Another Awesome Service Technician

On Wed. February 15, 2017 after experiencing intermittent burner shutdown on my hot water heater for a few days, I placed a call to AC Engineers and spoke with Paul. I explained the problem & he promptly set my service call for Thursday, Feb. 16 between 8 & 10 am. On Thursday, Feb 16, @ 8:10 am, I received a call from Laurie of AC Engineers informing me the technician was on his way to my house. At 8:30 am, Doug K. appeared at my door. I led him to the hot water heater while explaining the problem I was experiencing. He quickly assessed the problem, telephoned the office to see if the part (burner door gasket) was available. He stated he had to drive to the office to get the part and would return shortly. After thoroughly cleaning the burner & compartment he installed the new door gasket and we were up & running with hot water @ 10 am. Doug K is an affable, knowledgeable, skilled and efficient technician. Thank you AC Engineers Team for another "JOB WELL DONE"!

Great service especially when your tech tells you he's sorry he couldn't find anything wrong!

Doug was amazing! So friendly and thorough! Was very comfortable having him in my home.

Awesome, quick service, reasonable price

Doug K provided excellent, very professional service and answered all my questions. I would recommend him and your company to anyone who asks.


a wonderful dedicated man, and through beyond belief, I am so happy and satisfied with knowledge in solving my problem .

great service

Excellent service!

Doug showed up on time, promptly got to work, took the time to explain what happened to our system and even showed me some features I wasn't aware of. Great employee!


We appreciate the great work provided by Air Conditioning Engineers and Doug is particular. Always professional, arrives as scheduled and completes the job at hand.

Great service

Made my appointment on Wed. for Thur morning. Tech called to let us know he would be here in 30 min and was here in 25. Very professional and friendly.. Got the unit charged and working in 30 min.

Always a good experience!

Twice a year I have someone from ACE checking the furnace and a/c. Each time, it's like seeing a friend again. Monday, it was Doug who was here and I hadn't seen him in quite a while. All the technicians are friendly and helpful. Doug is one of the best!

Quick Service

Doug knows his stuff, and if had a problem with my heating and cooling, I would request his service. High marks for Doug!

Doug is the absolute best.

Friendly Service

Doug K was very friendly, greeted me with a smile and worked with me to confirm all my questions, concerns, and worries. He was very informative, professional and courteous, and made sure that I was all up to date and satisfied with the order before he departed.

Friendly, efficient, effective

Doug was very professional, friendly, insightful and diligent. Could not ask for a better service experience.

Doug is knowledgeable, polite, trustworthy and our "main man" for service on our furnace/ac systems.

Very satisfied with tha service

very thorough

great service

assisted with very nice receptionist , very professional technician, repair has been done quickly I would recommend it to anyone

good service

if service is this good again I be a good customer

Great job.

Doug and his team did a wonderful job. They arrived when promised,worked quickly, and cleaned up after they were finished. Doug was very friendly and knowledgeable, he answered my questions and showed me some new features that I didn't have on my old water heater. However, I was shocked when I was told the cost of the heater plus installation. It wasn't the company, it was because of government regulations. If you need a water heater, get it now before the price goes up!

Great visit - always enjoy seeing Doug.

Thumbs up !

Very pleased with the service. Technician discovered that expensive defective part was covered by warranty. This saved me hundreds of $$$

Been doing business with AC Engineers for years...I highly recommend

Doug K, yearly a/c clean and check....

I was so relieved to see AC Engineers installed hot water heaters. I know I can trust what they tell me and the work they do will be done right. I trust my furnace, air conditioner and now hot water heater to them. Electrical is next. Thanx for always being there.
