From what I could tell Jeremiah was excellent. Very professional and thorough. Explained everything well and the level of documentation provided was beyond what I have ever received before - photos, explanation, detailed report with results of each test etc. He provided good advice on further measures to ensure system longevity and comfort. Thank you Jeremiah and O'Leary's.

Oh my gosh, my family is loving a warm house now! 😊
I can’t say enough good things about O’Leary Air. We had an old furnace that was not only inadequate for heating our home, but was becoming a fire safety concern.
The fine folks at O’Leary Air came out to the house to assess my old heating unit and they knew exactly what to replace my archaic system with in order to adequately heat my house and economical options.
They replaced my furnace and my thermostat as well (a user-friendly one that’s illuminated). 😊
Their knowledge and professionalism from the initial assessment, to scheduling and installation, was top notch from start to finish.
Thank you team O'Leary Air!!!
