Common HVAC Problems

You rely heavily on your heater and air conditioner to keep your home comfortable year-round, so it is important to be able to recognize when something is wrong with your system.

If you notice any of the following problems, call our Somerset heating and air conditioning technicians:

  • Your heater is blowing cold air
  • Your AC is blowing warm air
  • There are funky smells coming from your ducts
  • Your monthly energy bills are through the roof

  • Your home never seems to reach the temperature set on your thermostat

Does My Home Need Surge Protection?

Every day, the appliances in your home are at risk from voltage spikes and surges that can take place at any time. These increases in voltage can be caused by lightning, faulty wiring, problems with the utility company’s equipment, and more. Most often, however, these surges are caused by the operation of high power devices in your home such as your heater, air conditioner, or refrigerator. Without surge protection, these surges are sent directly to the devices in your home, which can damage or destroy these devices, and even start a fire. A surge protector automatically detects and diverts surges before they have a chance to damage your appliances and put your home at risk.

If you are interested in whole-home surge protection, reach out to our Somerset electricians today.
