Every summer in Lynnwood, I get the same urgent call: “Why is my AC blowing warm air?” It’s one of the most frustrating situations for homeowners. The house feels stuffy, sleep becomes uncomfortable, and everyone gets restless. I’ve helped countless families in Edmonds and Bothell through this exact problem, and the truth is, most cases are fixable. This issue isn’t just about comfort. It often signals something deeper in your system that needs attention before it becomes a costly breakdown. Let’s explore the common reasons behind warm air and how my team at Kings Heating helps restore cool comfort quickly. Common Causes of Warm Air Coming from Your AC I’ve seen hundreds of air conditioning systems over the years, and these are the most frequent culprits when warm air replaces the chill: Thermostat Settings Before assuming the worst, check your thermostat. Make sure it’s set to cool and the fan is on auto. Many service calls begin with a simple setting correction. Dirty Air Filters A clogged air filter restricts airflow and forces your AC to work overtime. Replace filters every 1 to 3 months, especially if you live in a household with pets or allergies. Refrigerant Leaks Low refrigerant is one of the top reasons ACs blow warm air. You might notice hissing sounds or ice buildup. Only certified HVAC professionals should handle refrigerant leaks to ensure safety and efficiency. Electrical or Capacitor Problems If your compressor isn’t turning on, the issue could be electrical. I’ve seen corroded wires or failing capacitors cause sudden warm air in otherwise healthy systems. Frozen Evaporator Coils Ice on your coils means something’s blocking airflow or your refrigerant levels are too low. Let the system thaw and call for service before damage spreads. Even minor problems can escalate if ignored. The key is catching them early with routine inspections or professional help.

At Kings Heating, Air & Electric, we’ve built our reputation on helping families stay comfortable year-round through energy-efficient solutions that save money without compromising performance. What to Expect During a Professional Heat Pump Installation I’ve seen many homeowners underestimate what goes into a proper heat pump installation. It’s not just about placing a unit and flipping a switch. A professional installation starts with a detailed home assessment. We evaluate: Insulation levels Ductwork condition Overall energy use and system load This ensures we recommend the right system for your home’s needs. Many service calls come from people frustrated by uneven temperatures or high energy bills, often due to poor installation. When we install energy-efficient heat pumps in Lynnwood , we look at how the system performs across Washington’s cool, damp winters and mild summers. Choosing the right size unit is crucial: Too large, and it cycles on and off inefficiently. Too small, and it struggles to maintain comfort. Once the system is selected, our technicians handle every step, including: Electrical connections Refrigerant line setup System calibration and testing Even small errors can affect energy efficiency by up to 20 percent. That’s why we take time to perfect airflow and thermostat control. After installation, we walk homeowners through filter care, smart thermostat use, and seasonal adjustments. If you’re comparing heat pump installation in Edmonds, WA , always ask about load calculations, efficiency ratings, and warranty coverage. These are the details that ensure lasting comfort and savings. Routine Maintenance to Maximize Efficiency and Lifespan A heat pump isn’t a “set it and forget it” system. Like a car, it needs regular tune-ups to perform at its best. At Kings Heating, we recommend servicing your system twice a year before summer and before winter. Too often, homeowners wait until the system breaks down, usually on the coldest day of the year. By then, a small issue such as: Dirty coils Low refrigerant Clogged filters have already caused major strain on the system. Routine maintenance helps prevent costly breakdowns. Our service includes: Cleaning coils and filters Inspecting electrical components Checking refrigerant levels Testing defrost cycles and airflow I’ve seen homeowners call for emergency heat pump repair near me because of issues that could have been avoided with a quick seasonal tune-up.
