They installed my furnace end AC.perfect operation and fast install. Would recommend.

They installed a new furnace and the unit was having issues. I called another company because I rent and did not know who did the install at first and found out they never even hooked up the ground wire on the furnace. The wire was cut and taped to the inside of a panel. The landord then told me it was O'Donnell's that did the install so he called them to see if they would rectify the problem. The owner of O'Donnell's was condescending and vulgar to him. I am now having the company I did hire to repair the furnace sign an affidavit. Even though I rent they put my family at risk with their faulty and illegal install. Companies like this should not be in business.

We had 90+degree weather today and our ac stopped working at noon. We called O'Donnell and a few others to come fix it. O'donnell gave us the best price and came out by 3pm. Not only did Jim fix the problem, but he was fast (about 5 minutes), and didn't try to upsell me anything or try to replace the whole unit. My AC is working great! Jim was friendly, upbeat, honest, and great to do business with. I highly recommend O'Donnell for anyone needing A/C service!

What's new?

It’s that time of year again !! Make sure to call to get your yearly maintenance if you haven’t done so all ready. Make sure you have a clean filter and change your batteries once a year in the thermostat , smoke detectors and carbon monoxide detectors .
