Many homeowners wonder whether to replace or repair an HVAC system with the goal of saving money.

Before you make a decision, you must weigh several factors. The most important thing to consider is the lifespan of your existing HVAC system. Based on information from EnergyStar, an air-conditioning unit can last from 15 to 20 years. A heat pump lasts, on average, for 16 years while a furnace can function well for 15 years.

HVAC systems also require periodic and good maintenance to preserve function and prolong lifespan. Repairs are necessary from time to time but notwithstanding these efforts, there will come a time when a replacement becomes inevitable.

An air-conditioning or heating system can be costly to replace with a brand-new one. If you continue to repair a unit that has outlived its life, it becomes more expensive to operate and may be more prudent to replace.

Repair vs. replacement of an air-conditioning system

Technology has made many changes to cooling systems to take into account environmental factors. If a cooling system stops working properly or does not provide the normal amount of cool air, if may be better to get a replacement.

Below you will find several things to consider when choosing between repairing or replacing your air-conditioning system.

1. The unit’s age

It is important for you to consider the age of your cooling system. EnergyStar recommends that an air-conditioning system be replaced every 10 or 15 years.

If your air-conditioner is 9 years old, it isn’t a smart step to repair it unless it is a small fix. You should consult an HVAC company about your options.

2. Frequency of repairs

If your unit is less than 15 years old but already requiring frequent repairs, it may be better to get a replacement.

Calling in a technician every now and then is a hassle and causes a lot of inconvenience and discomfort on your part. The expenses due to repairs can also become costly if continually done.

3. Cost of the repairs

If you still can’t decide whether to repair or replace the unit and it is more than 10 years old, a brand-new unit may be a smarter investment. Consider the cost of repairing the unit a few more times versus the cost of a brand-new installation over the long-term.

Repair vs. replacement of a heating system

Every homeowner will experience a malfunctioning heating system. Is the heat suddenly not enough even when you hike up the thermostat? You may start to wonder if you should replace the unit or call in a technician to have it fixed.

Consider the following factors when making a repair or replace decision for your heating system.

1. Safety

If your heating system has become a hazard, it is a no-brainer especially if the repair will cost money and the fix is only temporary.

Faulty wiring or stuck valves may be easy to fix. Bigger issues with a furnace can lead to carbon monoxide leaks that could pose serious risks to your health.

Consult a qualified professional and perform a cost-benefit analysis to make a wise decision.

2. Age of the unit

How old is the unit? A furnace can last for 15 to 20 years. If your system is 20 years or older, it still does not mean it should be thrown out. The final consideration should be its current performance. If it is acting up and costing money to repair, it may be time to replace it as it may have outlived its usefulness.

3. Performance

If your heating system is not working properly, it will not heat your home well enough. A good indicator of trouble with your heating system is if some of the areas in the home don’t reach the temperature you desire. Thus, some rooms would be warm while others not warm enough.

Compare the repair and replacement costs a new boiler or furnace. If you choose to repair, keep in mind that the same issue may crop up and require more repairs in the future. If the repairs cost 50% or more of a replacement, it may be better to take the plunge and go for a new unit.
