I am very particular with the referral partners I work with. Referring my clients to a house inspector who will educate, understand, and go the extra mile for my clients is so important. Brad Hanson from Hanson Inspections has proven himself to be one of the best home inspectors I have had to privilege to work with over the years. Here is Brad letting giving us a few tips on how to maintain and upgrade a few specific rooms in our homes.
The warmer days of summer are upon us again. Some days may be too warm, and that’s when you can really appreciate a good central air conditioning system. Here are some tips and suggestions to help keep yours running smoothly.
A building’s central air-conditioning system must be periodically inspected and maintained in order to function properly. While an annual inspection performed by a trained professional is recommended, homeowners can do a lot of the work themselves by following the tips offered here.
Clean the Exterior Condenser Unit and Components
The exterior condenser unit is the large box located on the side of the house that’s designed to push heat from the indoors to the outdoors. Inside of the box are coils of pipe that are surrounded by thousands of thin metal “fins” that allow the coils more surface area to exchange heat.
Follow these tips when cleaning the exterior condenser unit and its inner components – after turning off power to the unit, of course.
- Remove any leaves, spider webs and other debris from the unit’s exterior. Trim foliage back several feet from the unit to ensure proper airflow.
- Remove the cover grille to clean any debris from the unit’s interior. A garden hose can be helpful for this task.
- Straighten any bent fins with a tool called a fin comb.
- Add lubricating oil to the motor. Check your owner’s manual for specific instructions.
- Clean the evaporator coil and condenser coil at least once a year. When they collect dirt, they may not function properly.
- Inspect the Condensate Drain Line
Condensate drain lines collect condensed water and drain it away from the unit. They’re located on the side of the inside fan unit. Sometimes there are two drain lines—a primary drain line that’s built into the unit, and a secondary drain line that can drain if the first line becomes blocked.
Homeowners can inspect the drain line by using the following tips, which take very little time and require no specialized tools:
- Inspect the drain line for obstructions, such as algae and debris. If the line becomes blocked, water will back up into the drain pan and overflow, potentially causing a safety hazard or water damage to your home.
- Make sure the hoses are secured and fit properly.
- Clean the Air Filter
Air filters remove pollen, dust and other particles that would otherwise circulate indoors. Most filters are typically rectangular in shape and about 20 x 16 inches, and about 1 inch thick. They slide into the main ductwork near the inside fan unit. The filter should be periodically washed or replaced, depending on the manufacturer’s instructions. A dirty air filter will not only degrade the quality of the home’s indoor, but it will also strain the motor to work harder to move air through it, increasing energy costs and reducing energy efficiency. The filter should be replaced monthly during heavy use during the cooling seasons. You may need to change the filter more often if the air conditioner is in constant use, if any family members have respiratory problems, if you have pets with fur, or if it’s particularly dusty indoors.
Cover the Exterior Unit
When the cooling season is over, you should cover the exterior condenser unit in preparation for winter. If it isn’t being used, why expose it to the elements? This measure will prevent ice, leaves and dirt from entering the unit, which can harm components and require additional maintenance in the spring. A cover can be purchased, or you can make one yourself by taping together plastic trash bags. Be sure to turn the unit off before covering it.
