The TDH Mechanical Guarantee

We’ve been the trusted choice for Chicago area HVAC services for nearly 30 years.

No Nonsense Warranty

Common Sense Advice & Notes:

  • The manufacturer recommends annual professional maintenance to help maintain peak performance & extend equipment life. We think it’s a good idea; however it’s not required to maintain your warranty. If you choose maintenance it’s 185 annually for a fall furnace visit/spring air conditioning visit.
  • Keep your indoor filter & outdoor unit coil clean. Equipment failure due to dirty filters or coils will result in a standard cleaning charge.
  • Damage beyond our control isn’t covered, i.e.; Flood, Fire, Hail, Hit by car, baseball bat etc.
  • Warranty coverage is transferred to future homeowners for FREE.
