Quality HVAC Services are a Mere Phone Call or Email Away!  

The HVAC contractors provided by MJK Mechanical HVAC are what can be described as the “best of the best.” Whether seeking an installation of a new HVAC system or repair or maintenance of an older system, the prices are right, and the service exemplary. Also, every contractor is certified in the latest methods of HVAC technologies and installations, plus ways of spotting problems before they can start.

There is no uncertainty when hiring MJK Mechanical to service any model or style of HVAC unit. 

We have worked on everything from large chillers in industrial pharmaceutical settings to boilers, condensing units, heat pumps, furnaces, air handlers etc. In such a competitive field and so many under skilled HVAC companies don’t chance your investment to an under skilled company. Let our experienced and trained techs service and install your system the right way. The alternative could lead to a failure. The failure of any unit can be a real monetary loss and a possible safety hazard. It has been shown that too many fires each year have been caused by faulty HVAC units. Units become older with time, and small problems go undetected, unfortunately.

The uncertainty listed above is the root cause of problems with units, as most individuals have no clue about HVAC or what standards must be met. Many times, they might have tried other services and been disappointed. MJK Mechanical wants our clients to get over their hesitancy about hiring someone to service or install their units, and MJK Mechanical seeks to do this by winning the trust of each client we have the pleasure to service!

Proper installation, maintenance, and repair of all HVAC units are crucial for safety and efficiency. 

All HVAC units must run properly to meet safety standards and maintain the highest heating and air conditioning efficiencies. Proper installation and system sizing is a start, but routine maintenance also comes into play to detect small problems before they become significant issues. Although it is easy to overlook small issues, there is no guarantee that a small issue will not blossom into a massive issue in the blink of an eye. MJK Mechanical is on hand for the major problems but does promote units’ maintenance to save their client’s money and time lost with unit failures.

Not all HVAC companies or heating unit installers are created equally.  

MJK prides itself on its work, not just on providing heating units that hum with quality efficiency but also air conditioning unit installations and ac repairs. Nothing is worse than an HVAC unit that fails to heat during a brutal cold snap or an AC unit that fails to cool during a blazing heatwave. These failures are not just mere inconveniences but can lead to loss of equipment and even employees’ illness. 

Avoiding the issues of HVAC unit failures should always be a priority for every company.

There can be general contractors or handymen that claim knowledge of HVAC.

However, some qualifications should remain a priority, and MJK Mechanical provides these: 

  • 24 hour a day service on all service calls, no questions asked! This is truly 24-7, and no call goes unanswered!
  • The best training in the latest technology of all technicians and services. 
  • Training is constant at MJK Mechanical.
  • All calls are answered in 24 hours. No exceptions.  
  • Affordable rates are astounding for the types of service provided.
  • NO hidden charges ever. NO fine print.  What MJK quotes is the price each time!  Our honesty is one of our greatest accomplishments.  We take pride in that and always will ensure that each quote is thorough and complete. 
  • Satisfaction of course is always guaranteed.   No ifs, ands, or buts. Our reviews tell you everything you need to know to be confident in hiring MJK Mechanical. We will always seek 100 percent satisfaction of any clients.

Do not also forget that although winter is upon us now, AC season is around the corner!

Of course, a great reason to use MJK Mechanical now is that we are fully insured and licensed, but also now offer VIRTUAL ESTIMATES! That is correct.  Contact us with any problem, and we can discuss it virtually before we even start work.  

Our team is so well versed in all the latest techniques and methodologies and has so many years of experience under our belt that we do offer virtual estimates now. Many individuals are working remotely from home currently and time is so limited for taking care of necessary chores that our virtual consultations can save a lot of time and energy. We still will stand by our commitment of no added charges. We want our clients to feel as confident in our abilities to fulfill all their HVAC needs as we are. Whether it is a heating problem, or simple tune up that is needed, a full installation of a combination heating and AC unit, MJK Mechanical is here to make the experience a great one.
