Core offerings (installation, repair, maintenance, indoor air quality)

• Installation: Full-system installations including high-efficiency furnaces, air conditioners, heat pumps, geothermal systems, VRV/VRF solutions, and ductless mini-splits. We design systems to match building loads and available space.
• Repair: Rapid diagnostics and repair for compressors, heat exchangers, control systems, ductwork, and custom sheet metal components. Repairs focus on restoring safe operation and preventing repeat failures.
• Maintenance: Planned maintenance and seasonal tune-ups, filter service, lubrication, refrigerant checks, safety tests, and system balancing to extend equipment life and reduce energy bills.
• Indoor Air Quality (IAQ): Air purification, UV lights, humidifiers and dehumidification, cottonwood/pollen filtration, duct cleaning, and zoning controls to reduce allergens and improve occupant health.

Common HVAC issues in Mehlville and why they occur

• High cooling load and humidity problems during hot summers, causing short-cycling, poor dehumidification, and mold growth on coils and in ductwork.
• Allergens and cottonwood pollen that rapidly clog filters and reduce airflow, worsening comfort and indoor air quality.
• Aging furnaces and heat pumps subjected to frequent temperature swings in Missouri winters, raising the risk of heat exchanger or compressor failure.
• Leaky or undersized duct systems in older homes that create hot/cold spots, reduce efficiency, and circulate dust and contaminants.
• Storm or wind damage to outdoor units and rooftop equipment, requiring sheet metal repair or replacement.

How we diagnose HVAC problems in Mehlville

Diagnostics begin with a thorough, on-site evaluation to determine underlying causes, not just symptoms:

• Visual inspection of indoor and outdoor equipment, controls, and sheet metal components.
• System performance checks: airflow measurement, refrigerant pressure, electrical load, combustion safety, and thermostat calibration.
• Duct assessment and leak testing when comfort or efficiency problems suggest air loss.
• Indoor air quality testing when occupants report allergies, odors, or respiratory symptoms.
• Load calculations and building envelope review for replacement or upgrade projects.

Diagnostics are followed by a clear plan that outlines priority repairs, recommended upgrades, estimated timelines, and expected performance improvements. Union-trained technicians and experienced sheet metal fabricators ensure both mechanical and ductwork solutions are executed to professional standards.

Typical repairs and long-lasting solutions

• Refrigeration circuit repairs and compressor replacement to restore cooling capacity and efficiency.
• Heat exchanger and burner service for safe, reliable heating.
• Duct sealing, insulation, and custom-fabricated transitions to eliminate leaks and balance airflow.
• Replacement or retrofit with high-efficiency systems (geothermal, VRV/VRF, ECM blowers) to reduce energy use and improve comfort.
• Upgrades to controls: programmable Wi-Fi thermostats, zoning systems, and energy-saving control strategies to match actual building use.
• IAQ installs such as whole-home purifiers, UV lights for microbial control, and humidification systems to improve winter comfort.

Each solution is selected to address the root cause, improve indoor comfort, and deliver predictable energy savings over the life of the equipment.

Planned maintenance and energy-saving strategies for Mehlville properties

Regular maintenance prevents emergency failures and reduces operating costs. Typical maintenance plans for Mehlville include:

• Semi-annual tune-ups (heating and cooling seasons) with safety and efficiency checks
• Scheduled filter replacement or upgraded filtration during pollen season
• Duct cleaning and inspection every few years or when IAQ testing indicates issues
• Seasonal checks of outdoor units and roof-mounted equipment after storms
• Implementation of zoning or variable-speed systems where homes have multiple temperature zones

Energy-saving strategies tailored to local conditions include right-sizing equipment with accurate load calculations, improving ductwork and insulation, installing programmable thermostats, and considering geothermal or VRV systems for buildings with high efficiency goals.
