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 I knew the house was outdated.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.

Preparing Your Furnace For Cool Weather

Mary Gonzalez

If you use a furnace to heat your home, doing a few routine maintenance steps before you turn it for the season will help minimize the risk of unnecessary downtime when it is needed most. Many people will enlist the help from a heating contracting service to take a look at their furnace if it is not running properly. If you have not experienced any problems, however, you may be able to undertake some maintenance steps on your own. Here are some instructions to follow when preparing your furnace for the next cold snap.

Change The Filters

Place a new air filter in your furnace before you begin using it. This is an easy swap as the old one will simply slide out of place, allowing you to put in a new one. Consider purchasing a heavy-duty filter to help eliminate pet dander and other allergens from the forced air your furnace emits. Leaving a clogged filter in place will alter the efficiency of your heating, making your furnace work harder, and making you use more energy as a result. If you use an oil furnace, swap the oil filter with a new one as well.

Check The Flue

The flue pipe that runs from your furnace to the vents around your home should not have any cracks or holes within the structure, letting heated air out around your furnace instead of through the rest of your home. Do an examination of this pipe and cover any questionable areas with foil tape. If the cracked area cannot be covered completely with foil, you will want a repair service to place an entirely new pipe in before you need to use your furnace to cool your home.

Clean The Chamber

Clean out your furnace's combustion chamber to remove any old soot or debris from the previous season. Make sure there is no power running to your furnace before you do this clean out, as you will be working right where the energy source is heated. Look for a red switch plate near your furnace and switch it to the off position. If you cannot locate this power switch, turn off your furnace at your main circuit breaker box.

The combustion chamber is located in the front of your furnace, usually behind a hinged door. Scrape the sides and ceiling of the chamber using a wire brush. Use a shop vacuum to remove any charred material from the bottom of the combustion chamber. Contact a company like Drew Green Heating & Cooling for more information.
