2 years ago Shamrock installed a hot water tank. Great job!. So when I needed a new furnace and AC. I got 5 bids. Shamrocks bid was the lowest, with the best equipment, and best installers, and the best bid. They are the BEST!!

I called and they called me back in ten minutes. A guy came out that same day. Even though it seemed pricey, I decided to replace the A/C condenser and coil. They came back and installed it first thing the next morning. Rob was extremely professional and punctual, which I really appreciated. I feel like I paid a little more than if I had shopped around, but they got the job done fast and did what they said they were going to. So it seems like money well spent.

Did not have part as A/C unit is 30 yrs. old. Returned next day with part. Took a while to figure out how to wire up. Also performed inspection and tune up of unit - 3 hours total .Discovered that night that unit would not shut off. Called next day and someone else came out to figure out the problem. Problem finally resolved after 3 hours. Has been running great since then.
Description of Work: A/C would not turn on. Found out transformer burned up after turning unit on due to animal chewing through outside wiring.

We elected to do a recharge only (without finding and repairing the leak) and not put any more money into our old and outdated system. Time will tell if it was a good decision.

Todd and Chris of Shamrock Heating and Air Conditioning have been wonderful to us. We bought a new heating and air conditioning unit back in 2012. This year the heater started acting sporadically. They came out immediately and determined the circuit board was the problem. They replaced it no charge. We are very pleased with our investment.

Very well, the tech was friendly and professional and gave me a impression of honesty. However, the price on installing a new system was a bit misleading. The advertised price didn't include labor For the installation.

Woke up with the house cold. Furnace was out. Spent a good while tinkering with it myself - we have a lousy old furnace. Tried a few things but couldn't figure it out, so I called Shamrock. Glad they were able to get a guy out within a couple of hours on the Saturday of Thanksgiving weekend - no complaints there! It took the technician a while to figure out what was wrong, but eventually he replaced the control module and that solved the problem. So we've got heat again. BUT. The part he replaced costs 96 bucks online. Shamrock charged 347 for it. That's a huge markup - even for HVAC. The technician offered to put the old busted module back in so I could replace it myself. I thought about it, but opted to go ahead and pay. I don't think the technician knew the markup would be so much. But I wish he'd given me at least a ball park estimate what the cost was going to be. And I wish his company wouldn't gauge customers so bad for parts. Good repairman, but bad experience overall.
Description of Work: Made service call to investigate non-functioning furnace. Eventually replaced bad furnace control module.

They've been wonderful. We use them every 6 months. One flaw that I found was they didn't catch was that we had a lot of leaks in the duct work around our furnace and our crawl space and I ended up having to do that myself, we didn't follow up with them to ask them why they didn't check on it but that's something that I caught like 2 months ago or so and I repaired that myself. They've been great and we've been using them before we moved here, we used them in our old place. Their cleaning service is phenomenal and it's not nasty, I know there's a lot of people who don't do duct cleaning because they're terrified that the dusts are going to get everywhere in the house and we have zero clean-up after they are done. We're paying an annual service fee.
Description of Work: Shamrock Heating & A/C do our duct cleaning every 6 months. They also replaced our primary furnace a couple of years back.

The call usually runs smoothly. They give me an hour window, and ipon arrival the technician wears plastic on his shoes. They explain any additional services that might be needed either now or in the future. I am very comfortable with this service and use them regularly.
Description of Work: I use Shamrock for the maintenance of both my furnace and air conditioner. One I became confident of their quality and service I signed a maintenance contract with them that provides me with discounts on these services. They are always on time, courteous, and professional. They do not always suggest the ost expensive option, and extended the life of my old furnace by several years.

PLEASE READ THE REVIEWS..note: PRICEY, HIGH, EXPENSIVEGreat Response TimeDO GET A SECOND OPINION. THEY ARE VERY HIGHUnreasonable to deal with for itemized detail of work provided
Description of Work: called with air not working properly, technician did come out next morning ($99 diagnostic fee) told us a part which was still under warranty was faulty, had to drive to pick up part and replace (tech was at our home no more than 1 hour if that). claimed he had to drive 30 min both ways to get a part. installed in less than 20 min and charged an insane charge of $350 PLUS the $99.00 diagnostic fee. called twice for a break down and was told they BUNDLE the price???? so I questioned what did I pay $450.00 for? I wanted an itemized breakdown. They would not provide and their suggestion of how to resolve was to have the technician come back and remove the part!!!! I believe in a FAIR profit but this was beyond FAIR & REASONABLE. in my opinion they took advantage & even more disturbing is I think they know it and do not care. I can not recommend this company's poor business practices.

Our air conditioning failed on one of the hottest days of the year. I called Shamrock and a pleasant woman asked how she could make my day better. I was told that within 20 minutes a technician would contact me. Dan Breheny called promptly and gave me an estimate of how long it would take to get to my house. He was punctual and courtesy. Unfortunately, Dan confirmed that the compressor in our air conditioner was gone and that we would need a new unit. We feared we would be taken advantage of given the warm weather and Dan assured us that would not be the case. We knew our furnace would need replacing within the next year or two too so we questioned whether their were financial and mechanical benefits to doing both. Dan told us there were. Dan was very knowledgeable about the industry and brands on the market. I really thought Dan knew his stuff. Dan left our house and went out to his van to get pricing. I jumped on the internet to look at pricing for American Standard and was shocked at the prices Dan came back with from the office manager. He said this was the best that the office could do. The pricing was much higher than we expected based on the few minutes of research. Dan explained that it was because we needed a new coil due to environmental changes and labor. We told Dan we would need the night to think about it because it was such a big purchase, but hoped to call him back that night. That night, we went back on Angie's List and found a discount for Angie's list customers that was slightly better than the discount Dan had given us and the pricing seemed out of line with other vendors. So we called several more contractors for an estimate the next morning and ended up going with another contractor. We purchased essentially the same or better unit from another highly rated Angie's List vendor that was fabulous (Trane) verses the American Standard sold by Shamrock for just under 25 % less. Dan's professionalism and knowledge made it difficult to tell him when he followed up the next day that we were not going with Shamrock, but in the end, it appears that Shamrock's pricing was well above market value.

We woke up this morning to no air conditioning and it was the hottest day of the year! We called Shamrock Heating and Air Conditioning and withing one hour, they had someone to diagnose the problem. The service technician was extremely competent, knowledgeable and offered us a couple of options to fit within our family's budget. Within 30 minutes we were back up and running! We saved tons of money by simply replacing a part. We look forward to doing business with Shamrock again and will recommend them to friends and family.

I then called another company and was told that the freon would be $35/lb. (about 1/2 of what Shamrock quoted). I had them come out and they added 3 lbs. of freon at a total cost of $105 (plus the service call). The A/C was working perfectly at that point. He also did a quick leak check for no additional charge, but could not find a leak. A more thorough leak check would have been billed at their standard rate of $22 per quarter hour, but was not recommended. Had it been done, it clearly would have cost FAR less than the $497 that Shamrock quoted. Final bill from the other company was $219, versus what would have been $842 from Shamrock.
Description of Work: I called Shamrock to inspect our home A/C. The unit had been working fine, but had not been inspected in some time, so I figured it was due. The technician (Todd) was very courteous, did the inspection as promised, then proceeded to tell me that the unit was low on freon and it would cost $345 to add 5 lbs. of R22 freon. He also recommended doing a leak test for $497. I knew that those prices were way out of line, so I paid him for the inspection ($99) and told him "no thanks" on the other work.
