Learning About Commercial HVAC Systems

Hello, my name is Jacob. I would like to talk about proper installation and repair of the HVAC system in your commercial building. Full scale HVAC systems for commercial buildings require ongoing maintenance and repairs to keep every floor and room at a comfortable temperature. These temperature control systems also control the air quality in the building by sending the airflow through filter elements. My site will cover all aspects of the upkeep needed for these systems. I will also talk about the benefits of keeping your air quality and temperatures at desirable levels. Thanks for coming to visit my website.

Do Window AC Units Need HVAC Repair?

Isaiah Chapman

Well-maintained window air conditioning units should last you an average of 10 years. If you're hearing unusual noises coming from your AC unit or if it is leaving a foul smell in your home, consider replacing it if you plan to live there for another 5 to 10 years. Repairing it may cost you more than it's worth due to depreciation and the labor costs involved in hiring an HVAC contractor. If you decide to keep the unit, consider making minor repairs yourself.

To DIY Repair or Not?

All residential window AC units have four common components that you need to know about: the compressor, the evaporator, the temperature sensor, and the condenser. Once you know what each component does within your unit, you can troubleshoot and make a few repairs. If the parts are located deep within your AC unit, it is best to call your HVAC professional for repairs. Here's a quick overview of the parts and what may be wrong if your AC unit isn't working.

The Compressor

Compressors compact your AC unit's cooling agent—Freon. If the compressor isn't turning on, your AC unit won't blow cool air into your home. This could simply be due to dirty coils or that your filter may need to be changed. Another reason could be that the compressor may be shot and you need a new one. If neither of these options pans out, you might check to see what kind of power is getting to your unit.

The Evaporator

Sometimes your evaporator coil gets very dirty and clogged. Condensation freezes on the dirt that collects on the coil. This causes the heat transfer from the unit to cease working. Basically, the unit won't take the heat from your room and send it outdoors. Your AC unit won't work if the evaporator coil quits. Most coils are located deep within your unit, so in this case, you need to call your HVAC repair contractor instead of doing it yourself.

The Temperature Sensor

Located close to the evaporator coil is the thermostat. The thermostat senses the temperature of the air entering the air conditioning unit as it flows over it. If the air is too hot or too cold, the sensor adjusts the air to the desired temperature setting. This one is also one for your HVAC professional.

The Condenser

While the evaporator coil lies deep inside your AC unit, the condenser faces outside to move the heated air from the room to the outside of your home. This cools off your room. If your condenser stops working, the heat transfer won't happen. Your unit will fail to cool your home and you will either need to repair the unit or replace it.

You can see how the parts work together to make your home a comfortable temperature. If one component fails, it will eventually affect the other components. It can be dangerous to fix an electrical appliance like a window air conditioning unit on your own. If you're not comfortable with making any repairs yourself, find an HVAC professional to do the job.
