"-- they did not try to overcharge me like several other contractors I consulted with - It went very well - the service was performed in timely manner - the owner Ali and crew were polite and responsive to all needs and knowledgeable of the installation of the work. I had great difficulty finding a contractor who would give me an honest price and who could get it done in time - Highly recommend

"We had an older Heatmaker combination unit boiler that was 32 years old that needed to be replaced. We started out with several estimates and first decided what could be used in our space constrained garage. We decided on a Navien combination unit and focused a obtained a couple more estimates. Dawson in fact was one of the last estimates we obtained. While Dave from Dawson had the benefit of us being well along the learning curve, he was able to answer all of our questions about the new unit and how best to solve the condensate dilemma. He even was spot on with regards to treating our well water to minimize scale buildup in our new boiler. We knew we had reached that point where we felt we had found the best installer in Dave. Dave verified his condensate solution with the local township inspector and we scheduled the install date in two weeks. Carlos and Pablo showed up on time and dismantled the old unit and piping and did a first rate and well thought out installation job. Carlos had extensive experience installing these Navien units and it really showed. They managed to work in a tight space that PSE&G’s installers would not have with relocating a well tank. After all the plumbing was done, Ricky did the electrical work and adjusted some final dip switch settings before firing up the new boiler. Dave and his crew really are top notch. His front office staff (Wanda and Ondrea) made the PSE&G interest free financing and permitting approval process seemless. We are looking forward to the operation and efficiency of our new high efficiency boiler for years to come. If you are installing a Navien high efficiency combo unit, we highly recommend using Dawson Mechanical!"

"They installed central air conditioning in our house. They gave us the best price for what we wanted. Their installing technicians were extremely careful, clean, helpful and quiet. They installed a whole house  (2 floors) system with 12 registers in 3 days. The air handler was installed in the attic and compressor was installed outside. I would recommend them to my best friend and I would use them again if I move to another house."

"the process was better than I expected. The sale man knew what he was talking about . The installation crew had worked for the company a long time and were also very knowable . When we could not understand a few things they sent out a serviceman just to show us how it works. They also directed us towards financiers and reabate availability."

"I used them to install a gas line and hook up a new gas stove. Vince was through and very knowledgeable of what needed to be done. The price was exactly what he quoted, the pipe install was very neat and clean and he connected the stove, tested to make sure everything was working as well as check all the existing gas appliances to make sure they were working after turning the gas back on. I will be using Vince going forward for all of my plumbing needs!"

"Great Experience with Kevin guiding us with the proposal of a Central Air and Furnace replacement. Very professional and answered all questions timely. No hard sell at all. We did have an existing Lennox AC. The install team of Shakil, Ty and Brandon were just as professional. True to their proposal, they came in and installed both systems in one day. Left the area neat and clean."

"Received call from Melissa, who was friendly and professional. Plumber George arrived promptly. He was able to quickly diagnose and resolve a frozen pipe on my heater system, preventing a potential rupture that would have been aggravating and expensive! Very friendly and professional service from start to finish."

Install Boiler questions, answered by experts

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.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

Costs depend on unit size, labor, fuel type, and whether additional piping or venting is needed.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.
