Is Your Air Conditioner Blowing Hot Air? Here’s Why (and How to Fix it)

Every homeowner has delt with tempremental Air Conditioning Units, one of the top problems we see is in systems is it will shootout warm air when it is supposed to be cold. Here at J&W, we have heard it all and we are here to answer why these issues arise in the first place.

The immediate thing that homeowners usually do is to reach out to a professional for an emergency repair. Definitely reach out to your HVAC provider however there are a few things you can do before calling!

Check the Thermostat

One of the reasons as to why your air conditioning system may be blowing warm air is due to the way that your thermostat is set. This may soundquite ridiculous, but it is easy to miss. Make sure that you have your thermostat set to “Cool” instead of “Heat.”

Check the setting of “Auto” and “On” as well. When you have it set to “On” the blower will continue to run, and what is going to come out of it is likely going to be warm air that is circulating your home. Setting the system to “Auto” will help prevent constant air circulation. The unit will kick on with cold air once the sensor notices the temperatire rising.

Vent Blockages

Another step to think about is if you have a vent blockage or a restriction in the airflow register? First, check your air filter and see if there is a build up. When you have airflow restrictions, it can cause a warm air flow.

Electrical Issues

Your outdoor unit and indoor unit need to work together  in order for your system to correctly blow out cool air. When the outdoor unit is not functioning, it could be a result of a blown fuse or a circuit breaker that has tripped. When this occurs, the unit outside is not going to run. Reach out to us in this case so that we can help you address this electrical issue in a safe and efficient manner.

Out of Refrigerant

An air conditioning system needs a chemical known as refrigerant. This allows the the air conditioner to blow out cool air. When the refrigerant is low or has run out entirely, the air will in turn be warm. The refrigerant levels can be recharged. This is not a normal situation, if your refrigerant runs low within a couple years of your AC purchase there may be a leak. In this case, call us and we will address the leak. Otherwise, you will run into the same issue again very quickly.

Knowing these few tips might save you from a technician visit!

Just had an entirely new, full HVAC install done at our old house in Riverside, which was a fairly big job. Brian and... Will did the installation, and were awesome. There was going to be issues leveling the air handler in the attic, so they moved it to a new spot and hung it instead, getting new parts/changing the plan on the fly. We're much happier with this new setup and location of the air handler. I really appreciated this, their professionalism/thoroughness, and flexibility. Brian and Will worked super-hard, and double-checked everything once the job was done. Would use this company more

Two installers here early this morning. Worked all day. Very professional, extremely well mannered and quick to answer... all my questions. They are Dustin and Robert. Both men went above just installing my new unit, they were personable and knowledgeable in what they were doing. I was surprised when I found out these two hadn't been working that long together. They worked extremely well together. I highly recommend this two more

A snake crawled into my outdoor condenser and stopped my 16 year old Trane last week on Thursday. The power surge took... out my blower unit circuit board and the motor. I called J&W and Rob was over within two hours of my call. I was spec'd a new York 17 seer system and it was up and running on Monday. Technicians Jason and Brian arrived promptly and every facet of the installation was thorough. When completed, I would not of even known they were there except they left my garage cleaner! Thanks J&W!read more
