"Branden came out to our house to review the electrical system, install new outdoor floodlights, and make some other minor electrical fixes. He was professional, pleasant and funny, and figured out how to do the work within our budget. Would definitely recommend him."

"We are very happy with the work that was done by Unique installing a new gas boiler and tying it into our 1940’s hot water heating system. The estimator Mike, took time measuring every room to be sure we get just the right size unit needed for our house. (An estimator, from another company, didn’t size all the rooms, wanted to put in a smaller boiler and at a higher cost!). The installation was painless. The work was done in one day which included removal of our old system. The new system is extremely efficient and we already have noticed significant savings on gas and electric. Great company to deal with. Would highly recommend."

"On the price, I don't, but it was also reasonable. They had also installed a water heater like a year before, reasonable. For sure they're a good service provider, any issues I have with the HVAC or my water system, I'll go to them. They clean up behind themselves; I don't have to do much."

"It was late afternoon on Friday, and a holiday weekend, when I noticed that my house was getting warmer. Two AC companies came up on Home Advisor. The first company sent an email with a calendar for a Monday appt. Right after I pushed the send button my phone was ringing. The second company, One Hour Heating and AC , was calling to setup an appointment for that day. Hunter showed up at 9pm(drove about an hour from York). He didn't have good news for us but he was very nice and explained the problem and our options thoroughly. Today, Saturday, Jerry came to explain our options for a new A/C. Hopefully we are getting a reasonable price and a good product. I guess time will tell but the people that I have talked to on the phone and the men who have come to my house have been very nice and professional to deal with. Our new A/C will be installed on Tuesday. Because we have to provide a star rating I'm only putting 3 out of 5 stars for value for money. I do not know how to rate this because the A/C hasn't even been installed yet. If we are happy with everything I will edit or update this rating at a later time."

"Patriot was awesome from the start. I got 3 estimates for the same Trane AC units, removal of 2 very old systems and install of 2 new systems and they were the best price by far and offered a 2 year labor warranty on top of it. The removal and install went great and Will wouldn’t leave until I was 100% satisfied with everything. Highly recommend them for any heating or air conditioning needs."

"

We found Frank on craigslist and I did a lot of homework before we decided on him. He promptly came out for an initial estimate.

He could have not have been any more understanding or nicer. He listen to what we needed and then gave me several different options.

No pressure sale B.S. He knows his stuff inside and out.

Gave a deposit and a week later the work was done. Everything looks great.

Only time will tell about the unit but Frank has made a customer for life.

I never write these reviews but felt that the negative review he already had did not warrant his

overall services.

"It took 2 days to do the work. Larry and his crew went meticulously piece by piece and installed all the new equipment. They did it so quietly, neatly and perfectly, it was as if they were not there. Any item that needed my imput , such as location of thermostat, they asked questions to clarify. I could not have been happier with their professionalism, politeness, and quality of work."

"Ephraim cleaned the dryer and dryer vent efficiently. We then spoke at length about our HVAC system and cleaning the ductwork. Efy found mold in our system air handlers, made suggestions for taking care of the issue, and cleaned the ductwork. He was terrific... knowledgable, and efficient!"
