"Steven hung 4 sets of curtains on my 10 ft tall windows — something I definitely couldn’t have done living in in apartment. He was quick, responsive to texts, and did an excellent job! Will definitely be using him again in the future for other household tasks "

"Clint started off strong as a handyman. His workmanship was excellent, his rates were fair, and he was pleasant to work with. Unfortunately, there began to be recurring issues with schedule management and timely communication, which negatively impacted my projects. A miscommunication ultimately led to offense being taken, and he abruptly discontinued work via text without notice to my surprise. Disappointed though I am, I?m thankful for the work he was able to do and wish him all the best as I start the process again to secure another handyman for my remaining items and to have on hand for regular maintenance in the long term.

Heating and Air Conditioning questions, answered by experts

To find a reputable HVAC company, start by finding providers in your area that have mostly positive reviews online. Next, check the Better Business Bureau’s website for customer complaints. Some states and municipalities require technicians to be licensed, so you should rule out companies that aren’t. Finally, contact each professional and ask for per-hour pricing, contract availability, and references to call. You can also ask if they have worked on your particular system brand in the past to confirm that they’re qualified.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

Yes, adding central air can increase your home value by as much as 10%. Generally speaking, prospective buyers prefer a central AC system over a ductless system or room-by-room AC units. That’s because central air conditioning blends into the home easier than individual room air conditioners and typically has less equipment to maintain.

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.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.
