Air Conditioner Problems That Can Happen When You Don’t Change the Air Filter

Wednesday, August 27th, 2014

The air filter in your AC may help you breathe more easily as it keeps unwanted pollutants like dust and bacteria out of the air. But if you don’t maintain your air filter, these particulates can build up over time and clog the filter. Not only will this affect the quality of the air, it may also prevent your air conditioner from working as it should. Sometimes, problems with your air conditioner may be solved by simply changing the filter. But when a clogged filter affects other components of your system, you should call a professional for air conditioning repair as soon as possible.

One problem that may be fixed by simply changing the filter is low efficiency. The indoor portion of your air conditioner uses a fan to suck in warm air from your home and remove heat from the air. However, your air conditioner will struggle with this process if a dirty filter blocks airflow to the evaporator coil. As your air conditioner works harder and runs longer to cool the air, your energy bills go up. Luckily, this problem may be solved by simply replacing the filter.

However, some problems will require the services of an air conditioning repair technician. If the indoor fan cannot blow enough air over the evaporator coil, it may begin to freeze. A frozen evaporator may mean you feel limited cooling from your air conditioner or no cool air at all. And if you attempt to fix the problem on your own by scraping off the coil, you may only make it worse. Low airflow can cause problems for your home and other parts of your air conditioner, so seek repairs as soon as you notice the signs.

Check with your manufacturer to find out whether your air filter can be cleaned or whether you need to purchase a replacement filter. You should clean or replace the filter about once a month, although this number varies depending on use.

To keep problems from occurring with your air conditioner, call Air on Demand for regular maintenance. However, if your air conditioner does run into problems, call us today for air conditioning repair in Doral, FL.

3 Benefits of Ductless Mini Split Air Conditioners

Wednesday, August 20th, 2014

Ductless air conditioning as an option for home comfort has taken off during the last two decades. Originally, ductless mini splits were used primarily for businesses (they are especially popular for restaurants) but their numerous benefits have made them impossible for homeowners to pass up.

If your home is right for installation of a ductless mini split AC, you should give the idea serious consideration. We’ll look at some of the advantages you can enjoy when your go ductless for cooling down your home.

Air on Demand installs ductless mini split air conditioners in Miami, FL. This is a complex job, and isn’t something you want to delegate to inexperienced amateurs (or attempt to do yourself) so contact our team when you think that ductless is your best choice.

3 of the Benefits of Ductless ACs

  • They also provide heat: Ductless air conditioners are actually ductless mini split heat pumps. That means they can provide heating as well as cooling. Heat pumps are excellent for Florida weather, since they work as well as any standalone air conditioner of comparable size and can ably handle our mild winters while in heating mode.
  • They help protect indoor air quality: One of the unfortunate problems with ductwork is that it collects dust, dirt, dander, and other contaminating particles, which is then blown out into your home’s air and recirculated. Only regular duct cleaning can prevent this. When you eliminate ducts with the installation of a ductless mini split, you take away this reservoir for pollutants and help keep your air healthier without the need for regular cleaning. If you have people with allergies or asthma living in your home, going ductless can make their lives much easier.
  • Energy savings: Ductless mini split heat pumps send conditioned air into your home through wall-mounted blower units, each which connects to the outside unit. Because you can individually control the blowers, you only have to send conditioned air to the parts of the house that need it. Unlike a central AC, you don’t have to cool down the entire house each time the system comes on, and this will lead to a reduction in your utility bills. You will also reduce the energy loss that can happen along the length of ductwork, increasing your savings.

Ductless mini splits are not right for every home: they work best for new construction, remodeling, add-on rooms, or for older and historic homes that lack the room for ducts. If you are unsure about installation, call the professionals at Air on Demand. We can look over your home and your current AC and determine if installing one of our ductless mini split air conditioners in Miami, FL is your best option for year-round comfort.

How Do Commercial HVAC Systems Differ from Residential Systems?

Wednesday, August 13th, 2014

*Air On Demand no longer offers commercial HVAC services – view a full list of our air conditioning services here.

Would you mow several acres of lawn with a push mower, or use a motorcycle for a family of 5? These are strong examples, but they demonstrate one of the key ways residential HVAC systems are different from commercial ones: size. While there are common, fundamental mechanics between commercial and residential systems, the systems are not the same. Working with professionals who have the knowledge and experience needed for commercial HVAC service is important for both you and your business. For over 30 years, Air on Demand has been providing commercial HVAC services in Pinecrest, and our trained technicians are available for any commercial repair you may need.

What Are the Differences?

As we stated above, one of the biggest differences between commercial and residential HVAC systems is their size. But there are others that are also important:

  • Many are packaged units – because commercial HVAC systems have to cover a great deal more square footage than the average household, they are often manufactured as one large unit called a packaged unit. These units are called packaged because all the components – the compressor, condenser and evaporator – are all housed in a single cabinet. This makes repair work easier because the components are more accessible.
  • Complex drainage – a commercial HVAC system covers large spaces; as such, the drainage system is far more complex than the simple condensate tray and drain you’ll find in a residential property.
  • Use of modular units – over the last few years, modular units have become very popular in the commercial HVAC industry due to their flexible nature. As businesses move in and out of spaces, cooling needs can vary; with a modular system, these needs can be met without having to re-design the cooling for that space. If less cooling is needed, one of the modular units can be removed; if more is needed, a modular unit can be added.

Having the proper amount of cooling is vital to your business. Do you really want to trust it to a company that doesn’t specialize in commercial HVAC services in Pinecrest? If you have been experiencing problems with your commercial HVAC system, call the professionals you can count on: Air on Demand.

What the ENERGY STAR Means for Your Air Conditioning

Wednesday, August 6th, 2014

While cost is an important consideration for most homeowners when shopping for a new air conditioner, the price tag should not be your sole consideration when searching for a system that will save you money. Air conditioning accounts for a large portion of energy bills in the summer, so you should look for an energy-efficient system that will save money over time.

The U.S. government requires all air conditioning manufacturers to provide information about the efficiency of the unit. The rating system used to identify this is known as SEER (Seasonal Energy Efficiency Ratio). The SEER is calculated by determining the cooling capacity of an air conditioner in a standard cooling season and dividing this number by its total energy consumption. While the government only requires air conditioners to have a SEER of 13 or higher in order to be sold in the U.S., systems must have a SEER of 14 or greater to earn the approval of the Environmental Protection Agency.

The EPA has established a set of guidelines that air conditioners must meet to earn the ENERGY STAR. While a high SEER is an important consideration when purchasing a new air conditioner, you should also pay attention to whether or not your new system has received this distinguished symbol. ENERGY STAR systems meet strict guidelines of both performance and efficiency and release fewer pollutants into the air than conventional models.

While the ENERGY STAR label can help you determine energy efficiency, a high number alone will not save you money year after year. First, the system must be installed properly so that it doesn’t run into problems early on. Second, proper maintenance is necessary to ensure that your system remains efficient throughout its life. Be sure to clean or replace air filters about once a month and schedule maintenance every year. Scheduling maintenance with an AC technician helps restore some efficiency and improve performance.

An AC technician can help you find a system with the ENERGY STAR label, calculate the proper size, and professionally install the unit. For professional air conditioning service in South Dade, pick up the phone and call Air on Demand today to speak with a qualified technician about your AC needs.
