"they said they were going to show up Monday at 9am, after a brief delay not due to them they were here shortly after. he looked at the door and said it wasn't a problem. he proceeded to the store at which he called and stated that he could just get the hinges instead of the whole door and hardware. of course I agreed resulting in saving money. once he returned the door was fixed in a short amount of time. very polite and professional. would definitely use Edgyver again if I have any more handyman projects. thank you to them for doing a great job."

"We had Sunshine Construction install a brand new central A/C system at our home, and I can honestly say the experience exceeded expectations from start to finish. Charlie was our main point of contact and made the whole process easy to understand, super communicative, responsive, and professional. Troy led the install crew and did an amazing job. Everything was done quickly, cleanly, and the system has been running flawlessly ever since. Customer service was top-notch, the team showed up on time, explained every step, and treated our home with care. I’d recommend Sunshine to anyone looking for HVAC work done right the first time."

Heating and Air Conditioning questions, answered by experts

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.
