"Went great. Maddie H. came by and found the problem with my old water heater. She setup the install for me. Bradley K. installed the new water heater the next day and did an excellent job. Both individuals were very knowledgeable and a pleasure to work with. Great job to everyone concerned. Thanks!"

"Tim did an excellent job installing two new pendant lights in our kitchen. He kept necessary drywall cuts to a minimum, and even cleaned up the drywall dust afterward. The end result was exactly what we wanted, at a very fair price."

"I feel Commonwealth Contracting is very easy to work with. Mike Eippert always responds to any questions we may have had during the process of the work. This is the second major renovation we have had done with "Commonwealth" and both times we were very happy with the results. I will say you need to be patient with how long the project may take. We realized all of these contractors are extremely very busy at this time. However, quality was much more important to me than speed, and all of the work we had done is outstanding. As far as price they are not the cheapest nor the most expensive, however, I feel comfortable that what we paid for the complete renovation was very fair. To me "Quality" of work done is most important and that is what "Commonwealth" provides."

"Excellent! This is our 2nd home renovation and remodel with Double Tap HVAC and Electrical. Our first home we utilized Double Tap to ensure the sale of our home by renovating and updating 2 full baths, and all repairs listed per the inspection report. With Double Tap being a licensed contractor, electrician and HVAC it was a total win versus using several companies to complete the job! Outstanding work ethic, affordable pricing, impeccable knowledge base, and consistent daily work to get the job completed on time! We used Double Tap again for our newly purchased home to renovate our entire living space to create an open floor plan. This entailed wall removal, beam / support installation, mold removal, subfloor leveling, attic/ crawl space inspection, floor installation, and a complete staircase reconstruction. Double Tap has also made after hours HVAC emergency service calls for us. I highly recommend Double Tap HVAC and Electrical and will always be a loyal customer recommending to anyone that owns a home or business!"

"From the start Mike was very professional and pleasant when he came to give us an estimate for painting the outside soffit around the whole house outside, porch railings, pickets and stairs. When we decided to have him do the job, as his price was reasonable for the work wanted, we called and he stated he would send a contract and have the work done by 10-30-14, which was 2 weeks away and would take 1 1/2 days to complete. He called on 10-21-14 and stated he would be at the house on 10-23-14. All the work was done and it looks terrific. There was no mess to clean up, they did it all.  We are very happy with his work and would highly recommend him and have him do any future painting needed at our home.

Install Boiler FAQs, answered by experts

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

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.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.
