How a Miscalibrated Thermostat Impairs Your HVAC System

September 1st, 2014

A thermostat can make or break an HVAC system: you might have the most advanced heater and air conditioner installed in your home, but without an adequately working thermostat, you won’t be able to accurately control or program the system, resulting in inefficient performance and a lowering of comfort. Often, these malfunctions will resemble another type of repair trouble with the system, but when you call on technicians experienced with heating and cooling technology, they will quickly get to the bottom of the problem and find out if the thermostat is at fault.

In some cases, you should have a new thermostat installed to replace the damaged older one; this is an especially good idea if you have an older manual thermostat or a non-programmable digital model. Not only will the new thermostat take care of the repair trouble, but it will perform more effectively than the older one did and give you energy saving performance and better comfort.

Thermostat miscalibration

The most common problem that thermostats encounter, one that often goes undetected at first, is miscalibration. A miscalibrated thermostat will inaccurately gauge the indoor temperature, and will then turn the heater and air conditioner on and off at the wrong times—either running too long and running too short. It only takes a few degrees of miscalibration to throw off the comfort in your house and cause the HVAC system to start draining energy unnecessarily. If the thermostat causes the system to run longer than it should, it will also cause the heater or AC to age faster.

Another potential problem from a miscalibrated thermostat is “short cycling.” This happens when the heater or AC stops its heating/cooling cycle too early because the thermostat incorrectly read that the target temperature was reached. The system halts prematurely—only to turn back on a short time later and repeat the process. This places tremendous strain on the HVAC system, and it will cost more to run since heaters and air conditioners use up the most power when they start up.

If you have noticed uneven temperatures in your home, a heater or air conditioner that seems to come on and off when it shouldn’t, or a short cycling HVAC system, then call for professional repair technicians. If your thermostat is miscalibrated, they will set it so it reads temperatures correctly again. They will also advise you if they think that you should replace an older thermostat.

AC Question from Melbourne: How Does Ductless Cooling Work?

August 25th, 2014

Ductless cooling isn’t a new type of air conditioning, but it was more commonly seen in commercial properties like restaurants versus residential properties. These days, ductless AC is a popular choice among homeowners for a variety of reasons. One question our Next Generation Air & Heat, Inc., technicians hear frequently is, “how does ductless air conditioning work?” The truth is, ductless cooling in Melbourne is not that different from traditional split-system air conditioning, with the exception of a couple of features.

Components of a Ductless System

A ductless air conditioner uses an outdoor unit very similar to that of a traditional split-system AC. In this unit, as with a ducted system, resides the compressor and condenser. The difference comes with the delivery system: the indoor blowers. The indoor blowers of a ductless system house the coils and fans, (blowers are around 35” long) and deliver the cool air to your home. The blowers are connected to the outdoor unit via a conduit that holds a power line, drainage line and refrigerant tube. An outdoor unit supports up to 4 indoor blowers.

How Does the Cooling Work?

The system starts by turning on one or more of the indoor blowers. The refrigerant begins its cycle, entering the compressor, then the condenser, and then up to the blower. The fan in the blower blows your warm indoor air over the coils in the blower, and cool, conditioned air is blown into your room.

Blowers can be mounted flush against walls and hung from ceilings; they just need to connect to the outdoor unit via an exterior wall. Blowers can be easily mounted above doorways and windows, allowing for flexible placement.

What Are the Benefits of a Ductless AC?

There are several benefits to installing a ductless air conditioner:

  • No need for ductwork – as the name states, a ductless air conditioner does not need ductwork to provide whole-home cooling.
  • Customized comfort – the blowers offer you zone control, so you only cool the areas that need it, and at the temperature you want.
  • Energy efficient – the unit itself is energy efficient, but in addition, using only the cooling you need helps save energy, too.

Ductless cooling in Melbourne can be a great option for your home. If you are interested in finding out more, call Next Generation Air & Heat, Inc., today.

 

How to Tell You Need Duct Sealing in Merritt Island

August 18th, 2014

The AC maintenance process typically focuses on the mechanical parts of the system. However, a truly healthy system requires healthy air ducting as well. Ductwork can often be forgotten because it is not visible and is virtually noiseless. But air ducts need attention, just as any other part of your system, or it can suffer from cracks, holes and broken seals. One of the best ways to keep your ducts healthy for the long run is by scheduling professional duct sealing on Merritt Island. When done correctly, as by a company like Next Generation Air & Heat, Inc., your ductwork can last for years to come.

Signs You May Need Duct Sealing

There are a few common signs that you may need duct sealing for your ductwork:

  • High energy bills – faulty ductwork can account for up to 30% of total air loss. When your system leaks, there can be a significant reduction of cool air reaching your home for which your AC has to compensate. Whenever your air conditioner has to work harder, it needs to use more power, which can result in higher energy bills.
  • Whistling sounds – whistling sounds in your air ducts can indicate that air is escaping through broken seals and holes.
  • Multiple hot and cold spots – it’s normal to experience slight temperature differences throughout your home, but if you are experiencing definitive hot and cold spots, there may be an issue with certain ducts not delivering the right amount of cool air.
  • Extra humidity – are you feeling extra moisture in the air? Faulty ducts can allow the outside humid air into a duct, and the moisture in this air gets delivered directly into your home.
  • Development of mold and mildew – mold and mildew thrive in cold, dark, moist places, making your ductwork a great place to grow. One of the best ways to deter the growth of mold and mildew in air ducts is to seal it properly to reduce moisture levels.

Duct Sealing Is Not a Good Choice for a DIY Project

Ductwork is extensive, and large sections can be in hard-to-reach places such as crawl spaces and attics. It can also be challenging to find all the holes and cracks that need to be repaired. These are just some of the reasons it’s important to call a professional for your duct sealing in Merritt Island.

How AC Technicians Detect Refrigerant Leaks

August 11th, 2014

One of the most serious repair problems that an air conditioner can encounter is a leak that allows the chemical refrigerant to escape from the system. During normal operation, an AC doesn’t consume refrigerant, and it will retain its refrigerant “charge” (level) indefinitely. The only way to lose the charge is from leaking occurring along the refrigerant lines or in the compressor. A loss of refrigerant charge will both lower the air conditioner’s cooling power and lead to crippling damage to components, such as a compressor that burns out from overheating.

If you feel a plunge in cooling from your AC, notice ice developing along the indoor coil, or detect a hissing noise coming from one the cabinets, you may have a refrigerant leak.

Call the Melbourne, FL air conditioning experts at Next Generation Air & Heat Inc. right away. We’ll use the detection methods to locate the leak so we can keep your AC working its best.

The methods of refrigerant leak detection

Refrigerant leaks are usually small and difficult to see without proper training or equipment. It only requires a pinhole-size puncture to allow the high-pressure refrigerant to escape. Here are some of the ways that professionals locate these leaks:

  • Bubble solutions: This is the oldest leak detection technique, but is still effective for larger leaks. The repair technicians use squeeze bottles filled with soap solution to spray along the areas where a leak is suspected. The escaping refrigerant should cause the solution to bubble.
  • Electronic “sniffers”: This is one of the most common leak-technician methods. The “sniffers” are devices that create a high voltage spark which the technicians run across the refrigerant lines. The chemicals in refrigerant have an insulating effect on the spark that will cause it to drop, pointing out the leak location.
  • Halide torches: This is useful only for older refrigerants (R-22, once the most common refrigerant blend, but now in the process of being phased-out nationwide). Halide torches turn green in the presence of the chlorine within R-22.
  • Fluorescent detection: The technicians first insert a fluorescent-colored dye into the air conditioner’s system, and then scan UV lights over the lines. The escaping refrigerant containing the fluorescent dye will show up as green under these lights.
  • Ultrasonic detectors: The noticeable hissing noise that can lead a homeowner to suspect refrigerant leaks is also useful in pinpointing their location. Listening devices like ultrasonic detectors allow technicians to zero in on the exact location of the leak.

Experienced technicians will probably use a combination of the above methods to detect a leak in your air conditioner. Once they have found the spot, they will seal the leak. Afterwards, they will recharge the refrigerant in the system to its proper level and take care of any repair issues the loss of charge may have caused.

When you need precision repairs for your air conditioning in Melbourne, FL, call Next Generation Air & Heat Inc. We have 24-hour emergency service to make sure the vital cooling for your home is restored quickly.

Important Upgrades to Consider with Air Conditioning Replacement

August 8th, 2014

When you need a new air conditioner, finding the right AC company and installing the correctly sized air conditioner may seem to be the most important decisions you make. But there are so many upgrades and options to consider with new AC installation that you should talk to a technician about before air conditioning replacement. A technician can not only help you choose the system that’s right for your home, but can also tell you more about these important upgrades.

Energy Efficiency

Your older system may have lost some energy efficiency over the years, so your new system will be a welcome change. But consider making an even more efficient purchase by choosing a system with a high SEER (Seasonal Energy Efficiency Ratio) and the ENERGY STAR rating. This ensures that your new unit has met government regulations for both efficiency and performance, so you can save even more money every month without giving up your comfort.

Insulation

It’s important to keep in mind that purchasing an energy-efficient air conditioning system does not guarantee the lowest cooling costs. If you do not maintain your air conditioner every year and change the filters once every month, your unit will lose some efficiency. Furthermore, insufficient insulation may allow heat to move into your home or through the ducts easily. Your air conditioner works by removing heat from your home, but lack of insulation may delay this process and hinder the efficiency of your system. You may consider professional insulation services along with your air conditioning replacement.

Thermostats

During air conditioning replacement, you may be able to keep your older thermostat. However, replacing a manual thermostat will benefit your AC in many ways. Manual thermostats are often difficult to read, so you may end up setting the temperature one or two degrees lower than you need it, costing you more than you’d expect. Digital thermostats are accurate and programmable, so you can set the AC ahead of time for increased comfort and savings.

Why You Need Specialists for Commercial Air Conditioning Installation

August 4th, 2014

If you’re a business owner, or if you manage a commercial property, you’re probably busy dealing with a lot of important matters. So when you need commercial air conditioning installation, you may be willing to leave it in the hands of any air conditioning technician you can find. Commercial installation is a big job, however, and a technician who is not very experienced dealing with commercial systems may be unfamiliar with the complexities of these larger units.

When you need commercial air conditioning installation, call a specialist to ensure your system is installed correctly so that your AC will run smoothly for the life of the system. Here are some of the reasons you should only rely on a trained specialist for commercial air conditioning installation.

Get the Proper Size

A commercial specialist who has a lot of experience is more likely to choose the correctly sized system to suit the needs of your property. A system that is not the proper size may be unable to cool the entire building if it is too small, or it may short-cycle if it is too large, causing it to overwork and, eventually, fail.

Speed

Commercial air conditioning installation is a big job and takes a good portion of time to complete. However, an experienced technician should be able to complete the job in as little time as possible so that your business can stay open with little disruption. An inexperienced technician, on the other hand, may take up a lot more time putting your unit into place. In the middle of summer, this is not ideal for anyone involved in your business.

Zone Control

Many commercial units use zone control so that employees or tenants can adjust the temperature according to their own needs in different areas of the property. Zone control systems often use a complex set of thermostats and dampers, so a technician without experience with commercial systems may be ill-equipped to handle such an installation.

At Next Generation Air & Heat Inc., we have years of experience installing packaged systems on commercial properties throughout the area.

The Benefits of Zone Air Conditioning

July 28th, 2014

By now you’ve been able to enjoy the cooling comfort your air conditioner has been supplying for the first half of this summer. But have you wished that you could have better control over the temperature of certain areas of your home, or gotten tired of hearing complaints that someone is too cold while someone else is too warm? It can be a challenge to evenly cool an entire home from one thermostat, which is why you may want to consider zone-controlled air conditioning in Palm Bay.

What Is a Zone?

A zone is anything you want it to be – individual rooms, a group of rooms, a hallway, an entire floor – the choice is yours.

How Is a Zone’s Temperature Controlled?

The zone system is a series of motorized dampers that are installed into your ductwork. Each damper has a thermostat, and each thermostat is wired into a control system that manages when the dampers open and close, according to the temperatures that are set. You, as the owner, manage the control panel, so you have total temperature control over each zone.

What Are the Benefits of a Zone Control System?

  • Better energy efficiency – zone control system allows you to cool only the areas/rooms of your home that need it; you can turn off the cooling to other parts that are unused or unoccupied. Cooling what you need instead of cooling an entire house helps reduce your energy usage.
  • Customized comfort – with zone-controlled air conditioning, you can adjust the temperature for the needs of a specific space or person without having an effect on the rest of your home. This creates more effective cooling and better comfort.
  • Less strain on your system – when you need less cooling, your air conditioner cycles less; this puts less wear-and-tear on your system.

Ready to Get Into the Zone?

Zone-controlled air conditioning in Palm Bay offers a number of benefits that you simply won’t get with a single thermostat. However, installing a zone control system is not a do-it-yourself kind of project.

If you think a zone control system is a good fit for your home, call the experts at Next Generation Air & Heat, Inc., and schedule an appointment with one of our experts.

Why Dryer Vent Cleaning Is So Important

July 21st, 2014

Every time you use the dryer, one of the key steps is to clean out the lint filter before you start up the cycle. If you don’t, your clothes will not dry as fast and the dryer will run for longer, wasting power. This same principle applies to the dryer vent that runs from the dryer to the outside of the house, although on a larger scale and with more important implications.

The dryer vent exhausts the heat from the inside of the dryer to the outside, and it also takes a large amount of lint fibers with it, which will start to build up inside the vent. You should have the dryer vent cleaned out on a regular basis to remove the link accumulation, usually once annually, although if you use the dryer frequently you may need to schedule cleaning more often. A professional service can take care of this job for you fast and effectively. Contact Next Generation Air & Heat Inc. today and arrange for dryer vent cleaning in Palm Bay, FL.

Why is it so important to have the dryer vent cleaned? There are two reasons:

  • Fire safety: The heat inside a dryer is intense—it has to be in order to dry clothes in a short, efficient time. But a dangerous side effect of this heat is that it can cause fibers, which are highly combustible, to burst into flames and start a house fire. This is a serious problem that caused 15,000 fires in 2010 alone in the U.S. This isn’t a risk that you want to take with your dryer, so make sure that it is professionally cleaned. Also, a dryer that is not venting properly will become excessively hot on the outside, which can be dangerous for people who might touch it.
  • Dryer efficiency: The same way a blocked lint filter will keep your clothes from drying effectively, a clogged dryer vent will cause your dryer to run inefficiently in general. The inability to vent the air from the inside of the dryer will trap moisture inside and make it much harder to dry your clothes. You will need to keep the dryer running longer and longer in order to reach the desired temperature. Not only will this raise your bills, but it can damage your clothes.

If you notice that your dryer is no longer working as well as it once was, and you keep finding damp clothes at the end of the wash cycle, then you probably have a clogged dryer vent and need to call for professionals to clean it before it turns into a safety hazard.

Next Generation Air & Heat Inc. can offer you fast & professional service whenever you need dryer vent cleaning in Palm Bay, FL and the surrounding areas. 

Why Should I Get Packaged Air Conditioning Units for my Home?

July 14th, 2014

If you’re looking for a convenient air conditioning system that won’t take up space inside of your home, a packaged air conditioning system may be the right choice for you. While many homeowners choose split systems, which require both an indoor and outdoor unit for installation, packaged air conditioning systems combine the evaporator and condenser units into one, allowing for convenient placement options and ease of maintenance.

If your home already has an indoor furnace, split system air conditioning is often the most cost-effective choice. However, if your home is not set up for a split system, you may decide to call a technician to install a packaged system instead. Packaged air conditioning units are usually installed right outside of your home. The entire refrigeration cycle takes place within this single unit and cool air is provided through the ductwork of your home.

Packaged air conditioning units have several benefits. They contain the same components of a split system, but these are all housed in one outdoor unit. This is useful for those whose homes make indoor installation difficult or who don’t have the space for a separate indoor unit. They can often be used for both heating and cooling so that there is no need for a separate heating system.

Another benefit of a packaged system is that a technician can often access your system with ease, which means repair and maintenance calls may be completed quickly. With split systems, the technician has to move between two separate cabinets in order to access your entire system, but packaged systems allow for less back-and-forth, which means you can switch your air conditioner back on sooner.

Packaged air conditioning units rely on the existing ductwork in your home in order to circulate air. If you do not have ducts installed in your home, a packaged system along with ductwork installation may be costly. In this case, you may consider ductless options, such as a ductless mini split system.

If you think getting a packaged air conditioning installation is right for your Melbourne home, call Next Generation Air & Heat Inc. today!

How Do Energy Recovery Ventilators Work?

July 9th, 2014

During our Florida summers, you can count on three things: high temperatures, high humidity and the running of your air conditioner. While we can’t change the outside temperature or humidity, there is a great tool (other than your air conditioner) to help with the inside temperature, humidity and energy efficiency: energy recovery ventilators.

Used for some time in commercial buildings, energy recovery ventilators have helped with all of the above, and have other benefits they can provide. Is an energy recovery ventilator right for your Rockledge property? The best way to know is to work with a professional from Next Generation Air & Heat, Inc., who understands the benefits of installing one.

What is an Energy Recovery Ventilator?

An energy recovery ventilator (ERV) facilitates the transfer of heat and moisture between the incoming fresh air and outgoing stale air. The core of the ventilator separates the exhaust air from the fresh air, then transfers the temperature (heat energy) and humidity of the outgoing air to the incoming air. So, during winter, the fresh, incoming air is pre-heated and humidified, and in summer, the fresh, incoming air is pre-cooled and dehumidified. The result is an incoming stream of fresh, energy-efficient air and the expulsion of pollutants and stale air.

What Are the Benefits of an ERV?

There a several benefits to adding an ERV to your air conditioning system:

  • Continuous clean air – with constant, fresh air being streamed into your air conditioner’s system, an ERV ensures that the air coming into your home is both fresh and efficient
  • Better indoor moisture control – the ERV removes humidity from the incoming air during the summer and adds it to the dry air coming in during winter; this allows for better control over humidity levels year-round
  • Better energy efficiency – with the ERV’s ability to either warm or cool the air (depending on the season), your air conditioner will use less energy to cool, creating better energy efficiency. This is the same for the moisture control aspect of the ERV.

Questions About Energy Recovery Ventilators? Call an Expert

An energy recovery ventilator can be a great addition to your air conditioning system in Rockledge, but it is not an installation job for someone without training.

To find out if an ERV is a good fit for your air conditioner, call Next Generation Air & Heat today and schedule a consultation with one of our experts.
