Who We Are & Why We Specialize in Manufactured Homes

Since 1963, Master Mobile Home Service Inc has been Blaine and the greater Twin Cities area’s trusted HVAC contractor specializing in manufactured home systems. Our family-run company focuses exclusively on the unique heating, ventilation, air conditioning, and gas needs of manufactured and mobile homes.


With decades of hands-on experience, our technicians understand how manufactured home construction differs from site-built homes—different duct runs, constrained access, specialized furnace models, and unique venting and gas connections. We deliver practical, long-lasting HVAC solutions that keep your home comfortable, safe, energy-efficient, and code-compliant throughout Minnesota’s shifting seasons.

Why you need a specialist for your initial gas hookup

Manufactured homes require specific piping configurations, specialized flexible connectors, and precise routing to accommodate potential ground settling. A general contractor might not know the exact mobile home codes for Blaine, MN. By hiring specialists for your meter-to-home connection, you guarantee that your foundational gas supply is installed perfectly the first time.

Why proper sizing and system selection matter for manufactured homes

Many problems with manufactured-home HVAC stem from incorrect equipment sizing or misapplied installation practices. Oversized equipment can short-cycle, increasing wear while failing to control humidity. Undersized systems struggle to reach setpoints and run continuously, shortening component life. Ducting in manufactured homes can introduce higher static pressure or uneven airflow if transitions and registers are not adjusted correctly. Master Mobile Home Service Inc evaluates your home’s square footage, insulation levels, duct layout, and occupancy patterns to recommend a system that balances runtime, energy efficiency, and comfort year-round.

Safety and compliance are non-negotiable

Gas safety and proper venting are core competencies for us. Our technicians test for gas leaks, verify regulator performance, inspect venting and combustion air, and perform carbon monoxide checks when applicable. We adhere to local codes and manufacturer requirements to ensure the system not only works but does so safely. We document completed work and provide recommendations to keep your home compliant and secure.

Common situations we handle

Furnace won’t start or cycles frequently.
Insufficient heating or cooling, uneven rooms.
Strange noises from furnace or ducting: rattles, clanks, or whistling.
Pilot light issues or ignition failures.
AC short-cycling or poor cooling on hot days.
Water heater leaks, slow recovery, or lack of hot water.
Gas odor, suspected leaks, or low pressure concerns.
Seasonal tune-up requirements and pre-winter or pre-summer checks.

Preventive maintenance—an investment that pays off

Regular maintenance can prevent sudden failures, improve efficiency, and reduce repair costs over time. Our maintenance includes filter changes, safety checks, blower cleaning, coil inspection, thermostat calibration, burner servicing, flue checks, and system performance testing.


For manufactured homes that often have compact HVAC footprints, maintenance prevents dirt buildup, overheating, and mechanical stress caused by restricted airflow.

Energy-saving upgrades and recommendations

We advise on practical upgrades like programmable thermostats, improved filtration, and zoning adjustments to maximize comfort and reduce energy use.


For many manufactured homes, small investments in sealing and tuning the system offer measurable savings and better indoor comfort without the need for full replacement.

Frequently Asked Questions

  • How often should I service my manufactured home furnace?

    Annual service, preferably before winter, keeps your furnace safe and reliable. Furnaces in mobile homes face seasonal load shifts, so pre-season checks are critical.

  • Can you replace a manufactured home furnace with a site- built home furnace?

    No. Furnaces must be approved for installation into a manufactured home.

  • What if I smell gas?

    Call your gas supplier immediately.

  • Do you offer financing for replacements?

    We work with customers to outline affordable options.

  • Are your technicians insured?
