What To Do If Your HVAC Isn’t Blowing Cold Air
There could be so many reasons that your HVAC isn’t blowing cold air. Some of these issues can be solved by you or at least checked out by you. For a central air conditioning unit there is usually an outside unit that can be found. A lot of the time this is where the problem is and this is why your AC unit is not blowing out cold air. Here are a few things you can check if your AC unit isn’t blowing out cold air.
Coils- If your AC unit is running, but it doesn’t seem to be cooling anything off then you should start by checking the outside unit. Because the unit is outdoors this gives the opportunity for debris such as leaves and twigs to find themselves inside of the unit. These debris could block off the coils and cause the AC unit to sound like it’s running but it isn’t cooling anything down.
Leaks- Another common issue is leaks from your AC unit. If your AC is leaking refrigerant then this is definitely the reason for your unit not producing cold air. The refrigerant in your AC unit is of course important to filtering and cooling the air that is blowing out of your unit.
Filter- Sometimes the filter can get clogged up and if this happens then the air passing through won’t be as potent. This will make your AC seem like it isn’t cooling but it could be because there isn’t enough air passing through so it doesn’t feel like it’s doing anything. Sometimes the filter can be cleaned by the homeowner but sometimes it needs to be cleaned by a professional.
When To Call A Professional HVAC Contractor
There are times when you should definitely call an HVAC contractor to come to assess the issues that you’re having. Sometimes it’s okay to try a little bit of checking when it comes to your AC unit not blowing out cold air. Easy things like checking for debris in your outdoor unit are easy for a homeowner to do, but what about other things? Here are some warning signs that you should look out for and call an HVAC contractor if you notice any of these things.
Strange Sounds- Strange sounds are the number one thing to watch out for when it comes to your HVAC system. Sometimes it may not be blowing out cold air but there is also a sound coming from it. This could just be debris stuck in your unit, which homeowners can look into for themselves, but sometimes the sound could mean something worse. AC units are mostly super quiet unless there is a problem, so if you hear grinding or clicking noises then you should call an HVAC contractor to check it out.
Not Cooling- Like we stated above it is okay to check some areas of your unit for issues that might cause your AC unit to no longer blow cold air. However, if you’ve checked all the areas and nothing apparent seems to be causing the issue then it is a good idea to contact an HVAC contractor to come out and take a look at your unit and determine the issue.
Rise In Monthly Bill- A rise in your monthly bill is a huge indicator that something is wrong. If you have a high bill and there is an explanation for it then that is okay, but unexplained high bills all of a sudden is a red flag. Your bill should not fluctuate that much from month to month so if there’s an increase then that is a sign that things aren’t running properly. If there is damage or a blocked filter or a similar problem then your AC unit will have to work harder to produce cold air. This will cause your bill to skyrocket. It is always safe to contact an HVAC contractor to check your unit if you have an abnormally sudden high bill.
If you notice any of these signs you should contact an HVAC contractor as soon as possible. Leaving AC unit problems to get worse can cause you more of a headache and more money to fix the extra damages. Your AC unit is important to keep your family comfortable when it comes to the hotter seasons so keeping up with it is essential.
The Bottom Line
HVAC units are important to keep up with because if there are any problems with them then it can cause you stress, cost more money and it will be uncomfortable for anyone living in your home. HVAC units must be maintained and this is something that many people don’t know. Checking on your unit and watching out for warning signs can save you a lot of time and money if you can get it fixed as soon as possible. Some things can be checked by the homeowner if your AC unit isn’t blowing cold air, but some warning signs should be automatically reported to an HVAC contractor. This is because leaving problems unattended for a long amount of time will make your bill high, it will cause you discomfort in your home and it will cost more money when it comes time to fix it because of extensive damages caused by leaving it unfixed. An HVAC contractor will help to inspect your unit and determine any problems and solutions if there are any. They are professionals who are here to help maintain and fix any HVAC problems that you might have.
