S & S Mechanical Heating & Cooling | Certified HVAC Repair in Howell, MI

Short cycling is a common issue here, often caused by a dirty air filter restricting airflow, a faulty flame sensor, or an incorrectly sized furnace for your home. It strains your system and increases bills. Our technicians perform a thorough diagnostic to pinpoint the exact cause—from checking thermostat placement to assessing ductwork—and provide a reliable repair to restore normal, efficient operation.

Signs include uneven heating/cooling, dusty rooms, high energy bills, and weak airflow from vents. In Howell, temperature extremes make duct leaks especially wasteful, as conditioned air escapes into unconditioned spaces like attics. We perform professional duct testing to locate leaks and use industry-best practices to seal them, improving your comfort and reducing energy waste by keeping the air you pay for inside your living spaces.

Absolutely. A short-cycling furnace wastes energy starting up repeatedly, while duct leaks can lose 20-30% of your conditioned air. By repairing these issues common in Howell homes, we help your HVAC system run as designed—longer, steadier cycles and efficient air delivery. This reduces strain on the equipment and can lead to noticeable savings on your monthly energy bills, making the repair a smart investment in your home's efficiency.
