When you live in Jupiter, Florida, you can attest to the need for a working air conditioner throughout the year, and especially during the summer months. With average temperatures between the mid-60s and mid-80s all year long, you probably keep your cooling system on at some point during all 12 months.

If you lower the temperature on your thermostat but only feel warm air coming through the vents, this can indicate a number of problems. Some of the issues are minor, while others may require more extensive repairs, but you should always pay attention when warm air is blowing from your air conditioner.

Loss of Power

One of the causes of warm air coming through the cooling system is a loss of power. If your outdoor unit doesn’t have an electrical connection, the indoor fan may continue to blow, but the compressor can’t cool the air. Try resetting your circuit breaker to see if that fixes the problem. If it continues to trip, you’ll probably need to bring in an electrician to figure out what’s causing it to continually lose power.

An HVAC technician can also look at the electrical connections to the unit to make sure that they’re in good condition and not putting you at risk of a fire.

Clog in the Outdoor Unit

Your air conditioner has an outdoor unit that houses the compressor, which cools the air that flows through the home, along with the condenser. Since this unit sits outside, it can become clogged with leaves, grass, dirt, and other debris. You might also notice that trees and shrubs around the unit are growing into it, resulting in poor efficiency.

Keep the plants around the outdoor unit trimmed and use a broom to sweep out any debris in the housing around the air conditioner. The condenser needs an unrestricted flow of air to keep cool air moving, so warm air coming out of your vents could indicate a clog. An HVAC technician can also examine the outdoor unit for signs of blockage.

Dirty Coils

The coils within your cooling system also need unrestricted airflow to work properly. A lack of cool air can result from dirty coils that don’t have the airflow they need. They can accumulate dust and dirt over time, so regular cleaning is a necessary task of proper air conditioning maintenance. During an air conditioning tuneup, your technician will usually clean the coils as part of the service. You should never try to clean the coils yourself since they’re housed within the unit. It’s dangerous to start poking around within your air conditioner, so leave this task to a skilled professional.

Low Coolant Level

When your air conditioning system runs, it uses coolant to remove heat from the air and push cool air through the ducts and out through the vents. If your system is running low on coolant, such as refrigerant, the heat will stay in the air and come back through. Coolant shouldn’t have to be replaced, so if the level in your system is low, you probably have a leak. A skilled HVAC technician can inspect the units and determine the source of the leak and how to repair it.

Set on Heat

One of the most common reasons that your HVAC system might be blowing hot air is that it’s actually still set to heat your home. You’d be surprised to know just how many homeowners call for HVAC service only to find that they haven’t switched the system over to the cooling function. It’s an easy fix, so check that first before you try anything else. If it’s set to cool, contact an HVAC professional to take a look at the system to see what’s causing the problem.

HVAC technicians can always help with problems relating to your heating and cooling system. It’s best to leave issues in their experienced hands to prevent further damage to the unit.
