Common Problems with Older HVAC Systems: What You Need to Know

As your home's air conditioning unit ages, the chances of it experiencing a short circuit or other electrical problems increase. Common electrical issues include faulty capacitors, hermetically sealed relays that have been forced to open or close, and circuit breakers that turn on frequently. Faulty wiring can also contribute to an electrical fault or, in more serious cases, a fire in the air conditioning unit. In Cleveland, TN, the average lifespan of an HVAC unit is 8 to 14 years.

This is due to exposure to natural elements such as moisture, heat, and storms. The frequency of use, maintenance of the air conditioning unit, the size and type of the air conditioning unit, and the manufacturer all influence the effective operating time of your air conditioning unit. When your air conditioner starts to age, you may experience a refrigerant leak if it is always running low on refrigerant. Adding more coolant won't solve anything; you'll need to repair the leak in the refrigerant line or consider buying a new HVAC unit if it is located in the compressor.

Refrigerant leaks not only affect the performance of the air conditioning unit but are also harmful to the environment. In addition to general wear and tear, your air conditioner could be operating less efficiently than a new HVAC unit due to damage caused by fans, compressor, or coils. This will make your air conditioner work harder and affect how it cools your home, resulting in higher energy bills. Poor airflow can also lead to health problems such as aggravated allergies, dry throat, sinuses, and sore throats. You should inspect and repair your air conditioning system at least once a year to ensure that it continues to operate in optimal condition. A certified HVAC expert can analyze any problems with your HVAC system that may be preventing proper air flow into your home and correct them.

High Cooling Costs

High cooling costs are another common problem faced by older homeowners.

As your air conditioning system starts to break down due to increased wear and tear, its efficiency decreases and you'll end up paying higher electricity bills.

Carbon Monoxide Leaks

Carbon monoxide (CO) leaks and CO poisoning are very serious issues that can occur in any system but are especially likely in older units. Furnaces can rust or develop faulty parts and cause carbon monoxide to leak. Outdoor pollutants can easily reach an older home through cracks in walls and windows.

Poor Indoor Air Quality

Outdated HVAC systems may not filter harmful particles from the air which can lead to poor indoor air quality and respiratory problems. If you have one or more of these problems and your heating, ventilation, and air conditioning system is 15 to 20 years old, it's time to replace it. The expert HVAC technicians at Easy AC can provide you with expert recommendations to help you decide if you should repair or replace your air conditioner.
