HVAC Maintenance Checklist
You can list and perform three types of maintenance tasks when needed. Let’s have a look!
1. Routine or Monthly Checks for Your HVAC System
It is essential to conduct routine HVAC system maintenance. These are usually DIY jobs that are generally easy and may take a little of your time. Checking the following tasks to avoid any potential problems concerning your system:
- Look for debris, shrubs, leaves, or other blockages around your HVAC system’s outdoor unit. Keep the condenser fan exhaust as obstacle-free as possible.
- Make sure there are at least 2 feet of space around the indoor components of your HVAC system. These can be ducts, vents, or air inlets for portable or free-standing air conditioners. You want the indoor unit to get as much air as it possibly can without any hindrance.
- Check to see if your AC filters are clean. If not, they can be a load on your HVAC unit. Immediately clean or replace them.
Carry out an HVAC system inspection once a month to look out for refrigerant leaks. The refrigerant lines are typically made of copper and connect the outdoor unit to your AC’s indoor evaporator coil. The refrigerant absorbs the heat and provides cool air, and if your unit is low on refrigerant, it will run inefficiently, and your utility bills will skyrocket.
2. Seasonal HVAC Maintenance Checks
Seasonal heating and air conditioning maintenance ensures you enjoy the upcoming winter or summer season in peace!
Suppose your HVAC system is performing differently than it should. In that case, your desired temperature expectations may not be met, and your unit may also drain out more energy than it should. Here is a checklist to look into before the start of each season:
- Cleaning and replacing air filters.
- Clean evaporator coils and your AC’s condenser. Here’s a guide on AC coil cleaning.
- Check heating/cooling elements.
- Inspect fans and blades for proper operation.

3. Clean the Air Filters
After prolonged usage, the air filters can get clogged with dirt and dust. In addition, if you have pets at home, even more particles like fur and dander can block the filters. The result? Reduced efficiency and cooling from your air conditioner.
AC filter cleaning is essential to HVAC maintenance, as it ensures healthy indoor air quality. An unmaintained system can be a source of dust, mold, and bacteria.
Clean the filters every 2 weeks and replace them every 3-4 months, less if you have pets at home. What’s more, if you are using a smart AC controller, it will help you notify when to change your AC filter! When replacing filters, you should also consider the MERV rating. Filters between 7 and 13 ratings provide good filtration ability.
4. Clean the Area Around Your Indoor AC Unit
Keeping the area where your indoor unit is placed clean is highly important. This maintenance task can help your AC work better.
If there are storage boxes or any other clutter around it, it’s best to remove them. When you have stuff around the unit, there are more chances of dust settling there and making its way inside. This can affect your system’s efficiency. Plus, it reduces the air circulation in the area, which is also bad for your HVAC’s health. Clutter can also make it difficult to perform maintenance tasks.
5. Clear the Area Around Your Outdoor Unit
Make sure that there is at least two feet of clear area around your outdoor AC unit. The area needs to be clear of leaves, pollen, twigs, etc. Moreover, do not let your lawn mower discharge grass clippings onto the outer unit of your AC; otherwise, it will affect your system’s regular functioning. You can make a creative covering for your AC outdoor unit to prevent dirt from gathering around your HVAC unit. In case you have plants nearby by, keep them trimmed two feet from all sides for proper HVAC airflow.
6. Keep Your Outdoor Unit Clean
Dust and debris settle on filters and collect on important HVAC systems, such as the blower, condensing unit, and other moving parts. A thin layer of dust does not cause much harm, but debris can cause severe damage to your HVAC system.
Get your HVAC system checked by a professional who will carefully clean the accumulated foreign objects. This would help to prevent permanent corrosive damage to the internal systems of the condenser.
7. Check the Working of Your Thermostat
If your thermostat is not working, it needs to be inspected for proper functioning. It can malfunction due to a glitch or battery-related issues.
If your thermostat is not performing its job like it should, try resetting it. It can help solve connection or programming problems. Here’s how you can reset your thermostat to get rid of glitches.
Sometimes, your thermostat can’t read your home temperature accurately, which can affect your home climate. In this scenario, thermostat calibration can help. Your device can lose calibration due to dirt buildup or sudden loss of power in case of power outages.
8. Keep Track of Your Energy Usage
Monitoring your energy usage can help you discover any issues early on. You can use a smart thermostat to track your usage history. If you notice high electricity bills without any change in your HVAC usage, it can signal some problems with your unit. Call your heating/cooling company and schedule a service visit.
9. Keep Condensation Drain Clear
When your air conditioner runs at full tilt, it also extracts moisture from the air. That moisture then accumulates on the evaporator coil, from where it drips through the condensate drain. If this drain is blocked due to mold, dirt, or dust, the water can leak all over the indoor unit and even drip down your walls, creating stains.

10. Moving Parts – Lubricate Them!
Every HVAC system has moving parts that need to be lubricated to minimize friction. The lubrication process helps the components run smoothly and minimizes the resulting wear and tear. HVAC professionals remove the debris from moving parts and use the required lubricant to keep friction at a minimum. The lubrication process should be repeated often to save your system from any permanent damage.
11. Refrigerant Levels – Keep Them in Check!
Air conditioners need to have enough refrigerant to cool the air efficiently. If the refrigerant is not enough, the compressor will not run at total capacity, causing your air conditioner to work hard to achieve the desired temperature and, in most cases, not cool altogether.
This can be a potentially serious problem; you will be better off calling an HVAC professional. An HVAC refrigerant leak causes your air conditioner to operate at maximum power for a longer duration, causing significant damage. Signs that you have a refrigerant leak are:
- AC runs longer than usual
- Warm or room-temperature air is coming out of the vents
- No cooling is achieved
- High electricity bills with low AC usage
You cannot check the refrigerant on your own, as it is a poisonous gas; a professional will help you check refrigerant levels and recharge them if needed.
12. Monitor Carbon Monoxide Detectors
It is crucial to properly maintain your carbon monoxide detector to ensure it is functioning correctly and can alert you if dangerous levels of carbon monoxide are detected. The first step in maintaining your detector is to test it regularly. Also, be sure to replace the batteries every six months. Also, clean the detector by gently dusting it with a soft brush or cloth.
13. Inspect the Exhaust for Central HVAC Systems
In ducted systems, clogged exhaust outlets lead to a dangerous buildup of mold and algae, jeopardizing your safety and air quality. A technician needs to clear out the furnace exhaust from time to time so that the air flows smoothly out of the vents. Moreover, soot and debris can also accumulate and prevent the smooth outflow of gases, reducing the HVAC’s efficiency.
14. Inspect Fuel Lines
Fuel lines supply gas to your air conditioner’s furnace. Leaking fuel can be a fire hazard, and soot can clog fuel lines, affecting the system’s efficiency.
Regular HVAC maintenance will ensure that all traces of clogs are removed and leaking fuel lines are inspected before the issue gets out of hand.
15. Check the Electrical Connections
Regularly check the electrical connections and wires of your ducted HVAC system. If they are loose, they can become sources of electrical sparks and short circuits, which can be dangerous. Over time, they can then completely come off and prevent the proper functioning of your HVAC system. Get an HVAC technician to check the connection, as they can be a significant cause of concern.
16. Hiring an HVAC Technician
You can handle most of the standard and easy HVAC maintenance tasks, but let’s get to the facts – HVAC systems are complex machines. You might not be able to identify some deeper issues. These checks need to be done by an expert for the proper functioning of your system.
Ideally, you should get a professional HVAC inspection twice a year, preferably at the start of the heating and cooling seasons, to keep it running for an extended period.
Here is a breakdown of what professional servicing entails:
- Cleaning evaporator and condenser coils.
- Check for refrigerant leakage and if your unit requires a recharge.
- Screws tightening.
- Lubricating moving components
- Inspect the drain pan and drain line for blockage. If there is a clog, a professional will do a thorough cleaning.
- Checking blowing motor functionality.
