The Complete Guide to HVAC & Plumbing for Manufactured Homes

Why Manufactured Homes Require a Specialized Approach

Manufactured and mobile homes are an increasingly popular housing option across Southeast Georgia and the South Carolina Lowcountry. Offering affordability, quicker build times, and flexible design options, they present a practical solution for modern homebuyers. Yet, they come with their own set of HVAC and plumbing considerations that require thoughtful planning and experienced service.

Unlike traditional homes, manufactured homes are often constructed with:

  • Narrow or limited duct chases

  • Lower insulation ratings

  • Smaller or nonexistent mechanical rooms

  • Unique foundation styles like crawlspaces or pier and beam

These differences can lead to airflow problems, high humidity levels, inadequate heating or cooling, and plumbing inefficiencies. At Dyess Air & Plumbing, we specialize in systems built for the unique challenges and opportunities of manufactured homes. With more than four decades of regional experience, our team delivers personalized service and precision installation backed by proven reliability.

Understanding HVAC Needs in Manufactured Homes

Manufactured homes typically feature tighter structural footprints and less insulation than site-built homes. This makes heating and cooling systems work harder than necessary when improperly designed or sized. Our job is to match the best technology with the specific needs of your space and climate.

Common HVAC Challenges

  • Uneven Room Temperatures: Poor duct placement and size mismatch cause hot and cold spots throughout the home.

  • Energy Waste: Lower insulation and air leaks force HVAC systems to run longer, using more energy.

  • Excess Moisture: Without proper humidity control, mold and mildew can form.

  • Obsolete Units: Outdated systems lack the energy-saving capabilities and zoned control of modern alternatives.

When it comes to manufactured housing, correct system sizing and tailored ductwork layouts are crucial to comfort and cost control.

HVAC Systems That Work for Manufactured Homes

Ductless Mini-Split Systems

Mini-split systems are a powerful solution for homeowners seeking efficient, customizable heating and cooling. They are ideal for homes with no existing ductwork or where space is limited.

Advantages:

  • Independent temperature control for each zone

  • 30% to 40% more efficient than ducted systems

  • Whisper-quiet operation

  • Built-in dehumidification

  • Minimal impact during installation

Recommended Products:

  • Carrier Infinity® Ductless System – Smart sensors, low noise, and connected controls

  • Mitsubishi Electric MSZ-FS Series – Advanced inverter technology for year-round performance

Packaged HVAC Systems

Packaged units are excellent for manufactured homes with little or no indoor space for HVAC equipment. These all-in-one systems deliver consistent comfort from a compact outdoor setup.

Our Top Picks:

  • Carrier Performance™ Packaged Units – Durable, ENERGY STAR® rated, space-saving design

Smart Thermostats

Upgrade to a smart thermostat for increased comfort, convenience, and energy savings. These systems adapt to your lifestyle and give you full control from anywhere via mobile apps.

Customer Favorites:

  • ecobee Smart Thermostat for Carrier – Features geofencing, IAQ insights, and smart sensors

Plumbing Challenges in Manufactured Homes

Many older manufactured homes were built with plumbing materials and layouts that were affordable at the time but are no longer practical or safe by today’s standards. In addition, tight crawlspaces and complex routing make plumbing upgrades more challenging without the right experience.

Common Issues Include:

  • Polybutylene Pipes: Now obsolete due to their high failure rate over time

  • Low Water Pressure: Caused by mineral deposits or narrow supply lines

  • Hidden Leaks: Difficult-to-access fittings can allow water damage to go unnoticed

  • Undersized Water Heaters: Old tank models often can't meet current household needs

Addressing these issues proactively can prevent more serious and costly repairs in the future.

  • Carrier Performance™ Dehumidifiers: Quiet, ENERGY STAR® certified units with seamless HVAC integration

  • AprilAire E-Series Dehumidifiers: Ideal for managing humidity in coastal and high-moisture climates
