Rating: 5 out of 5 stars★ ★ ★ ★ ★☆ ☆ ☆ ☆ ☆I just have to rave for a minute about Aire Serv. Frank came to our home yesterday to look at our air-conditioning unit in which the fan had stopped working. My husband and I realized that the unit is old and we will need a new one soon, but Frank was extremely professional and polite. He showed us the part that needed to be replaced and went out of his way to explain our options. He replaced the part at a very reasonable price and had the a/c working again in less than 30 minutes. When it comes time to have our a/c unit replaced or repaired I will definitely call Aire Serv again.

Rating: 5 out of 5 stars★ ★ ★ ★ ★☆ ☆ ☆ ☆ ☆This is my second review for AireServ in Pasadena. Technicians have come and gone (unfortunately because all of them were great!) but service has remained consistent with each new technician. The detailed report they send out with pictures is extremely helpful and informative. I would also like to give a special acknowledgement to the Customer Service Representative Tina. She is extremely responsive, helpful and friendly- very conscientious, which you don't see much of these days. She really takes pride in her work (and it shows).

Rating: 5 out of 5 stars★ ★ ★ ★ ★☆ ☆ ☆ ☆ ☆We hired Aire Serv to work in collaboration with ServPro during lead remediation in our attic following the Eaton Fire. Aire Serv replaced our old and damaged air ducts and made some HVAC improvements in our new-to-us home. We were so impressed by their team's communication, flexibility, and professionalism throughout the process. Tina, Vanessa, and Adriana helped plan our work, communicating and collaborating with us with kindness and care. Isaac and Andrew installed our ducting and did a great job caring for our old, creaky home with thinly plastered ceilings. They had to patch a small area in our ceiling that cracked during the process, and did a beautiful job. Andy came out a couple times to troubleshoot wiring and connectivity, and got everything working without any issue. We will definitely call Aire Serv for future HVAC work.

Rating: 5 out of 5 stars★ ★ ★ ★ ★☆ ☆ ☆ ☆ ☆My tenant had the Gas Co. Come out to inspect her heater. It had a yellow flame indicating carbon monoxide. I called AireServ and they sent Lahcen out to diagnose the problem. The unit was kore than 25 years old and needed to be replaced. I did my due diligence to see if their estimate was fair and reasonable. It was. They replaced the unit today and my tenant is very happy. I called AireServ on Friday. Today is Monday and the job couldn’t have gone any better. From Xiochtl in the office to Lahcen in the field these guys were top notch. I know who I’m calling if any of my other units experience heating problem. AireServ!!! Sean Kennally Pasadena, CA

Aire Serv starts by identifying the issue with a thorough diagnostic, then shares a flat-rate price before proceeding. You’ll receive written details on parts, labor, and timing to ensure complete clarity. During every job, your local service professional walks you through the diagnosis and provides a side-by-side breakdown of costs for a quick fix compared to a full repair or upgrade.

An Aire Serv service professional will confirm your slot, and you’ll receive updates according to your area and current call volume. Evening, weekend, and holiday availability may differ depending on your area. In Duarte, your Aire Serv service professional will explain any extra fees upfront.

Our brand-agnostic approach and warranty knowledge mean older systems get careful attention, while newer units are serviced using proper OEM procedures. Routine care is the secret to a furnace that works reliably year after year. Our furnace tune-ups and cleaning services are designed for your system’s brand and age, improving efficiency, catching issues before they grow, and adding years to your equipment. Heating problems don’t wait—and neither do we. No matter the age of your system, we offer emergency HVAC service in Duarte with a team ready to diagnose and fix the issue quickly. If repairing your furnace isn’t the most budget-friendly solution, we’ll help you select a replacement that fits perfectly and saves energy.
-
Should your furnace turn on and off too often (short cycling) or certain areas never reach the set temperature, it’s likely a sign of a performance issue. Faulty sensors, dirty filters, or blower problems are common culprits, often fixed through a furnace tune-up or repair. If your carbon monoxide alarm sounds while the furnace is active—or you spot soot by registers, rust on the flue, or heavy window condensation—treat it as a safety emergency. Turn off the system, allow fresh air in, and call for emergency HVAC service immediately. In the event of any of these indicators, a professional tune-up and furnace cleaning can help restore efficiency, stabilize temperatures, and prevent surprise shutdowns. If your system is more than 15 years old, requires frequent repairs, or the repair cost is nearing half the price of a new unit, it might make sense to consider a replacement. A professional evaluation can help you weigh efficiency improvements and overall costs for furnace replacement in Duarte.
