24/7 Emergency Furnace Repair

At Len The Plumber Heating & Air, your safety is our priority. We understand the urgency of addressing furnace malfunctions, especially when they pose potential dangers like carbon monoxide leaks, fire hazards, and poor air quality.

That’s why we provide reliable heating repairs. Our dedicated team is on standby 24/7 to respond to emergencies, ensuring a prompt resolution to restore your home’s safety and comfort.

Signs you need furnace repair include:

  • Unusual noises: Banging, clanging, and squealing are indicators that your furnace may have mechanical issues.
  • An irregular pilot light: Your furnace flame should be blue. A yellow or flickering flame could signal combustion issues and carbon monoxide buildup.
  • Weak or no heat output: Insufficient heating often indicates issues with the heating element, pilot light, or other critical components.
  • Unresponsive controls: Difficulty turning your furnace on or off may be an electrical or thermostat issue.

Furnace Installation & Replacement for Northern Virginia Homes

Maximize your home’s comfort and safety with professional heating installation and replacement.

Furnaces become less efficient and more prone to breakdowns as they age. Proactive replacement before a complete breakdown ensures uninterrupted heating and allows you to upgrade to a more energy-efficient model.

Our furnace replacement process ensures a seamless service experience. Here’s what you can expect:

  • System assessment: We’ll inspect your current unit to determine if replacement is the best option.
  • System selection: We provide personalized system recommendations, considering your home size, budget, and efficiency goals.
  • Removal of your current unit: We’ll disconnect and safely dispose of your old furnace.
  • Installation: Our skilled technicians will place your new system and ensure proper electrical and fuel connections.
  • Testing: We’ll run a test cycle to ensure optimal furnace operation.

Gas vs. Electric Furnaces

While electric and gas furnaces are both popular choices, here’s how they compare:

  • Installation cost: Gas furnaces often cost more to buy and install than electric furnaces.
  • Operation cost: Electricity costs more than natural gas in Northern Virginia, resulting in higher utility bills.
  • System life span: Gas furnaces have a life span of 15 to 20 years, while electric furnaces may last for 20 years or more.
  • Maintenance: Both systems require annual maintenance to ensure superior performance during the cold season.
  • Safety: Gas furnaces produce carbon monoxide because the system combusts fuel. While they’re safe if regularly maintained, electric furnaces are ultimately safer.
  • Energy efficiency: Electric furnaces are the most environmentally friendly option because they use an electric heating element instead of the fuel combustion required by gas furnaces.

Frequently Asked Questions

Are furnaces energy-efficient?

Furnaces vary in energy efficiency. While they are generally less efficient than heat pumps, you can still have affordable utility bills, especially with the low cost of gas.

Electric furnaces achieve 100% AFUE as there’s no combustion, while for gas furnaces, a minimum of 81% AFUE is required, but 90% or higher is recommended for optimal efficiency.

What are the benefits of replacing your furnace?

New furnaces are compatible with smart and programmable thermostats, allowing homeowners to take advantage of their energy usage.

With added benefits like improved energy efficiency, cost-effective operation, and enhanced comfort, homeowners can seamlessly integrate their heating systems into their daily lives.

Why does my furnace keep shutting off?

A wide spectrum of system issues, including dirty air filters, pilot light issues, tripped breakers, or a blocked heat exchanger, can cause furnace short-cycling.
