"Got the job done. I don’t know if it could’ve been a little more in depth. They kind of just sprayed it with a cleaner and checked the temps, and a few weeks later, my AC is now dripping water."

"Perfect! The technician arrived on time. He was very efficient, courteous and professional. I showed him where the dryer and outside vent were and went back to work in my home office. Shortly later he told me it was finished. He had done the following: - Showed me pictures and videos of the work that he had performed - Of particular interest was the 'before-and-after" picture of the inside of the dryer duct, which had been clogged with lint - He cleaned out the dryer inside-filter - He swept and vacuumed the area between the dryer and the wall - He put a screw in the dryer vent hose that had been missing - He installed the outside bird-guard that had fallen on the deck months ago I would like to use Duct Kings again to clean out my home AC ducting."

"David Sampaio from SumZero was one of six contractors we interviewed for central AC replacement. David was very helpful in our decision making process when we were deciding between AC and heat pump units. His price was very reasonable too. We chose the heat pump in the end and are very happy with the choice. David’s team was very polite and professional during installation, they did an excellent job setting everything up and cleaning the area. High five, David! Thank you!"

"Service was great from the initial call to book and appointment to the AC tune up appointment. I received a text when the tech was on the way and then a call from the tech when he was 10 minutes away. The tech, Terry, was professional and respectful of my home. He was concise and went through the service report and took the time to answer questions. They are responsibly priced and reliable."

Air Conditioning FAQs, answered by experts

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.
