Very happy with the A/C.

Mr. and Mrs. Eldridge

We purchased the Mitsubishi mini-ductless system for our newly constructed four season room. I am very pleased with the how professional and courteous Suretemp was during the entire purchase and Installation process. Their price was competitive and lowest as I received other bids from local heating companies for the same Mitsubishi unit. The salesman (Ed Miller Jr.) was very informative and patient as it was a 9 month cycle from the time I first contacted suretemp and I committed to the installation. I would definitely recommend Suretemp as a competent, reasonable price heating contractor to other people.

Bill Vaughn

I have done business with Sure Temp for almost 30 years. They are consistently reliable and offer high quality products at a very fair price. I won't do business with anyone else.

Tom Miller (out of the Binghamton, NY office was exceptional. He shoveled waist-deep snow down a very long driveway, just to provide a proposal! All of the work and the products were excellent. Rick Duggan - 300 Canyon Oaks Dr., Wimberley, TX 78676 - installed at 88 Hanson Rd., Depopsit, NY 13754

Rick Duggan

Tom explained my options very clearly and got a quote out to me right away which included 3 optional units. John and Scott were a pleasure to work with and were very contiencious throughout the project. At the end, John reexamined the entire scope of the work they had done and made sure he was comfortable with the workmanship as well as the performance of the units and that I was 100% satisfied before the project was finalized. I would not hesitate to recommend Sure Temp based on my exceptional experience with Tom, John and Scott.

Ron Sherwood

First thing said from the installation crew , after introductions, "Should I take my shoes off?" That never happens. The crew seemed as excited about the unit as I was and kept pointing out features and power ratings as they opened and inspected the packages. It was a long day but worth it!

Geoff Powers

Overall the experience was good. I felt that the progression of the work being done went slowly. I conveyed this to Ed Miller Jr. I also had Paul Alteri from Finger lakes Construction call Ed as well about this issue as I had a deadline.

Michael Moore

Excellent service! We are extremely satisfied.

Mike and Theresa Lucas

I was pleased with the unit I purchased and the quality work done during the installation. Both Carl and Scott were willing to answer any questions I had and to do whatever I asked - a job well-done.

Mr. and Mrs. Burch

On 10/7/15 service was performed on my furnace. Ben did an excellent job!!! He informed me of your annual service program. I called on the same date for the paperwork to participate. Still have not received it. Can this be sent to me?

Steve Sparling

The salesrep, Tom, worked with us to quote the product and installation that was right for our home. The other guys kinda quoted what they wanted to give us. The finished installation looked like a project that was installed by individuals that took pride in their work.

Steve Herrick

your crew was on top of the situation. Here on time and I believe they worked through lunch to get the job done. Tom was helpful and replied promptly whenever I had questions.

Rick Krno

We had had AC trouble over the July 4 weekend and called at 8 AM to request a repair person first thing on the Tuesday after (July 5). Ben and a new employee came, found a faulty valve, re-gassed the unit, and thought it was fixed. It was, for a day. When we called first thing on Thursday morning, we couldn't get a repairperson until mid-afternoon, and by the time they figured out what was wrong, it was 4 PM and too late to get a new unit on Friday. So we had to wait another weekend to get the work completed on the following Monday (July 11). That's a lot of waiting when we are good, repeat customers,when it wasn't our fault that the problem wasn't fully diagnosed the first time the repairmen came out--and when we are allergy-sufferers! We were distressed. We should be charged for the two service calls.

Mr. and Mrs. Burch

Sure Temp - YOU ARE THE BEST OF THE BEST. Everything, from the first time I phoned asking about air conditioning for my home, was done professionally and in a very respectful manner to me, and my two children - son in Buffalo, and daughter in Allentown, Pa, who were immediately kept informed of all options available to me, via e-mail (I am new to e mail) and we were able to make a decision immediately. Your service and everything else was EXCEPTIONAL - and with the past week of 90 plus temperature, I sure appreciated the 69 in the house (plus the cats). Why did I wait 42 years??? I told my daughter if I ever move, the place will have to have air conditioning. Thank you, Vilma Byrne, 607-729-0250 . I recommend Sure Temp l00%

Vilma Byrne

Respectful and courteous staff were efficient and cheerful to have in our home.

Jan Fiore

From my initial inquiry call to SURE-TEMP to Tom coming to our home, to the completion of installation with Jon & Nick and follow up with Tom on selecting our maintenance contract I have to say we felt comfortable that our needs were being met. The total experience has exceeded all aspects of professionalism, trust & confidence involved in our investment to improve our quality of life. I would whole heartedly recommend SURE-TEMP's Team to friends & family.

Mr. and Mrs. Randesi

Mr. and Mrs. O'donnell

Norm worked very diligently to correct our issues. It was a very hot day and no shade to work in. He kept at the work until we had cooling again. Norm has a great attitude and a pleasure to work with.

Thomas Mayo (TST Boces)

The installers did a great job! Tom Miller was a valued resource throughout the project. I recommend the use of "booties" on the service techs feet. It would make the job neater and save on our floors.

Oliver Blaise

Unfortunately I was out of town for the installation and was not able to get any instructions for how to maintain boiler if necessary. For example, does the water automatically fill itself with water as needed.

Leo O’connor

I had a positive experience with Sure-Temp. The salesman and the technicians were all friendly and helpful.

John and Caroline Labusohr

We have had you check our old furnace every other year for about 15 years. It was always left In great working order regardless of its age. At the last few visits an upgrade was recommended by the technician.

Nancy Bowen

HVAC technician/installer Joe from Sure Temp was excellent! Joe walked me through the procedures of the installation of our Mitsubishi heat pump unit. Joe went above the call of duty and we are pleased with the end result which was exactly as promised. Our historic home's attic is now the most comfortable floor in the house. Thank you Sure Temp, I am already letting others know about our stellar experience.

Andre Abaya

I do need in case the furnace doesn't work or need cleaning........information about someone available in an emergency

Jacqueline Yuzzi

Excellent job. Very satisfied.

Bernard Karpf

Great salesperson, good information provided. Installation was timely and professional. Great experience overall. Very pleased.

Ben and Sarah Dvorsky

All work completed professionally. Cookies in cooler - great idea.

Anonymous Customer

My only regret is that I did not purchase sooner!! My family is so happy with the ductless AC unit- a life changer! These are so quiet, comfortable, and make our life so much easier! We don't need to turn up the TV, worry about which fan, AC unit is on or off- etc. We could not be happier! Love them!!

Mr. and Mrs. Bobik

We are very pleased with the whole experience.

Robin Perry

I have heat in my home without burning kerosine. I have not had a chance to read the manual left here by the installers. I will.

Scott and Brandon did a great job. Very considerate of our home which was appreciated!

Mr. and Mrs. Bartholomew

I ran into Tom Miller at the Home Show this past March, and he called out to me. I was a substitute teacher at Chenango Forks and he was one of my students. We had a good conversation so I later asked him for an estimate. Your estimate was in the ballpark, and Tom's people skills and prompt communication sealed the deal. It was a great experience all the way around. Thanks !

Robert and Susan Wedlake

We are very happy that we went with your company. Our sales person, Tom was extremely professional. So far, we are extremely happy with our product. I would highly recommend this company to my friends and family.

I was able to get an appt the next day to fix my water softener. The technician was efficient and fixed the issue quickly. Would recommend. The only thing that would have been better is if I could have had a same day appt.
