From a quick reply of my initial inquiry to detailing every step of the process, this gentleman provided a very accurate itinerary of how the repair would be conducted and did just that. Ultimately we now have a cool home and a very satisfied pair of customers that would highly recommend to employ this company to assist with their HVAC needs."

"Emily was the product manager - she assessed the insulation we had, which was very inadequate, and gave us a range of upgrade options. A team of three guys did the work, solving some of our problems in a very resrouceful way. Then Emily came back and checked everything over. We were very happy with both the work performed and the customer service. The house feels unusually toasty now. We'll update this review in the spring after we see if we get our usual ice dams - hoping they're gone forever."

Heating and Air Conditioning questions, answered by experts

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

Many factors affect how much adding air conditioning will cost you, from the size of your home to the size, type, brand, and installation specifics of the system itself. Chances are, a new central air conditioning system for a 2,000-square-foot house will cost somewhere between $3,900 and $7,900 to install, with an average around $6,000. 

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.
