Sarasota Springs HVAC Guide: Why Routine Maintenance Improves IAQ

Monday, March 26th, 2012

Furnaces and air conditioners in Sarasota Springs are by far the most common way to circulate air throughout homes, offices and institutions, heating in the winter months and cooling in the summer.  Adjust the thermostat and controlled air is delivered almost immediately.

If a system is not regularly and properly maintained, however, that air can be dirty, dusty and full of odor, having passed through the heat exchanger, filters and ductwork that have accumulated a build-up of residue over time.  IAQ or interior air quality quickly deteriorates.

The Basics

HVAC systems heat or cool air at a central point. The air passes through filters to sift out dust and unwanted particles, then travels through a system of ductwork to be delivered to the space.  Return air ducts bring it back to the central point.

Along the way, the air accumulates the dust, germs and debris of the places it inhabits.  Over time, the filters become clogged and eventually contribute more contamination to the processed air than they can clean.  The enclosed and hard to reach ducts are also deposits of dust and decorated with spider webs that are quickly another form of filter that gives back more than it receives.

The Costs

Without routine maintenance, the system runs poorly and distributes more dirt into the living space than it is able to filter and clean, reducing the quality of life for the inhabitants, homeowners.  Poor air quality can lead to serious health issues.

Not only does the quality of the air decrease, the strain on the system lowers efficiency.  Having to work harder consumes more energy, creating an immediate and noticeable rise in utility bills.  The stress also reduces the lifetime of your Sarasota Springs HVAC system and requires more rapid replacements of parts or the entire furnace, a huge financial cost.

Regular Maintenance is the Easy Solution

To maintain high levels of quality air, it is essential to schedule regular replacements of filters and a clean-out of the ducts.  The filters are accessible as part of the furnace and air conditioners and easily swapped out by the home owner once or (better) twice a year.

Ductwork, however, is enclosed and often out of site, just as easily out of mind and certainly harder to reach.  Scheduling duct cleaning along with an inspection and routine maintenance of the entire system with a licensed company such as Baker & Sons Air Conditioning, Inc. ensures longevity and efficiency along with peace of mind.

Bradenton Air Conditioning Installation Tip: Why it Is Important to Examine Your Ducts

Wednesday, March 21st, 2012

For most Bradenton homeowners the day a new air conditioner gets installed is a great one. It means you can look forward to plenty of days of cool comfort, sheltered from the blistering summer heat that would otherwise make you feel sticky and sluggish.

Before that installation can take place, however, there are many smaller tasks that must be performed. You have to do some research, shop around, consult with a Bradenton HVAC contractor and finally decide on the best system for your home. Finally, you should have your ducts examined.

Your ducts are the pathway by which cooled air will be distributed through your home. Without regular maintenance, ducts are less efficient in transferring air and can cost you money, not only in electricity but in air quality control. Like any major component of your HVAC system, they need to be properly maintained to work properly.

So, you want your ducts to be in tip top shape for your new AC system. Having a professional inspect them thoroughly prior to installation will identify any damage, dirt, debris, leaks, corrosion or other trouble spots that could impede your air conditioning.

This gives you the opportunity to get any of those problems fixed before the new system is installed. Plus, a professional inspection is an important part of routine duct maintenance anyway. Having it done at this juncture is easier and ensures you know will have a smooth running air conditioner for some time to come.

Having duct work in good repair is vital to the operation of your HVAC system, including the new AC system you want to install. If you are contemplating having a new air conditioning system installed or even if you are not, now is the time to call Baker & Sons Air Conditioning, Inc. for full inspection of your ductwork. Especially if you have a forced air heating system and those ducts are used year round, you want to know for a fact that they will work properly in the future, no matter what is hooked up to them.

Your Branches Hammock HVAC System and the Gas Line

Wednesday, March 7th, 2012

What happens if you lose your gas line? What relationship does that simple copper pipe have to the comfort control of your Branches Hammock home? It depends largely on the scope of your HVAC system and what time of the year you lose gas, but the answer is almost always that it will have a pretty big impact.

What Uses Gas in Your Home?

There are a number of components that use gas in your home. The first and most common is your furnace, but you will find that your water heater may also use a gas line and some packaged air conditioning systems use gas for heating components.

  • Heating – If you have a gas line, it’s very likely that your heating system uses gas as an energy source. It’s the least expensive of the three major energy sources (oil, gas and electricity) and gas furnaces are extremely efficient. In terms of how much gas you will use, one cubic foot of gas contains 1040 BTUs of heating energy per hour.So, if your furnace offers 100,000 BTUs of heating capacity, it would use 96.15 cubic feet of natural gas when running at full capacity. Keep in mind, though, that a gas furnace is rated with an AFUE rating. This is the percentage of the fuel consumed that is actually converted to heat. So, if your AFUE rating is 90%, your actual BTU production would be 90,000 for the same 96.15 cubic feet of gas. The cost of natural gas varies by location, but is generally around $1 per cubic foot.
  • Water Heating – For a water heater, gas rates are charged by kWh. Your water heater should have a placard or sheet that lists its maximum production per hour so you can determine how much gas it uses per hour when your hot water is in high demand.

Gas is a highly volatile substance and while there are a number of safety measures implemented in your Branches Hammock home to protect your family, it’s important to ensure the gas lines are well maintained. Annual maintenance is a must to keep the gas working properly. If you do notice a leak or sudden loss of gas, don’t call a contractor – call the gas company immediately as it could be an emergency.

Bayshore Gardens Air Conditioning Repair Tip: Common Air Conditioner Problems

Friday, February 24th, 2012

Air conditioners are an important part of our lives in Bayshore Gardens. They keep us comfortable despite overbearing heat and humidity outside all summer, but because they run constantly for months and because they are such complicated pieces of machinery, they are prone to a number of problems. Here are some of the most common problems you’re likely to run into with an air conditioner and how to solve them:

 Leaks

A common problem that many people ignore or are unaware of is refrigerant leakage. It is possible that when the system was installed, it wasn’t properly charged, but most of the time if your system is low on refrigerant, it is because of a leak. You can’t just pour more refrigerant in and call it good, though.

The leak needs to be fixed, both for health and environmental reasons. If you notice that your system is low on refrigerant or you smell something off – often like acetone, call Baker & Sons Air Conditioning immediately for inspection and repair.

 Sensors

An air conditioner doesn’t do you any good if the sensors don’t work properly. Improperly working sensors will fail to properly read the temperature in the home or from your thermostat. So, it might be 80+ degrees in your home but if the thermostat reads it as 72, the system won’t turn on. The air conditioner itself probably still works fine, but unless it can successfully read the temperature, you won’t get the cooling you need to stay comfortable.

Check first to see if the sensor was moved or knocked toward the evaporator coil (which will keep the temperature reading low).

 Drainage problems

Your air conditioner acts as a dehumidifier as well, producing a liquid known as condensate. This liquid usually drains from the air conditioner into a designated area away from your Bayshore Gardens home. However, if the condensate drain gets clogged or if the system wasn’t properly installed, that condensate can start to build up in your home. If you notice leakage around the coils, you may need a pump to remove the condensate properly.

Properly maintaining your air conditioner can usually be done with regular maintenance each year, but if one of these problems pops up, call Baker & Sons and get them fixed right away.

Southgate HVAC Installation Question: What Is Involved in Replacing an Old System?

Wednesday, February 22nd, 2012

When your Southgate home’s HVAC system starts to fail — or if it already has — your options essentially come down to two: replace or repair. There are a lot of factors that go into making such a decision, but in general, if it is a newer system with a small problem and you haven’t had much trouble with it, then a simple repair clearly makes sense.

For older systems, or ones that have been repaired all to often lately, or ones that seem to be on their last legs, repair may be the only reasonable course of action.

Surely you know that a total system replacement would be a big job, but have you ever thought about just how big? Sure, you know you will have to swap out the failing furnace, and you may as well replace the air conditioning unit while you’re in there, but that’s it, right?

Actually, there is a lot more to an HVAC system than just those two machines. Think about all the behind-the-scenes components and the little components that are often overlooked, such as:

  • Ducts – Keep in mind that your ducts are probably as old as that furnace you are replacing, and that a new, efficient unit cannot operate at nearly its full potential with faulty duct work.
  • Thermostats – Your old ones may not even be compatible with a new furnace or air conditioner.
  • Wiring – For the thermostat, among other things.
  • Insulation – Many homeowners forget that insulation is part of an HVAC system, too. Just like we said about duct work, old insulation does not help a new system achieve maximum performance.
  • Piping – Such as refrigerant piping on a geothermal system or a ductless air conditioning system.

You can see that the job starts to get pretty complex pretty fast. This doesn’t mean you should shy away from a necessary replacement, just make sure that you fully consider the scope of what you need done, as well as the budget and time frame you have to work with. If you have any questions about replacing your Southgate home’s HVAC system, give Baker & Sons AC a call today!

Essential Components of a Gibsonton Home Comfort System

Wednesday, December 21st, 2011

Indoor comfort is defined by several factors: temperature, humidity, and air quality. If any one of the three is out of the “normal” range it can affect the quality of life in your Gibsonton home.

The ultimate goal of any heating & cooling contractor is to ensure that customers are comfortable – meaning that all three factors are addressed when servicing, replacing, or installing new equipment in a home. This equipment includes furnaces and air conditioners but also extends to electronic filters, ultraviolet (UV) lighting, etc.

Obviously, the essential component for most U.S. households is a furnace. Air conditioners may not be essential for all parts of the U.S., namely the northern states, but are still considered an integral part of any home comfort system. Add-ons like electronic filters are important for controlling the air quality.

Let’s look at the furnace first. There are several choices but most can be found in two different classifications: single-stage or variable speed two-stage. Your choice depends on the indoor square footage, your own comfort needs, and possibly the cost of energy units (gas or electric for example). Forced air is a common method of moving heated air to all parts of the home via an air handling unit and through a duct system. But gaining in popularity is radiant heat (electric), which does not utilize a duct system.

Air conditioners also come in a variety of sizes, including window/room air conditioners or central air conditioning, which is likely a “split” system including an outdoor unit and indoor coil. The size of the air conditioner is determined by square footage, which is part of a load calculation performed by qualified heating & cooling contractors while planning the equipment replacement or new installation. An oversized air conditioner may produce high humidity levels and an undersized unit may not provide enough cooling to all areas of the home. High humidity levels contribute to higher indoor temperatures in the summer, and can also lead to respiratory problems.

If someone in your home has allergies or is sensitive to certain pollutants in the air, it may be important to include extra filtration in your heating & cooling system, such as electronic filtration and UV lighting mounted in the buildings duct system, to kill germs and contaminants.

And speaking of an essential component, duct systems are keys to maximizing efficiency and comfort. Properly sized, insulated, and sealed, the duct system is a key to comfortable, healthy indoor air – and energy efficiency. It is also important to keep your duct system clean, too.

As always, it is best to consult with a qualified and licensed heating and cooling contractor who can offer the best solutions for your home comfort system.

What is Refrigerant Pressure and Why Does it Matter? A Question from Samoset

Wednesday, November 16th, 2011

Refrigerant is often called the “lifeblood” of the mechanical cooling devices, such as refrigerators and air conditioners, that you have in your Samoset home.  The main function of refrigerant is to transfer heat through a closed loop system. Various heating and cooling (HVAC) components require different operating pressures to move refrigerant and process the “refrigeration cycle.”

In a nutshell, the refrigeration cycle involves refrigerant, which changes from a liquid to a vapor and back to a liquid again by the addition of pressure and heat. In a refrigeration system, pressurized refrigerant passed through an expansion valve into an evaporator and pressure is reduced. The evaporator is a tube which passes by the area to be cooled. When the pressure drops, this liquid refrigerant changes into a vapor, which absorbs vaporized heat from the area around the evaporator. After the heat is absorbed by the refrigerant, it flows to a condenser, where it passes over coils, absorbs heat from the hot vapor, and condenses back into a liquid. The liquid is returned to the compressor and the cycle begins again.

Today’s refrigerants – especially those used in residential applications – are broken down into two different types, labeled R-22 and R-410A. R-22 is made up of a chlorofluorocarbon (CFC) chemical, which has been found to be damaging to the Earth’s ozone layer. It has been replaced by R-410A, which is made up of a hydrofluorocarbon (HFC) chemical and will eventually be phased out by the year 2020. One of the biggest differences between the two are their operating temperatures. HFCs operate at much higher refrigerant pressure.

This change between refrigerants has created some interesting dynamics and challenges for the HVAC trade. Gauges used to check pressure readings have all changed. And mechanical compressors do not operate with a variety of refrigerants, so the compressors and coils need to be swapped out, too. To give you an example, let’s say you are shopping for a new central air conditioner. Chances are, the new air conditioner will run on R-410A. Your old air conditioner ran on R-22. In order to “match” the compressor in the your new air conditioning unit to the existing indoor coil, you will need to replace the coil and the lines running from your outdoor condensing unit to your indoor air handling unit, which is mounted to your furnace.

You don’t have to understand the refrigeration cycle to know that today’s high-pressure HFC refrigerants require different test instrumentation and retrofitted or upgraded mechanical equipment. The change in operating pressure is a small price to pay for a safer and “green” environment.

Happy Halloween Weekend (and Scary Air Conditioner Noises)

Friday, October 28th, 2011

Everyone at Baker & Sons Air Conditioning wishes you a Happy Halloween Weekend! Have a great time as a ghost, a goblin, or anything in between! And to make your Halloween a little less spooky, here is an explanation of the scary noises that sometimes come from your air conditioner.

If you notice excess noise coming from your air conditioner, it might be a problem that can be fixed by your technician. Here are some common causes of excess noise from an air conditioner and what you can do to fix them.

  • Blower – The blower is a motor and fan blade assembly. If the blade touches the housing or if the motor needs a tune up, it might start to make excess noise. Loose screws, foreign objects, or a need for oiling or new parts will all cause noise problems but they are all easy fixes.
  • Ductwork – If the sounds you’re hearing are in the ductwork or vents, it may be due to expansion and contraction in your ventilation system. This is normal and while it may be obnoxious, it tends not to persist during the hottest months as temperature won’t fluctuate as much.
  • Bubbling Sounds – If you hear a gurgly or bubbly noise coming from your indoor unit, it may be due to a blockage in the condensate line. The easiest solution is to clean the condensate line and check for any clogs or blockages in the system.
  • Clicking Sounds – If you hear a clicking sound, it is likely from the relay or contactor in the system. If this is the case, have a professional check it right away. Electrical problems are not to be taken lightly where your air conditioner is concerned.
  • Foreign Objects – Sometimes, the condenser fan will make a lot of loud noise because foreign objects get stuck in there. Sticks, leaves, toys, food from small animals – it can all get stuck in the fans and make a tremendous amount of noise. Keep the area around your condenser unit clear of debris and check it often if you hear loud noises.

Most noises from your central air conditioning unit are explainable and can be fixed relatively easily. If you cannot find the source of the noise, however, and it is only getting worse, call a professional before the problem grows.

Things to Check on Your Broken AC Before Calling a Sarasota Springs Professional

Wednesday, October 26th, 2011

A broken air conditioner is a stressful situation, especially since you’re considering whether you need a Sarasota Springs professional to come out. No one likes spending hundreds of dollars to have a professional take a look at their system, so before you call anyone, make sure to check these problems. You may be able to fix the problem on your own without spending a dime.

Thermostat

The thermostat is one of the most common problems you’ll have with an air conditioner.  Make sure the thermostat wasn’t knocked out of position and the sensors near your coils are in the right place. Often times, a bumped sensor or a slightly off thermostat can cause this kind of problem and as a result, you’ll be left without steady cooling.

Check Your Filters

Another common problem that can cause issues with your air conditioner is filter clogging. While the system will continue to run with a clogged filter, there are a few issues that might pop up – it could smell funny or you might notice icing on the outside line (a major problem). If you allow the filter to get so clogged as to block the air flow from your system, you can expect a number of problems to crop up.

Blower Belts

Check the system’s blower belt for damage like cracking, excess slack or general wear. A blower belt that isn’t properly installed or that needs to be replaced will reduce air flow which can result in ice buildup or poor air flow – it will make it harder for your system to maintain a steady temperature.

Check the Outdoor Unit

Check to make sure nothing is blocking the outdoor unit. Clean the condenser coils and remove any debris that might have built up around the outdoor unit. Often, slowed air flow is caused by nothing more than leaves piled in front of your condenser.

If none of these problems is the culprit or if you fix them all and your system continues to struggle, it is time to call a professional.

Things to Look for in a New Central Air Conditioning System in Apollo Beach

Monday, October 24th, 2011

When it comes time to buy a new air conditioner in Apollo Beach, there are a lot of factors to consider. Beyond the obvious issues like cost, you need to consider how that system will operate once installed. What factors are most important to you? Control? Comfort? Cost? Here are some things to consider when selecting your new air conditioner.

  • SEER – The Seasonal Energy Efficiency Rating measures the efficiency of your cooling system during a typical hour. To calculate this number, we divide the total BTUs of cooling produced by the watt/hours of electricity consumed during that hour. So, the higher your SEER rating, the less electricity is used to produce the same amount of cooling. Standard SEER ratings are between 11 and 15 these days, but some high end units have SEER ratings of up to 20.
  • Controls – How much control do you want of your system? Many air conditioners these days come with multiple speeds, allowing you to control the air flow as well as the amount of energy consumed by the device in cooling. Do you want it to constantly blow at 100% or would you like it to run at 50% to reduce consumption. Another option available in central air conditioners is zone control, allowing you to determine which rooms receive cooling with separate thermostat settings.
  • Dehumidification – Air conditioners are dehumidifiers by default, but not every system offers the same degree of humidity control. Some simply remove moisture as part of their regular operation. Others have more advanced controls to provide specific humidity control throughout the year.
  • Sound Dampening – Newer models have sound dampening features like insulation and vibration isolation to reduce sound. These are also great for weather protection and help to maintain your system for more years.
  • Refrigerants – Most new air conditioners now use the R410-A refrigerant which will be required in all new units starting in 2020, but there are some lower cost units still using R-22. Check to make sure you have the environmentally friendly coolant offered by newer models.

A good central air conditioner will keep your family cool and comfortable for years to come so make sure to do your research and choose a model that fits your needs in advance. If you’re not sure about any one feature, a professional installer can help you make your decision.
