No-Cool Diagnosis
Testing of electrical components, controls, airflow, temperatures and refrigerant-system operation.
Residential AC service
Cooling that keeps up
with Michigan summers.
EMH Mechanical repairs, replaces and installs residential central air conditioning. We diagnose the equipment, refrigerant system, airflow, controls and drainage before recommending the next step.

Check the whole cooling system
The outdoor unit is only part of the air conditioner.
Central air conditioning depends on the outdoor equipment, indoor coil, blower, ductwork, thermostat, refrigerant circuit and condensate drainage.
A problem in any of those areas can cause poor cooling, high humidity, ice buildup, water leakage or equipment shutdown. We test the system before deciding what should be repaired.
Residential cooling work
From a no-cool call to a complete AC installation.
Air conditioning service and installation for existing homes, additions, renovations and homes adding central cooling for the first time.
Air Conditioner Repair
Repair of failed capacitors, contactors, motors, controls and other serviceable cooling components.
AC Replacement
Removal and replacement planned around the home, indoor equipment, ductwork and cooling load.
New Central Air
Cooling installation for homes without existing AC when the furnace, ductwork and utilities can support it.
Refrigerant Diagnosis
Operating-pressure, temperature and leak diagnosis before refrigerant-related repair is recommended.
Coils & Drainage
Indoor and outdoor coil concerns, condensate drains, drain pans and condensate-pump service.
Thermostats & Controls
Cooling controls, standard and smart thermostats and related low-voltage diagnosis.
Airflow & Ductwork
Blower setup, return-air problems and duct restrictions that affect cooling and dehumidification.
Diagnosis before parts
Cooling problems should be confirmed—not guessed at.
A system can stop cooling because of an electrical failure, airflow problem, dirty or damaged coil, refrigerant leak, drainage issue or control problem. The symptom alone does not identify the repair.
We test the equipment and document what we find before recommending repair or replacement.
Request AC DiagnosisRepair or replace?
The failed part is only one part of the decision.
When the failure is isolated and the system is still worth fixing.
Many cooling failures can be repaired. We look at the failed component, coil condition, compressor operation, repair history, refrigerant system and condition of the indoor equipment.
- The repair is reasonable for the equipment's age
- Replacement parts are available
- The coils and compressor remain serviceable
- The system has not developed repeated problems
When the repair puts too much money into an aging or failing system.
Replacement may make more sense when the AC has a major refrigerant-system failure, repeated breakdowns or other problems beyond the immediate repair.
- The compressor or coil has failed
- Repair costs are high compared with replacement
- Breakdowns are becoming frequent
- The system has ongoing comfort or humidity problems
AC replacement process
Indoor and outdoor equipment planned as one system.
- 01
Evaluate
We review the existing cooling equipment, furnace or air handler, ductwork, electrical and installation space.
- 02
Build the Options
Equipment and scope are selected around the home, cooling load, budget and requested performance.
- 03
Schedule
We confirm equipment, access, outdoor placement, timing and work that must be completed by others.
- 04
Install
The old equipment is removed and the new indoor coil, outdoor unit, line connections and drainage are completed.
- 05
Startup
We operate the system, check temperatures and airflow and provide applicable warranty information.

Air conditioning questions
Useful information before the service call.
If the AC breaker keeps tripping, the equipment is smoking or wiring appears damaged, leave the system off and schedule service.
What should I check before calling for an AC problem?+
Make sure the thermostat is set to cool, the temperature setting is below the room temperature and the furnace or air-handler switch and breakers are on. Check the filter if it is easy to reach. If the breaker trips again after being reset, leave it off and schedule service.
Why is the air conditioner running but not cooling the house?+
Possible causes include a dirty filter or coil, airflow restriction, failed outdoor component, refrigerant problem, thermostat issue or an equipment problem inside the home. Testing is needed before the cause can be confirmed.
Why is there ice on the refrigerant line or indoor coil?+
A frozen coil can be caused by low airflow, a refrigerant problem, a failed blower or another operating issue. Shut the cooling system off and allow the ice to melt before service so the equipment can be tested properly.
When should an air conditioner be repaired instead of replaced?+
Repair may make sense when the failure is isolated, parts are available and the rest of the system is in serviceable condition. We also consider equipment age, repair history, refrigerant system condition and the cost of the proposed repair.
How do you determine the correct AC size?+
Square footage is only one factor. Windows, insulation, air leakage, home layout, ductwork and the cooling load all affect equipment selection. A larger air conditioner is not automatically better and can create comfort and humidity problems.
Can EMH Mechanical add central air to a home that does not have it?+
Yes, when the existing furnace, electrical service, ductwork and installation space can support it. We review the indoor equipment, airflow, outdoor location, line-set route, drainage and electrical requirements before building the scope.
What warranty comes with a new residential AC system?+
Qualifying residential installations include EMH Mechanical's transferable 12-year labor warranty. Manufacturer coverage and registration requirements vary by equipment. Final warranty terms are included with the installation paperwork.
