My Air Conditioning Doesn’t Blow Cold Air!


With summer well on its way, the days are starting to heat up. Homeowners across the country are beginning to rely heavily on their air conditioning units to keep them cool and comfortable. What, then, do you do if your A/C is just making the problem worse by circulating warm air throughout your home? If you’re experiencing these problems, it’s definitely time to call in an expert from Kay Heating and Air to solve your cooling woes once and for all.

Refrigerant Problems

A refrigerant is a type of super-cooling liquid your HVAC unit uses to cool the air circulating through the system. As one of the top reasons an air conditioning unit blows hot air, refrigerant leaks are usually a straightforward fix. Catching the leak in the act can be tricky because the valve is situated outside your home. Unless you’re actively watching it, you’d never realize the leak was there. Leaks typically occur with regular wear-and-tear or when a joint comes loose from heavy operation or poor manufacturing. Switching on the A/C after months of winter hibernation without servicing can cause damage to the unit, potentially leading to leaks in the outer valve. Remember: just because it’s a common problem, doesn’t mean it isn’t dangerous. Always call a professional if you suspect you may have a refrigerant leak. To prevent leaks in the future, have your unit serviced at least twice per year.

Broken Thermostats

Occasionally, the fault lies with your thermostat, not your actual HVAC unit. If you notice your unit isn’t carrying out your thermostat settings, there may be a communication issue between the two. Thermostats are usually attached to a sensing bulb and the compressor of your A/C unit. The thermostat uses the bulb to gauge the ambient temperature and adjust the unit’s operation accordingly, based on the thermostat’s settings. If your unit is capable of cooling air but simply isn’t, the compressor or the sensing bulb may be malfunctioning, leading the system to continue circulating warm air. A professional will inspect the sensing bulb for bends, breaks or kinks and service it to ensure it is properly functioning.

Dirty Air Filters

Surprising as it may be, sometimes it may only feel like the unit is blowing warm air. In actuality, the system may be functioning perfectly fine, but could be suffering from an obstruction in the air flow, preventing the home from cooling properly. Perhaps one of the simplest A/C fixes, replacing a dirty air filter can do wonders for your unit’s cooling abilities. Your air filter catches allergens, dust and debris that is circulating through the home. However, during months where pollen count or pet shedding are at their peaks, the filter can become filthy quite quickly. Without regular replacements or cleanings, the filter can block the flow of air, preventing your home from cooling.
