Determining whether to repair replace an old heating and air conditioning equipment can be difficult. However, having changed/repaired numerous systems, we have some guidelines to help you make this decision.
Life Expectancy of Current System
When you’re frustrated with an equipment break-down, it can be tempting to find the least expensive “quick fix” to get on with your life in relative comfort. That “quick fix” may be the least expensive now, but it may not give you the most value — or cost you the least — in the long run.
Paying for repairs to an old or inefficient system often simply prolongs the inevitable. It’s almost like putting a bandage on a serious injury. An older system that breaks down once is likely to break down again … and again. That means more emergency service calls or, worse yet, the risk of damage to your home or to other components of your heating and cooling system.
There’s also an ongoing cost factor to consider. Restoring your old system will only bring it back to its current level of energy efficiency. After you’ve recovered from the repair bills and the frustration of system breakdowns, you still won’t save on your energy bills.
Even six-year-old heat pumps and air conditioners are considered grossly inefficient by today’s energy efficiency standards. So are most furnaces built before 1980. So you could save up to 60% on your energy bills with new high-efficiency equipment. That’s why installing a new heating and cooling system can actually pay for itself in energy savings within a relatively short time.
Looking at the Big Picture
When one component of your system breaks down unexpectedly, it’s easy to just focus on repairing or replacing that component. But each part of your system works with the others to boost efficiency and reliability, so it helps to keep the big picture in mind.
Replacing your old furnace with a new higher-efficiency model but leaving your old mechanical thermostat in place, for example, won’t allow you to enjoy all the efficiency advantages the furnace has to offer. Likewise, if you install a new furnace but don’t get a humidifier, the air may seem cooler, forcing you to operate your new system at a higher temperature to be comfortable. Plus, you can often save on installation costs if you have several components of your system (for example, a furnace and an air conditioner) replaced at the same time.
Routine maintenance on your heating and air conditioning equipment can save you a lot of money and frustrations. Just as you need your car running at all times, you should plan and schedule regular maintenance.
In the spring, Norman Heating & Air Conditioning can typically check a heat pump or air conditioner for all or some of the following:
- operating pressures
- refrigerant charge
- filter condition
- fan motor
- crankcase heaters
- coils cleaning
- lubrication of moving parts
In the fall, you can expect Norman Heating & Air Conditioning to check your furnace in the following areas:
- burner and pilot assemblies
- cracks in the heat exchanger
- check the pilot thermocouple
- examine the filter and check vent piping
- test the electronic ignition
- test the fan
- test the limit switch
- burner adjustments
- measure manifold gas pressure
- measure temperature rise
- carbon monoxide test
- set the heat anticipator
- check and adjust belt tension
- examine the draft diverter
- lubricate the fan motor
