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 I knew the house was outdated.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.

Troubleshooting Your Ventilation

Mary Gonzalez

If you are a homeowner, then you know that few things are more frustrating than problems with your ventilation. Blockages in your vents can lead to terrible smells and prevent your heater and AC from working, Therefore, it is important that you understand how to deal with basic ventilation problems.

Diagnosing the Extent of the Problem

The first thing you need to do if you suspect a problem with your ventilation is to determine the scope of the problem. In order to do this, you will want to isolate every room that has a vent in it. Close as many doors and windows as possible so that you can get the most accurate reading.

Then, you'll want to turn on the fan. Check each vent to see if you can feel air movement. If you can't feel any air, then you should turn on the heater or air conditioner. Let it run for an hour or so and then check each room again.

If you could not feel the fan running in a room, but the temperature did change, then there might be a partial blockage that is reducing the efficiency of your ventilation. In such a case, affected rooms will heat up or cool down at a slower rate than the other rooms.

If you could not feel the fan running and the temperature did not change after an hour, then you might have a full blockage. A full blockage can be pretty difficult to deal with, so you might actually want to call a pro.

If you can't feel a temperature change in any of your rooms, then the problem might actually lie with your heater or AC. In order to test this, try the heater if you tried the AC earlier or vice versa. You don't want to poke around in your vents or hire professional cleaners if it turns out that the problem was with your heater or AC instead.

Fixing the Problem

Once you have determined which rooms are affected, you can try to rectify the situation yourself. In order to do this, you will want to remove the vent cover in the affected room and look around with a flashlight. If you got lucky, then you might be able to see the blockage from the vent covering. Removing it with a long, thin object might be possible.

However, it is also very likely that the problem is deep inside your ventilation system. If that's the case, then you'll want to call the pros. Ventilation companies like Mike's Bremen Service Inc have specialized vacuums with extremely long hoses that can reach deep into your vents.
