Accurate AC System Diagnostics You Can Trust
Why AC System Diagnostics Are Essential for Long-Term Comfort
Your cooling system is made up of many moving parts. Over time, wear and buildup can affect how your system runs. Professional AC system diagnostics help identify the root of the problem before it gets worse. At Sub-Thermal Solutions, we use advanced tools to test and evaluate your unit. Our trained technicians check every part of your system to make sure it’s running safely and efficiently.
Regular diagnostics can help prevent small problems from turning into major repairs. They also improve your unit’s performance and help reduce energy waste. Many customers in Northern Alabama rely on this service before peak summer heat hits. Keeping your AC in top condition means lower bills and better comfort for your family.
What’s Included in Our Detailed System Diagnostics Service
Our system diagnostics service is designed to find issues fast. We don’t just guess or replace random parts. We look for the cause of the problem and fix it the right way. During every diagnostic visit,
we:
Inspect Electrical Components and Wiring
Our team checks all wiring connections and electrical parts for damage or wear. We look for burnt contacts or loose connections that can cause performance issues. This step helps ensure your system runs safely and avoids unexpected shutdowns.
Measure Air Temperature and Pressure
We measure temperature and pressure to see if your system is cooling efficiently. These readings tell us how well your refrigerant and compressor are working. It helps detect hidden problems before they affect comfort levels.
Check Refrigerant Levels
Our technicians test refrigerant levels to make sure your system has the proper charge. Too little or too much refrigerant can harm the compressor and reduce efficiency. Adjusting it keeps your cooling cycle balanced and energy costs low.
Test the Thermostat for Accuracy
A faulty thermostat can cause uneven cooling or short cycling. We test its calibration to make sure it responds correctly to temperature changes. This helps maintain consistent comfort throughout your home.
Examine Filters, Coils, and Airflow
We check for clogged filters, dirty coils, and restricted airflow that can strain your unit. Clean components help air move freely and improve indoor air quality. This step also protects your system from overheating and early wear.
Identify Worn or Damaged Parts
Finally, we inspect all mechanical parts for signs of wear or damage. Catching these early prevents unexpected breakdowns during high-demand seasons. It’s one of the best ways to extend your system’s lifespan.
Once the AC unit diagnostics are complete, we walk you through what we found and give clear recommendations. You’ll always understand the next steps before any repair begins.
Clear Signs It’s Time for HVAC Diagnostics
It’s easy to overlook small performance changes until your AC stops working. Getting HVAC diagnostics at the first sign of trouble can save time and money.
Here are a few warning signs to look out for:
Uneven Cooling or Weak Airflow:
If certain rooms feel warmer than others, your system may have airflow issues. It could be a blocked duct or a failing blower motor. Diagnostics help find the cause and restore even cooling.
Strange Noises from the System:
Grinding, rattling, or buzzing sounds often point to worn-out parts or loose components. Ignoring them can lead to bigger problems later. A quick diagnostic test can stop the noise and prevent costly damage.
Warm Air Blowing from Vents:
Warm air is a common sign of refrigerant leaks or compressor issues. This problem reduces comfort and increases energy costs. Our technicians can pinpoint and fix the issue before your unit fails completely.
Short Cycling or Frequent Shutdowns:
If your system turns on and off too often, it may be overheating or misreading thermostat signals. Diagnostics identify the cause so your unit can run smoothly again.
Higher Than Normal Energy Bills:
A sudden rise in energy bills often means your system is working too hard. Regular diagnostics help restore performance and efficiency, saving money month after month.
One customer called us after noticing weak airflow in their living room. After a quick AC unit diagnostics test, we found a small leak in the duct system. Fixing it restored full airflow and lowered their energy bill immediately.

Each review reflects our dedication to transparency and care.
Jesse and his crew are professional and dependable. He replaced a split system for me. I had an issue with getting my job approved by the City of Huntsville. This issue had nothing to do with Jesse’s work, but to do with where the unit was previously placed. It wasn’t Jesse’s issue but he took it upon himself to intercede and resolve it to my benefit. I had several bids and Jesse’s was the most thorough. He even mentioned he would need to flush the lines to remove the old refrigerant to ensure no contamination with the new product. No other bid even mentioned this small but apparently important detail. This speaks to Jesse’s thoroughness. His dedication to his customers is top notch. Jesse cares about his customers and their families. In fact his office called me up several weeks ago and wanted to set up a time for Jesse to come out and be sure the unit had no issues before it cranked up for the summer. This is a FREE inspection and speaks to Jesse’s dedication to his customers and wanting to be certain they are taken care of. If you want a professional, dependable, fairly priced, and caring HVAC team look no further than Sub Thermal Solutions!

We appreciate Jesse and his work ethic. He arrived at the agreed upon time, was fair with his pricing and did great work. He installed a split unit in one building and repaired another
unit that was installed by a different company. We’re very impressed! Highly recommend

Our heat pump started acting up this morning. We contacted Sub-Thermal Solutions, based on reviews. Jesse did not disappoint and got us up and running by this afternoon, even going out of his way to pick up the part we needed from Gadsden. Can’t thank him enough. We are new to Ft Payne and would recommend his services.

We had a great experience with Sub-Thermal Solutions. First , I want to start by saying I called on Fri morning at 8:30 in hopes I could be scheduled for at least Mon to get our heat checked out. Luckily my house was close to the job they had and was able to get to me that morning. They were very thorough with their decision on how to get our heat back up and running. Within no time we had a game plan and some heat. I will definitely be using them if ever needed in future.

We purchased a home with no HVAC. We chose Sub Thermal to do the job because of their stellar ratings and the friendly, professional meeting we had with Ryan. He walked through everything with us and gave us a fair quote on a big job. The fantastic crew spent 2 full days here installing our new system. They were punctual, great at communication, knowledgeable and personable. I can’t say enough about what a great team they are and how well they work together to get the job done right. I definitely recommend Sub Thermal for all of your home’s needs.

Jesse at Sub-Thermal Solutions has worked on units at personal, rental and business properties for us. Very professional and HONEST!! He has worked in the freezing cold when my 85 year old mothers heat went out. On another occasion Jesse dropped what he was doing when the central unit in my VRBO went out ( in the scorching heat) while I had guest there for a week! That’s just two examples. I could list many more reasons for my 5 start review. I would give him 10 if Google had 10⭐!! I am a hairdresser and I recommend him to anyone that mentions needing a HVAC guy !!
