Where to Install a Ductless Air Conditioner

Monday, September 17th, 2018

ductless-air-conditioner-unitDuctless mini-split systems are constantly praised for their efficiency, low operating costs, and ability to both heat and cool your home. But there’s one thing that always holds people back from being completely sold…

Where the heck are you supposed to install that giant air handler?

Since it’s required that one unit occupy each room you want to heat or cool, it means you’ll need to install a big, rectangular air handler on the wall. It’s understandable that this could seem obtrusive. In reality, many homeowners completely forget about their air handlers, but it’s hard to see that before you install one for yourself. In this post, we’ll explain the basic requirements for placing a ductless mini-split unit.

What Might Go Wrong with Your Heat Pump Pool Heater

Wednesday, November 12th, 2014

*Air On Demand no longer offers pool heater services. Please visit our service page to learn more about our Florida air conditioning services.

When you first purchased a swimming pool, you intended to use it all year long in order to get the most out of your investment. Of course, you didn’t envision that the water could become so cool, even in the beautiful Florida weather. A cold pool can make it less enjoyable and can keep you from getting the most out of your investment, which is why many homeowners choose to add on a pool heater as well.

If you own a heat pump pool heater, annual maintenance is key to keeping it working as it should all year round. While these are some of the most efficient types of pool heaters available on the market, there are a few things that may go wrong over time. Let’s take a look.

  • Refrigerant Leaks: Heat pump pool heaters use refrigerant to absorb heat from the outdoor air, heat it up even further at the compressor, and transfer the heat to a heat exchanger through which water from the pool becomes heated. If refrigerant is low, you may notice insufficient heating or your system may fail to operate, and a technician will have to seal the leak(s).
  • Broken Fan Motor: A large fan draws in air from the outside so that refrigerant can absorb the heat. If the fan motor breaks due to electrical problems or debris blocking the motor, a technician may need to repair or replace the motor or the fan.
  • Heat Exchanger Problems: The heat exchanger is built to be fairly durable, but it could still fall victim to corrosion due to chemicals in the pool.
  • Faulty Compressor: The compressor is the unit that heats up refrigerant to an extreme temperature and raise the pressure so that it can heat the water and pump back through the unit. If this is impaired, it may require a brand new unit.
  • Improper Sizing: Unfortunately, a broken down pool heater, one that uses far too much energy, or a heater that doesn’t quite seem to do its job effectively may be the wrong size for your pool. Only let an experienced professional size your new water heater to prevent these sorts of problems from occurring.

Heat pump pool heaters are some of the most durable and efficient on the market, but they may need repairs at some point in time. Call Air on Demand for quality installation, maintenance or repair for pool heater in Kendall.

Signs You Need to Call for Commercial HVAC Services

Thursday, July 10th, 2014

*Air On Demand no longer offers commercial HVAC services – view a full list of our air conditioning services here.
 
If your business is housed in a building with a properly installed HVAC system to provide heating and cooling, you shouldn’t encounter many problems with operating. However, because commercial systems are required to run for many hours—far more than any residential system—they will suffer from a large amount of wear and tear. Although regular maintenance will go a long way to alleviating this issue, you may still need to call in professionals to handles repairs.

There are some of the signs that you may need call on commercial HVAC services in Kendall, FL. Make sure that you contact a company with experience on heating and cooling businesses; this isn’t a job that anyone familiar with residential HVAC can handle. Look to Air on Demand and our NATE-certified technicians for the next time you need service to restore the comfort of your workplace.

Here Are Signs to Call for Commercial HVAC Services

  • Uneven temperatures: A common issue that can occur in commercial HVAC systems is trouble with the zone dampers and the thermostats. Commercial systems are larger than residential ones, and they need to use multiple thermostats to control a large number of zones. When people in the workspace start to complain about rooms that are too stuffy or too cold, the issue may be with the zone control. It’s also possible that the packaged rooftop unit has lost cooling/heating power (such as because of leaking refrigerant). Call for professionals to look into the uneven temperatures.
  • Appearance of water condensation in the workplace: This is an issue specific to a Miami summer. Because air conditioning helps to combat high humidity levels (when it absorbs heat from the air, it also absorbs moisture), when it starts to malfunction, humidity inside the building will rise. This will first show up as condensation along windows and other external surfaces. At the first sign of condensation problems, call for assistance from repair professionals.
  • Strange smells from the vents: Acrid or moldy/musty smells coming from the vents usually point to repair issues. The burning smells sometimes point toward motor and electrical problems inside the rooftop unit(s) that will need to have technicians replace the burnt out parts. Musty and moldy smells usually indicate that there are leaks and breaks along the ventilation system that will require sealing. Bring in commercial specialists to look over the system and determine where the issues are and then fix them.

Air on Demand takes pride in the skill of our team for providing quality HVAC services in Kendall, FL. When the comfort of your employees, customers, clients, and/or tenants is in jeopardy because of a malfunctioning HVAC system, make us your first call.

Advantages of Rooftop Air Conditioning Units

Friday, May 30th, 2014

*Air On Demand no longer offers commercial HVAC services – view a full list of our air conditioning services here.
 
When it comes to keeping your business comfortable during a long Florida summer (and on into the warm fall and even times during winter), you need to have the most durable air conditioners working for you. If you have yet to install a rooftop package unit, we suggest that you look into this possibility for your next installment. Rooftop package units have numerous advantages.

Whatever HVAC system you choose to install for your business, you should turn to Air on Demand to handle the installation work as well as the regular maintenance and any repairs the system may need during its long services life. Call us today and talk to one of our NATE-certified technicians about how we can install a rooftop unit in Kendall, FL for your company.

Rooftop unit benefits

  • No need for a split unit: The standard central air conditioning system is a split system with an indoor unit and outdoor unit, which takes up extra space inside your business that you could more efficiently use for other purposes. With a rooftop package unit, all the components are stored in a single cabinet: the compressor, the evaporator coil, the condenser coil, and the blower fans. This not only frees up space inside your building, it also reduces problems from noise pollution, so you have a quieter workspace.
  • (Almost) no space limitations: The roof is the limit when it comes to the size of your commercial AC. You can have multiple rooftop package units together to supply as much air conditioning power to your business as necessary, without using up one extra inch of valuable workspace. No matter how big or how many rooftop units you need, they won’t become eyesores for the company either, since they remain well out of sight of all but helicopters.
  • Heat pump option: You can choose to have your rooftop AC installed as a heat pump, and that means you’ll have heating for the short winters taken care of at the same time—and no extra space needs to be sacrificed.
  • Humidity controls: Maintaining balances humidity is an important part of everyday life in Florida homes and businesses. Packaged rooftop units from Trane come with humidistat technology that can control the moisture level inside your business and regulate the introduction of fresh air, creating a work environment comfortable for everyone.

Turn to commercial professionals

To care for a rooftop unit or install an AC unit  in Kendall, FL requires the work of commercial HVAC specialists. Don’t trust this job to just anybody with a license: look to certified commercial experts, like those at Air on Demand. We have a long partnership with Trane to provide you with a variety of the finest products for commercial heating and cooling. Contact us today to prepare for the most comfortable summer your business has yet experienced.

Miami Air Conditioning Tip: Basic Components of Your AC System

Monday, March 11th, 2013

Now that the cooling season is upon us, many Miami homeowners are turning on their AC. But quite a few of them don’t know how their air conditioning system works, which can make it hard to tell if their system needs repair. While it’s up to us to ensure that your system operates at its full capacity, informing new and current clients about the basic components of your air conditioning system is also part of our job at Air on Demand.  The sooner you recognize a problem or lack of performance, the more opportunity our Miami air conditioning technicians have to fix that problem quickly. Lingering problems could turn into larger ones. When you need air conditioning repair, maintenance, or replacement, call Air on Demand.

All of the basic components work as part of a refrigeration cycle, not unlike the refrigerator that keeps your food cold. Here are a few of the most important components:

  • Refrigerant. Refrigerant is the chemical mixture that travels throughout the indoor and outdoor coil systems, passing through a condenser and an evaporator. When air passes over the coils, it is cooled and circulated throughout your home. While R-22 refrigerant is now being phased out for R-410A, which does not contain ozone-depleting chlorine.
  • Compressor. This motorized pump pressurizes refrigerant, which allows it to change into liquid and gas at certain points in the cooling cycle. It runs on electricity, and in a split system is typically housed in the outdoor unit along with the condenser.
  • Expansion valve. This device is located between your hot coils and cold coils, and it controls the rate of pressurized liquid refrigerant entering the evaporator.
  • Thermostat. The thermostat is the user interface of the cooling system. It allows you to create a set point, which is your desired system temperature. It communicates this to the air conditioning system itself and adjusts airflow accordingly.

Get the Most Out of Your Panasonic Ductless Split in Miami

Monday, November 19th, 2012

What do you want from the heating and air conditioning system in your Miami home?  You want it to heat and cool your home; you want it to be durable; and you want it to be efficient. These are features that come standard with the Panasonic ductless mini split systems. We want our customers to be comfortable all year long. which is why we recommend Panasonic ductless mini split systems. Below we’ve outlined some of the benefits of ductless split systems and how you can make sure that you’re getting the most out of your system.

How Ductless Mini Split Systems Work

With a ductless mini split system, each room has its own evaporator coil, there is no need for ducts. This unit circulates air inside the room and either heats or cools the air. This unit is connected to a condensing unit that is located outside your home.

Zone Control

One of the main advantages of the Panasonic ductless mini split system is that it offers complete zone control in your home. Because each room has its own unit, you can turn on the units that you need to use. For example, if you know that you’re only going to use the living room and kitchen for the whole day, you can turn off the units in the other rooms. This saves you the energy of having to heat or cool the rooms that you aren’t using.

Efficiency

Ductless mini split systems also offer a high degree of efficiency for your home. A furnace uses a fuel source, like natural gas, to generate heat. But with Panasonic’s ductless mini split system, it simply moves heat from one place to another. In cooling mode, the ductless mini split system moves heat from inside your home to the outside. In heating mode, it does just the opposite: it takes heat from the outside air and moves it into your home.

If you have any questions about Panasonic ductless mini split system in Miami, call the experts at Air On Demand. If you’re interested in capitalizing on the benefits of a ductless system for your home, we would love to talk with you about it.

Miami AC Tip: Sizing Ductless Air Conditioning Systems

Monday, July 9th, 2012

Proper sizing of your Miami air conditioning system is one of the most important factors affecting its operation. A system that is too small won’t be able to keep up, while one that is too large can lead to short cycling and excess humidity.

This applies not just to central air conditioning systems, but also to ductless systems. The main difference is that with ductless systems, not all systems have to have air handler units installed, so you don’t need to take every room into account. To get an estimate on what size ductless system you need, follow these 4 steps:

 1.       Measure each room

To start with, you need to know the area in square feet of each room room that will be cooled by the ductless system. To do this, measure the length and width of each room. For some oddly shaped rooms, you may need to divide it up into two or more rectangles and then add the square footage of each rectangle together to get the total area of the room. Exclude closets from your calculations.

2.       Convert area to BTUs

For each room, convert the area you just calculated into how much energy will be needed to cool them, which we measure in British Thermal Units (BTUs). As a rule of thumb, multiplying square footage by 25 will yield the approximate number of BTUs needed for that space. So, a 200 square foot room needs about 5000 BTUs for proper cooling.

3.       Consider the variables

There are other factors aside from square footage that determine a particular room’s heating needs. These variables include the local climate, the number of people usually in the room at one time, the number of appliances operating in that room and how well the room is insulated. A good general rule is to add 4,000 BTUs to the total for a kitchen and 1,000 for a bathroom.

4.       Add it all up

Once you have the BTUs for each room, add them all up to find the whole house BTUs, which is generally how split systems are rated and labeled.

Keep in mind that this only yields an estimate, and that there are plenty of variables to consider when sizing an AC system. Hiring a Miami AC professional to do a load calculation is the best way to get an accurate assessment of your home’s cooling needs. Call Air On Demand today if you are interested in having a ductless system installed in your home!

Miami AC Guide: Optimal Air Conditioning Installation

Monday, June 18th, 2012

Guideline #1: Air Circulation Clearance

Air conditioners, whether they are installed in Miami or Coconut Grove, need to be able to circulate the air around them. They draw the warm ambient air in to keep the refrigerant lines from freezing and pump the cooled air out into the home. So, the outdoor condenser units need enough clearance from outside walls, shrubs and other possible obstructions. When installing an outdoor condenser unit, they should be set far enough off the house that air can circulate easily and any surrounding shrubs or trees should be pruned back or removed. Improper circulation clearance can degrade the performance of the unit and significantly shorten its life.

Guideline #2: Refrigerant Lines

Refrigerant lines need some extra slack left in them to prevent possible damage. If a line is totally taut and the condenser unit were to move even a little bit – perhaps because of non-level ground or inclement weather – it can easily get damaged. Damaged lines can leak refrigerant, causing performance problems and potential health hazards.

Guideline #3: Proper Insulation

In addition to being protected from damage, refrigerant lines also need to be properly insulated. Inadequate or missing insulation can cause excess moisture and condensation from the lines, resulting in dehumidification problems, water damage and possibly even insect problems. Keeping refrigerant lines insulated also keeps performance high and operation costs low.

Guideline #4: Distance from the Home

There isn’t a set “proper” distance from the home for a compressor unit to be installed. It can work from just about any reasonable distance. The issue is just keeping the refrigerant lines at the right diameter for the distance, so that the refrigerant can flow properly.

Guideline #5: Level Ground

Finally, the outdoor unit needs to be installed on level ground, typically on a pad of concrete, vinyl or some other durable material. This helps ensure proper clearance (see guideline #1) and a unit that won’t move readily (guideline #2).

With an understanding of those five guidelines, you can have a reasonable idea of what a properly installed air conditioner looks like. Call Air On Demand today if you want more information about Miami air conditioning system installation!
