Avoid Your HVAC Not Blowing Cold Air

HVAC Not Blowing Cold Air?

(Last Updated On: June 7, 2018)

The unofficial start to summer means the unofficial worries about home cooling problems. As the weather warms up, many homeowners rely on their HVAC (particularly air conditioning) systems. As you turn on the A/C, are you having issues with the HVAC not blowing cold air?

If so, there are some simple strategies and checks every homeowner should (and can) make to review potential HVAC issues.

Why is my HVAC not blowing cold air?

First and foremost, there a handful of basic reasons that create A/C problems. For example, the following components and issues arise from time to time. Fortunately, without much knowledge, many of these potential problems require limited skills to address.

  • Power Issues, which seem like a no-brainer, actually remain the cause of many issues. Check the plug and ensure the power cord is still intact. If everything checks out, then look at the electrical panel for a blown fuse.
  • Thermostat Issues, which offers a straightforward explanation. Check the settings and temperature. Turn the temp to the lowest level to see if the A/C triggers.
  • Clogged Filters, which may restrict adequate airflow or simply shut down the A/C (on newer machines) in order to prevent motor damage or overheating.
  • Clogged Drains, which can shut down A/C units as a safety feature. A/Cs remove moisture from the air and drain outside of the home. Therefore, if a clog exists, then the system stops working.
  • Dirty Compressor, which may accumulate dirt and debris, should be checked and cleaned.
  • Ice Buildup, which derives from dirty coils or filters (or even low refrigerant). To fix, then clean the filter, coils or add more refrigerant.
  • Condensate Airflow Switch, which offers a safety mechanism that trips and shuts off the A/C unit when the drain pipe clogs. Check the switch and see if it tripped. If so, then clean the drain pipe and reset the switch.

What are the HVAC and air conditioning system warning signs?

Fortunately, home HVAC systems provide some clues and warning signs foreshadowing potential issues. Additionally, routine inspections, which simply take a few minutes every month or so, help provide peace of mind. For example, walk through your home and ask yourself a few questions about your A/C unit.

  1. How loud is the A/C?

A noisy A/C indicates that something is not right. If this is the case, there could be an issue with the compressor motor or condenser fan, which can compromise the system’s efficiency.

  1. When was the last time you replaced the air filter?

Most homeowners don’t worry about their air filter until there is already a problem present. For dirty filters, then your A/C unit might run continually, but your home temperature may not cool down.

  1. How hot is it outside?

On those unbearably hot days, the outdoor temperature could be too intense for older systems to function at maximum efficiency. If this is case, it could be time to upgrade.

  1. Did you check the thermostat?

Sometimes the problem is simple, your thermostat might just need a fresh set of batteries. Look for the battery symbol or light on your thermostat indicating the batteries need to be changed.

  1. How is the outdoor A/C unit?

If you have an outdoor unit(s), you should be able to see and hear if the fan is still on. If it is working, that is likely not a problem. However, many homeowners never think their outdoor air condenser needs any maintenance, which is not accurate.

  1. Have you looked at the drain line?

Is water surrounding the indoor unit that couldn’t have come from another source? If so, your drain line is likely plugged and you need to have a professional AC technician out to inspect the system.

The old adage “an ounce of prevention is worth a pound of cure” remain true when it comes to your air condition system as well. By having a professional technician perform annual inspections and staying on top of any maintenance issues, you can avoid potential issues, like the HVAC not blowing cold air.

How do A/C professionals make a difference?

A licensed HVAC technician ensures your system remains running in tip-top condition. Plus, they inspect the system so it remains compliant with any local and national building codes. When in doubt, enlist the help of a qualified professional rather than risk damaging your system further by attempting DIY repair.

Plus, developing a relationship with an A/C contractor helps ensure proper coverage if an emergency occurs. For example, industry experts share why patience pays off when finding a local A/C company.

“Even if you have an emergency, for example, your air conditioning has gone out and it’s 94 degrees outside, the time that you spend gathering details beforehand can save you money and a lot of headaches.”

As a result, working with a trustworthy company provides peace of mind. If your HVAC no longer blows cold air one day, then you’ll know who to call (and ideally offers 24/7 service) for such emergencies.

For example, SolvIt offers reliable service and great A/C contractors. If you have any air conditioning issues beyond your technical capabilities, then give us a call. We offer the same high quality service, anytime, any day.
