Patching an Old HVAC System

When I married my husband ten years ago, I reluctantly agreed to move into the older brick home he already owned. I knew the house was outdated. Unfortunately, I didn’t have any experience renovating an older place. Immediately, I noticed the old central air conditioning unit in the home. After thoroughly inspecting the equipment, I was afraid the ancient unit wouldn’t make it through my first summer in my new place. Thankfully, I was wrong. After ten years, this same air conditioning system is still running smoothly. However, it has received some diligent care from a reputable HVAC contractor over the years. On this blog, you will discover the ways an HVAC contractor can restore an older air conditioning unit.

Three Factors Indicated by Low Refrigerant Levels

One of the most common air conditioner problems is a low refrigerant level. Low refrigerant levels can result from a variety of different scenarios, including the development of a leak in the system or the improper installation of the air conditioner system.

Regardless of the exact cause of low refrigerant levels, such a malfunction in your air conditioner will always require you to address the following three issues.

Simply refilling refrigerant isn't enough

In all air conditioners, refrigerant is designed to cycle through a closed system. This means that it should never be low if the air conditioner is functioning properly. Air conditioner refrigerant is not like gas in your car. It shouldn't run out over time or need to be replaced. While refilling your refrigerant might temporarily allow your air conditioner to function as before, your refrigerant level will go down again. 

You need to find the underlying problem that is allowing refrigerant to escape if you want to permanently correct the problem. An air conditioner that's leaking refrigerant will cause you future repair needs and expenses if you don't permanently  stop the leak. 

You might want to consider replacement

If your HVAC technician notifies you of a low refrigerant level air conditioning system, you definitely need to get a quote on the cost of repairs before the repairs are performed. Correcting an air conditioner leak can be expensive, and it might turn out to be more affordable to replace your system than to have the leak corrected. 

It's especially likely that replacing your air conditioner is more economical if you have an older air conditioner that is likely to soon need replacement anyway. Remember that an air conditioner typically lasts between 10 and 15 years. If your air conditioner is around 10 years old, it's a good idea to simply replace the system if it develops a costly leak. 

You're paying too much for your utility bills

When your air conditioner develops a leak, you'll probably notice that your utility bills go up during the hot season. An air conditioner is designed to function optimally with a certain amount of refrigerant in it. When your refrigerant level is low, it won't cool your home as easily. In fact, you might even find that your air conditioner is incapable of cooling your home until the missing refrigerant is replaced. 

If you've been wondering why your utility bills have gone up lately, it could be because your system is leaking refrigerant. Have a professional like Bill's Heating & Air Conditioning examine your unit.
