Sealing Your Ductwork: What You Need to Know

March 23rd, 2016

Air ducts are a vital component of your home’s HVAC system, and any ducts that are leaking can reduce the performance of the system considerably, increasing your energy costs and making your home less comfortable. Properly sealing your ductwork is a relatively simple process, but there are a few things that you should know first.

Why a Proper Seal is Important

Leaking ductwork can allow up to 30 percent of the air moving through the system to be lost, increasing your heating and cooling bills by up to 40 percent. Additionally, leaks in the ductwork can allow dust, combustion gases from nearby appliances and other pollutants to enter the duct system and be carried throughout the house, reducing your indoor air quality. Properly sealing your ductwork can reduce your energy costs, especially if the ducts run through uninsulated spaces like the attic, basement or a crawl space, and it can improve your home’s indoor air quality.

How to Determine if You Have Leaks

A couple of the symptoms of leaky ductwork are high energy costs, inconsistent temperatures or rooms that are hard to keep heated or cooled. You can also inspect any ducts that are easily accessible and check for damaged tape or mastic at the joints, disconnected or loose joints, holes or other damage, and obvious air leaks. Often, however, the ductwork is hidden in walls or otherwise inaccessible, and you may need a professional to inspect it.

Sealing the Ductwork

Sealing your ductwork can be a difficult job, especially if it’s inaccessible, and it’s often best left to a professional. To do it properly, any loose joints need to be secured, using screws for rigid ducts or the proper clamps for flexible ducts, and each joint should be sealed with mastic or foil tape that is specially designed for HVAC systems. Despite the name, regular duct tape cannot do the job properly. Any holes or other damage should be patched, and kinks or twists in flexible ducts should be straightened.

How to Lower Heat Gain in Your Home

March 9th, 2016

When you turn on your air conditioner this summer, one of the last things you need is more heat in your home. Heat gain is a common source of additional indoor heat that comes from multiple natural and man-made sources. Not only will heat gain make your home less comfortable, it will also increase your monthly cooling costs as your air conditioner or heat pump works harder to compensate. Here are some ways to lower heat gain in your home and save money and energy while staying consistently cool.

  • Close the curtains and drapes: Heat gain through windows is probably the most common source. If you’ve ever seen your pet sleeping in a sunny area, you know that those spots of sunshine can be very warm. Excess sunshine can also raise indoor temperatures by a significant amount. To stop this source of heat gain, close your curtains and drapes during those times when there is likely to be a lot of sunshine coming through the windows.
  • Reconsider using heat-generating appliances: Cooking using stoves, ovens, and other appliances can produce significant amounts of heat gain. Consider using other methods of cooking during the hottest parts of the day, such as small toaster ovens or microwaves. Reserve the use of ovens and cooking stoves for early morning or late evening hours.
  • Run ventilation fans in the bathroom: Using hot water in the bathroom can produce both heat and moisture. When showering or bathing, make sure to turn on the ventilation fans in the bathroom to pull out moisture and heat that could otherwise get into your larger living spaces.
  • Insulate the attic: Attics can get extremely hot in summer, so make sure the attic spaces and roof are well insulated to reduce heat build-up in that area. Attic ventilation systems can also help remove hot air.

4 Signs Your Home Has Poor Indoor Air Quality

March 2nd, 2016

The quality of the air inside your home has a significant effect on both health and comfort. Here are some of the signs of poor indoor air quality you should be watching for. If you notice these signs, contact your local trusted HVAC professional for help.

1. Increased Discomfort or Health Problems

Poor indoor air quality can contribute to physical discomfort while also making some health problems worse.

  • Dust, pollen, mold, pet dander, and particulates in the air can trigger allergies or asthma attacks.
  • Particulates can irritate eyes, noses, and throats, causing unpleasant scratchy feelings.
  • Particulates can cause sneezing, coughing, watering eyes, and skin irritation.
  • In severe cases, poor indoor air quality can cause dizziness or nausea.

2. Increased Amounts of Dust

Take a look at the shelves and other surfaces in your home. If there is an increased amount of dust on these surfaces, it could indicate a problem with indoor air quality. More dust and particulates can be present in poor-quality air, and over time, this dust will settle on surfaces in your home. You may even see more dust floating through the air if it’s made visible in sunshine or other light sources.

3. Bad Odors

If you notice more bad odors than usual, or unpleasant smells that will not go away, you may have poor indoor air quality. Certain activities, such as cooking, may produce temporarily strong odors, but if the smells you’re noticing are frequent or consistent, it could indicate a reduction in indoor ventilation and a drop in indoor air quality.

4. Higher Humidity and Mold Growth

Higher humidity in your home could be an indicator of poor air quality. This is especially true if the increased humidity is also accompanied by more mold growth.

Sealing Air Leaks Will Save You Money

February 24th, 2016

Any gaps or leaks that allow conditioned air to escape your Florida home (or that allow unconditioned air to enter it) can reduce the efficiency of your heating and cooling system, leading to increased energy costs. By finding and sealing air leaks with these tips, you can save money and be more comfortable throughout the year.

Windows and Doors

Poorly-sealed windows and doors often feel drafty and can contribute significantly to higher energy costs. Use weatherstripping along the bottoms and tops of windows to seal gaps between the window and the frame, and use caulk to seal around the edges of the window frames, inside and out. Install weatherstripping around the inside of the door frame, where the door meets it, and use caulk around the edges of the frame. Install a door sweep to seal any gaps at the bottom of the door.

Attic

Warm air often escapes into the attic during heating season. Use caulk to seal around holes drilled for electrical lines, plumbing vents or lighting fixtures, or expanding foam if the gap is larger than ¼ inch. Seal around appliance flues and chimneys using high temperature caulk, and install a metal baffle to keep insulation away from any hot surfaces. Install baffles around recessed lighting, and seal soffits using caulk and insulation. Use unfaced insulation in plastic bags to seal any empty stud bays.

Exterior Walls

Any holes in the exterior walls can increase energy usage. Use caulk or expanding foam to seal holes drilled for plumbing, electric, or gas lines, as well as dryer vents or exhaust fan openings. Seal around any light fixtures, and repair or replace damaged siding. Use foam gaskets on interior outlets to seal the outlet covers.

Basement

Cool air often enters through the basement and is drawn into the rest of the home. Use caulk to seal around rim joists and the sill plate, as well as any holes drilled for plumbing or electric lines.

Attic Insulation: Common Myths & Misconceptions

February 17th, 2016

Properly insulating the attic in your Florida home is important to the overall efficiency of your HVAC system, but there are many myths and misconceptions about the process. Here is the truth behind some of the most prevalent attic insulation myths.

Insulating the Attic is Not Necessary in Warm Climates

Even in Southwest Florida, insulating the attic is important, as it prevents heat from escaping to the outside during the winter and prevents the hot air in the attic from warming your home during the summer. For the areas around Naples and Ft. Myers, the recommended insulation levels in the attic are from R-30 to R-60.

Insulating the Attic Will Seal Air Leaks

Attic insulation alone will not seal air leaks, though some types, such as sprayed foam, do a better job than others at sealing during the installation process. To properly seal the attic, there should be a separate vapor barrier installed if it is required in your area, and all holes drilled for electrical lines, plumbing vents, light fixtures and appliance flues should be sealed with caulk, expanding foam insulation, or for flues, chimneys and some recessed lighting fixtures, a combination of flashing and high-temperature caulk.

R-Value is Constant

R-Value is a measurement of a material’s resistance to the flow of heat, and it is assigned according to standard tests done in a lab. In actual use, the effective R-Value of an insulating material can vary based on many factors. Materials like fiberglass can increase or decrease in R-Value according to the temperature, and R-Value can be significantly reduced if the material becomes wet or is subjected to drafty conditions.

Insulating the Attic Automatically Increases HVAC Efficiency

Properly insulating your attic is only one factor in how efficiently your HVAC system operates. Some other examples include whether the HVAC system is sized properly, whether your ducts leak, how drafty your windows and doors are, and how many sources of heat gain are present, such as heat-generating appliances or windows without shades.

3 Ways to Alleviate Pet Allergies in the Home

February 3rd, 2016

Adding a pet to your household can be a very rewarding experience, both for your family and the pet itself. If one of your family members has pet allergies, however, dander from the pet may cause symptoms such as sneezing, runny nose, itchy eyes or other problems. In many cases, pet allergy symptoms can be significantly reduced by doing a few simple things around your home.

Maintain the HVAC System

Making sure that your HVAC system is clean and well-maintained can help reduce the amount of pet dander in the air dramatically. Have an HVAC professional perform routine maintenance on the system at least twice a year, including replacing the air filter and cleaning the blower fan, air handler and the evaporator coil thoroughly. Between visits, check the air filter yourself every month and replace it as necessary. Consider upgrading your air filter to one with a higher MERV rating to remove more particulates from the air, or consider installing a HEPA filter for the best protection.

Dust and Vacuum Often

Reduce the amount of pet dander and hair collecting in your home by dusting often with either electrostatic cloths or damp rags to catch all the small particles. Vacuum the entire home on a weekly basis at least using a machine with a HEPA filter, and eliminate clutter to reduce the amount of surfaces that collect dust and dander. Avoid installing carpeting, if possible, and take throw rugs outdoors once a month to clean them thoroughly.

Keep Bedding and Furniture Clean

If possible, try to keep pets out of the bedrooms of family members with pet allergies, and use hypoallergenic mattress covers, sheets and pillowcases in each room. Wash all bedding at least once a week. Vacuum upholstered furniture weekly, and consider installing furniture covers or throws that can easily be removed and washed to reduce pet dander accumulation.

Understanding Insulation R-Values for a Comfortable Home

January 27th, 2016

Your home heating and cooling system is your primary tool for keeping your home comfortable, but insulation is another factor that can have a significant effect on indoor comfort. The type of insulation you use in your home must be carefully chosen, and the insulation R-values must be appropriate for your geographical area. Here is a brief guide to insulation R-values and why they are important.

The Purpose of Insulation

Insulation prevents the flow of heat from warmer to colder areas. In a residential setting, insulation keeps warm air in during the cooler months and out during the hotter part of the year. Without insulation, or without enough insulation, heat from your furnace or heat pump escapes from your home in winter, while your air conditioner is overwhelmed with incoming heat during the summer. This makes your indoor spaces uncomfortable and increases the amount you pay for heating and cooling every month.

R-Values and Their Meaning

Insulation R-values indicate how effective a particular type of insulation will be at resisting the flow of heat. There are several types of insulation available to choose from, including fiberglass, cellulose, and foam. Each type of insulation will have an R-value, while better-quality insulation of each type will typically have a higher R-value. The higher the R-value, the better the insulation will be a resisting the flow of heat.

The R-value of insulation can also be affected by the thickness and density of the material, and whether or not the insulation material is compressed. Each layer of insulation is considered separately when calculating R-value, with the values of each layer added together to reach the final R-value rating.

In southern Florida, the U.S. Department of Energy recommends insulation with an R-value of R30 to R60 for attics, R13 to R15 for walls, and R16 to R19 for floors.

Conditioned Air serves heating and cooling customers in the Florida communities of Sarasota, Bradenton, Ft. Myers, and the surrounding areas. Contact us today for more information on insulation R-values and the benefits that proper insulation can have for your home.

Troubleshooting Hot and Cold Spots in Your Home

January 20th, 2016

Uneven temperatures in your Southwest Florida home are not only uncomfortable, but they may also indicate a problem with your HVAC system or the house itself. By troubleshooting hot and cold spots in your home, you can find the source of the problem and take steps to correct it.

Malfunctioning HVAC System

An improperly-sized or malfunctioning HVAC system can easily lead to hot or cold spots in your home. Make sure the air filter is not clogged or excessively dirty, and replace it if necessary. The air filter should last several months, but it is a good idea to check it at least once a month. Inspect both the indoor and outdoor coils of a heat pump or air conditioner. If the coils are dirty or clogged with debris, the system will not heat or cool properly, and they will need to be cleaned. If you have a furnace, make sure that the burners are free of dirt and soot to keep it heating efficiently. If the problems remain, have a professional inspect the system and make sure that it is sized properly.

Duct Problems

Blocked or leaking ducts can also cause uneven temperatures. Make sure all the vents are open, and check inside the ducts for obstructions and remove them, if possible. Inspect the outside of accessible ducts for cracks, holes, disconnected joints and missing or damaged insulation. If the ducts are leaking, missing insulation, excessively dirty or obstructed, have a professional repair them.

Drafts or Air Leaks

Hot or cold spots can be caused by air leaking into or out of your home. Seal drafty windows, doors, and any holes in the exterior walls with weatherstripping, caulk or expanding foam insulation, and make sure that your home is properly insulated.

Thermostat Problems

Make sure that your thermostat is working correctly, and replace it if necessary. Also, make sure that it is in a suitable location to get a correct reading, and not in a drafty or sunny spot.

Understanding MERV Ratings for Cleaner Air

January 13th, 2016

When choosing an air filter for your home heating or cooling system, you must be aware of the air cleaning and filtering capacity of the filter you choose. Filters have efficiency ratings that can help you determine which filter is best for your particular needs. These ratings, called MERV numbers, can tell you whether or not the filter will be able to remove particulates such as dust and pollen to clean your air to a suitable level. Here is a brief introduction to MERV ratings and what they mean.

The Meaning of MERV

MERV stands for Minimum Efficiency Reporting Value, which is a standard measure of air filter efficiency and performance. A filter’s MERV rating indicates how effective it is at capturing small airborne particulates as air circulates through your HVAC system. MERV ratings indicate a filter’s capacity to remove particulates between 0.3 and 10 microns in size.

Uses of MERV Filters

MERV ratings for filters used in most residential settings range from 1 to 16. There are filters available with MERV ratings of 17 to 20, but these are usually extremely high-quality filters that require specialized mountings. Higher-MERV filters are also thicker and more dense than lower-MERV models. Before using a high-MERV filter, you must be certain that your HVAC system has the airflow capacity to support it.

MERV Specifics

Lower-MERV filters are often very inexpensive, but their ability to filter your indoor air is limited.

  • MERV 1-4 filters are usually only good at collecting larger particles of 10 microns and above.
  • MERV 2-8 filters are medium-quality, and can remove particles of 3 microns and larger.
  • MERV 9-12 filters are considered high quality and can easily capture particulates of 1 micron and larger.
  • MERV 13-16 filters are the highest quality typically used in residential systems and work best at filtering out smaller particulates.

Conditioned Air provides professional, courteous HVAC sales, installation, and repair services for customers in Sarasota, Bradenton, Ft. Myers, and other communities in southwest Florida.

How UV Light Air Purifiers Keep You Breathing Easy

January 6th, 2016

Ultraviolet light has been used in hospitals for years to kill pathogens like bacteria and viruses as part of the sterilization process. By using a similar technique, a UV light air purifier can help to keep the air in your home healthier, which is especially useful in humid areas like Southwest Florida. There are three different types of UV light air purifiers, but they all function in a similar fashion.

 

UV Light Air Purifier Types

The most common UV-based air purifiers are:

  • Air handler-mounted purifiers: One or more UV lights is mounted inside the air handler cabinet, illuminating the filter, the evaporator coil and the interior surface of the air handler.
  • Duct-mounted purifiers: A special system including UV lights is mounted in the duct system, typically on the return side.
  • Standalone systems: These are self-contained air purifiers that can be used in any room, up to the rated capacity of the system.

How They Work

The UV light inside the air purifier shines on any microorganisms located on nearby surfaces or in the air stream, within a certain distance from the UV source. Any viruses, bacteria or other microorganisms that are exposed to the light for more than about half a second will have their RNA or DNA degraded by the UV light, killing them.

Certain types of UV-based air purifiers work better than others, because they allow the microorganisms to be exposed to the UV light for a longer period. Generally, air handler-based systems or well-designed standalone systems produce better air quality than a duct-mounted system, which sometimes has air moving too quickly to treat effectively. A properly-designed system, however, can overcome this.

UV light can also break down odors and volatile organic compounds, leaving the air fresh. Moreover, it can reduce A/C maintenance by keeping the evaporator coil cleaner and preventing algae growth that clogs the condensate drain.
