Frequently Asked Questions
I keep hearing about new efficiency rules. What do the 2026 SEER2 standards mean for my utility bills?
As of January 2026, all new central AC systems installed in Michigan must meet a minimum 13.8 SEER2 rating. This federal mandate ensures new equipment uses significantly less electricity than your older model. With DTE Energy rates at $0.18 per kWh, upgrading to a 16+ SEER2 unit can cut your cooling costs by over 20%. The active Inflation Reduction Act rebates, with an $8,000 cap, can directly offset this higher-efficiency investment, improving your payback period.
Given the cost of propane, is switching to a heat pump a practical idea for Sanilac winters?
Modern cold-climate heat pumps are engineered to operate efficiently in Michigan winters, making them a viable primary heat source. Pairing one with your existing propane furnace as a dual-fuel system is often the most cost-effective and reliable solution for Sanilac. This setup uses the heat pump during milder weather and the propane system during extreme cold snaps below its balance point. Strategically, the heat pump can avoid operation during DTE's peak hours from 2 PM to 7 PM to maximize savings, leveraging the Inflation Reduction Act rebates for the installation.
What are the legal and safety requirements for installing a new AC system in Sanilac County now?
All installations require a permit from the Sanilac County Building Department, which ensures compliance with Michigan mechanical and electrical codes. As of 2026, new systems using A2L refrigerants like R-454B must adhere to updated UL 60335-2-40 safety standards, which mandate specific leak detection, room size calculations, and service access protocols. Hiring a licensed contractor who is EPA 608 certified for these refrigerants is not just recommended; it's a legal necessity for a safe and code-compliant installation that will pass final inspection.
With spring pollen and general particulate matter, can my current ducts handle a better air filter?
Sanilac's moderately humid climate and May pollen peak make advanced filtration valuable for indoor air quality. Your existing galvanized sheet metal ductwork is generally robust enough to handle a MERV-13 filter without causing excessive static pressure, provided the system is properly sized and the ducts are sealed. We would measure the external static pressure during a service visit to confirm. This upgrade traps finer particulates that standard filters miss, protecting the blower motor and improving overall air cleanliness.
My furnace is as old as my house in Sanilac. Should I be worried about it failing soon?
A system installed in a home built around 1973 is now approximately 53 years old, which is well beyond its expected service life. In Downtown Sanilac, this age correlates directly with the common failure point of frozen evaporator coils. Older systems develop refrigerant leaks and airflow restrictions over decades, causing the coil to ice over and stop cooling. Proactive replacement avoids the high cost of repairing obsolete parts on a unit that may fail during our next heatwave.
My Ecobee thermostat just showed an 'E1' alert. What does that mean and what should I do next?
An Ecobee E1 error code specifically indicates the thermostat has lost communication with the outdoor AC or heat pump unit. In Sanilac, this often points to a tripped high-pressure switch, a failed control board, or a wiring issue exacerbated by seasonal temperature swings. First, check your outdoor unit's disconnect switch and circuit breaker. If those are intact, the system requires professional diagnosis. Continuing to reset it can risk compressor damage, so scheduling a service call is the recommended next step.
Why does my AC seem to struggle on the hottest afternoons we get here?
HVAC systems are sized based on a calculated design temperature, which for this region is 86°F. When ambient temperatures exceed this limit, as they occasionally do, the system must run continuously to maintain setpoint, reducing its ability to dehumidify and making the house feel less comfortable. The newer R-454B refrigerant, now standard in 2026, offers slightly better capacity retention at these higher temperatures compared to older R-410A, improving performance during peak heat events.
If my AC stops working on a hot day near the Sanilac County Courthouse, how fast can someone get here?
A technician can typically be dispatched from our local shop within 5 to 10 minutes for an emergency no-cool call. Our proximity to M-25 allows for quick routing throughout Downtown Sanilac, bypassing any local traffic delays. We prioritize these calls to prevent indoor temperatures from rising rapidly, which can strain an already failing system further. You'll receive a confirmed ETA before we leave the shop.
