Murphy's HVAC describes itself on HomeAdvisor as having more than 20 years of experience. A recent customer says the install went well and the trouble came after. That customer says the company sold them Samsung split-system equipment averaging two years old, that problems began in 2024, and that through all of 2025 they had no AC and no heat, which the company could not fix on many attempts. The customer had a new company install different equipment and puts the loss at over $15,000. A 2019 customer said Tim Murphy, the owner, called directly, made an appointment for that afternoon and never changed his quote. A 2019 reviewer wrote that Tim gave the best price of three estimates, that they were on the schedule in less than two weeks and that the work was completed in a couple days; that customer said they were enjoying their mini split air conditioners. A 2019 customer said Tim removed and replaced their oil tanks.
Nice enough guys - Install-Great, probs after. Sold old Samsung equip avg 2yrs old, wanted to get rid of it[?]. Didn't know til ck'd dates on equip way after install. OK 2023. Numerous probs 24. All of 2025-No AC, no heat, they could not fix on many attempts. Kind of left us. Got rid of equip, had new co. install new, different equip. Samsung is NOT a good split system. Constant issues [cuz 2y/o?] Who knows, they're gone, all new. Bottom line, wasted over $15,000!!!!
They did a very great job, very happy with the service.
Tim removed and replaced our oil tanks. Hard working, professional, always got back to you in timely manner.
Tim came for an estimate and gave the best price I got out of three estimates. He was very knowledgeable and knew what was needed and how long it would take to get the job done. I was on the schedule in less than 2 weeks and the work was completed in a couple days. Thoroughly enjoying my mini split air conditioners. I would recommend Murphys HVAC to anyone in the Northwood area, great price great service and attention to detail.
Tim Murphy, owner, called me directly and made an appointment for that afternoon to meet. He kept his word; never changed his quote and kept me informed despite skepticism. I was in a vulnerable position but Tim was nothing less than understanding and most professional; old school. Thank you Home Advisor for being my portal to Murphy's HVAC
