Harms Heating & Cooling - Aberdeen's Licensed HVAC Repair

As your comprehensive local HVAC provider, we handle a full range of services to maintain your home's comfort. This includes installation, repair, and maintenance for furnaces, air conditioners, and heat pumps. Our goal is to be the only company you need to call, ensuring your system operates reliably through every South Dakota season with quality work and attentive service.

Frozen components on a heat pump are a frequent issue in our climate, often caused by dirty filters, low refrigerant, or airflow problems. We diagnose the specific cause—whether it's a simple cleaning or a more complex repair—to get your system thawed and running efficiently again, helping you avoid further damage and restore consistent heating.

High heating bills often stem from an aging furnace, poor insulation, or a system in need of tuning. We perform thorough evaluations to identify inefficiencies. This may involve calibrating your current system, recommending maintenance to improve its performance, or discussing energy-efficient replacement options that are right for your home and budget, all aimed at reducing your monthly costs.
