Common Questions
My AC just quit on a hot day in Sylvan Township. How fast can a tech get here?
A technician can typically be en route within 15-25 minutes. Our service area covers the Chelsea-Dexter Corridor, and we monitor I-94 for real-time traffic to optimize routing. For a no-cool emergency, we prioritize same-day dispatch to restore comfort and prevent secondary issues like humidity damage in your home.
Should I consider a heat pump instead of my gas furnace?
For Sylvan homes, a dual-fuel system pairing a heat pump with your existing gas furnace is often optimal. The heat pump handles moderate cooling and heating efficiently, especially during off-peak hours outside DTE's 2-7 PM window. The gas furnace provides reliable heat during winter lows, ensuring comfort when heat pump efficiency declines. This strategy maximizes the utility rebate and federal tax credits while reducing overall operating costs.
Is it worth replacing my old unit just to meet the new SEER2 standard?
The 2026 federal minimum is 13.4 SEER2, but modern systems often reach 16-18 SEER2. At Sylvan's average rate of $0.18/kWh, upgrading from a 10 SEER unit can cut cooling costs by over 30%. The active Inflation Reduction Act rebates, with caps up to $8,000, significantly offset the initial investment, making the payback period for high-efficiency models very favorable.
Why does my AC struggle on the hottest few days each summer?
Michigan's humid continental climate can push temperatures above the standard 88°F design temperature used for sizing most residential systems. When outdoor temps exceed this limit, the system's capacity drops and it runs continuously to try to meet the load. Modern units using R-454B refrigerant maintain better efficiency and capacity at these higher temperatures compared to older R-410A systems, narrowing this performance gap.
What are the rules for installing a new AC with the latest refrigerant?
All installations in Washtenaw County require a permit from the Washtenaw County Building Department. As of 2026, systems using A2L refrigerants like R-454B must comply with updated safety standards (UL 60335-2-40). This mandates leak detection systems, specific room size requirements, and revised service practices. Only EPA-certified technicians with A2L-specific training can legally handle the refrigerant and install the equipment.
Why does my old air conditioner keep freezing up?
Systems in Sylvan built around 1955 are now 70+ years old. The original galvanized steel ductwork and insulation degrade over time, allowing more moisture into the system. This excess humidity, combined with low refrigerant charge from slow leaks in aged coils, causes the evaporator coil temperature to drop below freezing. That leads directly to the common condensate line freezing failure, blocking drainage and shutting down cooling.
Can my home's ducts handle a better air filter for ozone and pollen?
Sylvan's May pollen peak and summer ozone risk make MERV-13 filtration desirable. Your existing galvanized steel ductwork is robust, but its original design may not account for the higher static pressure of advanced filters. A technician should measure static pressure and assess duct integrity; often, sealing leaks or modifying the return air plenum is necessary to prevent airflow restriction and maintain system performance.
My Ecobee thermostat is showing an E4 alert. What does that mean?
An Ecobee E4 code indicates a loss of communication with the outdoor AC or heat pump unit. In Sylvan, this often points to a tripped high-pressure switch, a faulty control board, or a wiring issue exacerbated by temperature swings. It's a protective alert that prevents system operation. A technician will diagnose the specific fault—common culprits include a dirty condenser coil or a refrigerant overcharge—to restore communication and prevent compressor damage.
