrective work from routine maintenance.
Equipment we maintain
Seasonal checks for the systems that heat, cool and move air.
The maintenance scope is based on the equipment, its condition and the access available at the property.
Air Conditioner Maintenance
Cooling operation, electrical components, coil condition, drainage, airflow and refrigerant-system performance checks.
Heat Pump Maintenance
Heating and cooling operation, defrost components, controls, coils, drainage and refrigerant-system performance.
Mini-Split Maintenance
Indoor filters and coils, outdoor equipment, drainage, controls and operation of ductless heating and cooling systems.
Boiler Maintenance
Accessible burner, venting, pumps, controls, safeties, pressure, visible piping and hydronic-system operation.
Commercial Rooftop Units
Filters, belts, blowers, heating, cooling, drains, electrical components, controls and packaged-equipment operation.
Filters, Belts & Drains
Routine wear and maintenance items checked or replaced when the correct material is available and included in the scope.
Controls & Electrical
Thermostats, contactors, capacitors, relays, sensors, wiring and visible electrical conditions checked as applicable.
Maintenance versus repair
Routine service should not hide corrective work in the fine print.
Inspection, routine service and operating checks.
The scheduled visit covers the equipment and tasks included in the agreed maintenance scope.
- Accessible component inspection
- Operating and safety checks
- Included cleaning and adjustments
- Written or explained findings
Failed parts, leaks, damage and corrective work.
When maintenance identifies a fault, the repair may require more diagnosis, material and labor than the maintenance visit includes.
- Failed electrical or mechanical parts
- Refrigerant leak diagnosis and repair
- Major coil or blower cleaning
- Duct, drain, venting or piping corrections
What to expect
A maintenance visit with a defined scope.
- 01
Identify
We confirm the property, equipment type, number of systems and maintenance requested.
- 02
Inspect
Accessible equipment and routine service items are checked for condition and operation.
- 03
Service
Included cleaning, filters, adjustments and other scheduled maintenance tasks are completed.
- 04
Operate
The equipment is run and checked under the conditions available during the visit.
- 05
Report
We explain items that need attention and separate recommended repair work from maintenance.
Useful findings after the visit
Know what was checked and what still needs attention.
If the equipment needs repair, we explain the issue and identify the additional work. That keeps maintenance, repairs and future recommendations separate instead of rolling everything into an unclear tune-up charge.
Before scheduling
Equipment details help us plan the right visit.
Provide the property address, equipment type, number of systems and any known access requirements.
For commercial properties, roof access, filter quantities, operating hours and site contacts should be confirmed ahead of time.

Maintenance questions
What a tune-up does—and what it does not.
Clear expectations before the visit help separate routine service from repair work.
How often should residential HVAC equipment be maintained?+
The schedule depends on the equipment, manufacturer requirements, operating conditions and how heavily the system is used. Heating equipment is commonly checked before the heating season and cooling equipment before summer. We can recommend a practical schedule after identifying the equipment at the property.
What is included in an HVAC maintenance visit?+
The exact scope depends on the equipment and the service requested. A typical visit includes inspection of accessible components, operating checks, filter and airflow review, cleaning of serviceable items included in the scope and documentation of conditions that need repair. The scheduled scope should be confirmed before the visit.
Is maintenance the same as an HVAC repair?+
No. Maintenance covers the inspection and routine service included in the scheduled scope. Failed parts, refrigerant leaks, damaged wiring, major cleaning, blocked drains and other corrective work may require a separate repair authorization.
Does an air-conditioning tune-up include adding refrigerant?+
Refrigerant is not a consumable that should be added every year. If testing indicates a low charge, the system may have a leak or another problem that needs diagnosis. Leak testing, repair and refrigerant are separate from routine maintenance unless specifically included.
Can HVAC maintenance prevent every breakdown?+
No. Maintenance can identify wear, unsafe conditions, drainage problems, dirty components and other issues before they become larger, but it cannot guarantee that a part will not fail later. It gives the equipment a better operating check and the owner better information about its condition.
Do you maintain commercial rooftop HVAC units?+
Yes. EMH Mechanical maintains packaged rooftop units and other common commercial heating, cooling and ventilation equipment. Commercial scope and frequency are based on the equipment, filters, belts, operating hours and site requirements.
Will EMH Mechanical replace filters during maintenance?+
Filters can be replaced when the correct size and type are available and filter replacement is included in the scheduled scope. Specialty filters, large commercial quantities and damaged filter racks may require separate material or repair work.
Where does EMH Mechanical provide HVAC maintenance?+
Our primary territory includes Northern Oakland County, Northern Macomb County, St. Clair County, Genesee County and Lapeer County. Call with the property address, equipment type and number of systems so we can confirm availability and the appropriate scope.
