My name is Tom Mull of Mull Bros. Oil, a family-owned heating and cooling company in Wethersfield, Connecticut, where I was born and raised. There’s no doubt that you have seen many changes with the heating oil industry in the past decade or so. While many companies have given up or, out of desperation, have changed their business philosophies, we intend to be here for a long time. As a matter of fact, we’ve been around for over 60 years. My father, Bill Mull, started this company in 1945. At a time when stove-oil was in great demand and #2 fuel was being introduced as a home-heating fuel, Bill decided to get in to the delivery business. In the early 1950’s many oil burners were being installed on coal furnaces. Being mechanically inclined, Bill learned the art of installing and servicing the many styles of oil burners and heating systems.

"Said I was too far for a smaller job, and rather than try take advantage was genuine and honest and provided many good tips. Extremely nice and helpful --- just too bad there not in the neighborhood"

Window a/c unit installations FAQs

Running a window air conditioner to cool a small room often costs less than $4 per day, making it cheaper than central air for single-room cooling. However, central air might be more efficient if you're using multiple window units or need to cool a space larger than 1,000 square feet. Choosing the right size AC is crucial—a unit that's too big or small can waste energy and increase costs.

Window AC units can use a significant amount of energy. These units use about 12 to 17 kilowatt-hours per day, significantly more than a refrigerator's one to 1.5 kilowatt-hours per day. To keep your energy costs down, run your window AC only when necessary, keep doors closed to contain the cool air, regularly clean filters and coils, and seal any gaps around the unit to prevent cold air from escaping.

Inexpensive air conditioner units are often not worth it. Low-cost products from popular brands like General Electric, LG, Whirlpool, or Frigidaire may be a reasonable investment. However, putting a small, budget-friendly unit in a large room wastes energy and shortens the life span of the AC since it has to draw more power and work much harder to cool the space. The unit will consume more energy and stress the motor and other internal parts, resulting in early breakdown and costly repairs.

The best deals on window AC units come during the fall when businesses slash prices to clear out old inventory. You can also speak with your local AC installer, who may get you a good deal on a window AC unit since they have access to trade pricing. You can also watch for discontinued products and flash sales in your area.

Window AC repair costs between $110 and $390, with most people paying around $250. Parts cost between $2 and $150, with the rest going toward labor, at around $30 per hour. The occasional one-off repair or a routine AC tuneup cost $75 to $200. Servicing can keep your AC running in good condition for several more years before you need to pay for a replacement unit.

Window AC units last eight to 10 years when installed and maintained correctly. High-quality models last up to 20 years with proper care and routine maintenance. The unit’s longevity depends on its construction quality, regular cleaning, and electrical safety inspections. Keeping the filters and coils clean and addressing minor repairs promptly extends its effective performance and ensures reliable cooling.
