Frequently Asked Questions



What is the $5000 rule for HVAC?


The $5,000 rule is a general guideline used to decide whether to repair or replace your HVAC system. Multiply the age of your system by the cost of the repair. If the total exceeds $5,000, replacement is typically more cost-effective. For example, a 10-year-old system needing a $600 repair = $6,000. In that case, it may be time to consider a replacement.


What are the most common HVAC repairs?


The most common HVAC repairs include:

  • Replacing or cleaning dirty filters

  • Fixing thermostat issues

  • Repairing or replacing worn-out capacitors

  • Clearing clogged condensate drains

  • Recharging low refrigerant levels

  • Replacing broken fan motors


These are typically routine and can often be handled same-day by a qualified technician.


Which HVAC brand lasts longest?



Brands known for durability and long life include:

  • Trane

  • Lennox

  • Carrier
