"I Called to get an in person quote for a tankless water heater flush and left this job with a whole house filter and a fridge connection. When Michael first arrived we inspected the tankless unit and tested the water to conclude flushing was not my best option. He then walked me through my options for home filters and we decided on a Halo system. Michael was very well educated on the subject and gave me the best value filter for my needs. He installed the unit the next day in less than a few hours and left me with a flawless work of art. I couldn't be more impressed with the professionalism he brings to this trade! I also requested to hook up a fridge and he did that in what seemed like 30 minutes. He will be the only plumber I call from now on!! Thank you Michael!!!"

"West Tech Mechanical Services (Joe Gonsalez) did an excellent job. This is the best investment that I have ever made for our quality of life in our home. Joe's attention to detail is evident in the care and consideration that he put into the duct work in the installation process. He thoroughly explained to me the importance of the duct work: location and size of the ducts to maximize the efficiency of the system that he was installing. Our home is an old home, and I really appreciate the care that he took in the installation process. I obtained 3 quotes for this job and West Tech Mechanical was in the middle. All the persons that came to our house were nice people. However, Joe's obvious attention to detail and how he explained the job is what convinced me that he and his company were the right people for the job. For a home owner that is considering the installation of a central air and heat system in their home or, any work for that matter on an existing heat and air system, I highly recommend this company as one that should be considered."

Install Boiler questions, answered by experts

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).
