Repair or Replacement?

Not sure if you need a furnace repair or replacement?  In many cases, people prefer to repair instead of replace.  Most furnace problems can usually be repaired.

As a well-established and trusted HVAC company, Hellas Air Temp will always strive to provide the simplest and most suitable solution for you – if a repair can be made and it makes sense, we’ll do it.

Higher Energy Bills

As furnaces age, they can become inefficient, wasting energy and costing you more money.  If you notice an increase in energy bills a repair can sometimes solve the issue.  If you need to keep paying for repairs, however, a replacement may be more suitable.

Abnormal Noises

Furnaces can make a range of noises when they have a problem.  From murmurs to clangs, knocks and squealing; these can all indicate that something is loose or broken.  Depending on the type and severity of the noise, a delayed repair can sometimes lead to further damage and the need for a total replacement.

Irregular Cycling

Does your furnace constantly turn on and off? Sometimes this is simply an issue with the thermostat which can be simply fixed; other times irregular cycling can indicate a furnace that is struggling to keep up with demand and nearing the end of it’s life.

Regular Maintenance Saves on Repair Costs

Most furnaces can benefit from a yearly inspection and maintenance service to keep them running efficiently and help prevent repairs.  This is also recommended by the Government agency Energy Star.  They also recommend “Contractors get busy once summer and winter come, so it’s best to check the cooling system in the spring and the heating system in the fall.”
