Reasons Your AC System Is Not Blowing Cold Air

Your HVAC system is likely the biggest home appliance investment you will make, and for good reason. The HVAC unit is complex and life-changing, turning your house into a comfortable home. There are many different components, and each plays an important role. So, there are several possible reasons why your AC system is not blowing cold air. In this short article, we will go over some of these possibilities. If maintenance does not cut it and you need AC repair or even an air conditioning unit replacement, then call Rooter Hero to consult with a representative and schedule an appointment. We also offer urgent dispatches for emergency cases.

Dirty Air Filters Can Block Air Flow

Air filters slightly restrict air flow by design, with the purpose of filtering out dust and debris. However, the air filter blocks more and more air flow over time as it collects dust, dirt, and other debris. If you do not change the air filter regularly, then you can expect more problems than just blocked air flow.

Dirty and blocked air filters can cause your unit to cool your home unevenly with some rooms getting too cold and others not receiving cold air at all. That dirt and debris in the air filters might also get pushed out, contaminating your breathing air and triggering allergies. Dirty air filters can also overwork your air conditioner, increasing energy bills and decreasing the unit’s life expectancy.

We recommend that homeowners replace their air filters at least once per season, or once every three months. The type and quality of the air filter is important too.

Bent Cooling Fins and Dirty Coils

Your air conditioning unit pulls in air from outside and cools it. The outdoor component of your air conditioner is called the condenser and it is largely responsible for this role. If the condenser is dirty, however, it will have a hard time doing its job. This is like the clogged air filter issue, but you will probably not have to replace the condenser. Rather, you will have to clean it, being careful not to bend or break any parts. Using soap and water to gently wipe away the dirt is one option. You can also use a hose with gentle pressure. You should also keep the area around the condenser clear of debris. Trim or remove hedges, bushes, plants, and shrubs in the area.

Damaged Components

Air conditioners call for a lot of maintenance. Staying on top of this maintenance can reduce the risk of a premature system failure, but it is not going to prevent faults altogether. Components within the unit are susceptible to corrosion, rusting, and general wear and tear. For these, you will need AC repair. If the repairs are becoming too frequent, then it might be time for an air conditioning unit replacement. Call Rooter Hero if you are worried about a unit that is breaking down too often. Our technicians can perform a thorough inspection and give you a professional recommendation on how to move forward.
