We had an extremely difficult AC replacement in a tight attic area. After having terrible experiences with several other companies we called Ireland. Their professionalism was top notch. They were able to explain options for the new installation clearly and simply. When other companies said the job would need a team of guys and take a week- the Ireland team of two came out promptly first thing on day of installation and completed in a few hours. Don't do what I did and call other guys and deal with that mess.call Ireland first and you will be happy.

These guys are A1. They were on time, professional, and very knowledgeable. They repaired my furnace's blower motor and blower fan. After replacing, they tweaked the compressor by adding a bit of refrigerant to fine tune my AC. It was very hot and humid inside and outside and within an hour, the house had already cooled down. Because I am interested in HVAC systems, the technician Rich did not mind that I followed him and asked questions.

Besides being a personable nice guy, Rich knew exactly what to do. Great job Rich! The person who scheduled the appointment. Kyle.kept in touch, was pleasant on the phone and was easy to work with to get Rich out here. Thank you to all for a great experience. I would highly recommend using Ireland Heating and Air Conditioning for all future HVAC needs in my home.

We had a furnace/AC replaced by Ireland in September and just had a whole-house humidifier added. The quality of service on both projects was perfect. There was a minor engineering problem (in no way Ireland's fault) affecting the installation of the humidifier, the problem required extra work on their part, and use of different model of humidifier, yet the project actually came in slightly under the bid cost!

In both projects working with Ireland was a delight. We needed one minor service call after the installation of the furnace - they were prompt, and addressed the issue as warrantee service. These folks are as good as it gets.

I can't say enough about the service I have received through Ireland! When my heat went out, Dave himself came over after hours. I was afraid I would need a new unit, since the HVAC is 18 years old, but he told me with a replacement part and a good cleaning it would be good to go. I appreciate such honesty and dedication to service. Simply the best!

I have been using Ireland Heating for years. Every time a technician comes to the house, he has been friendly, polite, courteous and knowledgeable. Through the years we have needed the occasional repair and one year we needed a new furnace and an air conditioner at the same time. Throughout those experiences I have felt like the owners took the time to educate me on my options and at no time did I feel pressured to make a discussion quickly. I have always felt their pricing was fair and just and that they were willing to help me find a less expensive alternative if needed.

After calling in the morning with a non working ac in one part of the house an accomodating appointment was made that day and fixed w no fuss and efficiency and kindness on part of serviceman. Great team and dependable.

I cannot say enough good things about Ireland Heating. We have been customers for over 20 years, and they have been consistently honest, providing superb service and technical skill. We called them this morning at 8 am- coldest day of the year, a holiday, 8 below zero, and 54 inside. They reacted promptly, got to the house quickly on a holiday, identified and fixed the problem, and had heat pumping again within an hour.

We trust them. They are loyal, dependable, so honest- knowledgeable and hard working, and committed to helping the customer. Dave Ireland and his team provide superior quality in all aspects of their business- including answering the phone on New Years Day at 8 AM. And we are grateful.

Always professional, from customer service/dispatch to service technicians. We use Ireland for scheduled maintenance, and recently had to call them for an unexpected repair. Dispatch was fast, and the tech was punctual and called ahead. Felipe made the repair quickly, explained beforehand what he would check/do and afterwards explained what was done.

He also performed my scheduled maintenance while he was here so that I avoided an additional charge. When all was said and done, I actually felt like I got more for my money than expected. That is a rare commodity when it comes to service, but that has been my consistent experience with Ireland.

Ireland HVAC is an excellent company from the top down.we have been satisfied customers of theirs for many years now. Their service is professional, prompt and thorough.they always take time to explain what needs to be done, and they work hard to get it right the first time. Their technicians are skilled and polite and have become friends. We can highly recommend this company and all of its people.

Excellent Service! I hired Ireland to install AC in my house and they did an excellent job! The technicians were very courteous and knowledgeable. I had to step out for a moment and they went above and beyond and walked around and closed all my windows and called to tell me where they left the paperwork and ask what temperature I wanted it set to. I was so surprised to have my new AC completely installed in one day! The equipment works great! I am very satisfied with the quality of my Carrier Ductless split system.
