REPOST: Updating your cooling system is a smart investment

The average useful life expectancy of an air conditioning unit is 10 years. To keep it running efficiently, regular maintenance is a must. Chron tackles the importance of updating air conditioners below.

If you’re a seasoned homeowner, you know houses require a lot of upkeep. Experience also shows the best home projects offer a dual advantage: they add to your quality of life and to your home’s overall value. And if an improvement helps save money in the long run? That’s a triple win!

Dave Borowski, spokesperson for Direct Energy Protection Plans, says updating your cooling system can offers these benefits: “The useful life expectancy of an air-conditioning unit is usually seven to 10 years — much like a car, it might keep running but not as efficiently. And professional maintenance can increase the product’s life expectancy, improve performance and help reduce the severity and frequency of breakdowns.” So if you do plan to update your home’s cooling system, here are tips to ensure that investment pays off:

Find a good contractor. Look for the best credentials, not the best price: “A questionable contractor can cut the cost, but he may also cut corners,” warns Borowski. A NATE certification (National Alliance for Technical Education) is one standard of quality. Referrals — from online sources, and from people who had AC units installed 10 years ago or 10 days ago — can tell you a lot about contractor’s workmanship over the short- and long-term. “The most important day in an air conditioner’s life is Day #1, when it’s installed,” notes Borowski. “If it’s not perfect then, it will never get better.”

Buy the highest efficiency unit that you can afford. Face it: Electric rates are not likely to go down. Spending a bit more for an energy-efficient unit can actually lead to long-term savings.

Ask about rebates. Many vendors seasonally bring out rebates to help boost sales; check with your contractor to see if there are good deals out there.
Make sure your ductwork is properly sized for your air conditioner. “Just because your ductwork is there – and has been there for 22 years – doesn’t mean it’s right,” explains Borowski. An improper fit means the unit won’t work as efficiently as it should. A good contractor will check this, but it never hurts to bring it up.

Get a programmable thermostat. The newest versions let you monitor the AC right from a smart phone: “With the Comfort Sentry ThermostatTM, you can control the temperatures and set schedules to fit household needs,” says Borowski. To save energy — and energy dollars — you can raise the temperature during daytime hours when no one is home, and have things cool down automatically by 5 p.m. “Or suppose you’re at the airport, ready to go on vacation, and suddenly realize, ‘Ugh, I forgot to turn the thermostat off! It’s going to be cooling the house for two weeks while we’re on a cruise.’ Now, all you’ve got to do is go to your smart phone and put the thermostat in ‘vacation’ mode. Running the AC when you’re gone is equivalent to running ceiling fans when you’re gone!”

Check the service options. Even the best-installed air conditioner can break down; find out when your contractor does warranty service. “Some only do it Monday through Friday, 9 to 5,” says Borowski. “Imagine if your air conditioner breaks down at 5:15 on a Friday, and your contractor says he’ll be happy to help you Monday morning! Make sure you’ve got someone who stands behind his work and will perform warranty service 24/7. If not, you’ve got the wrong contractor.”

Heating and cooling systems for underground shelters

Nuclear threats, extreme weather, and doomsday predictions – people can never tell when they’re going to happen, but they can always prepare for the worst rather than be sorry.

One of the options people could take is to build an underground shelter, at least 8 feet deep, adjacent to the occupants’ house, and equipped with the necessary survival kits and proper ventilation.


The chapter on Nuclear War Survival Skills of the book Fighting Chance: Ten Feet to Survival by Eugene P. Wigner notes that one of the most significant survival skills that people should learn is “how to keep occupied shelters adequately ventilated in all seasons and cool enough for many days of occupancy in warm or hot weather.”

The author recommends using a large-volume shelter-ventilating pump, an expedient heating machine which doesn’t require ample technical know-how to build. The book shows how to build the machine using inexpensive household materials.


Another heating systems option is to use geothermal heat pumps run by electricity generated through solar power. Builders may need to hire a professional to set up the heat pumps. Heating and systems contractors, like Hobson Air and A Plus Quality Inc., can provide necessary assistance. Adequate ventilation is still required during freezing weather conditions as the earth’s moist will continue to absorb body heat, leaving the occupants prone to weather-related illnesses.


Natural ventilation can be achieved by following the structure of an Eskimo igloo. The spiral dome is built with small ventilation openings poked at the ceiling and at the floor to protect its occupants from harsh temperatures. A shelter with a chimney-like vent is proven to be useful during cool weather, supplying occupants with enough air needed to prevent the build-up of carbon dioxide. However, it should be noted that this vent may not work during warm weather.
