Fantastic company! Very professional, friendly, communicative, honest and possibly the most important to many customers, very affordable. They were able to work around my limited schedule and sent out a tech, Trevor, the same day, during the evening hours. They originally came out to give me an estimate on replacing my 34 year old furnace, but Trevor was able to get it repaired and operating again, which was a lifesaver during these cold fall days! I will definitely be using them in the next month or so to get our outdated system updated. Thanks again O'leary Air!
