Norfolk County Heating And Cooling is a leader in providing our customers with the highest quality service in an honest, efficient, and professional way. Our pledge is to create successful relationships with our customers, employees and community by building trust, treating every project with the utmost integrity and exceeding expectations. We look forward to working with you!

"Contractor Recommendation: Norfolk County Heating & Cooling Our 1895 refurbished Victorian's 3rd-floor mini split unit needed repair. Leaking lines were replaced. A chemical reaction between the copper line and wrapped insulation caused pinhole leaks in the line set. Manufacturers recalled that the warranty had expired and the unit was cooling poorly. Four contractors were contacted for estimates. Owner Patrick and project supervisor Renato excelled. They quickly listened and explained the problem, process challenges, and possible solutions. The price given was accurate and a fraction of the others I received. That worried me until it became clear the other contractors had quoted outrageous pricesâ either their company was understaffed and didn't want the small project or thought the customer was ignorant. The other contractors pressured us to upgrade from line replacement to system overhaul. One refused to provide an itemized breakdown of the FIVE times Norfolk H&C estimate but continued contacting me to finalize the sale without changing the price or explanation. Renato visited the day before the appointment to take additional photographs and check his materials. On replacement/installation day, Renato and his assistant were punctual and polite, knocked and asked permission before entering the property, and were great to our small dog. They avoided disturbing a newly planted lawn and cleaned the house and area. Renato showed me the finished project, how he installed it, what he replaced, and its system testing. I highly recommend Norfolk County Heating & Cooling for any HVAC projectâ one of our most remarkable home contracting experiences."

"Young man who came to do the job told us that they sent him to 3 wrong houses before they found ours. He proceeded to unclog the drain in the basement using the mechanical drain. Took him maybe an hour to clear it and also ran our sinks and toilets to make sure we wouldn?t have another problem. The young man left our house, however proceeded to sit in his running van, parked in my parking spot. I had no issues with this service until I saw the bill. $1000 to snake a drain for an hour? When we inquired about the bill they told us that their rate is 300$ an hour and that the job took 3 hours. In my opinion, if it takes you 3 hours to snake a drain, then someone should be fired or retrained at their job. My assumption is that their scheme involved sending this young man to multiple wrong houses and him sitting in my driveway for a prolong period of time, so that they could charge us for 3 hours of ?work.?

FAQs for central a/c installation projects in Waltham, MA

If you’re replacing an old AC system with a new unit, you can usually clean and repair the old ductwork without having to conduct a full replacement. Cleaning HVAC ducts typically costs around $400, while repairs range from $200 to $1,000. In contrast, installing new ductwork can range from $1,000 to $5,000, making it far more costly than cleaning or fixing existing ducts. HVAC installation costs an average of $7,000 to replace a full system, so staying on top of maintenance and repairs is important.

AC cost efficiency depends on the size of your space and your long-term plans for your home. If you only need to cool a small area, a portable AC unit has a low upfront cost. Heat pumps are typically the most cost-effective option if you want to cool an entire home or improve the resale value. They provide strong cooling while being energy-efficient, which saves you money on your utility bills compared to most other AC types.

Installing a central AC unit typically takes four to eight hours if your home already has ductwork in place. However, if new ductwork needs to be installed, this can add another one to two days of labor to your project.
