If your furnace turns on and off every few minutes, it's likely short-cycling—a common issue here that strains your system and hikes bills. This is often caused by a clogged air filter, incorrect thermostat placement, or a faulty flame sensor. For your safety and the furnace's longevity, we recommend turning the system off at the thermostat and calling our HVAC team. We'll diagnose the root cause, whether it's a simple cleaning or a component repair, to restore steady, efficient heat to your home.

Frozen coils are a frequent local problem, usually due to restricted airflow from dirty filters or blocked vents, or low refrigerant levels. When coils freeze, your system can't cool your home and may suffer serious damage. Our HVAC specialists perform thorough inspections to clean coils, check refrigerant charges, and ensure proper airflow throughout your ductwork. Regular maintenance with us helps prevent freezing, keeping your system running reliably through our humid summers and protecting your investment.

Absolutely. Many HVAC efficiency problems stem from home envelope issues, like poor insulation, leaky ductwork run under floors, or blocked return vents. Our unique combination of general contracting and HVAC expertise allows us to provide holistic solutions. We can assess if new flooring installation is affecting vent airflow, improve insulation in key areas, or properly seal and route ducts during a renovation. This integrated approach ensures your HVAC system works in harmony with your home's structure for optimal comfort and efficiency.
