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 I knew the house was outdated.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.

3 Causes For Concern With Residential Heating Units

Mary Gonzalez

Residential heating repairs can be distressing. You depend on the appliance to provide hot air to heat up the temperature of your house. Once this has been compromised in some way, the indoor temperatures will stop to drop and can become very cold depending on the weather outside. It is good to have a backup source of heat like a space heater, but a lot of people aren't that lucky. If you are stuck in a situation where your furnace isn't working, you can try troubleshooting it. This is a list of some common furnace problems and what causes them.

Inadequate Heat

One main concern with a furnace is when it isn't producing an adequate amount of heat. The number one reason that this happens is a dirty or damaged air filter. A filter will build up with dust as the furnace runs. As you can imagine, it will become quite dirty after a while and air will not flow through it as easily. You should check the filter at least once a month to see how full it is. Wipe it off with a damp rag on each side and replace it in the heating unit once it is clean. Damaged filters should be replaced. Simply write down the serial number on the filter and take it to any home improvement store. They will be able to match you with a filter that is compatible with your furnace.

Furnace Doesn't Blow

A furnace that doesn't blow any air is worse than one that blows inadequate air. The issue lies with the blower on the unit. Every appliance should have an inspection window on it. Locate the blower using your user's manual that came with the furnace. If there is any debris by the blower, this may be the problem. There should also be a blinking light by it. A green light means everything is fine, but a red light means there is a serious problem and it should be repaired right away. You will need a professional HVAC contractor to solve this issue for you.

Noisy Units

Heating units will make a noise every time they are on. After a while, you will recognize what is normal and is not. Abnormal noises coming from the ductwork or the furnace indicates a problem within the system. A technician should be sent to locate the problem before the furnace is damaged even more.

Conclusion

An HVAC contractor is always your best bet when it comes to solving heating or cooling problems in your home. You should keep one on speed dial during the cold months in case something goes wrong and you need emergency furnace services.
