Residential Systems
Installation, repair and maintenance for the air conditioner at your house. A unit that runs but won’t cool, short-cycles, or ices over is a repair call; a unit that has become a repeat visitor may be a replacement conversation.

AC Check-ups
A technician looks over the system before the first hot week, so a weak part gets found on your schedule instead of in the middle of a heat wave.
About AC check-ups“Good professional work done at a fair price. They worked clean and efficient. The only way you knew they had been here was the fact that the house was cooler.”
Maintenance programs
What a check-up looks at before the first hot week
In general, a cooling check-up is a technician going through the parts that fail first. Johnson offers check-ups and maintenance programs for residential and commercial systems.
- Condenser coil
- Dirt and pollen on the outdoor coil make the unit work harder to shed heat.
- Line set insulation
- Torn foam on the copper lines wastes cooling before it reaches the house.
- Capacitor and contactor
- Small electrical parts that wear out and keep a compressor or fan from starting.
- Condensate drain
- A clogged drain line can back water up into the air handler.
- Filter and airflow
- A clogged filter starves the system of air and can freeze the indoor coil.
- Thermostat
- Settings, wiring and whether the system actually answers when it is called.
Heat pumps run the same cycle backwards in winter.
