Here is what some of your neighbors have to say about our work

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.

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.

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.

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.

Great team and dependable.

Heating and Air Conditioning Service

The old saying prevention is better than cure applies most certainly to HVAC systems. While we’re always happy to come out to fix your system when you need us, we’d be even happier if it never needed to be fixed, and you probably would be, too. Although we are committed to fair pricing and we’re transparent in everything we do, it’s a simple fact that a major repair during peak season will always be more expensive than an off-season tune up.

With our preventative maintenance plans, you can have one of our trained technicians come out to check your system during mild fall or spring weather. They’ll correct any small issues that are decreasing your system’s efficiency and increasing your power bill. They’ll also perform a thorough inspection to see whether any parts need adjusting so that a minor problem doesn’t turn into a costly outage.

We also offer custom design sheet metal services, AeroSeal duct sealing to increase your forced-air system’s efficiency and provide free in-home estimates on all HVAC jobs.

Whether you need air conditioning service, repair, or installation, give Ireland Heating & Air Conditioning a call today.

Heating and Air Conditioning Repair

Even the best HVAC systems eventually need repair. Heaters and air conditioners are no different than any other complex pieces of machinery. Even a system that is built to last will need some sort of repair after thousands of hours per year of hard work keeping you comfortable.

Whether your system is still under warranty or is an older model that you’d like to keep going for a few more years, when you need air conditioning and heating repair, we’re here to help. We have convenient office hours to discuss minor issues, and if your cooling has gone out in the middle of the summer or your heat has gone out in the middle of the winter, you can call our emergency hotline at any time of day or night. We’ll send someone out as soon as possible along with the tools they’ll need to get your systems up and running again. And, just because we’re a proud Carrier dealer doesn’t mean we don’t work on other systems. Our technicians can service any make and model out there.
