When your heating or cooling system fails, especially with Mammoth Lakes' demanding climate, you need more than a quick fix—you need a reliable, expert solution that restores comfort and peace of mind. A malfunctioning furnace during a winter storm or a broken air conditioner during a summer heatwave isn't just an inconvenience; it's a critical issue that affects your home's safety and your family's well-being. We provide comprehensive HVAC repair services designed to address any system failure with precision and speed, ensuring your home remains a comfortable sanctuary year-round.
At MCR Services Inc., our technicians are not just repair specialists; they are highly trained professionals with deep expertise in the unique challenges that Mammoth Lakes' environment presents to HVAC systems. We understand how extreme temperature swings, high altitude, and dry air can impact your equipment, and we bring this localized knowledge to every diagnostic and repair job.
Our Comprehensive HVAC Repair Services
Your home’s comfort system is complex, with many interconnected parts. Our team is equipped to handle issues across the entire spectrum of HVAC equipment, regardless of brand or model. We are your single source for all heating and cooling repairs.

Furnace Repair
A reliable furnace is non-negotiable in Mammoth Lakes. If you're experiencing issues like a pilot light that won't stay lit, strange rumbling or screeching noises, a blower that runs constantly, or simply insufficient heat, we can help. Our technicians will diagnose the root cause, whether it's a faulty ignitor, a malfunctioning thermostat, a cracked heat exchanger, or a clogged filter, and perform the necessary repairs to restore warmth and safety to your home.
Air Conditioning Repair
When summer temperatures rise, a functional AC is essential. We address all common air conditioning problems, including systems that blow warm air, refrigerant leaks, frozen evaporator coils, and faulty compressors. We’ll get your system running efficiently again, so you can escape the heat and enjoy a cool, comfortable indoor environment.
Heat Pump Repair
Heat pumps are an efficient year-round solution, but they can experience unique issues, such as getting stuck in heating or cooling mode or failing to defrost during winter. Our experts understand the intricacies of heat pump technology and can quickly resolve any problem to ensure consistent, year-round performance.
Ductless Mini-Split Repair
From single-zone to multi-zone systems, we service and repair all types of ductless mini-splits. Whether you're dealing with a unit that's leaking water, not responding to the remote, or making unusual noises, MCR Services Inc. has the tools and experience to get it back in working order.
Our Diagnostic Process: Identifying the Real Problem
A successful repair starts with an accurate diagnosis. We don't believe in guesswork. When our technician arrives at your Mammoth Lakes home, they follow a meticulous process to pinpoint the exact cause of the failure.
This typically involves:
- System Consultation: We listen to you describe the symptoms you've noticed, such as strange noises, odors, or performance issues.
- Visual Inspection: We thoroughly examine the indoor and outdoor units, checking for obvious signs of damage, leaks, or blockages.
- Component Testing: Using advanced diagnostic tools, we test key electrical components, including capacitors, contactors, and motors, to ensure they are functioning correctly.
- System Performance Analysis: We check thermostat calibration, measure refrigerant levels, and assess airflow to identify performance-related problems.
This detailed approach ensures MCR Services Inc. fixes the problem correctly the first time, saving you time, money, and future frustration.
Repair or Replace? Making an Informed Decision
One of the most common questions homeowners face is whether to repair an aging HVAC system or invest in a new one. We provide honest, transparent advice to help you make the best choice for your home and budget.
We often use a simple guideline: multiply the age of your unit by the estimated cost of the repair. If the total exceeds $5,000, replacement is often the more financially sound long-term option.
Consider Repairing If:
- Age: Your system is less than 10–12 years old.
- Repair Type: The required repair is relatively minor and inexpensive.
- Condition: The unit has been well-maintained and is still energy-efficient.
Consider Replacing If:
- Age: Your system is over 15 years old.
- Repair Frequency: You are facing frequent and costly repairs.
- Energy Bills: Your energy bills have been steadily increasing.
- Major Failures: The repair is major, such as a failed compressor or heat exchanger.
Preventing Future Breakdowns with Proactive Maintenance
The best way to avoid emergency repairs is through regular, professional maintenance. In Mammoth Lakes, where HVAC systems work hard against the elements, preventative care is even more critical.
Annual tune-ups help:
- Identify and resolve minor issues before they become major failures.
- Improve energy efficiency.
- Extend the lifespan of your equipment.
- Ensure your system is ready to handle the peak demands of winter and summer.
