6k+ I had an incredibly disappointing experience with City Plumbing and HVAC. They charged us $600 and did virtually nothing to address our boiler issue. Despite having photos, videos, and opinions from two other plumbers confirming the leak, the tech refused to act because the leak wasn’t...
Zahler is my go-to for boiler service. Very helpful and never try to sell me on work I don't need. I've hired them several times, most recently when the boiler stopped working this spring. They came out the next day, found the problem very quickly, explained perfectly, and fixed the problem.
A different company told me my boiler needed to be replaced and would cost 8-9 thousand dollars. Leon cleaned my boiler and replaced the duct work. He saved my about $7500 dollars! I am very satisfied and would recommend him to anyone. He is a true professional.
Excellent Service! Von squeezed me in to his full schedule in the evening at the request of another technician who was not able to complete the needed repair. He arrived promptly, was courteous and easy to work with and he stayed until all my concerns were completely addressed even though...
I purchased a GE double-oven, glass top stove from Lowe's with a extended service warranty. Last May, I was trying to cook with two burners and it took about an hour to bring both burners to a boil. They send someone out and they said the plug wasn't in all the way. The stove was...
We used Metro Heating and Cooling for our annual boiler and AC maintenance for over three years. Their repairmen were always prompt and professional, but unfortunately we learned after the fact that they were not completing the work they were hired to do. We had our boiler serviced in...

"We had S&J install a new mini-split ductless system on a floor that we couldn't get cool. We also had them analyze our current system in our townhouse, which required an upgraded cold air return duct due to a bad design by the builders. Mitch was our representative, and he did a fantastic job analyzing what we needed. Mitch provided a better, more effective solution than we had heard from any of the other vendors. Additionally, he got us a great price (after rebates) on a system that was better than the other systems we had been previously quoted. The mini-split installation was a challenge, but the installers did a great job. They took their time to create an installation that looks and operates great! The cold air return duct upgrade brought our system static pressure from 0.75 inH2O down to 0.5 inH2O total, which is nearly perfect. Our air handler is running quieter now, and we are getting more airflow through our system. I would give Sanders & Johnson 10 stars if I could!"

"Had maintenance contract with Absolute to service HVAC, electrical, plumbing twice a year. On recent maintenance visit A/C condensation line was found to be clogged due to "dirt getting into the system from lack of filter maintenance". Cost $329 to clean line which was not covered under contract (and seems a bit excessive!!). Was told filter replacement was not covered in maintenance contract. Seems to me that this would be a priority maintenance item! Technician comment on last visit 5 months earlier stated filter was "still clean" and not replaced. Needless to say we will be finding another company to do our maintenance from now on."

Family owned & operated for over 35 yrs. Honest & reliable heating and A/C which includes repair and service of all brand furnaces, boilers and A/C. New installation of furnaces, boilers & A/C. Humidifiers, water heaters, air cleaners and misc. plumbing issues. Install new gas lines for adding stoves, driers etc.; New construction
"Viking had serviced my furnaces and air conditioners in the past. Price was a little high but work was satisfactory. This year, I called four times and used their web site over a six week period to try to schedule a service appointment for the air conditioners. Although I was always told their scheduler would get back to me they never did. A big waste of my time and past money trying to establish a service relationship I could count on. I gave them a "D": rather than an "F" as their call service at least answered all though that was it."

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
