HVAC Repair FAQs in Lawrenceville, NJ

Yes. A blank thermostat usually means a blown fuse in the air handler, tripped breaker, or dead batteries. We can diagnose electrical issues and replace the thermostat if necessary to restore communication with your system.
If your system is relatively new and the issue is minor—such as a bad capacitor or contactor—repairing is highly cost-effective. However, if the unit is over 10-15 years old, uses outdated R-22 refrigerant, or requires frequent expensive repairs, replacement is your best option.
Warm air from your AC in Lawrenceville, NJ is usually caused by low refrigerant levels, a dirty evaporator coil, or a failing compressor. A quick inspection and diagnostic by Local HVAC Repair Masters will identify the issue and get your home cooling again.
A well-maintained air conditioning unit typically lasts 10 to 15 years, while a gas furnace can last 15 to 20 years. Regular annual tune-ups are key to maximizing the lifespan of your equipment.
First, check the air filter. If it is clean, your system is likely low on refrigerant or the evaporator coil is frozen solid. Turn the AC off to prevent compressor damage, and call (877) 515-4832 so we can send a technician to Lawrenceville, NJ to inspect it.
