Your #1 Choice for Furnace Installation in Marietta, PA

Replacing or installing a new furnace is a smart investment in your home’s winter comfort, energy efficiency, and long-term reliability. Our expert HVAC technicians install high-performance heating systems designed to keep your home warm while reducing energy costs.

Signs You Need a New Furnace

A furnace that’s nearing the end of its lifespan may show warning signs that it’s time for a replacement. Here are some of the most common indicators:

  • Your Furnace is Over 15 Years Old: Most furnaces last 15–20 years. Older models become less efficient and require frequent repairs. Upgrading to a high-efficiency model can reduce heating costs significantly.
  • Rising Energy Bills: An aging furnace works harder to heat your home, leading to increased energy usage. A new system can lower monthly heating costs by up to 30%.
  • Frequent Breakdowns & Expensive Repairs: If you’re calling for repairs multiple times a season, it may be more cost-effective to replace the system.
  • Uneven Heating & Cold Spots: Inconsistent temperatures between rooms often mean your furnace is no longer distributing heat properly.
  • Strange Noises or Unusual Odors: Banging, rattling, squealing, or burning smells could indicate serious mechanical issues or system wear.

If you’re experiencing any of these problems, 717 Mechanical LLC can help you choose and install a reliable, energy-efficient furnace for your home.

Choosing the Right Furnace for Your Home

Selecting the right furnace is essential for efficiency, comfort, and long-term savings. Our team at 717 Mechanical LLC helps you find the best system based on:

Fuel Type: Gas, Electric, or Oil?

  • Gas Furnaces – The most common choice, offering high efficiency and lower heating bills.
  • Electric Furnaces – Ideal for homes without natural gas but higher in long-term energy costs.
  • Oil Furnaces – Effective in very cold climates, though less common in modern homes.

Furnace Efficiency Ratings (AFUE)

  • AFUE (Annual Fuel Utilization Efficiency) measures how efficiently fuel is turned into heat.
  • High-efficiency furnaces (90%+ AFUE) offer lower energy waste and higher performance.
  • Standard-efficiency models (80–89% AFUE) provide reliable, cost-effective heating.

Furnace Size & Heating Capacity

  • Proper sizing is critical—a furnace that's too large or too small can cause inefficiency and wear.
  • We perform a detailed load calculation to ensure your home gets the right-sized furnace for optimal comfort.

By selecting the right furnace, you’ll enjoy better performance, reduced energy costs, and long-term heating reliability.
