G And A Mechanical A/C & Heating

G And A Mechanical A/C & Heating handles HVAC work across Houston and the Katy and West Houston zones. The outfit has served those spots for over thirty years under owners Mark and Allyson Hoag. Their focus stays on residential and commercial jobs that keep cooling and heating systems running through the local heat and humidity swings. Common needs include ductless setups plus ongoing maintenance that catches issues before they leave a house without air when temperatures spike. Homeowners count on them for straightforward repairs that restore comfort without dragging out over multiple visits.

Technicians like Gerardo show up even after seven thirty at night to fix units that quit cooling during peak heat. They check refrigerant levels, trace electrical draws, and replace faulty parts on the spot so the system holds temperature again by morning. Other calls involve full diagnostics on air handlers that catch up overnight but fail to stay steady, with crews explaining each step from coil inspection to drain line clearing. Annual heat checks cover burner tests, flue operation, and blower wheel cleaning on both gas and electric systems to cut utility costs and avoid breakdowns when cold fronts hit. Customers note the crews arrive ready with tools and finish the work the same day rather than scheduling follow ups.

Reviewers keep pointing to fast arrivals that beat expectations on evening calls, solid fixes that hold up through summer peaks, and clear talk on what broke and why the price fits the repair. Quality shows in proper diagnoses that avoid repeat visits while price stays reasonable on parts and labor. Communication stands out when technicians walk through every test and adjustment before leaving. Speed gets credit for same day resolutions on units that stopped during the worst heat.

“These guys were called by Choice Warranty to look at my aircon unit that stopped cooling during the hottest time of day. Catches up over night so is at temp in the morning (8/28/2023). The tech arrived in the morning topped up the refrigerant and wanted to leave. I said it was not fixed. It was not turning on as it used to - and like the other unit in the house - which I showed him. He looked around and said he could find nothing wrong. There was no paperwork to write my concerns on. Called back that evening when the unit was once again not working. Did not get a call back - so I called them after 10am. This guy said he would not send the same tech but he could not come out until next week. In this heat! I said they need to come at the time it's not working as clearly the tech did not believe me when I told him what was going on. Really, I am going to call a tech when there is no problem. See the pic attached - set to 73 - temp is now 78 and climbing! Would have been more professional of you to believe a customer instead of making excuses”

“Highly recommend! The team provided excellent service from start to finish. They arrived promptly, quickly diagnosed the issue, and had everything up and running in no time. Very professional, knowledgeable, and courteous. Great experience overall—I’ll definitely be using them again for any HVAC needs!”

“By far, hands down, the absolute best folks I've ever had servicing equipment on my home! I will absolutely recommend them to anyone and everyone. The technicians were wonderful, polite, professional, helpful, and informative and took the time to explain everything they were doing and why. If I could give more than 5 stars, I would! Again, best company/folks ever! 10/10! If I ever have any other issues, I will definitely be using G&A!”

“Gerardo did a fantastic job fixing my air conditioning unit. He arrived quickly, which was a shock as it was after 7:30 pm. He's a true professional as he was able to diagnose the problem quickly. He provided a fair price for the repair and I will definitely share his information with family and friends.”

“Our AC went out and Gerardo and Angel came out quickly to take a look at it. We needed a new outdoor unit and we got a fair price and they were honest and upfront about everything. They replaced it quickly and got our home cooling again. I would highly recommend to anyone for their AC needs.”
