Maintaining your air conditioner properly can avoid or put off problems, but eventually wear and tear will take a toll. It is important to know when to service your AC, since small troubles can lead to big hassles if not taken care of. Here are some of the top signs it is time to call an AC technician:
Your air conditioning is on, but the air isn’t as cold as it should be, or it’s blowing hot air. This could be a sign of a bad compressor, dirty evaporator coils that need to be cleaned, or low freon levels.
If the airflow from your AC or vents is weak, this can be due to worn motors or a blockage or leak in your ductwork. Airflow problems caused by debris can also pollute indoor air and become a health hazard.
The presence of moisture can indicate a refrigerant leak or a damaged drain tube, which is designed to remove condensation when it’s working properly. Moisture can lead to rust, mold, and microbiological growth.
Air conditioners make some noise, but squealing, grinding, or grating sounds are not normal; they typically mean something inside the AC is broken or failing, such as a belt or motor. In some cases, parts may need to be lubricated.
If the air coming from your AC smells musty, there may be mold inside the unit or ductwork. A foul, pungent smell can mean the unit’s wire insulation has burned through, which can also be a fire hazard.

“Ryan was extremely professional and knowledgeable. He took the time to thoroughly explain everything in a clear, detailed way, which I genuinely appreciated. He was clean, respectful of our space, and very thorough in his work. You can tell he takes pride in what he does. He went above and beyond, and his kindness and professionalism did not go unnoticed. Highly recommend.”
“My technician Joseph was a solid and upstanding dude. He took his time doing an inspection of my old hvac system. He let me hover over him and helped educate me on the different components of the furnace and AC units. He didn’t tell me what I wanted to hear, but he told me what I needed to hear. Would trust him and his team to do my maintenance and future installs for my home.”
“Gabe was so efficient and explained everything so we could understand. He took his time to thoroughly look at all of our concerns and figure out some type of solution. I appreciate his taking the time with us!”
“My thermostat took a dive on me so I went to replace it. That’s where I met Breanna at Home Depot she advised me on the Ecobee one and normally I don’t use big companies because of cost is always higher since they have higher overhead. However, at $49 for a diagnostic they sent someone out and that’s when things got even better Lazaro was our technician. He was trustworthy and communicative and effective at explaining to me and my wife what he’s doing to our unit and why. In the end because of his demeanor and character I chose to get work done through his company. I got an ionizer placed and he patched a few areas where air was escaping. Cleaned condenser and added a second capacitor and cleaned the fan on inside of my house as well as checked the coils which were fine. In summary the company is trustworthy or at least my experience was good. At at a $49 diagnostic fee it was worth it to have someone come out and let me know where I’m at. Can’t say enough though about Lazaro he sold me on trusting next gen so if everyone is like him you’ll find value.”
