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 I knew the house was outdated.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 The Weather Can Affect Your Home's Air Conditioner

Mary Gonzalez

Your air conditioner's compressor is installed outside, so you may assume that it is built to withstand the various weather conditions it is exposed to. However, this isn't always true. It helps to how the weather can harm an air conditioner so that you can prevent the need for a potential repair. 


If you have a torrential downpour in your area, it is possible that the water levels rise to the point where your air conditioner's compressor is now underwater. While it is a good idea to install a compressor in an elevated spot, even if it is on a raised slab of cement, the water levels may be high enough to cause water to get into the system. 

Start by shutting down your air conditioner so that it doesn't run in this type of outdoor weather. You could cause major damage to the motor if it is running while submerged. There are also many electrical components that can become damaged due to corrosion, so it is worth having the unit inspected by a professional to find out how much damage was caused. The fins of the unit will also need to be cleaned, since they may now be filled with dirt and debris.


Your air conditioner actually has a minimum temperature the outdoor conditioner needs to meet before you can turn the unit on. The magic number for many units is 60°F, though it's worth checking the user manual for the exact number. The reason for the temperature cutoff is because of how the refrigerant reacts at this temperature. You could end up ruining the compressor as a result.

The mistake of running the air conditioner when it's cold is often made when testing the air conditioner off season. This can happen when selling the home when it's too cold out, but a potential buyer wants to test that the air conditioning still works. 


Hot outdoor temperatures often lead to running the air conditioner longer than necessary. It can become problematic if the compressor is not in a shaded area, since shade helps prevent the unit from becoming too hot and being damaged as a result. A heatwave can also cause the air conditioner to be on all the time. If the air conditioner never gets a break, it puts unnecessary wear on the air conditioner. You'll end up having to repair the air conditioner prematurely, which is not the ideal thing to have happen in the middle of summer.
