HVAC Technician's Best Tools and Accessories


Top HVAC Tools: Quality Selection


Leak Detector

HVAC repair technicians use leak detectors to validate regions with moisture to pinpoint the leaking source better.

Coil Fin Straightener

When air conditioner condenser coils become unclean, clogged, or twisted, a coil fin straightener aids in the removal of debris. Service technicians use this air conditioning tool to straighten and clean coils to increase heat exchange and air movement. These air conditioning tools are both affordable and practical.


In the HVAC industry, temperature management is crucial. To comply with your state's standards and provide excellent customer service, invest in a portable, effective, long-lasting digital thermometer.


HVAC contractors consider a reciprocating saw blade the ideal saw for cutting through materials in most HVAC operations. To avoid dull blades, you must replace the blades regularly.

Caulking Gun

You can use a dripless caulking gun to seal air ducts and fill holes as needed. To avoid future disasters, ensure your caulking gun is in good operating order.

Thermal Imaging Tools

HVAC technicians must diagnose complicated problems for clients using only the most basic information available. Thermal imaging cameras, an important HVAC tool, allowing technicians to detect and correct root issues quickly.

Common HVAC Replacement Parts and Accessories


Best HVAC Equipment Picks


Maintaining the condition of your HVAC system may necessitate the replacement of outdated parts that have failed or are about to fail. Fortunately, your technician can typically detect these deteriorating parts before they cause major problems if you keep up with regular maintenance. On the other hand, which features are most likely to require replacement? Some of the most popular HVAC replacement parts are listed below.

Capacitors and Contactors

The start capacitor is responsible for turning the system on, while the run capacitor is responsible for keeping it running. To put it another way, it's the most important of the HVAC replacement parts. The contactor regulates the flow of electricity to the components of the unit. They're crucial, and they're also the components of your system that are most prone to fail. Fortunately, they're not too costly to replace.

Blower Motor

Your blower motor may burn out if your system works continuously throughout the season. Replacement is a reasonably common occurrence. Your technician will usually discover if your fan is worn out during annual maintenance and replace it before it breaks.

Evaporator Coils

Dirt and debris accumulate on your coils over time. They will last a long time if you clean them regularly. They can corrode and need to be replaced if they aren't cleaned. There is also a loss of refrigerant as a result of this.


The compressor is the most costly component to replace in an HVAC system. It's perhaps one of the most crucial components. Its failure could lead other parts of the system to fail. If your HVAC system is eight years old or older, purchasing a new unit rather than replacing the compressor is likely to save you money in the long term.

Air Filters

Your air filter, which is slightly different from the other HVAC replacement parts on our list but no less necessary, should be checked regularly and replaced as needed every three to six months. The filter will become clogged if it isn't, preventing airflow from entering your home. As a result, the system uses more power and wears down more quickly, resulting in costlier repairs.

Important HVAC Parts and Accessories of your Aircon

The compressor, condenser, and evaporator are the three major components of most air conditioners. These components work together to keep the air cool. As a result, their repair costs are also rather substantial, and DIY repair is not recommended. Learning how these parts work and how to repair them, on the other hand, should aid you in detecting problems before they cause serious harm to your equipment.


In the overall cooling system, the compressor is crucial. The compressor removes the heat from the air and expels it to the outside, letting cooled airflow within your space. It accomplishes this by converting the gas refrigerant that circulates through the interior components into a liquid, thus releasing heat into the atmosphere.

The compressor is a complicated component inside the air conditioner that must be tested and maintained by a professional every few months. In this instance, do-it-yourself repair and maintenance are not recommended.


The condenser is another crucial air conditioning component that absorbs heat from the unit's interior and helps to transmit it outdoors. The condenser is made up of hollow coils, and as part of the cooling process, refrigerant gas proceeds to the condenser and enters the coil.

Moisture in your air conditioner could react with the compressor coils to generate a corrosive material, causing damage to the condenser and other components of your air conditioner. It's a serious problem that professionals can only handle. To remove the corrosive acid, technicians will utilize a chemical cleaning method. They may, however, require you to replace any internal aircon parts if the damage is severe.


In the final step of the cooling process, the evaporator is used. The refrigerant in liquid form travels from the condenser to the evaporator, where it is converted back to its gaseous state, resuming the cooling cycle.

Even though the evaporator coil is not exposed directly to dust and filth, dust particles can collect over time. When dirt gathers on the evaporator coil, it starts to run slower and less efficiently, consuming more electricity. Cleaning it using a vacuum cleaner regularly is critical. Cleaning the aluminium fins with a soft brush would also be beneficial—but be cautious because the thin fins are prone to breaking!

Other Minor Parts of an Aircon Prone to Damage


Essential HVAC Gear and Accessories


Expansion Valve

The expansion valve regulates how much liquid refrigerant gets into the evaporator. A professional should examine a complicated air conditioning component every few months.


There could be an issue with the filters if you've lately discovered that your air conditioner isn't cooling the space as well as it used to. Dirt and dust will build upon the filters if you don't clean them regularly, preventing cool air from entering the evaporator coil. You can take care of this yourself by washing the filters with water and a mild detergent once a month.


Thermostats are sensors that allow you to set the temperature of a room to your preference. The air conditioner will keep cooling until the temperature gets to the setting you put on the thermostat. When the room temperature drops to that level, the thermostat's sensor will alert the air conditioner, and the AC will turn off for a period. Once the air temperature inside the room rises, the AC will turn on again.

Because the thermostat is a technical part of your air conditioner, it should regularly be maintained by a professional.


The muffler, one of the most underappreciated air conditioning components, controls the sound that the compressor makes while it's running. The muffler is vital because it allows you to enjoy a pleasant temperature while remaining silent. The compressor's original sound will be exceedingly loud and consequently extremely irritating.

When the aircon becomes noisy, you'll know that you must replace the muffler. Make sure an AC professional checks it every few months.

Drain Pipes

A major reason for aircon failure or poor cooling is the clogging of the drainage system. It occurs when dust particles gather in drain channels over time, causing a clog in the drainage system.

When there is excessive dampness in your rooms or the AC unit leaks, you'll know there's a problem with the drain pipes. To clear the clogging in the drain tubes, an air conditioning service technician will use a chemical cleaner.

If the drain channels aren't too blocked, you can clean them yourself by passing a solid copper wire through them and then flushing the drains with water.

Outdoor Fan

Because of poor maintenance, your air conditioner's outside fan may cease working or run slowly. The fan assists in transferring the heat your aircon absorb from the inside to the outside of your house. If it stops working, it may lead to overheating and, in the long term, compromise the compressor's performance. The outdoor fan should be cleaned and maintained regularly. You can quickly wipe down the fan and remove any accumulated dirt or dust.
