What’s The Noise? Sounds That Could Indicate It’s Time for AC Repair

April 18th, 2014

Here in Jacksonville, FL, air conditioning repair is almost as important as auto repair. You need your AC unit to function during the heat of the summer, and summers don’t get any hotter than they do in Florida. The minute you spot signs of a malfunction, you should turn off the unit and call a qualified repair technician. Noises are a good sign that something is wrong, and generally speaking, any noise that you don’t recognize as part of the normal operation of your system should be a cause for concern. But more specifically, you can determine a bit about the nature of the problem just by listening to the odd sound. What’s the noise? Here’s a list of some sounds that could indicate it’s time for AC repair.

  • Rattling or clanking – These kinds of sounds likely indicate a problem with the blower motor or compressor motor, which are among the most important components in the system.
  • Buzzing – A humming or buzzing noise typically comes from electronic components in distress: from bad connections, frayed wiring or the like. Occasionally, a humming sound can come from vibrating ductwork near the spot of a breach or tear in the ducts.
  • Grinding noises – Grinding noises usually arise when two components are rubbing against each other and creating a lot of friction. This usually involves a fan with bent blades or a misaligned position. Sometimes, it can come from twigs and other debris caught in the system.
  • Clicking – A clicking sound usually comes from the relays when the system starts up. It’s not normally a problem, but if the clicking sound persists, you may have a problem with your thermostat.
  • Hissing – Hissing noises usually indicate a breach in the line, most likely a refrigerant leak.

What you know what the noise is and hear sounds that could indicate it’s time for AC repair, call the experts at J & W Heating & Air for help.

What is a Ductless Mini Split?

April 14th, 2014

Whether you’re looking for an energy efficient alternative to ducted systems like central air or heat pumps, or merely thinking about upgrading your system to avoid some of the indoor air quality issues associated with ductwork, a ductless mini split makes an excellent solution for year-round heating and cooling. As a type of heat pump, it shares many similar characteristics, and it uses the same type of refrigerant cycle that all air conditioners use. But perhaps because of the strange name or because of their lack of ducts, many customers are not sure what to make of ductless systems or how they work. We’d like to clear up some of the mystery. Call J & W Heating and Air today for excellent ductless mini split and other air conditioning services in Jacksonville, FL.

As we already suggested, a ductless mini split system uses a similar setup to conventional heat pumps and central air conditioners, but there are some important differences. The lack of ducts would seem to present problems for air distribution, but as we shall see, this can actually be an advantage. The outdoor unit of both ductless and conventional systems is more or less the same. It contains a compressor and a condenser where the thermal energy is dissipated and drawn in, depending on the season. But the indoor unit is much different.

The indoor unit of a ductless mini split is relatively compact. It sits within the living space itself, often high on a wall or suspended from a ceiling. It does everything a conventional air handler does, except without ducts. It connects to the outdoor unit by a series of refrigerant, drainage, and electrical lines, which means that the outdoor unit can actually be located much further from the home than in conventional system setups. A ductless mini split also gives you the option of having multiple indoor air handlers installed throughout the home, so that each distinct zone can be controlled separately. This can help you cut down on energy costs while also improving comfort.

Call J & W Heating and Air today when you’re ready to get started on your Jacksonville, FL ductless mini split installation. 

Ways to Improve Indoor Air Quality

April 7th, 2014

The quality of the air in your home is every bit as important to you comfort as the temperatures therein. That is why our team is devoted to helping you find the best ways to boost indoor air quality in Jacksonville, FL. You really must schedule your indoor air quality services with a trained professional if you want to tackle the problem head on. There are a number of different issues which may plague your air, and only a specialist can determine with certainty how best to resolve the situation. Call J & W Heating and Air today if you have any concerns at all about the quality of the air that you breathe in your home.

A very common problem that a lot of homeowners encounter with their indoor air quality is the presence of airborne pollutants. Air filtration systems are a great way in which to reduce the concentration of such substances throughout your home. You are probably aware of the fact that there is an air filter in your HVAC system. The purpose of such filters, though, is to protect the condition of that equipment. They have low MERV (minimum efficiency reporting value) ratings, and are not intended to boost indoor air quality. A designated mechanical air filter or an electronic air filtration system, on the other hand, can clean up the air in your home.

Biological pollutants are a whole different game entirely. When mold, viruses and bacteria try to take over your home, certain measures must be taken. Pollutant destruction, rather than filtration, is the answer. UV germicidal lights can help to minimize the risk posed by these invaders. Using UV (ultraviolet) radiation in small doses that are safe to us can destroy such biological pollutants and prevent them from negatively impact ng your comfort or your health.

Even the humidity levels in your home can play a role in determining the quality of the air throughout the house. Don’t think that very humid or dry air is no big deal. Both can lead to a number of different problems. With the right humidifier or dehumidifier in Jacksonville, FL, though, you can balance humidity in your home for improved comfort and air quality.

Let J & W Heating and Air know what concerns you have about the air quality in your home. We will find the appropriate solution. Contact us today to learn more.

Why You Need a Professional Air Conditioning Installation

March 31st, 2014

Florida, as is common knowledge, gets extremely hot throughout the summer. Because of this, a quality air conditioning system is an absolute necessity if you hope to make it through the hottest time of the year in complete comfort. To think that a great air conditioner on its own is enough to help you achieve this goal, though, is foolish. You must pair your air conditioning system with a professional air conditioning installation in Jacksonville, FL if you truly want to protect your comfort. There is no other way to get the best performance that your air conditioner has to offer. Call J & W Heating and Air for the AC installation you need to keep cool this summer.

First things first, no air conditioning system will operate effectively and efficiently if it is not the right size for the space in which it is installed. As you can see, there are important decisions which must be made even prior to the installation of your new air conditioner. Only a professional air conditioning installation technician can size your AC appropriately so that it works as well as it should. If the system is too small, it will struggle to reach target temperatures. This will put unnecessary wear on the machinery, and the constant running will result in high cooling costs for a subpar cooling performance. An oversized system will fare no better, short-cycling frequently and dragging down air quality to boot. Plus, that stopping and starting increases the risk of damages to your system.

There is also the design of your air conditioning system to consider. If you use a heat pump, central AC or geothermal heating and cooling system, you are going to need air ducts to circulate cooled air throughout your home. The design of this ductwork is vital, as is the quality of its installation. If there are unnecessary twists and turns or poor seals in the system, you are going to wind up wasting energy while cooling your home.

From the installation of your ductwork to the placement of your thermostat, our technicians will do everything it takes to ensure the success of your air conditioning installation in Jacksonville, FL. Call today to schedule service.  We want to make sure that you are able to beat the heat this summer.

Why Consider Ductless Air Conditioning in Jacksonville, FL?

March 24th, 2014

A common misconception that some homeowners share is the idea that an air conditioner is an air conditioner: in truth, there are many different AC options for you to choose from. Each should be carefully considered, as not all air conditioning systems are appropriate for every home. You shouldn’t feel overwhelmed when choosing your new air conditioning system, though, because J & W Heating and Air is always here to help you make an informed decision about how best to cool your home. One great option to consider is ductless air conditioning.

The simple truth is that some homes are not able to accommodate the system of air ducts which forced air distribution systems require in order to distribute conditioned air throughout the home. Contrary to what you may think, though, this does not mean that you must rely on inefficient window units in order to keep your home cool throughout the hottest time of the year. There is a great whole house cooling option which is perfectly designed for just such a situation: ductless AC.

Ductless air conditioning systems, as you’ve probably guessed, do not require air ducts in order to cool your home down. Instead, they use wall mounted blowers to cool areas of your home down directly. These blowers are connected to an outdoor unit via a simple conduit containing power and refrigerant lines. A benefit of this design, aside from the space that it saves, is the fact that no energy is wasted while conditioned air is circulated through ductwork. This helps you to cool your home in a more efficient manner.

Also boosting efficiency is the fact that the wall mounted blowers, regulated by individual thermostats, make zone controlled cooling easy. Why bother cooling down empty rooms upstairs just to keep your guests in the dining room comfortable? With ductless air conditioning, you won’t have to.

Let J & W Heating and Air share the benefits of ductless AC with your household. No air ducts does not equate to subpar comfort any longer. Give us a call today and take advantage of all that ductless air conditioning in Jacksonville, FL has to offer. 

Problems with Humidity in Jacksonville, FL

March 17th, 2014

Everybody understands that effective temperature maintenance is necessary if you want to enjoy a comfortable living environment in your home. What fewer people realize is the immense impact that humidity levels can have on your comfort. If there is too much or too little humidity in the air within your home, a number of different problems may develop. These problems can cause issues with your comfort, your indoor air quality, and even the condition of your home and property. Recognizing such problems is important, and J & W Heating and Air has the information that you need to do so. If you notice these issues in your home, investing in a humidifier or dehumidifier in Jacksonville, FL may be necessary.

Too Little Humidity

When humidity levels fall below where they ought to be in your home, there are a lot of different symptoms that can alert you to the problem. You may find that your skin is very dry and itchy. You may also wake up with a sore throat or even suffer from frequent nosebleeds. Very dry air does not hold heat well, which may render your heating system ineffectual on cooler nights. Static shocks may be a regular occurrence, and paint can chip away from your walls. If the air is dry enough you may even see splits in wooden furniture or floor boards throughout your home. A quality whole house humidifier is your best option if you want to inject the right amount of humidity back into the air in your home.

Too Much Humidity

Excessively humid air is no better than very dry air, bringing with it a bevy of possible problems. As stated above, dry air does not hold heat well. Conversely, very humid air can hold heat too well. This can result in very stuffy conditions within your home, a major problem here in Florida. Plus, high humidity levels can promote the growth of biological pollutants, including viruses, mold and bacteria. Keep your home cleaner and make it a more comfortable environment with a dehumidifier.

No matter what humidity problems you may have, J & W Heating and Air is the company to call. Let us handle your humidifier and dehumidifier installation, repair and maintenance services. Your comfort is our top priority.

Improving Efficiency in Your Jacksonville, FL Home

March 10th, 2014

It is no big secret that temperatures in Florida can be oppressive throughout the long, arduous cooling season. Because of the extreme nature of our summer heat, you are going to have to use your air conditioner with great regularity. Homeowners know all too well the high costs that accompany this need for cool, conditioned air.

Keep these suggestions in mind, and remember that our technicians are always available to provide any air conditioning services that you may need to make your AC more efficient and effective.

When it comes to boosting air condition efficiency, it is advisable to start small. You do not necessarily have to invest in a brand new, top of the line air conditioning system to improve the efficiency with which you cool your home. One great way to do so is simply to make use of any ceiling fans throughout your home. Take advantage of the cooler temperatures during the early morning hours or the time between dusk and going to bed. Open up your windows, raise the thermostat and, and let your ceiling fans circulate some fresh, cooler air throughout your home. This will also allow for some much needed ventilation, keeping the indoor air quality in your home high.

If you are really concerned about high cooling costs, remember that your air conditioner may not be directly to blame. The insulation in your home may not be adequate to keep heat from transferring into your living space. In this case, our insulation technicians can assess the situation and, if necessary, provide you with proper insulation, including blown in insulation for those  hard to access areas. Even installing some weather stripping in your door and window frames, easily obtained at your local hardware store, can help to keep your home cool in a more efficient manner.

Signs That You Need Professional Duct Sealing

March 3rd, 2014

Living around here, you understand just how important a great performance from your air conditioning system is. Of course, the heat falters now and then. That is why you also value the effective performance of your heating system. Regardless of how great your heating and cooling equipment may be, though, you cannot expect it to operate as efficiently and reliably as possible if you do not have quality air ducts. Leaky ductwork is a major player in energy loss and IAQ issues. If you have any reason to suspect problems with your ductwork, call J & W Heating and Air right away. We’ll make sure that your ducts are in outstanding shape with our duct sealing in Jacksonville, FL.

One easy to spot sign that you may need to schedule professional duct sealing is a spike in your energy costs. This is pretty obvious when you think about it. If you use a forced air distribution system to distribute heated and cooled air throughout your home, then all of that air that you have paid to condition must travel through your ductwork to reach its destination. If that ductwork is leaking air out of the system, then your HVAC equipment will have to work overtime in order to replace that wasted energy. Needless to say, this can easily result in costly heating and cooling experience. Quality duct sealing may be your best option to boost energy efficiency in your home.

Another indicator that you may need to schedule professional duct sealing is a drop in your indoor air quality. When your air ducts leak, they not only allow conditioned air to get out, after all. They may also allow pollutants to find their way into your ductwork. This is a major problem, as your air ducts can just as effectively distribute these pollutants throughout your entire home as they can conditioned air.

Regardless of your reasons for scheduling duct sealing in Jacksonville, FL, we are the company to call. Our technicians have the training, tools and experience they need to ensure that you get the most from your air ducts. Do not allow leaky ductwork to set back your comfort or your indoor air quality during the heating and cooling seasons.

When to Schedule Duct Cleaning

February 25th, 2014

Right now, this very minute while you look at a browser window, dust is gathering inside the ventilation system of your home. The air entering the return ducts draws in dust and dirt from your home, and it settles inside the sealed environment of the ducts, where it will begin to build up. Given enough time, this contamination will cause a drop in your indoor air quality and will put strain on your heating and cooling system.

To combat the problems of dirty ductwork, you need to schedule duct cleaning in Jacksonville, FL. Look no further than the technicians at J & W Heating and Air to provide you with the cleaning services you need.

Times when you should schedule duct cleaning:

  • When your ducts are extremely dirty: This sounds obvious… but how can you tell you have dirty ductwork? Go to one of the vents in your house (the ones located on the floor are easiest) and unscrew the grill from the front and take a look inside. If they are covered with dust and dirt—something like what you might see inside a full vacuum bag—then you definitely need duct cleaning.
  • When you notice an increase in allergy and flu-like symptoms: If your ductwork is lowering the quality of your indoor air, it will begin to cause conditions like dry and irritated skin, runny noses, headaches, nausea, and breathing problems. People with allergies will be especially susceptible, but you don’t need to have allergies to suffer from similar problems due to poor air quality.
  • Once a year: Annual duct cleaning is the best way to keep your ductwork in the cleanest condition. A year is enough time for a layer of dust to build-up along the interior of the ducts, and even if it isn’t yet affecting your indoor air quality, this contamination will start to restrict the flow of air and reduce the effectiveness of your air conditioner, furnace, or heat pump. Make professional duct cleaning a yearly habit.

Only professionals can truly clean your ducts

Duct cleaning is much more than pushing a broom through an open vent. Your ductwork system is extensive and much of it is out of your reach. You will need professionals with agitation equipment and power vacuums to perform the job. They can also inspect your ducts to see if you need other help, such as UV purifiers or filters.

In Jacksonville, FL duct cleaning specialists at J & W Heating and Air are ready to help you with cleaner air and a more efficient HVAC system. We offer not only duct cleaning but a variety of services to improve your indoor air quality.

Benefits of Heat Pumps

February 17th, 2014

The heat of a Floridian summer is truly a force to be reckoned with. Keeping your home cool throughout the hottest time of the year is challenge enough. At times, doing so efficiently can feel downright impossible. If you are sick of paying too much money to keep your home comfortable throughout the hottest time of the year, contact J & W Heating and Air today to learn how using a heat pump in Jacksonville, FL can benefit you. These unique systems are able to help you maintain comfortable temperatures in your home with greater efficiency than you may have thought possible.

The reason that heat pumps  are such an efficient HVAC option is due to the fact that they rely on the heat transfer process in order to keep your home comfortable. During the summer months, a heat pump acts much like a traditional air conditioning system. Heat is removed from the air in your home, and that cooled air is then redistributed throughout the house via a system of air ducts. However, heat pumps are also able to reverse this operation.

The mild Florida winters make heat pumps a great solution for heating your home efficiently as well. Even when the temperature drops, there is still heat in the air outside. By using this ambient heat to warm up your home, a heat pump can keep you comfortable throughout the heating season using just a small amount of electricity in the heat transfer process. The result is very efficient, reliable comfort all year long. Needless to say, even the most efficient heating and cooling systems will fail to impress if you do not schedule your heat pump installation, repair and maintenance services with a skilled, qualified professional. To do so you need only dial our number.

The heat pump professionals at J & W Heating and Air are here to answer any questions you may have regarding the installation of heat pumps in Jacksonville, FL or the benefits that using one can provide you. Call today for more details. Let us help you live in the comfort you deserve throughout the year.
