Signs You Need HVAC Repair

Inability reach thermostat setpoint – In exceptionally hot or exceptionally cold weather you may fall short of the desired temperature, but otherwise this is a cause for service.
Strange sounds & smells – Your HVAC system should not emit odors, loud sounds, or vibrations…all red flags. Smells can come from mold growth, a bad motor, faulty wiring, or an oil leak. Noises can have several causes including poor ignition, clogged filters, damaged fan blades and more
Poor airflow – This can indicate a minor issue or a more serious problem. You should first check your filter. If the poor airflow persists, then we will inspect your fan system and ductwork, as well as the refrigerant charge (see frozen coil on Cooling page!)
Increased energy bills – If your heating or cooling bill has been steadily increasing without explanation, then you should have your HVAC system checked. A change in your HVAC system’s efficiency probably indicates that there’s something wrong. Call us for a professional inspection so we can pinpoint the exact problem.
Water leak – The source may be the water heater, boiler piping, a condensing furnace, the air conditioning drains, or a humidifier. Regardless of the source, we can identify and fix the problem.
