San Antonio HVAC Repair vs. Replace?

  Many San Antonio home owners struggle with the dilemma of whether to repair or replace their current air conditioning system.  Obviously, if the cost to get the unit back up and running is minor, then that may be a good option, but here are some factors you should consider before investing more repair dollars into your existing unit.

Heat pump or air conditioner is more than 10 years old.  Consider replacing a HVAC unit that old with a high-efficiency model.  Installed correctly, high-efficiency units can have a dramatic impact on your electric bill and actually pay for themselves over time.

Equipment needs frequent repairs.  Frequent repairs are a sign that your old unit has reached the end of its life and is just worn out.  Continuing to pay for more repairs is only prolonging the inevitable.  The sooner you replace a unit in this condition, the sooner your energy bills will improve, which can end up paying for the new system and saving you money in the future.

Energy bills are very high.  Your air conditioning system makes up as much as 60% of your utility bill each month.  Older, inefficient systems use more electricity to deliver the same comfort level as current high-efficiency units do.  It is not uncommon for our customers to report dramatic drops in their energy bills after we install their new system.  Although each home is different, 50% reductions in utility bills (from the same time period during the previous year) have been reported.

Some rooms are too hot or too cold.  These kinds of problems are usually the result of an improperly engineered system when the home was built or when the last unit was installed.  A well trained technician can diagnose hot/cold spots in your house and determine if the problem is related to the unit's size (tons), inadequate insulation, improper duct work or some combination of these.  You definitely want to have a Jon Wayne technicians perform a Complete Home Evaluation to make sure these problems are dealt with properly.

Home has humidity problems.  Poor equipment operation, inadequate installation, improperly sized unit, and leaky ductwork can all cause the air in your home to be too dry in the winter and too humid in the summer.  Again you will want a Jon Wayne technician to perform a Complete Home Evaluation to determine the cause and eliminate it completely.

Home has excessive dust.  Leaky ducts can pull particles from your attic and crawl spaces and distribute them throughout your home.  Sealing existing ducts or, if the duct work in your home is in poor condition, replacing your ductwork can be beneficial.

Heating and cooling system is noisy.  Noisy units can be caused by a variety of factors including an undersized duct system or a problem with the indoor coil of your cooling equipment.

No two homes are exactly alike and as such, the only way to really know if repairing your HVAC system is the best option is to have a qualified Jon Wayne Comfort Advisor evaluate your home and explain to you their findings.  In addition to a visual inspection of your equipment and attic space, we will also perform a Manual J Load calculation which uses information about your San Antonio area home (overall dimensions, window location, orientation to the sun, etc.) to determine the proper equipment needed to cool your home most efficiently.  If serious issues exist (like rooms too hot or cold) we can perform a Blower Door Test which simulates pressure within your home and uncovers problems areas so they can be resolved.
