He didn't have the exact part we needed but he was able to get us up and running with a temp fix. He came back next day with the correct part and got it installed.

Also, he didn't try to upsell us on anything like many HVAC companies do these days. I highly recommend him and Delta T.

Made an appointment. They didn't show during the 2-hour window and didn't let me know they'd be…read morelate. When I called in to find out what was going on, they had an AI assistant answer the phone that barely worked. They finally called me back, put me on hold for a while, and then said they'd be at least another hour. Seems like this company is too big for its britches. I won't be hiring them again--going back to a smaller company that actually cares about the customer. What's my issue? I scheduled an appointment and burned afternoon PTO waiting during a 2-hour window. No one showed, and no one bothered to call. When I reached out twice, I was trapped in a completely unhelpful, robotic AI assistant from India that failed to handle basic routing. After being placed on hold and disconnected (the AI said they would call back), I finally got a call back from operations--only to be told the tech was running another hour late (which would have been 1 and 1/2 hrs past the window). When I expressed reasonable frustration over a wasted afternoon and said this was ridiculous, the dispatcher offered zero empathy or accountability, gave a cold "Okay, bye," and hung up. If your techs are running behind, basic field operations dictating contacting the customer 45 minutes ahead of time--not leaving them in the dark, wasting their time, and hiding behind cold script readers and a robotic AI. Unacceptable way to treat customers. Here is a basic operations communication map Step 1: Appointment Scheduled & Tech En Route * Field Assessment: Tech assesses job progress 45-60 minutes prior to the next window. * On Schedule? Proceed to customer site. * Behind Schedule? Trigger proactive dispatch notification. Step 2: Proactive Customer Outreach (Before Window Lapses) * Tech or Operations sends a quick SMS/Call: "We're running ~30-45 mins behind on our current job. So sorry for the delay! Would you like us to come slightly later today, or would you prefer to reschedule at your convenience?" * Option A: Customer Accepts Delay -Tech proceeds; Operations tracks ETA. * Option B: Customer Reschedules -Immediate priority re-booking with zero hassle and empathy. Step 3: Inbound Customer Inquiries (If Delayed) * Customer calls in regarding status -Route directly to a live dispatcher (bypass automated bots for active appointment windows). * Dispatch Response Track: * Cold & Callous Track: Put customer on hold - Minimal explanation - Dismiss frustration -Customer cancels & leaves 1-star review. * Warmth & Empathy Track: Validate lost time/PTO - Provide precise ETA - Offer immediate service fee credit/discount for the hassle - Return to Step 1 for future service. ... It's not that hard.

We were so hopeful when Marc came through and provided us with a good and reasonable estimate. He…read moresaid upon signing the agreement our system would be installed within 10 days. NOT THE CASE. Weeks after signing we had our appointment coming up for them to reschedule on us last minute.. not a big deal end of week adjustment is alright. Then today Thursday (6/29/23) they called to reschedule for our appointment tomorrow AGAIN. Next available is July 19, 2023! This company is disorganized, unprofessional and the front office needs to figure it out. Not sure if Marc and the sales teams are over promising and Dalco under delivering, but we won't be taken advantage and just go with a estimate that was almost identical. I'd say steer clear for a while and hopefully they figure out how to schedule clients and run a smooth business.

The tech came out and told us it would be $1500 to take apart the furnace and clean it, and that it wasn't worth it. That we should pony up for a new $6-$7K furnace.

We got the furnace taken apart and cleaned for a couple hundred bucks. A/C is cranking. Beware of these types of shady practices.

While the technicians themselves were friendly, my overall experience with Summit was disappointing…read more-- particularly given that they had been highly recommended by a neighbor. After the fourth visit and two failed inspections, I asked to speak with the owner. He said he'd show up on the final day and didn't. Not showing up after committing to do so speaks volumes. On multiple occasions, employees attempted to -- or did -- walk through my home beyond where work was being completed with their shoes on. This is a basic courtesy that should not have needed to be addressed. On the final day, an employee complained about the time spent waiting for the inspector to arrive. After five+ weeks of doing exactly that myself, I couldn't help but laugh internally. Most importantly, Summit advertises a "100% Right or 100% Free" guarantee on their website. These are not complicated words -- 100% means 100%, and free means free. There is no secondary meaning to either. When I raised this, I was told it essentially means they will keep trying until the job is done correctly -- which is admirable in theory, but falls well short of what "100% Free" implies when a customer has invested THOUSANDS of dollars. After reading the other reviews, I'm hoping the problem with my AC wasn't just a leak somewhere that could have been fixed for much less. I would strongly encourage potential customers to clarify what that guarantee truly means before signing a contract, and to get everything in writing.
