What Worcester says

“

Our AC completely stopped during the July heatwave and Seven Hills had a tech at our door in under two hours. He explained everything before touching a thing — no surprise charges.

★★★★★
“

Called at 1am when our furnace died and someone actually picked up. Fixed by 3am. That's the kind of service you remember on the coldest night of the year.

★★★★★
“

Got quotes from three companies for a new AC install. Seven Hills wasn't the cheapest, but they were the only ones who didn't try to upsell us on a bigger unit than we needed.

★★★★★
“

Been using them for 4 years now for our furnace tune-ups. Same technician every time, which says a lot about how they treat their employees.

★★★★★
“

Emergency heat repair on Christmas Eve. They still charged the flat rate they quoted over the phone — no holiday markup, no games.

★★★★★
“

Financing made replacing our 20-year-old furnace actually doable this winter. Install was clean and finished in a single day.

★★★★★
“

Our triple-decker's old system was a nightmare for three different companies before Seven Hills figured out the real problem in one visit.

★★★★★
“

Professional, on time, and didn't leave a mess. Explained the AC repair in plain English instead of trying to confuse us with jargon.

★★★★★
“

Booked an AC install online and got a callback within the hour. Whole crew was respectful of our home and cleaned up after themselves.

★★★★★
“

Called around 9pm on a Sunday about no heat. Tech showed up the same night. Didn't expect that from a company that answers its own phones.

★★★★★
“

They found a warranty issue on our furnace that the manufacturer covered, saving us almost $400. Could've easily just charged us for the part.

★★★★★
“

Honest pricing from the first call. No pressure to buy anything extra, which is rare to find in this industry these days.

★★★★★
“

Our AC was blowing warm air for a week before we called. Turned out to be a simple fix — they didn't try to sell us a new unit we didn't need.

★★★★★
“

Great experience start to finish. Got a text reminder before the appointment and the technician called 20 minutes out, just like they said.

★★★★★
“

Furnace repair scheduled for the next morning, tech was in and out in 45 minutes. Heat was back on before the kids got home from school.

★★★★★
“

Switched to Seven Hills after our old HVAC company stopped answering calls entirely. Night and day difference in communication.
