The Basics of HVAC Unit Maintenance For Newbies & Beginners

Heating and cooling systems require routine maintenance to keep them running efficiently. It is important to check the parts and inspect them thoroughly before making any major repairs. You should perform seasonal filter changes as well to reduce strain on the system and save on energy costs. An annual inspection of the system is also vital. This can prevent any major damage and extend its useful life.

Maintenance of HVAC system

When you have a heating and cooling system in your home, it is important to maintain it on a regular basis. Proper maintenance can ensure that the system functions properly and lasts a long time. The best way to maintain your system is to hire a qualified technician and schedule routine maintenance. You can find out if the technician you hire is reputable by looking at independent online and social media reviews.

Regular maintenance can reduce the cost of cooling by up to 20 percent. Additionally, it will allow you to have more control over your heating and cooling system. A qualified heating and cooling technician can perform a regular maintenance check on your system and recommend a carbon monoxide detector to keep you and your family safe. Also, well-maintained heating and cooling systems use less fuel.



HVAC inspectors can check the operation of your heating and cooling system to make sure everything is working correctly. They will check the operation of your control systems and blower components for proper airflow. They will also check the safety and pressure of your gas lines. Heating and cooling system inspections can also check the efficiency of humidifiers ( and radiant floor heating.

It is important to have a professional look over your heating and cooling system at least once a year. These inspections will identify potential trouble spots and prevent your heating and cooling system from running too poorly. Ideally, you should schedule an inspection of your heating and cooling system every spring and fall, which will ensure your home comfort throughout the entire year.

In addition to saving money on energy costs, regular inspections of your heating and cooling unit will improve the life of your system. It will reduce the likelihood of unexpected emergency repair bills and no heat when you need it most. You’ll also be able to enjoy more comfort with less money.



Getting your heating and cooling system cleaned regularly can improve the quality of the air you breathe and extend the lifespan of the components. This can result in reduced energy costs and increased efficiency. It may also reduce energy waste. However, you should not assume that cleaning the ductwork alone will improve your home’s indoor air quality.

Dirty HVAC components are not only inefficient but also potentially dangerous. Dust, pet hair, pollen, and mold can all gather on the components and cause allergies and asthma complications. These contaminants may also cause other health problems, such as dry eyes and itchy throats. In addition, dirty HVAC systems can be harder to clean because they circulate more dust throughout the home.

Dust will settle on surfaces and remain on the HVAC system for long periods of time. One solution to this problem is to install a whole-house air cleaner in your home. To get the best results, it is important to hire a certified expert to clean your HVAC system. These professionals have extensive knowledge and are trained to handle any situation that arises.

In addition to cleaning ductwork, they also perform additional maintenance steps. These include cleaning the evaporator coil and drain channel, and removing any buildup of debris. A well-kept HVAC system is an efficient way to save on energy and money. By keeping your unit clean, it will last longer and require fewer repairs. Clean vents are also an essential part of HVAC maintenance. If your vents are dirty, your system will struggle to produce cool air and use more energy.


Lubrication is an essential part of heating and cooling system upkeep. It ensures smooth operation of moving parts in the system, protects them from wear and tear, and reduces friction. Properly lubricated system parts also reduce the likelihood of unexpected repairs and help to conserve energy.

Without proper lubrication, airflow will become poor and your system will work longer and harder. Additionally, the lack of lubrication will cause friction and wear down the motors. This will lead to belt and fan blades breaking down, and motors will lose efficiency. Often, these parts will start to emit loud clicking noises as well, which is a warning sign that something is wrong.

While many people do not notice HVAC system lubrication, it is crucial for upkeep. During hot summer months, lubrication is particularly important. The risk of run out is higher, and more frequent checks are necessary. To make HVAC system upkeep easier, install an automatic lubrication dispenser.

Air filter replacement

Performing air filter replacement is a crucial part of heating and cooling system maintenance. If you want to keep your heating and cooling system running properly, you should do this at least once a year. When replacing the air filter, it is important to use the correct size for your heating system.

To get the right size, measure the air filter by measuring its dimensions. If the filter is too big or too small, it will let dirt and debris pass through, which can damage the HVAC system. A professional HVAC contractor will be able to give you recommendations on the correct filter size. A clogged air filter can lead to a range of HVAC system maintenance problems.

This includes insufficient air flow, a damaged blower and dust in the ductwork. Regularly replacing the air filter will keep your system running smoothly and save you money in the long run. A dirty air filter will reduce the flow of air and will damage your heating and cooling system.

Dirty filters also reduce the efficiency of your system, requiring longer running times, but you can learn more about cleaning them by clicking here. If you notice a noticeable reduction in efficiency, it’s time to replace your air filter. It’s best to replace the filter every three to six months. Changing the air filter is an essential part of heating and cooling system maintenance.

The air filter is the most important component of your HVAC system and needs to be cleaned regularly. If you have a pet or have a dirty air filter, it’s essential to vacuum your floors regularly. Vacuuming the filter is an easy way to remove most of the dust and loose debris that may accumulate inside the filter.
