How Long Should a Furnace and Air Conditioning Unit Last?

Darren Kincaid - Monday, January 08, 2018

Central Plumbing and Heating, Chesapeake, VAToday's heating, ventilation and air conditioning units are more energy-efficient than their predecessors.

New air conditioning and heating equipment lasts longer than ever. The end of a furnace's or air conditioner’s service life depends on more than just chronological age. Energy-efficiency issues and the price of any necessary repairs versus the cost of upgrading to a new unit all enter into that determination.

Furnace Lifespan

The average service life of a new furnace is 16 to 20 years. Most furnace parts that fail during that span are replaceable at a cost that makes repair a better call than replacing the entire furnace. The exception is the heat exchanger, a furnace's single most expensive component. A cracked heat exchanger in a unit that’s already out of warranty is usually a tipping point that means it’s time to shop for a new furnace.

Central Air Conditioners

Central air conditioners typically last from 12 to 15 years. The lifespan of a central cooling unit may be reduced if its capacity is not properly matched to the cooling load of the home. Oversized air conditioners “short-cycle,” turning on and off rapidly, inflicting excessive wear and tear on the compressor. Like the furnace heat exchanger, the compressor is the most costly part in the system. A worn-out compressor in a unit that’s outlived its warranty is usually a deal-breaker that warrants upgrading to a new, more energy-efficient air conditioner rather that repairing the existing unit.

Gas Water Heater Repairs

Darren Kincaid - Monday, December 04, 2017

Home heating systems need maintenance, repairs and upgrades periodically. This is less challenging than a bathroom or kitchen upgrade, but in many cases, these types of jobs often require a specialist.

Most repairs to a gas water heater are made at the burner control. If your heater leaks, the tank is rusted through and the entire unit must be replaced. Call a HVAC specialist to replace a gas water heater.

Below is a quick troubleshooting guide to gas water heater problems:

If the unit suddenly stops heating water, try relighting the pilot. If it does not stay lit, the thermocouple probably needs to be replaced. If that does not solve the problem, you may need to clean the burner.

If the flame is mostly yellow rather than mostly blue, clean the burner.

If water isn't heating sufficiently even though the thermostat is turned up and the flames are blue, drain the tank and refill it.

If you have hard water, unscrew and remove the anode rod once a year. Look for a 1-inch nut in the top of the heater. Loosen the nut; the anode rod will be attached. If it's encrusted with minerals, replace it to get more efficient operation.

For any of the above tasks, if you are uncomfortable, contact Central Plumbing and Heating.

Pressure-Relief Valve

A temperature- and pressure-relief (TPR) valve is a safety device that provides an outlet for water in case the unit overheats. To test that it's working, pull up on the little lever; water should flow out. If not, or if water drips from the valve, the TPR valve needs to be replaced. Contact Central Plumbing and Heating.
