When you invest in a new heating and cooling system for your home, you’re making a big decision. You want a system that keeps your family comfortable through Florida’s hot summers and mild winters. You want reliability. And you want a system that lasts for years without constant repairs.
Here’s something many homeowners don’t realize: the brand you choose is only half the equation. The other half? The contractor who installs it.
Even the best HVAC system can underperform if it’s not installed correctly. Poor installation can lead to higher energy bills, uneven temperatures, frequent breakdowns, and a shorter lifespan for your equipment. That’s why working with a qualified, certified installer is just as important as choosing a quality brand.
Mitsubishi Electric is one of the most innovative and reliable names in heating and cooling. Their ductless mini split systems and heat pumps are known for energy efficiency, quiet operation, and advanced technology. But to get the most out of a Mitsubishi system, you need a contractor who knows these systems inside and out.
That’s where ABS Heating & Air comes in. As a certified Mitsubishi Diamond Dealer serving Ocala, Marion County, and the surrounding areas, we’ve earned the highest level of recognition from Mitsubishi Electric.

In this article, we’ll explain what that means for you and why it matters when you’re choosing an HVAC partner.
Not every HVAC contractor can install Mitsubishi systems. And even among those who can, there are different levels of certification. The Mitsubishi Diamond Contractor program represents the top tier.
Mitsubishi Diamond Dealers are independent contractors who have been specially trained and certified by Mitsubishi Electric. These dealers meet strict standards for technical expertise, customer service, and business practices. They’re not just authorized to install Mitsubishi products. They’re recognized as elite partners who represent the brand at the highest level.
To become a Diamond Dealer, contractors must complete extensive training on Mitsubishi’s product lines. This includes hands-on instruction for installing ductless mini splits, multi-zone systems, heat pumps, and advanced controls. The training covers everything from system design and load calculations to refrigerant handling and troubleshooting.
But certification isn’t a one-time achievement. Mitsubishi requires Diamond Dealers to participate in ongoing training to stay current with new products, technologies, and best practices. This ensures that your installer has the latest knowledge and skills to deliver excellent results.
Diamond Dealers also must maintain high customer satisfaction ratings. Mitsubishi monitors feedback and holds its top dealers accountable for quality workmanship and service. This creates a level of accountability that protects homeowners and ensures a positive experience.

You might wonder why certification is such a big deal. After all, don’t most HVAC contractors know how to install air conditioning systems?
The truth is, ductless mini split systems and heat pumps are different from traditional HVAC equipment. They require specialized knowledge to install correctly. Here’s why working with a certified Mitsubishi Diamond Dealer makes a difference.
One of the most common mistakes in HVAC installation is choosing the wrong size system. If your system is too small, it will struggle to keep your home comfortable. If it’s too large, it will cycle on and off too frequently, wasting energy and causing uneven temperatures.
Mitsubishi Diamond Dealers are trained to perform detailed load calculations. They assess your home’s square footage, insulation levels, window placement, ceiling heights, and other factors. This ensures your system is sized correctly for your specific needs.
In Florida, factors like humidity control and sun exposure are especially important. A Diamond Dealer understands how to account for these regional considerations.
Ductless mini split systems involve precise refrigerant line work, electrical connections, and outdoor unit placement. Even small errors during installation can affect system performance and efficiency.
Diamond Dealers follow Mitsubishi’s installation guidelines to the letter. They know how to position indoor units for optimal airflow, where to place outdoor units to maximize efficiency, and how to ensure refrigerant lines are sealed and insulated properly.
This attention to detail prevents common issues like refrigerant leaks, inadequate cooling, and noisy operation. It also helps your system run more efficiently, which can save you money on energy bills over time.
Mitsubishi provides Diamond Dealers with access to specialized tools, technical support, and resources that aren’t available to non-certified contractors. This includes technical hotlines, product updates, and troubleshooting assistance directly from Mitsubishi engineers.
If a unique challenge comes up during your installation, your Diamond Dealer has the resources to solve it quickly and correctly.
One of the biggest benefits of choosing a Mitsubishi Diamond Dealer is warranty protection. Mitsubishi offers some of the best warranties in the HVAC industry, but to qualify for extended coverage, your system must be installed by a certified contractor.
When you choose ABS Heating & Air for your Mitsubishi installation, you get access to extended warranty options that aren’t available with standard installations. These warranties provide extended coverage for parts, giving you peace of mind and protecting your investment.
Extended warranties can save you thousands of dollars if a component needs repair or replacement. They also demonstrate Mitsubishi’s confidence in both their products and their certified dealers.
It’s important to note that warranties can be voided if your system is installed by an unqualified contractor or if proper installation procedures aren’t followed. By working with a Diamond Dealer, you ensure your warranty remains valid and enforceable.

If you’re considering a new HVAC system, it’s worth understanding why so many Florida homeowners are choosing Mitsubishi ductless mini splits.
Mitsubishi systems use advanced inverter technology to adjust compressor speed based on your cooling or heating needs. This is much more efficient than traditional systems that simply turn on and off. According to the U.S. Department of Energy, ductless mini split systems can reduce energy use by up to 30% compared to conventional HVAC systems. https://www.energy.gov/energysaver/ductless-mini-split-air-conditioners
In Florida, where air conditioning runs much of the year, this efficiency translates to significant savings on your electric bill.
Traditional duct systems can accumulate dust, allergens, and mold over time. Even with regular cleaning, ductwork can circulate contaminants throughout your home.
Ductless systems eliminate this concern. Each indoor unit has its own multi-stage filtration system that reduces dust, bacteria, pollen, and other airborne particles. This is especially beneficial for family members with allergies or respiratory conditions.
With a ductless system, you can create multiple zones in your home. Each zone has its own indoor unit and thermostat, so you can set different temperatures in different rooms.
This is perfect for Florida homes where some rooms get more sun exposure than others or where family members have different comfort preferences. It also means you’re not wasting energy cooling rooms that aren’t being used.
Mitsubishi indoor units operate at sound levels as low as 19 decibels. That’s quieter than a whisper. You’ll enjoy consistent comfort without the noise of a traditional air conditioning system.
Because ductless systems don’t require ductwork, installation is faster and less invasive than traditional HVAC systems. This is especially helpful in older homes, home additions, or spaces where adding ducts isn’t practical.
The cost of a Mitsubishi system depends on factors like the size of your home, the number of zones you need, and the specific equipment you choose. While Diamond Dealers focus on quality over cutting corners, the long-term value often outweighs any initial cost difference.
With proper installation, extended warranties, and energy savings, choosing a Diamond Dealer can actually save you money over the life of your system.
Mitsubishi systems require specialized knowledge and certification. Attempting a DIY installation or hiring an uncertified contractor will void your warranty and could result in poor performance or safety issues.
HVAC work also requires proper licensing and permitting. In Florida, HVAC installations must be performed by licensed contractors to meet building codes and safety standards.
