Seasonal HVAC tips for Lawrenceville homeowners
Spring
Schedule an AC tune-up before the first Lawrenceville heat wave. Cleaning coils and checking refrigerant now prevents mid-summer breakdowns.
Summer
Change filters monthly during peak cooling. If your AC runs constantly but the house stays warm, call us — that's usually low refrigerant or a failing compressor.
Fall
Book a furnace or boiler inspection before temperatures drop. We check heat exchangers, ignition and carbon-monoxide safety on every Lawrenceville heating visit.
Winter
Keep vents clear of snow and furniture. No heat? Check the thermostat batteries and breaker first — then call us any time, day or night.
