Is Your Home Ready for a Mini Duct HVAC System?

Closeup of Smaller Duct Lines

Traditional Vents are Much Larger Than Those in a High Velocity Mini Duct System.

While the concept of high velocity AC has been around since the 70’s, these symptoms have soared in popularity in recent years. Not only do homeowners use high velocity (also known as mini duct HVAC) systems to retrofit their aging duct work, many new construction properties utilize them as well. While these premium systems may cost more at installation, they offer several opportunities to save money with improved efficiency and functionality. Here’s how!

What is a Mini Duct HVAC System?

High velocity HVAC systems utilize a specialized pressure system to force air through a serious of flexible duct work. The ducts are comprised of very small tubes (some are only 2 inches wide), which can fit behind traditional wall spaces and effortlessly curve in and out of tight spaces. Smaller tubing provides several helpful benefits for homeowners, which we will talk about in a little bit.

Traditional HVAC Solutions

Traditional forced air systems operate at a much slower pace, taking additional time to circulate air throughout large houses. Their rigid ducts require a lot of space to install, making additions to an original forced air system could require you to tear up ceiling areas just to make room. Diverting to newly added rooms is just as frustrating.

The duct work in forced air systems is susceptible to wasteful leaks that develop over time. While they may go unnoticed for months or even years, these leaks will cause your HVAC system to activate for longer cycles. This not only increases energy consumption, it also accelerates wear and tear on your HVAC unit’s mechanical parts. When compared with traditional air conditioning systems, high velocity AC is clearly the winner in terms of functionality and efficiency.

High Velocity Air Conditioning Pros and Cons

High Velocity Mini Duct System

In a High Velocity Mini Duct System, Duct Lines are Considerable Smaller and Better Insulated.

There are several alluring perks for installing a high velocity HVAC system. Compared with other solutions on the market (even mini split systems) high velocity air conditioning is incredibly convenient and space saving. As we mentioned earlier, these systems can supply heating and cooling much faster than forced air systems. As a result, your home’s air is conditioned in less time and your HVAC system can turn off sooner, saving energy.



  • Little to No Construction Work Needed During Installations
  • Simple to Use During Retrofits or Extensions
  • Requires About 1/3 the Space of Traditional Ducts
  • Circulate Air Faster For Speedier Heating and Cooling
  • Shorter Run Times, Saving Energy
  • Tubing Can Fit Behind Walls and Between Rafters
  • Little Equipment Needed to Serve a Full House
  • Vents are Less Noticeable in Ceiling


  • Cost of a High Velocity Mini-Duct System Somewhat Higher
  • More Complicated to Adapt for Zoned HVAC
  • Rush of High Velocity Air Can Be Chilly

High Velocity Air Conditioning vs Mini Split

As you can see, there are numerous benefits provided by high velocity systems. But how do they stack up against a more premium solution, such as a mini split HVAC system? Let’s compare the two!

Mini Split Systems Explained

Mini Split Systems are More Obvious, But They Can Customize Room Temperatures.

First, we need to understand the core function of a mini split solution. Also known as “ductless split systems”, mini splits utilize up to 4 ceiling or wall-mounted units which are connected to an outside unit by a single tube. The indoor units take in warm air from each room, flush the heat outside, and redistribute the now-cooled air. One of the primary reasons homeowners love mini splits is that they can customize the temperature in each room with an indoor unit. Plus there is practically zero duct work required to install the system.

Now how does this stack up with high velocity AC?

The Two HVAC Systems Compared

We’ll break down different aspects of each system and declare a winner in each category. Let’s start with space requirements.

  • Hardware Requirements: Tied

While mini split systems require no duct work to circulate air, most are limited to cooling 4 rooms. To provide customizable temperatures for more rooms, a second air handler will be required. On the other hand, a high velocity HVAC system requires a little duct work, but it also heats and cools the entire house with just one unit. Both provide an impressively small HVAC system. Thus, we come to a tie. 

  • Efficiency: High Velocity Mini Ducts

The pressure-powered system of a high velocity AC speeds air throughout the house at an impressive rate, considerably faster than mini split systems. High velocity wins. 

  • Customization: Mini Split Systems

While high velocity systems can be augmented to achieve zone control, mini split systems have this feature built into their basic design. Mini split wins.

  • Appearance: High Velocity Mini Ducts

The temperature customization of mini split systems comes with a notable downside: protruding boxes mounted on the wall. Mini ducts feature tiny, powerful vents that function well but aren’t as noticeable. High velocity AC wins. 

  • Cost: Tied

Do expensive roof leak repair costs have you looking for the most affordable HVAC system option? The cost of a high velocity mini-duct system is very close to that of a mini split system. If a home requires more than one air handler however, the mini split system may cost more. It’s close though, so we’ll call it a tie anyway.

Common Problems With Home Air Ducts

Air Ducts

Leaky Ducts Can Cost You Hundreds in Higher Energy Costs. Keep Them Sealed as Best You Can!

Your HVAC system daily relies on healthy air ducts to efficiently transport cool air around the house. Unfortunately, air ducts come with their fair share of problems, which can be surprisingly expensive to fix (if not detected early on). These problems include:

  • Air Leaks
  • Insufficient Insulation
  • Mold Growth

Today, we have a short guide to help you get a leg up on your air duct maintenance and prevent these nasty hazards! 

How Do You Fix Leaky Ducts?

When you (or your local HVAC technician) gets to work fixing your air ducts, the first thing to look out for is obvious gaps and tears in the piping. Generally, large traditional duct work is highly susceptible to cracking and tears after so many years. You home may have significant leaks already; many homeowners don’t know there’s something wrong until their energy bill skyrockets.

As tedious as this may be, you need to seal the cracks as completely as possible. You can take time to add extra insulation while you’re at it, as this almost always pays itself off in reduced cooling costs. If you can’t stand the heat, you can always hire a professional.

How Do I Prevent Mold in My Air Conditioner?

Mold is created when you have too much humidity in your home. Unfortunately, this is a serious problem for many homeowners in Florida, where humidity is just another part of life. There are a number of steps you can take to prevent the growth of mold and mildew, including…

  • Increasing ventilation in your attic (an area often untreated by AC)
  • Installing a UV light filter
  • Installing a whole home dehumidifier

Many local homeowners favor dehumidifiers, since reduced humidity naturally makes the air feel coolerIf you’re having problems removing excess humidity from your home, consider installing a whole home dehumidifier (preferably before you have to call for mold and mildew restoration).

Our Team Can Render Comprehensively Excellent Air Conditioning Maintenance.

Air conditioning maintenance is an invaluable procedure that can lengthen the life of your system. The average air conditioner will last for 10 to 15 years. To achieve the upper end of this estimate, you absolutely need the benefit of regular AC maintenance. Since it lengthens the life of your unit, maintenance will also increase the overall value of your HVAC investment. Units that receive regular care will also require less energy to operate. As air conditioners age, parts will begin to wear out.

As a consequence, your unit will require more energy to adequately cool your home. Expert-level service can reverse this trend, maintain your unit’s optimal level of service, and lower your monthly energy bills. To learn more about the benefits of regular service, give us a call today at 833-321-5665. Kool My Air, Inc. represents your local leader for air conditioning maintenance in Miami Beach, FL.

What Is Involved in HVAC Maintenance?

Astute AC maintenance will cover five different areas. Each of these has a vital impact on your air conditioner’s functional capabilities.

Refrigerant Levels: Your air conditioner uses refrigerant to create cool air. Over time, your refrigerant levels may drop, due to leaks or other problems. An AC with low refrigerant will work harder to regulate your home’s temperature, and can eventually lose its ability to create any cool air at all.

Electronic Controls and Components: Maintenance should comprehensively check your ACs electrical connections and components. Problems here can short out your system, and render damage to other interior parts.

Air Conditioning Maintenance

Maintenance Allows Us to Perform Preventative Repairs to Save You Money.

Parts Lubrication: Like any complicated machine, an air conditioner has many moving parts. Regular maintenance should include the lubrication of these parts to ensure a continued level of optimal service.

Thermostat Caibration: A professional technician will also calibrate your thermostat as part of AC maintenance. Thermostat calibration ensures the proper function of your AC, and also increases its energy efficiency.

Cleaning: Over time, air conditioners collect dirt, debris, and worse. In the absence of regular cleaning, these airborne particles get endlessly cycled through your home. To ensure cleaner air and better operation for your unit, an HVAC technician should clean your AC’s coils and change its filters.

How Often Should You Have Your Air Conditioner Serviced?

An air conditioner should ideally receive service on an annual basis. This can allow the technician to not only perform the items listed above, but also identify repair needs before they cause trouble. These preventative repairs are perhaps the greatest benefit of annual maintenance, as they correct problematic issues before they become full-blown problems. Maintenance for your complete HVAC system should occur on a seasonal basis: in spring for the air conditioner, and fall for the furnace. The choice of these times ensures that your HVAC can handle the highest of seasonal demands.

Keeping Your House Cool And Your Bill Low

When it is hot and sticky here in Florida, it can be almost unbearable to not have the A/C turned on. It feels great until the end of the month comes and you get the electric bill and see the price of staying cool. There are a few simple things that you can do that you may not have thought of that will help you keep cool allow you to keep a lower energy bill. There will be times that you do have to run your air and deal with the bill because there is no reason to live in your home and be uncomfortable, but with a few of these simple tricks, you may be able to get some relief.

Cool Down Your Home

Curtains – Curtains can be your best friend in the summertime. To keep your house cooler, turn down your air and shut all the curtains and blinds so that your home is as dark as possible. Once you have done that and you have lowered the temperature in your house, you can turn your air off and the house should remain cold for a while as long as no one is going in and out.

Fans – This is a simple one that some people don’t even think about. If you are just planning to sit around your house, you may just want to turn the air off your down and turn the fans on. This will be able to keep you comfortable at the very least.

Energy Efficient Tips For Your Home Air Conditioning

Energy Efficiency

Keeping Your Home Energy Efficient This Summer May Not Be As Hard As You Think.

With summer almost here, it is time to get that AC turned on! One big concern many homeowners have during the summer months is how to keep their home energy efficient and keep your utility bills low. It may seem impossible with rising heat, however, there are some things you can do to ensure your home stays cool while not breaking the bank. The Kool My Air, Inc. team have compiled a list of things you can do for a more energy efficient home.

Ways To Increase Efficiency

  • Check Your Insulation – Quality insulation in a home can help your property retain cool air during the summer time and prevent the outside weather from entering your home. You can check this by going to your attic and looking at your roof structure.
  • Close Your Blinds – During the winter, having your blinds open can naturally warm your home. However, during the summer, you want your home to be cool. Control how natural light and UV rays affect your home by closing your blinds.
  • Use Your Thermostat – Set your thermostat at a good average temperature so that the system is not overworking. If you have a programmable thermostat, you can set it to be only on and off at certain times of the day, reducing the use of energy when no one is home.
  • Update your Home Air Conditioner – One final way you can improve your energy efficiency is to replace your old system with a new one designed to be more energy efficient. Newer models can even tell you their efficiency rating. If you choose this option, speak with your local heating and air conditioning company to get the best model and size for your home.

Ductless Air Conditioning- What You Need to Know

In most homes, some variance of central heating and air is in place. However, in older homes or homes with small central systems, and a ductless unit could be ideal. Ductless air conditioning units work to provide cooler air in an energy-efficient way to areas with high heat or no duct A/C. There are two main types of ductless A/C that can benefit your home.

Ask Our Experts if a Ductless System is Right For You.

Ductless Air Conditioners Provide Energy Efficient Cooling Without the Need for a Duct System.

Single Zone Options

These air conditioners work in one room to provide cooler air to a concentrated space. They use a wall or ceiling mounted blower along with a small outside condenser with refrigerant and power lines connecting the two. These systems provide reinforced cool air to areas with no duct or spaces that need extra cooling.

Multiple Zone Air Conditioners

Multi-zone ductless A/Cs offer the same effectiveness, only with multiple blowers that connect to your condenser. These small wall or ceiling units deliver optimal air filtration along with cooled air right where you need with adjustable airflow and delivery systems. When you are looking to utilize a ductless system for your entire home’s air conditioner, a multi-zone option works best to keep your home cool and energy costs down.

Whether you’re looking for an option to reinforce your current A/C unit or you need a ductless system for your older home with no central air conditioner, the Kool My Air, Inc. experts can help you choose the perfect model for your needs. Call us today at 833-321-5665 to learn more about your ductless air conditioning options in Miami Beach, FL or to schedule your consultation.

Why is it so Hot?

When your air conditioning system isn’t blowing cold air, it can cause not only comfort issues but also increased energy usage and hot and cold spots within your home. Your A/C can quit blowing cold air because of a few different reasons, some of which are simple enough to fix without having to call a professional.

Don’t Live With Hot Air! Our Experts Can Help!


Thermostat Malfunction

Many times, your air conditioner not blowing air or blowing warm air could be because of a mis-set or broken thermostat. Fortunately, these are easily replaced and are available in varieties from basic temperature control to models that can be remotely controlled and adjusted.

Condenser Problems

If your A/C is blowing, but the air is warm, you could have a condenser problem. When your air conditioner’s condenser is dirty or not working, there is nothing to the air entering your house. A good way to tell if it’s the condenser is your air conditioner is running but putting out hot air. When you think you may have a condenser problem, a professional technician is the best way to go in most cases.

Refrigerant Levels

If your system’s refrigerant levels are low, it can cause your system to produce warm air instead. A simple recharge of your refrigerant system will get you back in business fast.

No matter why your air conditioning system is malfunctioning, the Kool My Air, Inc. experts can repair it affordably and efficiently. Call us today at 833-321-5665 to get your air conditioning system back on track and get your home’s comfort level back to normal. Call our experts to learn more about our services and how we can help you.

AC Maintenance is More Important Than You Might Think

Your air conditioner was built to be a lasting, reliable machine, able to endure many, many years of use in even very hot weather. It will only do this, however, if you take care of it. Those little maintenance tasks you have heard of–changing filters, cleaning coils, recharging freon, etc.–are not casual recommendations. Your HVAC technician wants you to have those done in order to maintain the life of your air conditioner. Without them, you could have far more problems than necessary with your air conditioner in the future. Don’t skip AC maintenance.

The Little Things

HVAC on Mulch

Don’t Neglect Your AC Maintenance; It’s Important.

Changing basic air filters is a very easy thing to do. If you don’t know how, you can always ask your AC technician. Your air filters should generally be changed once every month. You also need to rinse your system; you can ask how to do this, too. One of the most important things you need, in addition to these little things, is to have a professional come and inspect your system once or twice per year.

Almost any problem that your HVAC system may develop can be prevented, or stopped before it turns into expensive repairs. A maintenance schedule that includes regular professional inspections should be part of prevention. To create a prevention plan, just call your air conditioner company. You can get all the information you need on how to keep up with AC maintenance.

Our air conditioning technicians will help you maintain your system through the years. Just call your local air conditioning company, Kool My Air, Inc., at 833-321-5665. We’re here for your AC maintenance, repairs, and more in Miami Beach, FL.
