When Is It Time To Replace An HVAC System?

Repairing Your Air Conditioner or Heater vs. Replacing

Repairing Your Air Conditioner or Heater vs. Replacing It – If your heating or air conditioning system isn’t working at optimum efficiency or fails occasionally you are faced with a choice, to repair the existing unit by replacing parts or by buying a new air conditioner or heater.

Some air conditioning and heating companies try to sell home owners certain solutions based on what is convenient or what earns them the most money. Not TSC Air. We don’t operate like that at all.

Don’t be pressured into making a snap decision, first get the facts from TSC. 

What to Consider

You should decide whether to repair or replace a unit based on what is in your best interest. To help with this important decision we have gathered this important information for you to know.

The Three Main Factors

  • When considering whether to replace your existing unit the three main factors to consider are the life expectancy, efficiency, and current condition of the unit.
  • Each must be considered carefully before you decide whether to repair or replace your air conditioning or heating unit.
  • If any of these factors is a problem area then you should consider replacement and if two or three are problems then replacement is almost always your best bet.

Life Expectancy

Most heating and air conditioning systems last about eight to twelve years, after that point they become expensive to repair and can break down often. Older systems are also at risk of discontinued parts which causes them to be more expensive if not completely unavailable.

If you live in an area near the ocean or with a high salt content the life span of your unit may be even shorter due to corrosion. Consider the age of your equipment when you decide whether to replace or repair your air conditioning or heating unit.

  • Did you know… You can add up to four more years of life to your hvac system if you have a professional system maintenance performed on a regular basis. Learn more about HVAC Maintenance >> 


If you completely restore an aging unit, which is expensive to do, you will still only have the efficiency that it was rated for when it was manufactured at best. Older units are much less efficient that newer ones due to constant improvement and increasing energy standards imposed by the government so replacing your unit can save you money if your units is old and inefficient.

Current Condition

Consider the current condition of your unit when you decide whether to repair or replace your air conditioning and heating unit. Factors to consider are the quality of the equipment (reputable brand, builders model, etc.) number of breakdowns and how often the unit has been maintained. If your unit hasn’t been maintained or is an inferior quality or has frequent breakdowns consider replacement as a serious option. No matter the skill of the installer or service professional there is little that can be done with a unit that is in very poor condition besides restoring the unit which is almost always prohibitively expensive.

Matching Systems and other Pitfalls

Whenever your condensing unit goes out – most professional air conditioning technicianswill recommend that you replace your indoor air handler at the same time because the two units must be matched so that your new outdoor unit can work at maximum efficiency.

Improperly matched units will shorten the life span of your new unit. This is just one of the many pitfalls that need to be avoided when replacing a system. Do not make a serious mistake when buying a system.
