This is what our customers are saying about us.

  • “When we asked that the units be replaced as soon as possible, there was not any hesitation by Shamrock. They were efficient and very knowledgeable of the products they were working with. I am pleased with the outcome.”
  • “Sean did an outstanding job. I highly recommend Shamrock and will use again Thanks!”
  • “Shamrock called and came out at the scheduled time for the appointment set up for my quote. The other contractors never showed up for their appointments, nor did they call to cancel. I ended up getting 3 quotes from independent sources, but Shamrock still beat their prices. Shamrock is what I expected from a company and will continue to get my business and referrals.”
  • “Sean gave us a screaming deal on a brand new 13 SEER 3.5 ton unit. He also did some duct work and installed the new unit in a day. He was fast, reliable and personable and we had a great experience. We will need some additional work on a different part of the house and will definitely call them.”
  • “Replaced a relay in the air conditioner unit and checked the Freon. Was here in short order and gone in less than 1/2 hour”

I in my third service contract with Shamrock. They come two times a year and tune up system keeping it in great shape. The quality of service, attention, and care that Sean and the other technicians have given my home and sytstem has been unmatched by previous companies. This time we had a breakdown of my older system, they worked with my home buyers warranty with no problem, and my home buyers warranty worked with them no problem. That’s really nice! What I appreciate the most is that they treat my system like it was their own. For that I will use them for life and recommend them to anyone. Thanks Shamrock for a job that is always well done!

Over the years I have met many Shamrock techs. They have all been very professional and very competent. Yesterday, my service contract work was performed by Darol, who told me that he is a recent graduate in the HVAC industry. With such short experience, I must say that Darol is one of the most conscientious and poised professionals that I have ever had the pleasure of meeting. I am a retired executive of a plumbing and HVAC manufacturer, and as such, I have met and worked with many tradespeople. Shamrock, in my opinion, is the best of the best, and they proved it again when they hired Darol.

Sean and Linda are great to work with. They are great with their prices and so fast and efficient. Couldn’t ask for a more honest company to deal with. They take pride in their work and care about the customer! I will call them anytime I need something done!

Neil came out to do a yearly check on my AC unit and he did a fantastic job. He was on time and checked all the parts of the system and there was no nonsense, no “You need to replace”. He was courteous and fast and a very nice person to deal with. I would invite anyone to give them a try, you won’t be sorry!

Sean did a GREAT job for my a/c. He made recommendations on long-term solutions, service agreements, and general maintenance, as well as servicing all of my immediate a/c issues. Very knowledgeable. Showed up when expected. Very courteous. Will definitely recommend this company, and this plumber, to anyone who needs heating or a/c assistance! Thanks Sean.

Shamrock employees are friendly, courteous, and prompt. Their service/product was high quality at a reasonable price. I highly recommend Shamrock to anyone in need of heating and/or cooling services.

My air had stopped working while I was at work sometime on a Friday & Shamrock was able to fit me in the next day (Saturday)! Joey was able to fix my air conitioning unit in literally 5 min so that my home was no longer 96 degrees =D He was professional, courteous, & willing to answer any questions I had. I will absolutely use this company again & have already recommended them to several friends & co-workers. Thank you guys very much!!!

Had a/c problems over the weekend and they told us they would be out between 2:00 and 4:00 on Sunday and they were. Leigh was very nice and super informative. We are enjoying a cool house tonight. Thanks!

Due to hail damage we needed a new heat pump. Craig came out the first time to check on it and then he and Joey came today to install. They were to be here between 2-4 and were here at 11:30. The job was to be finished by 5-5:30 and by 2:30 the unit was up and running. Professional, courteous and knowledgeable, what more could you ask of a company. Would we recommend this company to other people…….. HECK YES!!!! The other thing we were imopressed with, they gave our 3 1/2 year old grandson a bag with a toy and flashlights. So besides us, they took care of our little one. FANTASTIC COMPANY. Thank you everyone at Shamrock and keep up the great work. Our special thanks to Craig and Joey.

We used the Shamrock 11.95 a month plan for the past 2 years. Our unit was 10yrs. old. Our service man Joey was always on time or would call if he got stuck on a job. Joey gave us the bad news on Friday morning (bad compressor) and the choices. They gave us bid for a 15 cere 5 ton and Monday for installation. They lower than other bids. Most important was it could be done Monday, my wife just had surgery.The installation was an all day process starting at 8:00 and finishing at 6:00. Craig & Easton were great!!

Shamrock did an outstanding job on replacing our EVAP cooler. Sean,Tom and entire crew gave fantastic service. I would recommend them to any one for your heating or cooling needs.

The technician from Shamrock spent 4 hours at my house diagnosing and correcting my air conditioning problem. I have had 5 technicians at my home during the past 2 years and this is the first time the problem was thouroughly diagnosed and taken care of…I am a very pleased customer.

Today 10/10/13, Rocky Cocciolo was the service technician who repaired our air conditioner.  He was efficient, pleasant and his workmanship was great. Thank you, Rocky!

I called Shamrock in a panic because our unit started blowing hot air! They sent Sean out within 45 min and he got the unit working again in no time…
