What you should expect your service technician to do during a service call.

A lot of people ask us about the procedures that our technicians actually follow when they go out on annual tune-up and cleaning of furnaces and central air conditioners. The following is actually a checklist of (in broad terms) what our techs do when they come to your home:

Outdoor Units

  • Inspect unit for proper refrigerant level and adjust if necessary.
  • Clean dirt, leaves and debris from inside cabinet.
  • Inspect base pan for restricted drain openings – remove obstructions as necessary.
  • Inspect coil and cabinet – clean as needed.
  • Inspect fan motor and fan blades for wear and damage – on older models lubricate as needed
  • inspect control box, associated controls / accessories, wiring and connections. Controls may include contactors, relays, circuit boards, capacitors, sump heat and other accessories. All control box and electrical parts should be checked for wear or damage.
  • Inspect compressor and associated tubing for damage

Indoor Units

  • Inspect and clean blower assembly (includes blower housing, blower wheel and motor).
  • On older models, lubricate motor and inspect and replace fan belt if neede.
  • Check combustion blower housing for lint and debris and clean as necessary.
  • Inspect evaporator coil, drain pan and condensate drain lines. Clean as needed.
  • Inspect for gas leaks in furnace.
  • Inspect burner assembly – clean and adjust as needed.
  • Inspect ignition system and safety controls – clean and adjust as needed.
  • Inspect heat exchanger or heating elements.

AC Service

★★★★★
5 5 1
Every aspect of working with Cozy Comfort Plus has been perfect. The company calls and schedules our appointment (I don't have to worry about when I need to have it done) and they are work with my schedule, even when I have to change it last minute. The technician gave me a 45 minute warning which allowed me to walk my new dog and have her tired and relaxed before he arrive (thank goodness). When he arrived he was curtious and provided me with great information that I didn't even know about my machine (winter/summer mode switch) the need for me to change my filter more often now that I have a dog that sheds (all our other dogs never shed so I didn't even think about it until he showed me the filter (wow this dog sheds), he also showed me what could happen to your AC if it isn't looked after...wow I am so glad they service my AC it certainly will have a much longer life! Thanks so much for the kind, friendly service, teaching me about my Furnace and AC and how to keep my house cooled properly , efficiently and at a cost savings (cooling my house and having a longer lasting AC) The technician also explained the bill to me and had no problem adding an extra filter when I notice that they weren't that expensive, now I have one to easily change if I find the pets are making it necessary. Thanks Cozy Comfort Plus for an awesome inspection!
