AC died on a Tuesday morning with the heat index at 104. I called at 9, Marcus was here by 1. Bad capacitor, fixed in 40 minutes, and he showed me photos of the old part. The price he quoted was exactly what I paid.

We replaced both systems in our Skybrook house. The advisor measured every room and actually recommended a smaller upstairs unit than we had. He was right. The bonus room is finally comfortable and our July bill dropped noticeably. Install crew was tidy and done in a day and a half.

Our basement always smelled musty. Tasha measured humidity in every room, found it was sitting around 64 percent downstairs, and explained why before recommending anything. The whole-home dehumidifier made a huge difference within a week. No more damp towels.

Been in the Comfort Club three years. Last August our upstairs unit quit on a Saturday and they had someone here that afternoon with no overtime charge. The spring and fall tune-ups get scheduled for me, which I would never remember on my own.

We live in a 1938 house in Dilworth and the back bedroom was always 8 degrees warmer. Andre crawled under the house and found two ducts completely disconnected. He sent me photos from the crawl space before and after. Room is finally even with the rest of the house.

Switched our old AC to a heat pump and kept the gas furnace as backup. Luis explained the changeover setting in plain English and set it up on the thermostat for us. First winter bill came in lower than last year even with that cold week in January.

Water was dripping through the ceiling under our attic unit. They came same day, cleared the clogged drain line and added a float switch so it shuts off next time instead of leaking. Honest, quick, and they did not try to sell me anything I did not need.

Furnace would not light during the first cold snap. Technician was great and fixed the flame sensor quickly. Only reason for four stars is the arrival window got pushed about an hour since they were slammed that day, but they texted to let me know.

Renata came out herself to walk us through three options for our 22-year-old system. No pressure at all. We chose the two-stage option and used the monthly payment plan. The house is quieter and far less sticky than before. The 30-day follow-up visit was a nice touch.

Booked online at 10:30, tech arrived by 2. Outdoor fan motor had seized. He had the part on the van and had us cooling again before dinner. Clear flat price upfront, and he walked me through changing my own filter while he was here.

I am 81 and live alone in Cotswold. When my heat went out on a Sunday night they had someone at my door within two hours. Andre was patient, explained everything slowly and even checked my carbon monoxide detector batteries before he left.

Upstairs was always hot. Another company told us we needed a second system. Calloway tested airflow, found crushed flex duct in the attic and a missing return in the master. Fixed both for a fraction of what a new system would have cost.

Our lake house sits empty for weeks at a time and the lower level was getting musty. They installed a dehumidifier and a water sensor under the air handler that texts us if anything backs up. Real peace of mind when we are away.

Original builder system in our Kingsley house finally gave out after 16 years. They handled the York County permit and inspection, installed in one day and cleaned up like they were never here. Chris even called the next week to check in.

The spring tune-up caught a swelling capacitor before it failed. Tasha showed me the bulge on the old one. With the member discount the replacement was cheap, and I did not have to wait for a breakdown in July to find out.

We have three systems and needed to replace one. They helped us plan the other two over the next few years so we are not caught off guard. The new variable-speed heat pump is so quiet I checked twice to see if it was running.

Good experience overall. They added a media filter cabinet and it has helped a lot with spring pollen. Pricing was fair and clearly explained. Scheduling the install took a little longer than I hoped in the spring rush, but the work itself was excellent.

Luis diagnosed a refrigerant leak on our 9-year-old system. Instead of just topping it off, he found the leak at a fitting, repaired it and showed me the pressure readings after. Straight shooter. First company I have used that did not just add refrigerant and leave.

Heat pump was blowing cool air in heating mode. Marcus replaced a failed defrost sensor and explained what the steam off the outdoor unit means so I would not worry next time. Friendly, on time and the price matched the quote.

Got three quotes. Calloway was not the cheapest, but they were the only ones who did a real load calculation and included a new line set, permits and a 10-year labor warranty. Six months in, the house is more comfortable than it has ever been.
