Signs You Need HVAC Repair

Your heating and cooling systems are responsible for keeping your family comfortable all year long. When something is wrong with one of your systems, you need fast, reliable service. Ignoring even the smallest of problems with your heater or air conditioner can cause a lot of damage to your system down the line.

Schedule a Somerville HVAC repair if:

  • Your heater is blowing cold air
  • Your AC is blowing warm air
  • Your monthly energy bills are through the roof
  • There is an excessive amount of dust around your home
  • Your HVAC system is making loud, unusual sounds during operation
  • There are funky smells coming from your air vents
  • Your airflow is extremely weak
  • Your thermostat isn’t working
  • Certain rooms or areas of your home are never warm or cool enough
  • The temperature in your home never seems to reach the number set on your thermostat

No matter the problem, you can count on our technicians to offer a sound solution.

Is Something Wrong with My Sewer Line?

Your sewer line is responsible for safely transporting wastewater out and away from your home to protect your family and property. When something is wrong with it, you can be left with a lot of damage to repair. However, because your sewer line is in the ground, it can be difficult to determine when it is damaged.

To help make things easier for you, we’ve broken down the signs that your sewer line is in need of repair. They include:

  • There are gurgling or bubbling sounds coming from your drains
  • One or more of your sink or shower drains is slow or clogged
  • Your toilet frequently clogs or overflows
  • There is an unexplained patch of extra-green grass in your lawn
  • There are foul odors coming from one or more of your drains

Our Somerville plumbers are here to make sure your plumbing system is taken care of. Simply reach out to us today to make an appointment.

Should I Call an Electrician?

Because electrical systems can be very dangerous when mishandled, you should never try to take care of electrical services on your own. Making a mistake with electrical work can lead to serious injuries, fires, explosions, or even death. At Guaranteed Service, our Somerville electricians have extensive experience working with electrical systems and can handle any service you may need. The moment you suspect that something is wrong with your system, reach out to us and we will conduct a careful inspection, locate the source of the problem, and implement a safe, effective solution.

Signs that you need to call an electrician include:

  • Your lights are buzzing or flickering
  • Your outlets are burnt or smoking
  • You receive an electrical shock anytime you plug or unplug certain appliances
  • You have switches that don’t appear to do anything
  • Your family relies on a lot of power strips and extension cords to power your appliances
  • Your circuit breaker trips when you run too many appliances at once
  • Your outlet is extra hot
  • You can hear buzzing sounds behind your walls
