"Absolute ripoff, along with shady business practices. They were prompt and courteous, but that's about it. The technician came and had to replace a $200 part on my boiler, it took him under an hour to do the work. A simple Google search showed at least 10 places to buy the exact part, all around $200. No other parts were needed for this repair, I researched what is involved. I was charged almost $1000, including their $89 diagnostic fee just to walk in the door. So apparently it's a $600+/hour labor rate? I'm obviously in the wrong line of work. This was not an off hours emergency call either, it was a scheduled appointment in the middle of a weekday. The shadiest part of the entire thing was that on the invoice (that they email you later) they bury all the cost, it's not itemized i.e. labor vs parts cost. It just says replaced (part) = $1000. A super scummy and shady way to run a "professional" business, taking advantage of people who don't know any better. I wouldn't be surprised if they also sell used cars. Never again Gervais. You've all been warned."

"He reattached the air condition hose to the vent but never came back with the part he said I needed and would not return my calls. He never finished the job. I hired someone else to complete his work. Beware."

"Bought a heat pump from them 3 years ago. Cooling has never worked in the summer, heating fails twice every year in winter. Even when it works it can't heat the house over 65 degrees. The problem is always the same, a leak in the line they installed. Instead of fixing the leak, they refill the refrigerant every time and charge me a few hundred dollars. Every time I have helpfully told them about the continuing leak issue, but they don't listen. Now that the heat pump is out of warranty they are recommending a $3000 repair of the problem they should have fixed three years ago."

Heating and Air Conditioning questions, answered by experts

A new HVAC system can add 5% to 7% to your home’s value, especially if you upgrade the entire system, including ductwork and insulation. In total, these upgrades could bring around a 30% return on investment (ROI). Add a smart home thermostat, and your home’s value could increase because the heating and cooling systems are more modern, efficient, and convenient.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.
