When it gets hot outside, we all want cool air inside. But your AC won't work well if no one checks on it. That's why we offer AC tune-ups. During a tune-up, we go through your system step by step. Every part is checked. We do this to help your air conditioner run better, use less power, and last longer.

Many people ask us what we do during a tune-up. So we're here to explain it all. If you're looking for a trusted air conditioning contractor Dos Palos, we're ready to help and make things simple. Let's walk through what we check.

An Air Conditioning Contractor Always Start With the Thermostat

The first thing we look at is your thermostat. That's the part on your wall where you set the temperature. We make sure it shows the right temperature. Then we check if it turns the AC on and off the right way.

If you have a smart thermostat, we look at the settings. Sometimes, small problems here make your house too hot or too cold. We do this first because it helps us know if the rest of the system is working right.

We Inspect and Clean the Air Filter

Next, we check the air filter. This filter helps clean the air that goes through your AC. But if it's dirty, it can block the air. Before we do anything else, we take a look at the filter.

We:

• See if it's dirty or full
• Change it if it needs to be
• Show you how to change it later

This is important. A clean filter means more cool air and lower bills. It also helps the system not work too hard.

We Check Electrical Connections and Controls

AC units have wires inside. These wires help all the parts talk to each other. If a wire is loose, the AC may stop working. That's why we check every wire during a tune-up. We look inside the unit and make sure all parts are safe.

Also, we check the power system. That includes parts like switches and relays. We turn the AC on and off a few times to see how it runs. Moreover, we do this so everything keeps working when it gets hot outside.

We Examine All Moving Parts

Inside your AC, some fans and motors move. These parts help the air go through your home. But if something is too dry or stuck, it won't move right. Therefore, we add oil to the moving parts and check how they work.

When fans or motors are off balance, they make loud noises or stop spinning. That can also make your AC break faster. As an HVAC contractor Dos Palos, we check all these things so the system runs smoothly. This helps your AC last longer.

We Clear the Drain Line

Your AC not only cools air—it also removes moisture. That water goes out through a drain line. But that line can get blocked. So we take time to clear the drain line. We also flush out dirt, mold, or anything that may clog it.

If the drain gets blocked, water can leak inside your home. That can lead to damage. As an HVAC contractor Dos Palos, we always check this to help stop problems before they start. Blocked drain lines can also cause bad smells and reduce indoor air quality. Regular checks also help keep the system clean and your home feeling fresh.

We Check and Clean the Coils

Your AC has two main coils—one inside and one outside. These coils also help move heat out of your house. But dirt and leaves can cover the coils. That makes it harder for the AC to do its job.

So, during a tune-up, we take time to:

• Look at the outdoor coil and clean off dust and leaves
• Check the indoor coil and clean it if needed
• Straighten bent metal fins to help air move better

Clean coils also mean your AC cools faster and saves energy. That's what a smart air conditioning contractor Dos Palos, always aims to do. Clean coils also help lower energy use during long, hot days. Moreover, this step supports steady cooling and helps reduce stress on other AC parts.

We Test the Whole System's Operation

After checking every part, we turn on the AC and test how it runs. This is how we know it's working right. We don't guess—we also check everything with real tools.

Here's what we do:

• Run the AC for a while
• Measure how much cooler the air gets
• Listen for strange noises
• Make sure the system turns off and on at the right times

This step shows us if anything still needs fixing. A well-trained air conditioning contractor Dos Palos, will always do this before finishing the job. This final testing helps catch small issues before they grow into larger problems. It also confirms the system is ready to handle daily use during warmer weather.
