Southwest Heating & Air | Experienced HVAC Repair in Carthage, MO

In Carthage's climate, a frozen evaporator coil is often caused by restricted airflow from a dirty filter, low refrigerant levels, or a failing blower motor. Our technicians perform a thorough diagnosis to pinpoint the exact cause. We then provide the necessary repair, such as sealing a refrigerant leak or replacing a faulty component, and offer guidance on proper maintenance to prevent future freeze-ups and protect your system.

Uneven cooling is frequently due to ductwork issues, an improperly sized HVAC system, or blocked vents. Southwest Heating & Air conducts detailed assessments of your home's airflow and duct integrity. We offer solutions like duct sealing, balancing, or system zoning recommendations to ensure conditioned air is distributed effectively to every room, eliminating hot and cold spots for consistent comfort.

We recommend professional maintenance at least twice a year—once before the cooling season and once before heating season. This proactive service is crucial for our local climate. It allows our technicians to clean critical components, check refrigerant levels, ensure electrical connections are tight, and catch small issues before they lead to major problems like coil freeze-ups or system failures, saving you money and hassle.
