"I enthusiastically recommend this company. Mehmet was always prompt for appointments and texted to let you know he was on his way. His crew worked from 7 am to 7 pm and got our new central A/C system installed in one day during a heat wave. Very professional outfit, polite and cheerful to have around."

"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!"

"Excellent! The team worked diligently for 5 days to install a central air system in our old house with Plaster Walls. It was NOT easy, yet they did a fantastic job. They were able to add all ducts to the first floor with out any "chases" or enclosures requiring to be build. And almost none of our first floor lines up with our second floor closets, but they figured it out. Great time and fantastic service. Make sure you get Brandon and Sean. The work their butts off, and ensure your house stays clean (they cleaned up everything after every day - not an easy feat). Cannot say how happy am I with their work!"

"I called All Weather to give me a quote for replacing my gas boiler. They set up a time for their salesperson to come over and give me a quote. The appointment was only a few days later and a man named Joe showed up on time. He spent some time with me, I told him I was looking for a new boiler and a new hot water heater, but I wanted to see what options I have (since I was debating going to a tankless water heater). He told me going indirect hot water tank is the best option and they always use this brand that's the "best one out there". Even though he may have been right, he didn't tend to my questions or concerns very well. I felt like he was getting annoyed that I had questions and eventually I just let him run the show just to get him out of my house faster. Especially when he gave me a quote of $8600, it was much higher than I was anticipating. One thing I really didn't like was when he said I'd have to get a permit since I live in an incorporated village, which would be an extra $500, meanwhile I already had another plumber tell me a permits only $200. So I went with another company. So even though I can't rate All Weather on their work quality, I didn't get a good feeling from their salesperson."

"Mo was a very able, responsive and professional technician who installed our furnace in one day and our new boiler two days later. He patiently answered my many questions, walked me through why we needed two new units (instead of repairing our old ones) and worked well and efficiently. It was painful to have to pay that much money at once for a furnace and a boiler, but Mo made it as positive an experience as it could have been. I am grateful to him and his assistant for their work and professionalism."

"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."

"Angelo was very thorough and answered all my questions. He got my heat back up and running quickly. Even after the job was finished he came back promptly to address a boiler issue I had unrelated to his work. Highly recommended."

Install Boiler questions, answered by experts

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

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.

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.

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.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.
