As air passes through these vents, it drops the temperature of the air before it blows out into the vehicle to cool the cabin. A blow motor pushes air from the cabin, or from outside, through vents in the evaporator core. The cold freon then chills the evaporator core as it circulates through. As freon is passing through the expansion valve or orifice tube, this is where the freon pressure and temperature drops right before going through the evaporator core. It will then pass through the expansion valve or orifice tube. This is a maintenance checklist form to periodically inspect HVAC products. The freon will pass through the receiver/dryer or accumulator where contaminants and moisture are removed. An HVAC maintenance checklist is a list of general tasks that describe the adjustments and procedures that should be performed on a regular basis on heating, ventilation, and air-conditioning systems. It loses heat as it flows through the condenser. When the compressor is turned on, it begins to compress the system’s refrigerant (freon), raising its temperature. A/C in vehicles works by removing heat and humidity from inside your car. You can also get the vehicle inspection service at Droom.A good A/C system is life saver in the sweltering months of summer. That is the reason Droom has come up with these tips and ask each and every car owner to take care of their car and do a little DIY, as it will save their pockets a lot. Maintenance of a car AC is pretty simple and keeping a note of these tips and maintaining can actually do wonders to its life span. After a minute or so, close the windows and enjoy the cold air. This would get rid of the hot air trapped inside faster. If your car is exposed under the sun for a long time, turn on AC for a couple of minutes with the windows OPEN. Before starting your mini-split AC maintenance routine, switch off the unit and turn the power off at the breaker to prevent electric shocks. This ensures its long life and also saves you from any AC malfunctioning. Use this simple maintenance checklist to keep your air conditioner in working order between professional services. Handle with care:ĪC functions has to be used gently. Focus on recirculation:Ĭhoosing the recirculation mode would save you a lot! Your AC compressor will thank you for letting it go easy and as compared to cooling fresh air, maintaining the temperature of already cooled energy takes much lesser energy and less strain on the compressor. The AC compressor, pipelines, and drive belts should be kept well lubricated to prevent any AC’s malfunctioning. Droom ask to focus on these DIY activities. Maintenance of the AC gas pipelines would take you a long way! Cleaning the pipelines once a week would keep them clean and let you know of any leakages. Getting them checked at a service center might save you a lot of time and money. They might be indicating serious issues with the compressor or even with your car itself. Ignoring any strange sounds coming from the compressor is not a good idea. Your car tries to communicate with you in the form of sounds. Hence, you should check these small belts and hoses during the starting phase of the summer itself. Often in hot weather, excessive heat and a lack of proper lubrication may cause the compressor to operate less efficiently. The car AC compressor is driven by a belt, operated by the car engine. This degrades the quality of cooling it provides. Depending on your car and what kind of oil youre using, you may need to change both the oil & oil filter as much as every 3 months or 3000 miles. The car engine’s radiator needs your attention too! It is often seen that if the engine heats up too much, the heat travels from the radiator to the AC condenser. Have you ever thought dust can be a reason? But it is. Even if your air filters are clean enough, the AC duct might attract dirt and moisture from the car’s insides, causing a blockage. Checking The Engine Fan and Fan Belt The next item on our list is checking the engine fan which can be mechanical or electrical. While taking care of your car’s insides, make sure to get rid of the dirt and dust as much as possible. Make sure to wash the air filters thoroughly at least once a week to keep them clean and cool.
