I do everything I can to avoid writing bad reviews for local businesses, but Ireland earned this one. After reading their stellar reviews here, I called them about a fairly straightforward HVAC replacement to help fix a heat/humidity issue we were having in the house, only to be told that wasn’t the issue (even though my unit was over 20 years old) and what I *really* needed was a bunch of additional insulation, new exterior soffit vents, a new return vent, and more to the tune of over $7000. I was skeptical but Ireland’s owner was insistent and I decided to trust the experts.
After all of that work was conducted, there was zero noticeable change in our issue - truly, zero. I first emailed to express my disappointment and frustration and was ignored for over a week. I then called them, and while trying to state my case firmly but professionally and factually, I was gaslighted into thinking it was somehow my fault that this issue wasn’t resolved, and that it still couldn’t be my 20+ year old unit that was part of the problem. After that unproductive conversation, I was told by the owner that they would follow up with me again shortly with potential remedies - only for them to completely ghost me.
I have had pleasant professional working experiences with just about every home services company/contractor I have ever hired - my review history will confirm this - but this was one the only times I felt like I was led astray by a company was too proud (or greedy?) to admit they led me down the wrong path.
For the record, most of their associates I worked with were friendly, knowledgeable, and helpful - the issue is with the people at the top.

I have been using these guys for over 4yrs and have not had any problems with my AC or Furnance. I bought the PM package and it’s well worth it.
Highly recommend these guys.

Ireland showed up on time and serviced our rooftop furnace quickly at a reasonable price. The technician took time to explain the problem and how to prevent it from recurring. Excellent customer service, will definitely use them again.

This company is friendly, reliable, and efficient. Everything from booking with Kyle to having The same technician come out – Joe – who is very good and professional. Diagnosed and fixed my furnace problem quickly. Repair was done and haven’t had any problem with it. I use this company for maintenance and Joe always comes out. I would recommend this company.
