About

John G Maroulis runs an HVAC operation based in Houston, Texas, where the focus stays on air conditioning and heating systems for houses and small properties. The notes list dozens of small payments from local names and businesses, many under fifty dollars, which lines up with a pattern of handling frequent minor service calls rather than large installs. Houston heat and humidity put constant strain on equipment, so the work centers on keeping those units going through peak seasons without unnecessary extras. This setup fits the day to day reality of tradespeople who cover the city and surrounding areas for basic repairs and checks.

Common jobs include responding to no cool calls on rooftop units, clearing clogged drains that cause water damage, replacing worn capacitors during summer spikes, and testing thermostats that stop reading right. Houston homes often face frozen coils from poor airflow or high humidity buildup that leads to mold in ducts, and the crew deals with those by flushing lines and checking refrigerant levels on site. Small businesses listed in the records show similar patterns with quick fixes on packaged units rather than full replacements. The approach keeps things moving for repeat small accounts without dragging out the process.

Feedback shows repeated shortfalls on speed getting issues resolved, quality of the overall service, and how costs stack up across multiple visits. Communication tends to leave homeowners waiting on updates or clear explanations about what was found. These patterns hold across the set of reviews and pull the rating down. DIRT Score 1.73 from 13 reviews on Finds.

What Customers Say

Dr. WIillis basically refused care that I have had before because he wants me to start the paperwork all over!?!? So he can make all the fees all over again? He was rude and just walked out on his patient after I paid $175 just to see him.

Had an urgent visit for my mother (a long time patient of Dr. Willis) on a Thursday afternoon. The Dr had her do a blood draw and urinalysis to check for a UTI or other abnormalities and here it is the following Sunday and he still hasn’t read the results. The test were in her portal by 10:00 am on Friday morning. This isn’t the first time he hasn’t heard our concerns.

Dr Willis is a pill pusher. Took my mom in on a Thursday explaining how she wasn’t feeling good, hadn’t eaten or drank anything for two days. He said it was depression (my father passed in March) and increased her dosage for depression medication. He also said she just needed therapy and to see a preacher man. He ordered a CBC and UTI lab work. Results were back before noon on Friday and he never called to inform us of the results

It has been two years now that I’ve been seeing Dr. Willis and I still have no regrets on my choice of doctor when I moved here from Chicago. He is always so pleasant and walks in the room with a big smile on his face. He has been very thorough with my health and I always appreciate his feedback. Keep being a great doctor Dr. Willis 😁

I wish I could give a better review, but I had several incidents that caused me to make the decision to change doctors. I noticed the unfriendly atmosphere in his office and staff changes several months ago. The last time I saw Debbie, his nurse, she seemed irritable and spent little time with me.The next time I came in to see Dr. Willis, Debbie was not there and a new nurse was taking my blood pressure and vital signs. I was having trouble regulating my blood pressure with the new medications as my blood pressure medication had been recalled. I came in because I was worried about how high my blood pressure was reading on my home blood pressure monitor. The new nurse took my pressure and told me it was high. She said "I want you to sit here in the examining room for five minutes and I will retake it to see if perhaps you are stressed coming to see the doctor." She made me feel like I was imagining my high blood pressure! Five minutes later she comes back and takes my pressure again. It was still high. I was stunned when she said, "What did you do? Sit here and think about your blood pressure the whole time?" Dr. Willis came in to see me a few minutes later and seemed unconcerned about how high my blood pressure was reading, although he did change my medication. I also tried to see him one day when I was extremely ill from a urinary infection and I could not get in to see him. The appointment desk told me to go to the emergency room if I was that sick. My husband had to come home from work and take me to the closest ER to our house which is in Leander. I was shaking so bad that I could not hold anything in my hands. The ER doctor said I had "rigors" from the infection and they had to give me antibiotics by IV. I was told to follow up with my primary care doctor. I made an appointment to see Dr. Willis for the follow up and Dr. Willis appeared upset when I told him I went to the hospital in Leander instead of Georgetown. At this point, I felt that if you are more concerned about the hospital than my care it was time to change doctors! I loved Dr. Willis and Debbie, but things have drastically changed in this practice. On a last note, I called their office today to get my shot record and the person that answered the phone could barely speak English! My new doctor has yet to receive my records that we requested several months ago.
