Periodic Inspections & Maintenance of Central Air-Conditioning Systems

Central Air-Conditioning System Inspection

by Nick Gromicko

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 in this guide.

Clean the Exterior Condenser Unit and Components

The exterior condenser unit is the large box located on the side of the building that is designed to push heat from the inside of the building 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!

• Remove any leaves, spider webs and other debris from the unit's exterior. Trim foliage back several feet from the unit to ensure proper air flow.
• 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 are 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 inches by 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 indoor air quality, 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 building occupants have respiratory problems,if  you have pets with fur, or if dusty conditions are present. 

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.

Close the Air-Distribution Registers

Air-distribution registers are duct openings in ceilings, walls and floors where cold air enters the room. They should be closed after the cooling season ends in order to keep warm air from back-flowing out of the room during the warming season. Pests and dust will also be unable to enter the ducts during the winter if the registers are closed. These vents typically can be opened or closed with an adjacent lever or wheel.  Remember to open the registers in the spring before the cooling season starts.  Also, make sure they are not blocked by drapes, carpeting or furniture.

In addition, homeowners should practice the following strategies in order to keep their central air conditioning systems running properly:

• Have the air-conditioning system inspected by a professional each year before the start of the cooling season.
• Reduce stress on the air conditioning system by enhancing your home’s energy efficiency. Switch from incandescent lights to compact fluorescents, for instance, which produce less heat.

In summary, any homeowner can perform periodic inspections and maintenance to their home's central air-conditioning system.

Safety Recall - Genie Garage Door Openers

Most of the homes I inspect have garages with garage door openers. Today, the United States Consumer Product Safety Commission (CPS) announced a recall of approximately 10,000 Genie Garage Door Openers sold the U.S. While no injuries have been reported, there have been reports of the control board overheating in some units. If you have a Genie brand garage door opener, visit the CPS website at http://www.cpsc.gov/en/Recalls/2014/Genie-Recalls-Garage-Door-Openers/.

Tips for Foreclosure Purchases

Buying a Foreclosure

by Nick Gromicko 

 

 

Purchasing foreclosed homes in desirable areas at below-market values can be a sound investment strategy. Appreciation on their original prices may be tax-free.  Buying foreclosed rental properties can provide positive cash flow, as well as valuable tax deductions. On the other hand, buying a foreclosure involves homework, patience, and a certain amount of luck. For those wishing to get a bargain house through the foreclosure process, it’s best to learn the basics.

 

Four Ways to Buy a Foreclosed Home

• A presale is when the prospective buyer negotiates with the current owner before the house is foreclosed upon. Presale discounts can be considerable, but communicating and reasoning with the owner isn’t always easy; they might have legal problems, lost their phone service or electricity, or greet you with suspicion, having already been hounded and threatened by creditors. And after time and energy have been invested, the deal can fall through if the owner comes up with the money to repay their debt, or for any number of unexpected reasons. With persistence, however, the seasoned real estate investor can profit from presales. To find out about presales, you can try one of the following avenues:
  • Ask your local county court how to search new notices of default.
  • Find out if the County Recorder has data available online.
  • Look in the "legal notices" section of the newspaper for properties that are coming up for sale at public auction. Take note of the address, the property owner’s name, the tax ID, and whatever other information is contained in the ad.
• A foreclosed home may be sold at a public auction, in which buyers can expect a discount of 10% to 25% of market value. Interested bidders are generally required to show proof of financing, and must have a minimum cash deposit before they are qualified to bid. It might be impossible to gain entry to inspect the interior, too, which makes this type of purchase risky. The local building department may have permit records that can clue you in to the building’s layout and appearance.
• A real estate-owned (REO) sale is a transaction where a foreclosed house is purchased directly from the bank. These properties typically wound up in the bank’s portfolio after failing to sell at auction. REO investments are relatively safe, as there are no tenants to evict or hidden liens and, unlike properties sold at public auction, buyers can usually receive a mortgage to pay for them. And purchasers might even get an unused house; the slow economy has left many builders at the end of their construction-loan periods without finding buyers for the homes, in which case the bank will foreclose on the brand new homes. Unfortunately, REOs are usually offered at near-market prices to recoup the costs of property taxes, maintenance and legal fees. To find REOs, try the following:
  • Check lenders’ websites, as they may have a list of their REOs, along with contact information for the appropriate real estate agent.
  • Call lenders and ask to speak to someone who handles their foreclosures.
  • Check newspapers.
• The Department of Housing and Urban Development has tens of thousands of HUD homes whose previous owners defaulted on federally issued loans. After a period during which local governments gain exclusive buying privileges, they become available to individual buyers who pledge to live in the property. After another 10 days, investors may bid on the property. It’s difficult to make a profit on these houses, as HUD releases them at near-market values.

Tips for Foreclosure Purchases

• Invest time in research and preparation. Those new to the field should spend some time learning the variables of foreclosure investing before making any purchases.
• Budget carefully to prepare for the unexpected. The house may require unforeseen repairs, such as a leaky roof or unstable deck. The price tag of the home itself is often just the first of a series of fees. What if you planned on rental cash flow to cover the mortgage, but you can’t find a tenant?
• Avoid buying a foreclosure sight-unseen. Try to see the house yourself before buying it, or hire someone to evaluate at it in your absence. Distant investors are buying up properties unseen in bulk, and they’re often unpleasantly surprised at how much they’ve been misled.
• Evaluate the neighborhood. If the foreclosure is rife with problems, but it’s in a desirable area with high property resale values, it may still be worth it to make a low offer. An area with several foreclosures or a high crime rate can undermine an otherwise good deal, however.
• Consider how long the house has been vacant. Building damage – and the costs required to make the house livable - generally increases with the time that has lapsed since the last tenant vacated. Pests are a particular issue in houses that have been empty for a long time, and plumbing defects and leaks increase in likelihood in such homes, as well.
• Examine the landscaping. Left unchecked, trees can send their roots into the foundation, and vines can creep into the windows.
• Has the house been professionally inspected by an InterNACHI inspector? Foreclosures can be notorious for damage suffered at the hands of past tenants, through both inadvertent and intentional vandalism and theft.

In summary, there are a number of ways to go about buying a foreclosed home, and buyers should exercise patience, persistence and careful planning before buying foreclosed properties.
