G & J Heating & Cooling | Top-Rated HVAC Services in Novi, MI

First, check that your thermostat is set to 'heat' and that the circuit breaker hasn't tripped. If those are fine, it's best to call a professional immediately to prevent further damage and get your heat restored. At G & J Heating & Cooling, we offer emergency service for Novi homeowners to diagnose and repair boiler issues like failed ignitors, circulator pump problems, or low water pressure, getting your home warm again as quickly as possible.

Frozen HVAC components are often caused by restricted airflow or low refrigerant levels. In our Novi climate, this can happen when air filters are clogged, vents are blocked, or there's a refrigerant leak. It's a serious issue that can damage your compressor. We recommend turning the system off and calling us. Our technicians will safely thaw the system, identify the root cause—such as a dirty evaporator coil or a leak—and perform the necessary repair to prevent recurrence.

Watch for unusual noises (banging, squealing), uneven heating or cooling in different rooms, a sudden spike in your energy bills, or frequent cycling on and off. In Novi, paying attention to these warnings before the deep winter sets in can help you avoid a full system breakdown during the coldest weather. We provide thorough inspections and proactive repairs to address these early signs, ensuring your system is reliable when you need it most.
