It’s pretty frustrating when something big and expensive doesn’t work, right? Like your central air conditioner? We all get that feeling. It’s disheartening, especially if it happens in the middle of the summer. In New Port Richey, AC repair is a bustling business – we’ve seen a lot of problems in our time.
If you’ve got an air conditioner that seems to blow warm air all or some of the time, that’s a real issue. We’re here to help you figure out what might be causing it, and determine what your best course of action would be to get it fixed.
You may not be able to repair many of the things we’ll talk about here, but sometimes, just diagnosing a potential problem is a big help to those that can. And, of course, there are a few problems in here that you can take care of on your own. Let’s dive right in and see what might be causing the temperatures in your home to climb.
Check your thermostat and make sure it’s set correctly.
We know that’s the HVAC equivalent of the IT helpdesk saying, “Is the computer plugged into the wall?” But trust us, and go check. Not only should the device be set to COOL, the temperature should be set a few degrees lower than room temperature. Otherwise, your system isn’t going to turn on at all.
And if you’ve got it set to FAN or ON mode, you might mistakenly assume that it’s blowing around air that hasn’t been properly cooled before recirculation. That’s because, unlike COOL or AUTO, in ON and FAN modes (which may vary by manufacturer, or course) your blower never stops pushing air around.
It is also possible that your thermostat itself is malfunctioning or experiencing problems of some kind. It may need to be replaced if that is the case.
You should check your filters for airflow problems.
First, does it seem like the air isn’t coming out with the same force you’re used to? Or is the air slightly musty or stale? Both of those could be signs that your air filters and intake vents are due for a good cleaning.
When those aren’t clean, they slow down the air moving over your coils inside your system. This in turn causes a precipitous temperature drop, which freezes the condensation, causing ice to form inside your system. When that happens, your coils can’t cool the air any longer, and what comes out of your vents is … you guessed it … warm.
You should clean or replace your filters once a month, or as directed by the manufacturer. A good way to remember is to keep the filters somewhere visible – on a garage shelf or in the laundry room, for instance. This way, you see them periodically and are reminded to perform this simple but vital task. If your system has frozen over, it will need to be thoroughly de-iced before you can use it again.
Check for dirty coils.
The symptoms for dirty coils look an awful lot like the symptoms for filter issues. That’s because, if you’ve gone without annual preventive maintenance, or something has caused an abnormal buildup of dust and debris in your ducts, your coils can end up dirty.
And dirty coils also freeze over, for largely the same reasons. It’s not too difficult to check for this. The condenser coil is located in your outside unit. Go take a look; if you’ve got weeds, grass, or vines growing on or near your unit, trim them away. Then sweep all debris away from your unit.
It is very important to keep at least a couple of feet around the air conditioning condenser unit clear of anything that could get into the chassis and cause problems.
Check for electrical issues.
A lot of voltage is required to run your central air. It involves a significant array of wiring, capacitors, motors, compressors, and coils. If at any point, one or more of those isn’t receiving the correct electrical signal, it could trip a breaker.
Overheating can also trip a breaker, as most modern units are equipped with safety features to prevent overheating and flooding. So if your air is blowing, but it’s not cold, you should go and check the condenser, which is your outside unit. If that’s not on, your indoor unit is just going to be blowing room temperature air around.
You can troubleshoot a few simple things with your electrical system, but if the AC system shuts off the breaker more than once, or you find a blown fuse, shut the breakers off and call New Port Richey AC repair. We absolutely do not recommend attempting to diagnose or repair electrical issues.
The cost of professional service is well worth it, for your safety
If you’re low on refrigerant, your unit will blow warm air.
That’s because refrigerant is not able to cool the air before it recirculates. Because refrigerant is contained within a sealed system, low refrigerant is a sure sign of a leak somewhere in your air conditioning system.
All refrigerant requires a licensed handler, so you’ll need to call local air conditioning contractors in to find the leak, repair it, and charge your system. If you have an older system that uses R-22 refrigerant (Freon), you will discover that it has been discontinued and is being phased out.
The contractor may have to recommend a replacement system at that point, unless your system is new enough to be converted to a modern refrigerant, if that’s even possible.
