"I had the best experience. It was a super hot day and my air conditioner stopped working (it had given me problems in the past and i knew it was time for a new one). Called Keith Lascos heating and cooling; told them the situation and they said they would be out by my house around 5pm. Not only did they show up on time but they completed the installation the very same night. The price was fair and they answered all my questions and ever since I have had no problems with my AC. It was probably the best experience I've ever had with a HVAC company."

Air Conditioning FAQs, answered by experts

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.

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.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.
