"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!"

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"se  Rob is a dream come true. As a single woman running my own home and being very particular.....it is extremely important to be able to discuss the job, hear all the details, and employ someone who is honest, honorable, well qualified, neat, and highly informed. I first hired Rob for the drain problem. He accomplished that efficiently and neatly at a reasonable price. We discussed options for a back up for the sump pump. Having a finished basement, I am always concerned about water. I have never lost electricity during a rain storm....but the possibility always takes up space in my brain. I have a portable generator....but I have to be home to start it. Today Rob arrived on time and installed the back up for me. It took the whole morning as he predicted. He explained how it all worked and it is a beautiful thing. I so appreciate knowledgable and personable service. I highly recommend Easy Flow Drain and Mechanical LLC for any plumbing needs. Oh....one more thing...he noticed a leak in my fairly new furnace exhaust piping. He pointed it out and gave me several possible reasons for the leak so I could intelligently discuss it with the company that installed the new energy efficient furnace. What else could you want from a plumber? I was extremely satisfied and impressed with his service. I'm also grateful for Angie's List!!!!

"Braido is a nice family run company.  I had the original 25 year old furnace and AC. I has the last house on the block to replace them.  Needed to get it done before winter.  They showed up the day I called for an estimate, took measurements, checked old system and discussed in detail my options for a replacement system.   No pressure to sell me the best as we will down size in a few years. A few days later quotes for two systems arrived. I was able to scheduled an installation that fit my schedule.  It was your typical one day job.  Everything went smoothly with the installation, and the old hardware was taken away.  I like this company and recommend them, I give them and A.

"From the estimate to the final installation you won’t find a more professional company. They installed a new carrier furnace and air conditioner and did an excellent job. I highly recommend them for any of your HVAC needs."

"Keith and his crew are extremely professional and knowledgeable, and did an outstanding job installing a heat pump and brand new ductwork into a difficult old house.

"I needed to install a water powered sump pump. Tom gave an estimate and actually charged me less because the digging didn't take him as much effort as he had estimated. He made sure I got the equipment in order and he returned an earlier delivery since he wasnt satisfied with its float assembly. The job was completed professionally and on time. On top of that he is a very nice person to deal with and fixed a couple of minor issues with my other faucets at no extra cost. Well recommended an I will call him again if I need any plumbing work done."

Install Boiler questions, answered by experts

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

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.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

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.

Costs range from $3,000 to $7,500, depending on system size and efficiency.
