How Old is Your HVAC System?


The age of your HVAC Unit is one of the most obvious factors to consider and should be the first question asked by an HVAC company when helping a customer assess their current air conditioner or furnace.  The age of your HVAC system extends beyond just the average wear and tear over the years.  Most of the older HVAC units run off of r22 refrigerant which is currently in the final stages of being phased out.  This has led to drastic price hikes in basic maintenance hard costs which will only continue to make maintaining your HVAC system more expensive over time.

  • Under 12 Years Old:  REPAIR
  • Over 12 Years Old:  REPLACE

What Type of Problem is Your HVAC Unit Currently Experiencing?


Not all HVAC repairs are created equal.  The extent of your systems problem can largely impact the average consumer’s decision to replace or repair your HVAC equipment.  Minor problems can cost a fraction of the out of pocket expenses that a major repair could cost.

  • Minor Problems (Broken Ductwork, Clogged Drain Line, Electrical Issues):  REPAIR
  • Major Problems (Broken Blower Motor, Compressor, Condenser Coils):  REPLACE

What is the Total Estimate of your HVAC Repair?


Considering the cost of a new HVAC unit vs the cost of the HVAC repair should be viewed similar to how car insurance companies deem a vehicle totaled if the estimated costs exceed the value of the car.  However, unlike cars, your HVAC system can be a money saving investment over time, and with the latest advances in energy efficient systems, measuring the cost of your HVAC repair can be crucial in deciding whether to repair or replace.

  • Cost of repair is less than 50% of new HVAC unit (and/or is still under warranty):  REPAIR
  • Cost of repair is MORE than 50$ of new HVAC Unit (and is NOT covered under warranty):  REPLACE

What is the Efficiency of your Current HVAC System?


There has recently been a massive upgrade in the efficiency of the average air conditioning system.  Knowing what your air conditioner’s current SEER level is crucial when measuring whether to repair or replace.

  • Current Unit Has a SEER Level of 13 or Over:  REPAIR
  • Current Unit Has a SEER Level or 12 or Under:  REPLACE

How Many HVAC Repairs Have You Experienced over the Life of Your Unit?


often as an air conditioner gets older, the frequency or air conditioning repair increases.  Try and keep records of your systems maintenance history and use it to help assess whether it makes sense to repair or replace.

  • Less than 2 Repairs over the Last 10 Years:  REPAIR
  • Over 3 Repairs on the Same HVAC Unit:  REPLACE

What is the Size of your Current Air Conditioner?


It is very common for homes to have the wrong sized unit for various reasons.  It is important to know what the correct sized AC Unit is for your home’s square footage.  An undersized unit can be extremely under efficient while an over-sized AC unit can often lead to poor humidity control and shorter lifespans.

  • Correct Sized Air Conditioner:  REPAIR
  • Over or Under-Sized Air Conditioner:  REPLACE

What is Your Current Credit Score?


Most HVAC companies over a variety of different financing options for customers seeking to install a new air conditioning system.  However, just like all financing, the better your credit history is, the better your lending terms will be.
