"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

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.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

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.
