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

Matthew G.

Our heat went out during a blizzard and negative temperatures the day before we have a huge group coming for the holidays. Iris in the office was amazing on the phone, and they were able to get me a technician at the last minute. David came and fixed everything quick and easy, showed me some good stuff about my system. And was overall very professional and helpful. They helped me out of a jam, so I will be a customer forever. Thank you!

Frederick F.

Just had Mike out to fix my AC unit and he was wonderful. The ladies in the office were very nice and were able to get someone out fast. When Mike came out he was very knowledgeable and professional. I would highly recommend them!

James L.

Awesome service! I called them tonight to report that my A/C wouldn’t come on. The technician came over within the hour and determined that my thermostat was broken. He replaced it and my air was on within an hour! I thought I would have to schedule a service later in the week…nice surprise! Thanks again guys!!

Heating and Air Cooling 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 Cooling 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.
