Houston, TX Heating, Cooling & Refrigeration

Gregg showed up as expected despite his van breaking down the evening before. He was both knowledgeable and patient as he took his time to work diagnose a handful of issues in our geothermal system. Always a pleasure to meet someone so willing to spend their time and share their experience to get the job done.

This is the second unit Greg has put in for us and both times we have received top notch customer service.

I have used this company several times now and have been fully satisfied. Greg has years of experience behind him and is extremely knowledgeable about all things related to AC. Great service at a fair price. I will continue ur to use this company.

Greg is wonderful, dependable, reliable, and an all around great guy.

Very knowledgeable and by the book with no nonsense adherence to codes and standards. Job done right

Great job. I write this after 7 months with the new system. I achieved a very important status with it which is I forgotten that is there. I works in the background quietly, efficiently (saving approx. 600 kw. monthly) regardless of heat or cold.The whole job was quick and very clean. Highly recommended.

Ever since Gregg installed our Trane unit about 3 1/2 years ago, we've been very satisfied with the installation and service. Highly recommend him for any HVAC work.

I had a very positive experience with A1 Tops Services. Greg, the owner, was extremely knowledgeable and helpful on recommending the appropriate size and power HVAC unit for my home. He stayed on site with his crew for the whole job. They did a quality job St competitive pricing. I’d use them again,

Gregg, the owner, saw that some wires ‘fried’. They got too hot causing the compressor to quit working. Gregg fixed the wiring. Then, he noticed the capacitors were not working. He replaced those and reviewed all the wiring. Also, he checked the Freon levels. Gregg is most thorough.

Gregg is a very friendly, knowledgeable and experienced A/C expert. He was not only timely but quickly diagnosed the problem, installed new part, cleaned, serviced and tested unit I highly recommend Gregg and his company, A-1 Tops Services for your A/C and Heating needs

Greg did an excellent job and within the time he indicated the job would be done.

works perfectly

A-1 did a great job. Gregg took his time and checked everything from top to bottom. He is very reasonable on his rates. I highly recommend him.

He is here when he said he would, took care of my issues efficiently.

My A/C went out on Wednesday (95° inside my home) and Alex was there the very next day. He was courteous, professional and offered some great advice for maintenance of my unit. We are now comfortable again... thank you A-1! You saved us from another unbearably scorching night.
