Sergio Lopez A/C & Heating

Sergio Lopez A/C & Heating works out of Edinburg, Texas, and focuses on HVAC work across the Rio Grande Valley. The crew takes on heating installations along with repairs and maintenance for homes and businesses that face the region's extreme heat and sudden winter cold fronts. They handle both new construction setups and fixes on existing systems, showing up for calls on units that quit during peak use. Homeowners in the area reach out for straightforward service on compressors, heat pumps, and full heating jobs without extra layers of process.

Sergio and his team show up for compressor failures on older AC units, where they walk through repair versus replacement options with clear pricing details. They also handle heater repairs on brand new builds, replacing broken parts the next day after an initial visit, and perform full AC and heating installs in new homes that hold up through years of minimal use until a cold spell hits. Maintenance calls cover heat pump inspections and tune-ups, with attention paid to every component during the visit. The work covers all major brands and includes ductwork checks plus thermostat adjustments as part of standard service runs.

Customers highlight fast arrivals on repair calls, honest breakdowns of costs for different fixes, and solid results that keep systems running through Texas weather swings. Quality shows in installations that need little attention years later, while price feedback often notes fair quotes without pressure. Communication stands out when Sergio stays on the line to explain issues and next steps. A lower overall mark comes from a few cases with parts delays or scheduling gaps.

“Cannot say enough good things about Sergio and his team. They worked quickly, provided excellent service, and a great price. The compressor in my ac died and Sergio took the time to answer all of my questions and offered me comprehensive pricing for a variety of solutions ranging from repairing the unit (7 y/o) to replacing it. The employees who came to my home to complete the work were professional and courteous. From the time of the service call to the installation of a new system, less than 48 hours passed. Of note, I have a child who is medically complex so it was vital to have someone who could complete the work quickly. Having a cool home is critical to maintaining appropriate care for her and Sergio and his team rose to the challenge. 10/10 definitely recommend.”

“I just wanted to thank Sergio for the great service he provided me. Sergio's company installed the AC and Heating to my new home 4 1/2 years ago. Other than starting the heating once to make sure it worked and two days a year ago, it has not been needed here in Yuma. This year has been very cold and we finally started to use the furnace. It started having issues starting and then starting but not heating. I had spoken to Sergio when the unit was first installed and he had been very helpful on giving me some guidance on the proper use of the AC since I had never lived in this hot of a climate. I contacted Sergio regarding the issue with the furnace and he came right out and looked it over. He found that there had been a mistake made when it was installed, this is when his exceptional character and great customer service showed. It had been 4 1/2 years since it was installed by his employees, he did not have to admit to a mistake being made or just made excuses. Sergio did neither, he ordered the part and came back and took care of it. There were a couple to adjustments that were necessary to get the heat working perfect and Sergio came out and did them without excuses or complaints. I wanted to commend Sergio and his business for his exceptional service and honesty which quite frankly are hard to find these days. Sergio will have my business as long is he is around. Thank you for your great service.”

“We called Lopez A/C yesterday to ask for an inspection/maintenance tuneup of our heat pump. We just had Sergio come and do an inspection and standard maintenance on our heat pump. What a lovely person he is! His attention to detail was top notch as was the complete service he performed for us. He took time to explain to us what he saw with our unit and what he would recommend for standard maintenance for the future. Lopez A/C was recommended to us by friends, and we could not be happier with the service we received. I would highly recommend Sergio and Lopez A/C!”
