Should I Repair or Replace My HVAC System?

If your furnace or AC is acting up, you are probably wondering what the best solution might be.

Consider the following factors when deciding whether to repair or replace your HVAC system:

  • Age of system: Unless the problem is severe, a younger system will probably not need to be replaced. However, if your system is acting up towards the end of its life expectancy (10-15 years for ACs and 15-20 years for furnaces), then you should consider replacing it.
  • Overall condition of system: A system that requires frequent repairs, wastes a ton of energy, and is poorly maintained should be replaced before it crashes for good. On the other hand, a system that hardly ever requires repairs, is energy efficient, and is well taken care of will probably just need to be repaired.
  • Your comfort: Your comfort matters. If your system consistently fails to meet your family’s comfort needs, it’s time to start looking for an upgrade.

For help assessing the condition of your system and deciding whether it should be repaired or replaced, turn to Guaranteed Service’s Flagtown heating and cooling professionals.

How Often Should I Schedule an Electrical Inspection?

Your electrical system is responsible for distributing electricity throughout your home to each of your appliances. To ensure it works safely and effectively, it is important that you stay on top of electrical inspections. Homeowners should schedule an inspection every 3-5 years, depending on the age of the home. Homes that are more than 40 years old or older should be inspected more often for safety reasons.

And, of course, if you are dealing with electrical problems—such as buzzing lights, hot outlets or switches, gnawed wires, power surges, or frequently tripped circuit breakers—you should schedule an inspection right away. Our Flagtown electricians offer the most detailed, comprehensive inspections in town!

Signs You Need to Call a Plumber

Your family relies heavily on your plumbing system day in and day out, so the last thing you need to deal with is a plumbing disaster. In order to keep your system taken care of, it is important to bring in a plumber as soon as you detect a problem.

Signs you need to call a Flagtown plumber include:

  • Slow or clogged drains
  • Running toilets
  • Unexplained puddles of water
  • No hot water
  • Leaking water heater
  • Foul-smelling drains
  • An unexpected spike in the water bill
  • Water that has an odd taste, scent, or appearance
  • Low water pressure
  • Frequently clogged or overflowing toilets
  • The sound of running water when no appliances are in use
  • No running water
  • Sweating water heater
  • Dripping faucets
