Reviews of local pros in Tulsa, Oklahoma

Outstanding service today! Nate was extremely thorough during his inspection of our electrical system and took the time to clearly answer every question we had. His professionalism, knowledge, and attention to detail really stood out. It’s rare to find someone who is both so skilled and so willing to make sure the customer fully understands everything. We truly appreciate the excellent service and would highly recommend him.

Simply said, FANTASTIC! We were scheduled for routine maintenance for Hvac and plumbing according to our service plan. Chris came out for Hvac and was great explaining everything. We purchased a "Scrubber" for medical reasons and actually for the cleanest environment our house has ever had and are so happy with the results! Michael was here for the Plumbing aspect and again was the BEST! We are extremely happy with the job and personel and recommend "QUALITY" for everyone! Professionals and great Personalities make us happy and comfortable with this company!

I was disappointed with this experience. This was my first time using this company, as I was giving them a try, and unfortunately it did not go well. The technician placed company stickers on my HVAC equipment at my rental property without my permission. Additionally, while they were there for routine cleaning and maintenance, my tenant was told the system is old and needs to be replaced and was presented with a very high replacement estimate. I did not request a replacement quote, and the unit is functioning properly.

Because of this experience, I will not be using them again. It’s frustrating to still see the stickers each time I access the attic or mechanical area. Please do not place marketing stickers on customers’ equipment without consent.

From the initial system check to reviewing options and completing the install, the team was communicative, professional and thorough. They kept us updated throughout the entire process and took extra time afterward to explain everything, setup the thermostat, help download the app, and make sure everything worked perfectly. I never felt pressured, overcharged, or left guessing. It was a terrific experience from start to finish. We will definitely use them again. Great team!

Quick and hard working also very experienced

Dale was caring and efficient. Very pleased with the service to help get my AC running again.

Had them out for a service call. Haven't had any more problems great price great customer service friendly staff I highly recommended them for any hear and air service you need

Dale and Serena are very knowledgeable my house was 96 degrees they came right out and fixed my unit. Dale will fix the unit instead of trying to upsale you, he is very honest and he has my business from here on out. Don’t pass this company up I can guarantee you will not find a more honest or knowledgeable hvac company

We tried out three different companies but Graham got our full time maintenance business. The crew was very professional and priced competitively. Totally recommend.

I had them come out and hook up my new ac unit. They were fast, knowledgeable, very nice and overall thrilled with the work they did. Great people, you should definitely let them have a go at your ac/heater.

Couldn't have asked for a better crew to come out and help me with my new AC unit. They did a fantastic job, were friendly and informative, and got my house cooling just in time for summer. Very smooth process and affordable pricing. Thank you Graham Heating & Air!

Dale Graham came out promptly and within minutes diagnosed problem with our mini split unit. Within minutes we had AC up and running. Reasonable charges, highly recommended. Thank you Dale!

I came home to no air conditioning and I called Dale Graham with Graham Mechanical, he was here within 30 minutes and had my air back up and running within 15 minutes. He is by far the best service I have ever had. I will use him again and recommend him to everyone. I will be using him for my yearly air service. Thank you Dale🫶

Dale and Isaac came out to diagnose why my evap froze up. They came out and wasted no time in finding the problem. They were very personable and professional. They diagnosed the issue quickly and thoroughly. Dale walked me through the problem, gave me multiple options to get it fixed, and Isaac kept in touch to insure the system worked probably after the repair. If you're looking for someone you can trust to do what's right by their customer, I couldn't recommend Graham mechanical enough.

Curtis Knight was very thorough, and really good at explaining our upstairs and downstairs units. We were given really bad service with another company in the broken arrow area. Thank you Curtis! 5 stars!

I have heat & air maintenance every year for 15 years. First year for ProThermal. They found a return air was covered by sheetrock which was corrected. Now my airflow is more consistent and the unit runs less thus saving more on utility bills. The employees do a great job. You can’t go wrong using them
