My AC went out over the weekend. My preferred repairman was not available so I called Geiler. The only positive is that I called Saturday at 8:00am and he came out by 1:00pm. He told me that me freon was leaking but he couldn't see where from or how much because the lines were frozen. Told me that he doesn't need to check that I just need to replace the unit because refilling the freon alone would be $1000.

The charge for "diagnosing" was $89. At a minimum, he could have offered to come back when they were thawed so I actually had a proper diagnosis. I waited or my normal repair to look at it a few days later and he was able to fix it for $400.

More than pleased with Geiler's service today. They are a union company so you know their guys are trained and qualified to work on your equipment. Chris came out and did a thorough inspection of my heating and air equipment, while performing some needed maintenance as well. Two thumbs up.

Arrived timely and tech was pleasant and professional. Job was to auger sewer line. I understood the $69.00 fee for coming out, estimate, etc., however, I wish Geiler would consider waiving the fee if bid/estimate was accepted, rather than adding on as additional cost. So to auger the drain was "$210.00" plus the $69.00 that I would've felt much better about being waived in exchange for giving them my business; would've been nice and appropriate. I paid $279.00 to have clogged drain cleared. No big deal, but will likely give next plumbing job to plumber who agrees to waive the fee.

Shout out to Dennis, Eric and Kyle for repairing our malfunctioning boiler. Dennis went above and beyond. He is professional, courteous and all around a terrific guy. I don't know what I would have done without him this past week. Geiler is lucky to have him. Thank you! Service: Heating system repair
