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 I knew the house was outdated.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.

How to Keep an Air Conditioner from Overheating

Mary Gonzalez

Air conditioners work to keep your home cool in the summer months but can suffer from overheating themselves if they are not properly maintained. There are three main reasons why an air conditioner's temperature will reach unacceptable levels, causing it to cease to function. Thankfully, understanding what these reasons are and what you can do to prevent each of them from occurring can help prevent your air conditioner from malfunctioning during the hot weather.

Clogged Filters

Your air-conditioning system makes use of an air filter to keep dust and other contaminants from entering your ductwork and being blown around your house. If the air filter becomes clogged, your air conditioner will not be able to work efficiently and will quickly begin to overheat while it is operating. In order to prevent this from happening, you should clean out your air filter at least once a month during the summer to ensure proper air flow. Check your owner's manual to determine where the air-filter housing within your air-conditioning system is, and what type of air filter you have.

If you have a replaceable air filter, simply take the filter with you to a hardware store and find a replacement of the same size. Just throw out the old filter, and slide the new filter into the housing within your air conditioning unit.

For a reusable filter, simply wash the filter off with soap and water and let it air dry, replacing it within the housing when it's no longer wet.

Dirty Condensers

The exterior unit of your air conditioning system is known as a condenser, which removes the heat from the interior portion of your air conditioner. If your condenser becomes dirty, it cannot transfer heat out of your home as easily, causing the temperature of your air conditioning system to rise.

To prevent this from happening, you can simply remove the side panel from your condenser and use a clean, soft rag with a small amount of water to clean off the dirt from the interior of the unit. Alternatively, you can contact a contractor for a deeper, more holistic cleaning if your condenser is seriously dirty.

Refrigerant Leaks

Refrigerant is the chemical within your air-conditioning system that works to cool the air down within your home. A leak will mean that your air conditioner will not be able to work as effectively and will begin to overheat while in operation.

A refrigerant leak can be very hard to notice but usually manifests itself as a failure of your air-conditioner system to cool down your home. If a refrigerant leak does occur, you should contact a professional immediately, as long-term exposure to this can be dangerous to your health. The leak will have to be repaired and the refrigerant receptacle refilled will have to be refilled, and you cannot do that yourself, so you should call your air-conditioning service.
