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.

"After interviewing several companies and getting quotes, we were most convinced of the combination of quality and value offered by Mull Brothers. After working with them, we saw that our decision was the right one. They performed all the work very well and in the time frames they had estimated and stayed available for any questions we had after the job was completed. We are very happy with the results and happy that we hired them."

As a child, riding around with my father, he would often point out homes that he had remodeled. It seemed almost every street we turned down had a house with some aspect of it that he had touched. The variety of places he would work and the distances he would travel led me to take up a trade as well. I gravitated toward the remodeling aspect of the electrical trade early on and have built my business on remodels/renovations over the last 18 years. Be it a simple powder room or major department store, I have tackled every size renovation, and for the past 27 years, always taken pride in my work and satisfaction from a job well done.

Heating and Air Conditioning questions, answered by experts

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.
