We're dedicated to providing our clients with the very best in service, installation, and repair for your heating and cooling needs. We are a locally owned and operated company that values honesty and integrity. We specialize in central A/C and cooling systems, as well as heating and furnace systems. We take pride in the quality of our work, and our commitment to outstanding results. We look forward to building long-term relationships with our clients, and guarantee your satisfaction! Visit us @ RJKMECH.com

"Short version: Professionalism, competency, and integrity is what you can expect from RJK. When our AC stopped working, another company came out to investigate and we were quoted an outrageous temporary repair cost and were advised to replace the whole system. We called RJK and they called back almost immediately. Upon arriving, they advised that a whole system replacement would be unnecessary for starters. But before even doing that, they wanted to have their techs double check that the system was truly in need of any replacement. Turns out the fix was straightforward and within 30 minutes the system was repaired at a fraction of the cost of the original contractor's quoted repair cost and definitely cheaper than a whole new system."

Lamco Plumbing & Heating Contractors, Inc., has been in business since 1975. We do all aspects of plumbing , and heating repairs service and installation. We specialize in boiler Installations and oil to gas conversions.

"Most recently we had the pleasure of working with Tom and Anthony from the LAMCO team installing a new gas steam boiler. Process was seamless, in fact, replacement was done in 1 day during heating season! Materials, workmanship and quality were excellent. From start to finish, their communication was excellent, keeping me informed every step of the way. The team demonstrated unmatched expertise and professionalism throughout the project, answering all my questions and ensuring everything was done to the highest standard. I highly recommend LAMCO to anyone considering similar projects. LAMCO has done several projects for our historic home-new kitchen, updated bathrooms, fireplace gas insert, without any hitches. Exceptional service all around! Each of our projects were completed on time without any technical, financial or administrative deficiencies. All projects were reviewed and approved by inspectors. LAMCO also qualifies for the NJ GAS Boiler Efficient Loan program. "

Winner of the 2020 Angie's List Super Service Award, a winner nine out of the past 10 years. We are a locally owned family business supported by a national franchise company which is North America's most trusted handyman company. For more than 15 years we've consistently hired experienced, reliable craftsmen​ (not sub-contractors) who are licensed, insured, bonded and background checked. That means you'll receive consistently high quality work that is 100% guaranteed. What sets us apart​: Mr. Handyman's professionals arrive in branded uniforms and vans that are stocked with every tool they'll need for your job. Our on-time record is second to none, and we arrive ready to work. One phone call to Mr. Handyman hires professionals who complete your entire "To Do" list. Every task whether major or minor home repair is prioritized according to your needs. Rather than calling a specialist for drywall repair and another contractor for rain gutter repair, your neighbors consistently choose us for all their home improvement needs. Mr. Handyman can complete a variety of projects for you, from installing doors, to tiling your bathroom, repairing your deck and much more.

"Had to reschedule my original appointment due to their late arrival for the first scheduled time. The office admin was helpful in taking care of that. Once they did arrive on a later date, the work was done quickly, efficiently and of high-quality. I will consider them for an additional project in the future."

Heating Oil questions, answered by experts

Costs depend on system age, type, labor, and whether part replacements are necessary.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.
