Climatisation Davis offers installation, repair & maintenance services for:

The insulation techniques used to build many homes create environments that are air tight. This ends up trapping moisture and pollutants indoors, and as a result, no fresh air is able to get inside to create a balance, putting occupants and the house itself at risk. Proper installation and regular maintenance will prevent expensive repairs, continue the system’s efficiency and protect the health of your family.

Installed directly into your heating and cooling system, a whole-home humidification system introduces water vapor at the heating ducts, which is then controlled via your thermostat. Having the optimal level of humidity all year round can rid your home of low-humidity viruses and dry air that can aggravate asthma and skin irritations, and cause static shocks. Humidification can also help with energy efficiency, making you feel warmer at lower temperatures. There are numerous benefits, however humidification systems must be monitored and maintained as too much can create mold, water damage and health issues. Ideally, the humidity level should hover between 40 and 45%.

Generally, air filters reduce the amount of airborne particles, with some high-efficiency brands filtering out tobacco smoke, bacteria and various allergens. Filters also keep lint and other kinds of debris from plugging the coils of your heating/cooling system, preventing short circuiting, fires and general accumulation in ductwork. Climatisation Davis offers proper installation and regular maintenance which can prolong the life of your system as well as ensure quality air for you and your family.

These HVAC systems cool water through a chiller, which then cools coils or heat exchangers and your air is cooled when it absorbs energy. The warm water then returns to the chiller to restart the process. Regular maintenance of your water cooled system can reduce annual cooling cost by up to 40% as well as reducing dangerous emissions. Water cooled systems typically last longer than air cooled systems, however general maintenance is a key to that longevity.

You don’t like to be hot under the collar and no one knows that better than the professionals at Climatisation Davis. Whether you need your AC fixed, are searching for a more energy-efficient system or need an upgrade, we can help. Arranging intermittent AC maintenance also reduces your energy bill and helps prevent repairs caused by unmaintained systems. Setting up a routine check of your system is as easy as giving us a call.

Regular and efficient maintenance of your heat pump is the key to optimal operation; a well-maintained pump can provide you with energy savings of 10 to 25%. We can inspect and change your filters as well as clean coils and fans that are reducing air flow, decreasing your system’s performance and damaging the compressor. We can spot duct leaks, verify airflow, inspect electric terminals and lubricate motors, all to ensure that everyone in your home is benefiting from a high-functioning heat pump. We can also provide you with tips on how to operate your pump between our maintenance visits!

Pre-season, preventative maintenance of your electric furnace and duct heaters can help avoid a system failure when temperatures start to dip below freezing. It’s a sure way to save on your energy bill as well as a system that needs cleaning or a tune-up must work harder to heat your home, ultimately damaging your furnace in the long run.

A smaller unit offers flexibility for zoning or heating and cooling particular rooms, ultimately saving energy and money as it is only used when the space is occupied; however, if not properly maintained, mini split Acs can break down like any other HVAC system. At Climatisation Davis, we check the refridgerant, test for leaks, measure airflow, check the electrical controls, and more to ensure that your convenience is not being compromised.

Pool heat pumps might cost more at the outset but generally have operating costs that are much lower annually than gas heaters, providing the system is properly installed, especially the electrical hookup, and receives regular maintenance. Our service professionals will make certain that your heat pump is optimized for efficiency and longevity.

Your ventilation ductwork requires maintenance involving inspection and cleaning at regular intervals. Our professionals can provide deep cleaning of ductwork if necessary, safety inspections, filter inspection and cleaning, and more. By adopting low-cost preventative maintenance now, expensive ductwork repairs can be avoided in the future.
