As summer approaches, ensuring your HVAC system is in top-notch condition becomes paramount. If the heating system or air conditioning unit breaks down, you could go without it for a few days while you wait for a fix or a few weeks if it needs to be changed. 

You can prevent this by doing an HVAC summer tune-up to improve your system’s performance, extend its life, reduce energy bills, and get more comfort. 

In this guide, we’ll walk you through 17 crucial steps before the season hits full swing, from performing DIY checks and repairs, and hiring experts or technicians to considering upgrades to prepare your HVAC system for a stress-free summer of cooling.

17 THINGS YOU MUST DO BEFORE THE SEASON

1. CLEAN OR REPLACE AIR FILTERS 

Before summer arrives, it is a good idea to check the filter to ensure that your air conditioner operates at its best. Air filters are crucial in maintaining indoor air quality and system efficiency. Clean or replace the air filters while carrying out your HVAC summer tune-up. 

Filters remove dust, hair, and other airborne particles to stop the spread of dangerous pollutants throughout the home. As a result, when they become clogged, airflow is restricted, which makes the system work harder and uses more energy. 

Now, Depending on your system type, you may need to change the filter once a month, once every six months, or once a year.

For the majority of the systems, filters with a MERV rating between seven and thirteen provide an excellent compromise between maximum airflow and filtration efficiency. When in doubt, follow the manufacturer’s recommendation.

2. INSPECT ALL UNIT PANELS

In carrying out your HVAC summer tune-up, carefully inspect all the unit panels. Over time, these panels might get loose due to weather conditions or regular use. Secure any open panels to prevent vibrations and potential damage to the internal components.

3. CHECKING REFRIGERANT LINES AND AIRFLOW

The evaporator coil, which is close to the air handler, is connected to the outdoor condensing unit by copper coolant lines. Foam insulation is applied over and around these lines to protect them.

Checking to see if there are areas where this insulation is damaged or missing and replacing it with insulation sleeves or wrapping the lines with foam tape is one of the crucial HVAC summer tune-ups.

Also, Examine the refrigerant lines for any signs of leakage. Low refrigerant levels can impact cooling efficiency. You should ensure that no obstructions are blocking the airflow around the unit. Proper airflow is crucial for efficient operation.

4. CLEAR AWAY DEBRIS

Winter may have left dirt, twigs, leaves, and debris in your unit’s exterior condenser or compressor. To remove these leaves and other debris stuck in the unit, use a hand vacuum, a strong degreaser, and a considerable amount of elbow grease. 

To access the interior, you typically also need a screwdriver or tool. This promotes proper airflow, preventing the system from working harder than necessary.

During this time, you should also trim any vegetation within two feet of your unit. Although shrubs and other vegetation may not directly restrict airflow around your unit, they can nevertheless have an impact.

Outdoor units are prone to collecting debris such as leaves, twigs, and dirt. Clear away any debris around and within the unit. This promotes proper airflow, preventing the system from working harder than necessary.

5. PERFORM VISUAL INSPECTION OF THE HVAC SYSTEM

As you go on and about your HVAC summer tune-up, Inspect the system when changing the filter to uncover potential problems. Check out the thermostat, inside and outside the unit, registers, and returns. 

In addition to that:

• The thermostat’s battery condition should be checked.
• Confirm that the condensate system is draining properly 
• Make sure the cabinet door and filter access are shut tightly.
• Check that the flue system is completely intact and attached firmly.
• Check that all returns and registers are accessible and unblocked.
• Examine each register for mold traces.
• Ensure that the outdoor appliance is level. If necessary, use rot-proof shims to level it.

6. REPAIR OR REPLACE PIPE INSULATION

Inspect the insulation around the refrigerant pipes. Damaged or deteriorating insulation can lead to energy loss and reduced cooling efficiency. Replace or repair any damaged insulation to ensure optimal performance.

7. PREPARE TO MAXIMIZE COOLING POWER

Overuse is a frequent cause of air conditioner failure. High electricity expenses are another consequence of running your AC more frequently than necessary.

Fortunately, you can do several things to reduce your cooling requirements while performing an HVAC summer tune-up.

Consider shading the outdoor unit with plants or a shade cloth. This can help the unit work more effectively and efficiently by reducing its exposure to direct sunlight. 

Additionally, seal any gaps or cracks in your home’s windows and doors to prevent cool air from escaping; run the ceiling fan to create a wind-chill effect; and only make use of the oven, dishwasher, and clothes dryer during the cool hours of the day.

8. CHECK THE DRAINAGE LINE

When carrying out a DIY HVAC summer tune-up, examine the drainage line to ensure it’s clear of any obstructions. A clogged drainage line can lead to water leaks and potential damage. Clear the line using water and bleach to prevent mold growth.

The pipe occasionally empties into the ground near your other unit, but typically, it ends in your basement at a utility sink or floor drain. Once you’ve found the drain line’s termination, connect a vacuum hose to the gap. 

Last but not least, run the vacuum for a few minutes to remove any possible mold or algae growth.

9. KEEP THE CARBON MONOXIDE DETECTOR ACTIVE

A carbon monoxide detector is a crucial safety equipment for homes with combustion-based heating systems like natural gas or fuel oil. 

The alert could save your life in the event of an exhaust leak, poor ventilation, excessive gas flow, or other problems.

The typical working life of these gadgets is seven years. Regularly check the carbon monoxide detector to ensure it is in good working order, and replace it if necessary when performing your HVAC summer tune-up.

10. CLEAN THE OUTDOOR CONDENSING UNIT

Split-system air conditioner condensing units are placed on a concrete slab outside your home. To remove hot air from your house, a fan, and fins that serve as heat sinks are within this big metal box. 

Due to its open location, the condensing unit is exposed to the elements. To ensure an effective heat exchange process, you should clean out any dirt and debris that has accumulated over time as part of your HVAC summer tune-up.

11. CLEAN THE EVAPORATOR     COIL

The evaporator coil’s efficiency is affected by the collection of dust and dirt. Find the evaporator coil door on your unit, then open it while removing any necessary screws or bolts. 

To eliminate dirt buildup, gently clean the coil with a soft brush or compressed air. Next, spray the coil with a commercial coil cleaner—a clean evaporator coil guarantees effective heat exchange and improved cooling.

12. REGULATE YOUR HOME TEMPERATURE

Running your HVAC system at reasonable temperatures and minimizing its use while you are away from home or sleeping are all parts of performing an HVAC summer tune-up. 

If you want to automatically control the temperature throughout the day, consider installing a programmable thermostat.

13. REPAIR OR REPLACE PIPE INSULATION

Inspect the insulation around the refrigerant pipes. Damaged or deteriorating insulation can lead to energy loss and reduced cooling efficiency.

Replacing or repairing any damaged insulation are HVAC summer tune-up measures to ensure optimal performance.

14. CHECKING PRESSURE LEVEL

Checking pressure levels against manufacturer standards is a crucial part of HVAC summer tune-up. Ideally, the same baseline pressures measured at the time of installation should be maintained. 

Several pressures, including gas, refrigerant, exhaust, static, and air, may need to be checked during your HVAC summer tune-up and adjustments made where necessary.

15. SCHEDULING PROFESSIONAL HVAC MAINTENANCE

While DIY HVAC summer tune-up is valuable, scheduling a professional HVAC maintenance service is equally important. Professionals have the expertise to conduct a thorough inspection, identify potential issues, and fine-tune your system for optimal performance.
