"I had an ancient gravity fed gas boiler that was way overdue for replacement. I also had a separate gas water heater that was getting older. Tom Mull, the owner, came by and proposed a solution to replace both at a reasonable price.
The crew that installed the system was very professional. They showed up when they said they would and finished in the timeframe promised. They also left my basement broom clean.
I would highly recommend you consider using Mull Brothers.

"Danny, from HL Bowman, quickly understood the scope of the installation and used his expertise to make the installation seamless. As a result, the filtration system he installed is now operating perfectly to remove particulates greater the 5 microns from our well water. I would highly recommend HL Bowman for your plumbing needs. "

"Joe and his crew did an excellent job installing new boiler and indirect hot water system. I made the decision to convert to gas and replace my 21 year old oil fired boiler. Everything went along smoothly and professionally. Joe kept me informed every step of the process and job was completed on time. I would definitely recommend."

"Bruce really listened to how I answered his questions and designed a natural-gas fueled steam boiler system that met all the requirements with the expansion potential I requested. During pre-installation logistics and the day of installation, Bruce and his crew were on-time, courteous and professional. Their work demonstrated the benefits of hiring a fully credentialed company, skilled and experienced at their craft. They completed their work in one very long day so that I could avoid a night without heat during a stretch of very cold January days. I trust Williams & Assoc. and would hire them for additional work in my home as needed"

"Perfect as I expected and more. East Coast installed a central air system and a ductless heating and calling system in my house. They were much affordable than their competitor."

"We originally contacted Brian to measure, source and install window treatments on some skylights and windows, and when we found out he's a renaissance man, we asked him to do many other jobs for us as well--carpentry, electric, plumbing, labor & assembly, you name it. He's a consummate professional, easy to communicate with, and a pleasure to work with. He's such a nice guy I even invited him to stay for dinner one evening after he finished working. I'm not sure at this point what Brian can't do, but I'd trust him to tell me if something I asked for was beyond his wide ranging capabilities. We will absolutely hire Brian again and again and continue to refer him to friends in the future. The only challenge is that his schedule books up since he's highly in demand, so contact him sooner rather than later.
Some of Brian's work for us has included:
- Repair of a slatted blind that Brian told us didn't really need replacing after all
- - Full-service window treatments for skylights and windows--we love them, and Brian's advice was helpful
- Selection and installation of a new blind to match others next to it--looks great
- Installation and assembly of 2 ceiling light fixtures. We didn't have the right part for hanging one from a vaulted ceiling, and Brian made sure to get one for us that fit the aesthetic perfectly. No corner cutting.
- Hanging pictures and heavy shelves
- Plumbing help with 2 leaky refrigerators
- Disassembly, strongman labor, and reassembly of a large piece of exercise equipment in another room in the house
- Window replacement
- Installation of a cat door through a sheetrock wall
- Installation of a track for a pocket door
- Installation of dimmer switches
- Assembly and installation of a large closet system
...etc. We've been happy with the results of all these projects--and all the rest that I can't remember at the moment.

Converting from an oil furnace to an electric furnace isn't a simple swap—the oil system needs to be completely removed before installing the electric furnace. You'll need a full electric system installation, but you might be able to reuse existing ductwork if it's up to current safety standards. You’ll need to budget for a new electric furnace installation, which costs between $1,800 and $6,200, including professional removal, proper disposal, and safe installation of the new system.
Electric furnaces are 100% efficient at converting electricity into heat. However, some of that heat can be lost as it travels through your home's ductwork or escapes through poorly insulated areas. That's why regular duct maintenance and proper home insulation are important to maximize your furnace's efficiency and reduce heat loss, ensuring consistent warmth and lower energy costs.
With proper maintenance, an electric furnace can last anywhere from 20 to 30 years, outlasting the average gas furnace's lifespan of 15 to 20 years. To keep your electric furnace running efficiently, schedule regular cleanings, tighten connections, and have inspections done before winter arrives. With routine maintenance, you’ll ensure consistent, safe heating for years to come.
The size of the electric furnace you need depends on factors like your home's square footage, climate, and insulation quality. As a general guideline, those who live in warmer climates should multiply their square footage by 30 to 35 BTUs, while those in cooler areas should multiply it by 50 to 60 BTUs.
Consulting with an HVAC professional can help you determine the exact size that's right for your home.
An electric furnace works by converting electricity into heat using high-resistance heating elements. A blower then pushes the warm air through your home's ductwork, distributing heat evenly throughout your space. Since there's no combustion involved, electric furnaces eliminate the risks associated with gas furnaces and provide consistent, reliable heating when properly installed.
An electric furnace uses between 40 and 80 kilowatts per day to heat your home. The exact amount it uses depends on factors like your home's size, insulation, and overall energy requirements. Larger homes or those with poor insulation use more energy than smaller, well-insulated spaces. A professional furnace assessment can help confirm the ideal unit size for your needs.
