"They are very professional got the job done. They even did most of the install in the rain and a dark basement while the power was out due to major storms. I would recommend Logan A/C and heat."

"I recently hired Timken for bath/shower, sink, and toilet install I couldn't be happier. The quality of installation was top-notch! Tim proved his great technical experience and the professionalism by taking the time to ensure the functioning and cleaning of job site once finished. Where scheduled to add under sink water softening system too with his reasonable pricing. Highly recommend."

Hi! I am a chemical engineer specializing in industrial utilities by trade who enjoys fixing and building things in my free time. I offer services such as furniture building, home appliance repairs (ovens, refrigerators, freezers, dishwasher, garbage disposal, washer/dryer, water heater, A/C, furnace, sump pump, etc) small scale plumbing or drainage projects/repairs (exterior storm water drainage, pvc/copper piping- I do not do cast iron, faucets, etc). I can install new appliances, but might need help lifting and setting the appliance (I do not dispose of old appliances). I also can repair kitchen stand mixers such as Kitchen aids (rebuild/regrease).

"They are very professional and concerned that their customers are satisfied with their work. I would give them 10 stars if I could. They provide excellent value for your money. They had already completed our job while other companies were just getting around to contacting us! A furnace replacement during the winter is something that must be dealt with immediately, and Universal understood that. I will highly recommend them. A great group of people!"

Water Heaters questions, answered by experts

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.
