What We Have Learned from 2 Decades in Rochester Hills
Rochester Hills is known to be an area with larger homes with many surpassing 2,500 square feet. These homes have vast interior areas requiring larger, more powerful systems to cool the home along with system zones, multiple thermostats, and a more complex duct system. Below, we have explained some important AC repair and maintenance considerations for these homes that we have learned over two decades of experience in Rochester Hills.
Technicians Must Maintain Zoning Systems in Larger Homes
Zoning systems work based on dampers in the ductwork opening or closing based on the demands of each zone. During maintenance, these dampers must function correctly relative to the thermostat. If they are not, the thermostat will not be able to control the temperature inside the zone accurately. If necessary, we will lubricate the damper mechanisms, check for obstructions, and replace faulty motor components. We see 15%-30% energy savings for Rochester Hills homes post damper maintenance and repairs.
Airflow Imbalances May Occur Due to Changes in Home Layout
In up to 30% of Rochester Hills homes that we service, we see airflow imbalance occur as a result of changes in home layout. This can be from a wide variety of changes, such as renovations, furniture rearrangements, or the change in the use of a room (ex: home office to living space). Our technicians ensure that the system settings are updated to accurately reflect how each area of the home is used to ensure maximum comfort and even cooling.
Multiple AC Units Must be Synchronized and Coordinated Periodically to Prevent Uneven Cooling
A common maintenance call we receive is from Rochester Hills homeowners with multiple units whose homes are cooling unevenly. There are three common reasons this occurs:
- Load Balancing (40% of cases): Each unit is not handling the appropriate level of cooling demand.
- Thermostat Coordination (40% of cases): Each unit will be connected to a thermostat controlling a designated area (zone). These thermostats must be calibrated and accurately communicated with their units.
- Compressor and Condenser Health (20% of cases): Each unit’s compressor and condenser must be checked for wear and tear, as it is a common cause of uneven cooling.
Our technicians check all three of these at each maintenance job to ensure loads are properly balanced, thermostats are calibrated and coordinated, and the interior components of the unit(s) are still functioning properly.
Leaks and Blockages are More Common in Ductwork
In larger homes like those in Rochester Hills, the ductwork is more complex to accommodate the cooling needs of such a vast indoor area. The source of many cooling issues will be improper duct sealing, ducts that have not been cleaned recently, and obstructions. Issues are more common because the ductwork is longer and more complex in larger homes. We ensure that there are no leaks, the ducts are cleaned, and there are no obstructions as a part of each AC repair and maintenance job.
Systems Generally Experience Longer Run Times in Larger Homes
Because AC systems must operate for longer amounts of time to cool larger homes, more frequent breakdowns are common due to the stress on the compressors, fans, and electronic controls. For these reasons, we perform regular component inspections and lubricate and clean moving parts such as fans and motors to reduce friction and wear. If maintenance is not performed regularly, the system will expend more energy as the strain on the parts increases. We recommend regular maintenance and preventative replacements.
Integrations with Smart Home, Home Automation, and Humidity Control Systems Should Be Checked Regularly
When systems are interconnected, diagnosing system problems can become more difficult. For any of our customers using complex systems, we ensure that communication between the AC system and other home systems is working correctly. We do this by performing regular system audits and ensuring backup systems such as manual AC controls are available, so the home can maintain a comfortable environment even if the integrated system fails.
