San Rafael Air Conditioning Services
Keeping Your Summers Breezy
A large number of residences throughout Marin and Sonoma counties rely on air conditioning to keep them cool and comfortable when temperatures soar. The local area has many microclimates for a small county. On a hot day, temperatures can be 10 to 20 degrees hotter than other towns. Certain valleys or west-facing locations can be brutally hot on a summer’s day. Air conditioning has become more popular because people do not want to be uncomfortably hot in their homes. This is especially true for children or the elderly who may face health hazards as a result of overheating.
John Owens Services, Inc. has been providing air conditioning installation, repair, and maintenance in San Rafael and the surrounding areas for decades. Let us help you stay cool all summer long. We handle all cooling system makes and models and ensure fast, reliable services at competitive rates every time.

Types of Air Conditioners We Service
The most common air conditioning system in San Rafael and throughout Marin and Sonoma counties is a split system comprised of a gas furnace, an indoor evaporator coil, and an outdoor condensing unit. The two split parts of this type of AC are connected with a copper refrigerant piping. The sequence of operation starts with the thermostat calling for cooling, the furnace blower motor will then provide the airflow. Next, the evaporator coil absorbs the heat from the air and the outdoor unit dissipates the heat into the outdoor.
In addition to servicing conventional split AC systems, we also handle the following:
- Split systems with air handlers – For a home with radiant floor heating throughout and requires air conditioning to the second floor, a split system with an air handler is a good option. The air handler serves as the indoor unit that contains the evaporator coil and the air blower while the outside unit contains the condenser. The two units are connected with copper refrigerant piping.
- Rooftop package units – These ACs are used mostly on commercial rooftop applications. A package unit has the gas furnace, evaporator coil, and condensing unit built into a pre-assembled, factory-built unit. They are on the roofs of some buildings and, in certain applications, sit on the ground adjacent to the home. This type of equipment can be useful for properties that have no attic or crawlspace to accommodate heating or cooling equipment.
- Mini-split or ductless air conditioning systems – As the name implies, these ACs need no ductwork. They are used to spot heat or cool one room or can be combined to zone heat or cool an entire house. Mini-split systems are best on Eichler homes where there is no attic or crawl space. Mini-splits are also a great alternative to noisy window air conditioners.
- Ground-source or geothermal heat pumps – A heat pump is an air conditioner that is reversible. When a heat pump is in air conditioning mode, it extracts heat from within the home and dumps it outside. In heating mode, the ground-source heat pump extracts heat from the ground and transfers it into the home’s duct system or radiant heating system. This type of system is very common in climates that have extremely hot summers and very cold winters.
- Evaporative coolers (also known as swamp coolers) – These are generally roof-mounted and are very common for mobile homes and busy high-volume restaurants or restaurant kitchens. Because the cooling is created by evaporating water over filter pads, the air entering the building has a high moisture content.
Installing & Repairing Air Conditioning
Some of the most common issues we handle include:
- Refrigerant leaks
- Dirty condenser coils
- Frozen evaporator coils
- Faulty motors
- Fan problems
- Clogged drain line
We only suggest a new AC when the old unit is already more than 15 years old and costing you more money because of frequent repair needs. We are a proud Trane dealer and can help you select a more reliable and energy-saving air conditioner. We also ensure proper installation, so you can get the most out of your cooling system.
Air conditioning technicians need to be highly trained and certified to handle refrigerant gases since they are controlled by the Clean Air Act. The main job of the Clean Air Act is to set forth proper procedures for dealing with refrigerant gases. The procedures affect the storage, transfer, removal, and recycling of potential Ozone-depleting gases.
John Owens Services, Inc. has been EPA refrigerant gas certified since 1994 and has maintained an impeccable no-violation record with the EPA for over 20 years. Safety and training are the keys to maintaining good refrigerant gas management.
Annual Preventive Maintenance Is a Must
It is important to do a thorough annual inspection, maintenance, and testing of your air conditioning system before the hot weather or heatwave is upon us. There are a very limited number of qualified air conditioning technicians in San Rafael. If your air conditioning breaks down during a hot spell, it could be days before a technician could become available. We and all other air conditioning contractors run waiting lists during hot spells. Don’t be caught out—call us and book an air conditioning maintenance as soon as you can.
Our AC maintenance checklist includes:
- Checking the outside of the condensing unit for dirt and debris
- Checking inside the evaporator coils for debris buildup or a loose or incorrectly positioned thermal expansion valve sensor
- Verifying the refrigerant charge
- Testing for proper and safe operation
- Inspecting the relays, contactors, and capacitors for signs of wear
- Checking and cleaning condensate drain
- Checking and replacing air filters
- Recording temperatures and pressures for each system to help us diagnose future problems
