Air Conditioning in Ann Arbor, MI

Temperature differences between floors are common in Ann Arbor homes and typically result from several factors. Hot air naturally rises, making upper levels warmer, but excessive temperature differences often indicate insufficient insulation, ductwork issues, or an improperly sized air conditioning system. Our technicians can perform a comprehensive evaluation to identify the specific cause in your home and recommend solutions such as zoning systems, ductwork modifications, or improved attic insulation that will create more consistent temperatures throughout your house.

Ann Arbor homeowners can choose from several cooling system types. Central air conditioning systems use ductwork to distribute cool air throughout the entire home and are most common in our area. Ductless mini-split systems provide targeted cooling without requiring ductwork, making them ideal for home additions or older houses. Heat pumps offer both heating and cooling from a single unit, efficiently transferring heat rather than generating it. Window units and portable air conditioners provide temporary or supplemental cooling for specific areas. Our experts can help you determine which type best suits your comfort needs and budget.

Your Ann Arbor air conditioning system likely needs professional attention if you notice any of these warning signs: strange noises during operation (grinding, squealing, or banging), insufficient cooling or airflow from vents, warm or lukewarm air instead of cool air, frequent cycling on and off, unexplained increases in energy bills, or complete system failure. Even subtle changes in performance can indicate developing problems that, if addressed early, can prevent more extensive damage and expensive repairs. Regular maintenance can catch many issues before they affect your comfort.

Properly sizing an air conditioner for your Ann Arbor home involves more than just square footage calculations. Our technicians perform a detailed load calculation that considers your home’s size, layout, insulation levels, window efficiency, local climate factors, and even the number of heat-generating appliances inside. An oversized unit will cycle too frequently and fail to remove humidity effectively, while an undersized system will run constantly without adequately cooling your space. Professional sizing ensures you get a system that maintains consistent comfort while operating efficiently.

For optimal performance and reliability, Ann Arbor homeowners should schedule professional air conditioning maintenance annually, ideally in spring before the cooling season begins. Systems that run year-round or face heavy use may benefit from twice-yearly service. Regular maintenance prevents unexpected breakdowns, extends equipment life, maintains energy efficiency, and preserves manufacturer warranty coverage. Our maintenance service includes a comprehensive inspection, cleaning, and adjustment of all critical components to ensure your cooling system performs at its best during hot weather.

Air conditioner freeze-ups in Ann Arbor homes typically result from restricted airflow or refrigerant issues. Clogged air filters, blocked return vents, closed supply registers, dirty evaporator coils, or damaged blower fans can all restrict airflow over the cooling coils, causing moisture to freeze instead of draining properly. Low refrigerant levels due to leaks can also cause freezing by creating abnormally low temperatures in the system. Regular maintenance prevents most freeze-ups by ensuring proper airflow and refrigerant levels, while prompt professional service when freezing occurs can prevent damage to your compressor and other expensive components.
