Types Of Air Conditioning Replacement We Offer

Central Air Unit Replacement

Air Conditioner Upgrades

MJK Mechanical can also help fit your home from one solution to the other. Ductless, mini splits are becoming more and more popular and are sometimes a better fit for the space than a central air system.

When to Consider AC Replacement

  • Unit Age Over 10 Years: If your air conditioner has surpassed the decade mark, it might be nearing the end of its efficient lifespan. The advancements in AC technology over the years have led to significantly more efficient and environmentally-friendly units. Opting for an AC replacement allows you to embrace the latest innovations that promise improved performance and reduced energy consumption.

  • Escalating Monthly Electric Bills: If your energy bills are soaring, it might be attributed to an outdated and inefficient AC unit. Modern AC systems boast remarkable advancements in energy efficiency that can considerably lower your monthly electric expenses. By upgrading to a new model, you not only enhance your comfort but also enjoy substantial savings in the long run.

The Efficiency Advantage of Modern AC Units

 Today’s AC units have undergone transformative improvements in efficiency, noise reduction, and cooling capabilities. By replacing your outdated unit, you’re investing in a system that aligns with modern energy standards and provides a marked reduction in energy consumption. The result is not only a more comfortable indoor environment but also a financially advantageous decision that pays off through lower utility bills.

Many thanks to Jason and his MJK team for their great service! MJK came highly recommended from a trusted contractor, and we couldn't be happier with their service. After an emergency call, Jason was on site within 24 hours and had our air conditioning back up and running in no time after an electrical issue. Jason was incredibly knowledgeable, despite never working on our units, and we appreciated his patience in explaining with great detail exactly what went wrong and his plan to fix it. Professional, honest, and left the job site in pristine condition after getting our units fired back up. Sincerely looking forward to working with Jason and the MJK team in the future as our trusted HVAC contractor.

Had some issues with my AC condenser recently and called a few contractors. By far the most responsive was MJK Mechanical. Even better, when they arrived they were professional, courteous and quick! AC was up and humming in no time for a very fair price as well. Great people to work with and would recommend them to anyone.
