When winter brings heavy snow and freezing temperatures, your heating system is your home's most critical appliance, standing between your family's comfort and the harsh mountain climate.

Upgrading your furnace is an investment in your home's safety, efficiency, and comfort. A new system provides peace of mind, consistent warmth, and substantial savings on your monthly energy costs, ensuring you can relax and enjoy your mountain home, no matter how low the temperature drops outside.
Signs It's Time to Replace Your Furnace
It’s easy to ignore the subtle signs of a failing furnace until a complete breakdown occurs on the coldest night of the year. Being proactive can save you from a frigid, inconvenient emergency. Pay close attention to your heating system and watch for these common indicators that a replacement is on the horizon:
Your Furnace is Over 15 Years Old
Even with diligent maintenance, the average furnace has a lifespan of 15 to 20 years. If your unit is approaching or has surpassed this age, it's operating on borrowed time. Older systems are significantly less efficient than modern models and are far more prone to breakdowns.
Steadily Rising Energy Bills
Have you noticed your heating bills climbing higher each winter, even though your usage hasn't changed? As a furnace ages, its components wear down, forcing it to work harder and consume more fuel to produce the same amount of heat. This decline in efficiency directly translates to higher utility costs.
Frequent and Costly Repairs
A repair call every few years is normal. However, if you find yourself scheduling service multiple times a season and the repair costs are adding up, it’s a clear sign that the system is failing. Investing more money into an old, inefficient unit is often not a wise financial decision when those funds could be applied to a new, reliable system.
Uneven Heating and Cold Spots
Is your living room cozy while your bedrooms feel chilly? An aging furnace often loses its ability to distribute air evenly throughout your home's ductwork. This results in inconsistent temperatures and persistent cold spots, diminishing your overall comfort.
Unusual Noises During Operation
Your furnace should operate with a relatively quiet hum. If you start hearing loud or persistent banging, rattling, squealing, or grinding sounds, it often indicates a serious mechanical problem with components like the blower motor or internal parts.
Visible Rust or Cracks
A physical inspection of your furnace can reveal a lot. If you see visible signs of rust, corrosion, or cracks on the unit's exterior or around its components, it could indicate a structural problem or a potential leak in the heat exchanger, which can release dangerous carbon monoxide.

Our Comprehensive Furnace Replacement Process
MCR Services Inc. understands that replacing a furnace is a significant undertaking. Our process is designed to be seamless, transparent, and tailored to the specific needs of your Mammoth Lakes home, ensuring you get the perfect system for lasting performance and efficiency:
In-Home Consultation and Load Calculation
A successful installation starts with a thorough assessment. We don't believe in one-size-fits-all solutions. Our expert technician will visit your home to evaluate your existing system, inspect your ductwork, and consider factors like your home's square footage, insulation levels, window quality, and ceiling height. We perform a detailed load calculation to determine the precise size and capacity of the furnace required to heat your space efficiently at high altitude, preventing issues like short-cycling or insufficient heating.
Selecting the Right High-Efficiency System
Based on our assessment, we will present you with a curated selection of high-efficiency furnace options that fit your home and budget. We'll walk you through the differences in AFUE (Annual Fuel Utilization Efficiency) ratings, explaining how a higher rating translates into greater energy savings. We’ll also discuss the different fuel types available to you, helping you make an informed decision that aligns with your long-term goals.
Professional, Code-Compliant Installation
Our certified installation team treats your home with respect and professionalism. On installation day, we will carefully remove and responsibly dispose of your old furnace. The new unit will be meticulously installed, ensuring all gas, electrical, and ventilation connections are secure and meet all local Mammoth Lakes building codes and safety standards. We take pride in our clean, precise workmanship.
System Commissioning and Homeowner Walkthrough
Once the furnace is installed, our job isn't finished. We perform a multi-point system commissioning process to test every function, calibrate the thermostat, and fine-tune the airflow to ensure it operates at peak performance and efficiency. We then provide you with a detailed walkthrough, showing you how to operate your new system and answering any questions you may have.
Fuel Types for Your Mountain Residence
The fuel source for your furnace is a key consideration. We have extensive experience installing and servicing all types of heating systems prevalent in the Eastern Sierra:
- Natural Gas Furnaces: Where available, natural gas is typically the most affordable and convenient fuel source. Modern gas furnaces offer exceptional efficiency and powerful heating performance.
- Propane (LP) Furnaces: For homes without access to a natural gas line, propane is a powerful and reliable alternative. High-efficiency propane furnaces provide robust heating capabilities, making them an excellent choice for our cold climate.
- Electric Furnaces: While their operating costs can be higher, electric furnaces offer a lower upfront installation cost and are known for their durability and safety. They are often paired with a heat pump to create a highly efficient dual-fuel system.
Flexible Financing to Fit Your Budget
We believe every family in Mammoth Lakes deserves a safe and reliable heating system. A new furnace is a critical home investment, and we are committed to making it accessible. We offer a variety of flexible financing options designed to help you manage the cost of your new system without straining your budget. Investing in a high-efficiency furnace now will pay dividends for years to come through lower energy bills and enhanced home comfort.
