"Daniel from Imperial Electric did an excellent job for us. We had a relatively small issue that he rectified for us very quickly and then did a very thorough inspection of our entire house at our request. He made a number of recommendations to upgrade our old electrical system that were practical, reasonable and in line with current codes."

Heating and Air Conditioning questions, answered by experts

In some cases, yes, portable air conditioners are worth buying. They’re a relatively affordable option for cooling small spaces. (On average, they cost between $100 and $500 per unit.) Plus, they’re easy to set up, and you can move them around to cool various parts of your home as needed. However, they aren’t the most efficient AC option, and they tend to be noisy.

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

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. 

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

If you’re looking for an energy-efficient heating and cooling system to heat a compact to average-sized home, then a ductless system is absolutely worth considering. The installation is less hassle when compared to a ducted heat pump system, and because your electricity bills should drop, it’s an excellent long-term investment.
