Avoid a Costly Breakdown of Your Comfort System

Approximately 80% of the emergency calls PROTECH HVAC, LLC receives stem from problems that could have been identified during a preventative HVAC maintenance check. Avoid an emergency during extreme temperatures by scheduling a maintenance visit with us. We provide a range of plans tailored to your needs!

Service Contract Option

Invest in preventative maintenance plus extra perks with our service contract option! If you’ve got an older comfort system, a service contract is a wise choice that can significantly reduce expenses on expensive repairs and future replacements.

Mitsubishi Electric Ductless Preventative Maintenance

Mitsubishi Electric Ductless Maintenance: $125 Per Hour, Per Indoor Unit


Preventative maintenance is 100% necessary for your ductless mini split system to maintain optimal comfort, drive energy efficiency through the heating months, and protect your HVAC investment.


Due to the compact, efficient size of these units, additional time, tools, and attention are required to clean them properly. That's why we charge by the hour for their preventative maintenance. It typically takes 45 minutes to an hour to clean each unit, but the time can vary depending on the level of cleaning required. Our rate is $125 per hour, per indoor unit.

I wanted to install a mini-split ductless air conditioner by myself, but after getting midway through it I discovered that the installation would require (by law) an HVAC professional, and an electrician to run power from my panel to the outdoor unit. I called PROTECH and they agreed to do the job the very next day. They offered a very fair price, had excellent communication, and were in and out in only a few hours. The technicians were very professional and polite, and got the job done in excellent condition. I could not have asked for more! I would hire this company again for any job!
