“Hamstra provided a very competitive quote for the installation of a new Heating and AC system from which we selected them for our replacement. They came out this morning as scheduled and installed the system we contracted with them. The two installers, Brenden and Andreas could not have done a better job than the excellent installation they provided us. Their professionalism, attention to detail and the training they provided us to use the system was exceptional. We have always been extremely pleased with the service people Hamstra has provided. And now we have a quality system they installed that is providing our home with a very comfortable environment. Hamstra specifically made sure our system had all the appropriate features and correct size for our house and needs. We highly recommend Hamstra for anyone considering a replacement HVAC system and are confident that the employees they send out will do whatever they can to make your experience a pleasant and successful one.”

I know it wasn't part my planned annual winter tune- up but the old thermostat was becoming unreliable and I needed to replace it.

“I can't say enough about the gentlemen you sent to install my new HVAC SYSTEM. They both were very courteous and professional. Thank you HAMSTRA very sending the DREAM TEAM! There was another gentlemen also and he was just as courteous. My family has done business with HAMSTRA for 30 yrs. That will never change. Also being somewhat challenged with current technology, the guys helped be with the application so now I can run the AC wherever I'm at with WI-FI. The gentleman that came out definitely deserve a bonus in addition to there 5 STAR SERVICE. THANK YOU FOR INCREDIBLE SERVICE AND FOR ALL THE YEARS THAT YOU HAVE TAKEN CARE OF ME AND MY FAMILY. Also Kudos to Ryan for being patient with me. I only wish we had sales professionals as Excellent as Ryan. THANK YOU HAMSTRA!!!”

“We had (according to the office) one of the best technicians come out to repair our intermittent bug on our AC.
He was wonderful! in one minute he had diagnosed the problem and then fixed it! He then reviewed the unit and
made some adjustments to allow it to run more efficiently.
In our experience, all of the Hambra technicians we have had do a wonderful job, are very knowledgeable and
also very nice!
It is rare in this day and age to have a clean-cut, polite and knowledgeable repair person come to
your door. If you employ Hambra, you will not be disappointed!
Thank you Hambra!”

“We needed a whole new AC unit when ours failed during 100+ weather. Ryan, Heather, Andres , Elizabeth, Alex and Michael were fabulous, pleasant, quick to problem solve and kind. They were able to bring out a portable unit right away to keep our bedroom cool until they could do install about 5 days later. I didn’t have to wait endlessly to reach someone or to get answers. Granted, they had given us an estimate 9 months earlier so that probably helped expedite things but I feel confident they would have done everything possible to help us quickly even if that weren’t the case. Installation was completed yesterday and I feel human again.”

– Charlene O.

“Our central air conditioning stopped functioning a few days ago. I wasn't able to call Hamstra, with whom I have been doing business for nearly 30 years, until just before 5 p.m. that afternoon, but they were able to have a technician check the system the next morning. Zachary was able to locate and fix the problem very quickly and to check the entire system for correct operation at the same time. That was just outstanding service!!!! This is just what I have come to expect from Hamstra after many years of working with them on several residences with a variety of different HVAC installations.

Hamstra is the best!!”

– Benjamin S.

“I have had a great experience with Hamstra. Everyone I have come in contact with has been polite, friendly, professional , helpful and informative.

You were all great. You got my recommendation.”

“I have had Hamstra install and maintain my air conditioning system. The technicians are friendly, arrive on time, explain their and recommend ways to keep my system running top notch.

“The coil on the outside unit developed a large refrigerant leak and Hamstra did the initial diagnosis and final repair. The part took about a week to be delivered and during that time Hamstra made multiple service calls to keep my AC functioning until the new coil arrive. I only paid for one service fee but nothing for material. The unit broke down the latter part of July so Hamstra accommodating my household during the hottest time of year was a life saver and much appreciated. The actual repair was performed in a few hours and they had my house cooling in time to enjoy the weekend worry free. The technicians were very knowledgeable and professional. I will definitely be renewing my annual service contract with Hamstra.”

– Sandra P.

“The Tech, Hector, arrived on time, introduced himself and reviewed the reason for the call. He didn’t waste any time, except to answer my questions, and completed the work in less time than I was given. The whole experience was far better than the company I was using before . The price was less than other quotes. I will recommend Hamstra to my neighbors”

– Jake K.

“I was a little worried about the cooling ability of an 11 year old mini split in my art studio. I did not purchases it from Hamstra. I called Hamstra because they have been my HVAC company for the last 10 years. Mid july, hot and and humid, I had no idea they would be able to send a service man over in 2 days, Sunday morning. Turns out everything was fine, Jeff checked out the entire system and gave me good advice about the most efficient way to use the mini split for the erratic times that I spend in the studio in the summer. I had no problem paying the service call fee for peace of mind.”

– Ron K.

“I have been a regular customer and service plan member for about 10 years. HAMSTRA installed my current system and has done maintenance checkups twice a year. It is such a good feeling to know that I can trust them to do the work well and at a fair price. This week, in the middle of a 100-degree plus week, I had a capacitor go out and they sent a repairman the next day. He replaced the part under warranty and we were back to normal in less than 24 hours. Thanks, HAMSTRA, for having my back!!”

– Heidi H.

“I was given the 12-5 pm window and was called at 2 and a half hour notice. Caden was on time and very professional. He did our Summer check up and told me everything was working well.
I would highly recommend.”

– John H.

“My technician Houston came out and performed my annual bronze service. I have bitched for two years that my gaspack was undersized as it never shut off during the hot summer. Houston found an air leak on the outside duct work return air side and repaired it. Now I have a properly installed and operating system. I salute Houston for his time and professionalism on my project. I can't say the same about the rest of the staff at Hamstra. Two years is to long to get it right.”

– Mark P.

“Great service… the service person introduced himself, let me know what he was going to do, did not complain about my dog’s barking, in fact he worked quietly so as not to agitate the dog and when he made his recommendations he offered possible solutions.”

– Cristina L.

“I had some storm damage which included damage to the electrical line for my air conditioner. Hamstra called me back right away, set up an appointment and had the AC back up and running in a few hours. Great customer service from everyone!”

– Susan A.

“We appreciate the extra effort to come out to repair our non working AC. You were professional on the phone, quick to service and very accommodating. We were referred to y’all by Steve and Marcy Reed.

The person servicing our unit got it up and running but after he left we felt no cool air. Turns out he forgot to turn the disconnect back on on the outside unit. Thankfully, we figured it out on our own.

We did invest in a service plan and are cautiously optimistic it is worth the cost. Thanks again for coming out.”

– Skip W.

“Our AC was not cooling. Called Hamstra at 7 am and by noon the repair person arrived! So happy and appreciative at the fast response. The unit needed a new capacitor, which was replaced on the spot! Thank you Hamstra and repair person (I think your name is Caleb, if not, I apologize for not remembering your name). Than you! Thank you! Thank you!”

– Norma H.

“Daniel arrived for our routine Heat Pump maintenance yesterday and found a tiny coolant leak in a small copper line. Otherwise everything else checked out fine since the unit is only 8 moths old. The leak was fixed the following AM, a new part installed, and Daniel went over the entire process with me so I could understand the work he completed. The job was done in less time than he estimated. He is patient, professional and answered all my questions making certain I understood his work, the parts, and things to look out for. Daniel, and everyone I’ve ever dealt with at Hamstra are equally professional. We have used Hamstra since 2013 and would not think of choosing anyone else.”

– Ron K.

Salesman John, office installation coordinator Elizabeth, and installers Matt, Skyler, and David were all professional and skilled, and very attentive to the little things that make a difference.

Hamstra was recommended to us, and we would like to pass along assurance that it's a great company. They all went out of their way to make us happy. Highly recommend!”

– Constance W.

“Hamstra Heating & Cooling provides an exceptional service experience, and my recent interaction with their technician, Jake, exemplifies this commitment. Jake demonstrated politeness and consideration. This level of care and expertise made me feel informed and confident with every step of the process. Jake not only provided top-notch service but also went above and beyond from his polite and considerate demeanor to his detailed explanations and expert advice on the pros and cons of getting a new capacitor. Going above and beyond, Jake also replaced both air filters I provided. This level of dedication and attention to detail is what I feel sets Hamstra Heating & Cooling apart from other HVAC companies.”

“In the past 6 months I replaced (2) AC/Heating units with Hamstra. I dropped a pretty penny but my units were at 22 years old so I was due. All the folks we dealt with at Hamstra, starting with big John Sudback, Elizabeth in the office, the pre-install site team and then the actual install teams who do the work ALL were nothing but professional, positive and responsive. My sales person, John Sudbeck always was there for my endless questions and changes even when I would communicate with him on weekends. These days when often one cannot get a return phone call or you have to follow up on a continual basis…our experience with the Hamstra team was a breath of fresh air. Well run company — they get it! Thank you”

“HAMSTRA is a family of hard working, compassionate, honorable & honest people. What differentiates HAMSTRA from other companies are the people who work tirelessly so that our furnaces function in the winter months, and our air conditioners keep us cool during the long, hot summers. One of those hard workers is Brian. I have known Brian for years. He is a thoughtful, caring, & hard working young man who takes pride in his work. I run out of adjectives each time I write about him. He is a role model for hard working and honest workers.

Brian is a reflection of all the people who work at HAMSTRA. You are truly a family. Thank you for being a part of my family. I hope my words find their way to Brian. He deserves every accolade. I am so proud of him. I know HAMSTRA feels the same way. I may have run out of words, but never my gratitude for Brian & all THE HAMSTRA FAMILY.

Happy & Peaceful Holidays…
Please tell Lisa that her beautiful art cards have inspired so many of my art students. Lisa is also a shining star in the Hamstra Family.”

“Brian Adams visit today was to perform maintenance on newly installed air conditioner. He did a lot more by checking on a water leak after a rain and checked out and turned on home heater and that is now ready to used when needed.. He is knowledgeable and efficient and explained what he did. I am very satisfied with work he did today .”

“Zack was totally professional, efficient, friendly, and completed the job in less than an hour. He explained everything he was doing and answered all of my questions.

“We have used Hamstra for the last 10 years for all of our HVAC needs and never been disappointed. To take advantage of federal tax incentives, we decided to switch from a natural gas traditional furnace to an electric heat pump. We were also ready to part ways with the swamp cooler. Big John was aggressive about selling us a duct sealing service package, and I was reluctant, thinking it was a scam. Dust accumulation was a problem in our hose. Over the years I have learned to trust Big John and he said getting rid of the swamp cooler and sealing the duct work would make a difference. My wife and I are very pleased that we took his advice. The system runs much quieter, and much more efficiently we no longer have the dust issue in the house. Previous vents where we rarely felt heat or cool are are now sending air with much more strength to every corner of the house. Another detail is that we were also changing out the old 30 gallon tank water for a tankless on demand water heater using an independent plumbing service. Hamstra worked seamlessly with the plumbers schedule, so that both jobs could be completed in 3 days in a tiny utility closet. John’s typical motto is that Hamstra may not be the cheapest, but they will be the best. I cannot agree more. He answers the phone when I call.”

“I have always had excellent service from Hamstra, whether for my 6-month checkups or for advice on new or replacement equipment. I added a smart thermostat this fall and Jesus (Hamstra tech) did an excellent job at installing it. He also patiently gave me lots of hints on how to program it.”

“There were two Hamstra technicians here: one an experienced tech and the other was in training. We were very appreciative of the work both performed on our system. Clearly the Instructor tech was very knowledgeable and customer service oriented and made us aware of other programs that may serve our needs in the future. The Tech in training was also very customer service oriented and we clearly noticed that the workers hired by Hamstra have experience, a high work ethic and implement the company’s policy of a high level of customer service. We have always been impressed with Hamstra and over the years consistency in service and the effort to make the customer aware with preventive maintenance information appeals to us. We look forward to having Hamstra maintain our system as time goes on. Thank you Hamstra.”

“Everything was excellent with the technician. Only complaint I have is with the scheduling. Instead of either AM or PM service call. I had to waste and entire day waiting for the tech to call.”
