AC died on a Friday at 4pm in July. Called Summit and they had a tech at my house by 7pm. Fixed it same night. Absolutely incredible service. The tech was polite, explained the issue, and didn't try to sell me anything I didn't need.

We've used Summit for 8 years. They've replaced our furnace, installed a new AC, and do our yearly tune-ups. Never once a bad experience. Honest people who do honest work.

The tech explained everything clearly, didn't try to upsell me, and had it fixed in under an hour. Priced fairly. I'll never use anyone else. Summit is the real deal.

New furnace installed in one day. The crew showed up on time, covered my floors, and cleaned up everything when they were done. The new system is whisper quiet. Very impressed with the whole process.

Great work on our AC repair. Only reason for 4 stars is the scheduling window was broad (8am-12pm) and they arrived closer to noon. But the work itself was excellent and the price was fair.

Called at 2am when our furnace stopped working in January. Someone answered the phone immediately and had a tech at our house within the hour. Fixed a bad ignitor and we were warm again by 4am. Life savers.
