"I highly recommend this company. Penguin heating & Air was very quick to respond to my request, fast text reply, sent them pics, they replied with a quote, which was way lower than anyone else on this site, or even our regular guy that we normally use, we scheduled an appointment for the very next day, which was today, he also finished the job the same day! David did a very good job, very professional. Despite a terrible rainy day, he got the job done. When he was done he walked me through with exactly what he did. He also quoted me for a service on an existing unit and his quote was almost $200 less than what our regular guy charges us... We will absolutely be using this company again."

"Fast efficient service. Left the job area very clean. My only complaint is they don't provide a breakdown of the bill; parts/materials and labor costs. Not cheap, but their work is top notch."

"Needed a new lock for the kitchen door. Jaime set a time for an estimate. He arrived within the time frame, gave an estimate to include purchasing the new lock. Purchased the lock and installed it. When he finished, he cleaned up very well. Would definitely use him again when I need a handyman."
