Top 3 Heat Pump Issues in Hot Weather (And How to Fix Them Fast)

Heat pumps are an efficient way to cool your home during hot weather, but like any HVAC system, they can run into trouble when temperatures rise. Understanding the most common issues and how to address them quickly can help you stay comfortable all summer long. Here are the top three heat pump problems you may encounter in hot weather — and how to fix them fast.

1. Reduced Cooling Efficiency
When your heat pump struggles to cool your home, it could be due to a dirty air filter, clogged coils, or low refrigerant levels. Dirty filters restrict airflow, while dirty coils reduce the unit’s ability to transfer heat. Low refrigerant often points to a leak.
Quick Fix:
Check and replace air filters monthly during peak use. Clean your outdoor unit and coils to improve efficiency. If you suspect a refrigerant leak, it’s time to call the pros at Maple Air. We’ll inspect the system, repair leaks, and recharge refrigerant safely.

2. Heat Pump Not Turning On
If your heat pump won’t start, it may be due to a tripped breaker, faulty thermostat, or damaged capacitor. Electrical issues can worsen during high-demand summer months.
Quick Fix:
First, check your circuit breaker and reset if needed. Confirm that the thermostat is set to “cool” and the temperature is below room temp. If it still won’t turn on, it could be an electrical or component issue — contact Maple Air for immediate assistance and diagnostics.

3. Short Cycling
Short cycling occurs when the heat pump turns on and off too frequently. This can be caused by an oversized unit, thermostat problems, or restricted airflow. It leads to higher energy bills and unnecessary wear and tear.
Quick Fix:
Ensure vents are open and unobstructed, and filters are clean. Check if your thermostat is functioning properly. If short cycling persists, Maple Air’s team can assess your system and recommend adjustments or replacements to ensure optimal operation.
