Five Reasons Your Heat Pump Isn’t Blowing Hot Air in Franktown, CO

Consistent heating is crucial in Colorado’s frigid winters. If your heat pump has stopped blowing hot air, a professional should inspect it. Consult Southwest Heating & Cooling for reliable heating repair in Franktown, CO.

Homeowners should understand the most common heat pump issues to best prevent them. These include:

1. A Dirty Air Filter Is Cramping Your Style (and Airflow) 

When your heat pump is not blowing hot air, the first thing to check is your air filter. A clogged filter restricts airflow to your unit, resulting in heat loss from the outside unit before the air reaches your home.

These filters are designed to catch dust, debris, pollen, and other allergens from outside. Regularly cleaning and changing them is the best way to prevent heat pump issues and improve indoor air quality.

Heat pumps require adequate airflow to function and be energy efficient. Over time, ignoring clogged filters wears your unit down and will increase your energy and repair bills. 

2. A Leak Is Causing Low Refrigerant Charge  

Refrigerant absorbs and releases heat within your unit. Low refrigerant levels often lead to malfunctions and even breakdowns. The most common cause of plummeting refrigerant levels is a leak in the system.

An inspection will reveal the leak’s location and allow your heating expert to patch the system carefully. 

3. The Reversing Valve Is Damaged and Can’t Switch to Heating 

The reversing valve redirects the flow of refrigerant to switch your unit from heating to cooling. These valves can crack, break, or loosen over time and start malfunctioning. If the reversing valve cannot switch from cooling to heating, you will notice that your heat pump isn’t blowing hot air.

These valves often need to be replaced if significant wear and tear compromises their function. 

4. You Have Incorrect Thermostat Settings or Accidental Defrost Mode 

When you notice your heat pump isn’t blowing hot air, the solution may be as simple as adjusting your thermostat. Sometimes, thermostats need to be recalibrated at the change of seasons or when power outages impact the system.

Homeowners should check that their thermostat is set correctly and wait a few cycles to determine if the issue is resolved. 

If the air is still not warmed correctly, verify that your heat pump is not in defrost mode. This setting forces your unit to blow cold air so that the outdoor coils have a chance to heat up and melt any frost. Defrost cycle issues can cause the unit to get stuck in defrosting mode and be unable to produce warm air.  

If neither of these solutions works, it’s time to contact a professional for assistance.

5. Heat Exchange Is Obstructed by Dirty Coils 

Just as the air filter can become dirty and clogged, the outdoor coils can collect debris and malfunction. There are two key coils to be aware of: evaporator and condenser.  

An evaporator coil absorbs heat and evaporates refrigerant inside it to cool the surrounding air. A condenser coil transfers heat from the compressed refrigerant to the air around it. Either of these coils may become dirty or clogged and prevent your heat pump from blowing hot air.   

Cleaning these coils thoroughly and safely requires a professional touch.
