High Humidity

Here in the Deep South North Mississippi, West Tennessee, and North Alabama. We deal with moisture in crawlspaces. We find many homes that leave there foundation vents open year round. As a result high humidity finds the way inside the crawl space. 

When your heating and air duct or equipment is installed inside the crawl space. The temperature of the air is being delivered thru the duct work is around 45 to 55 degrees. When that mix’s with the warm 100% plus humid air then condensation is the end result. Some homes have drainage issues and or rain water run off goes under the foundation walls and the moisture starts to mix with warm humid air. Either way it results in mildew growing in the crawl space. Which will result to heavy mold if nothing is done to stop the issue. 

To correct the issue you have to do 3 very important things:

Install a Moisture Barrier

Installing a plastic moisture barrier (minimum of 6 Mill thickness) will lay on the ground. First you need to clean any debris from crawl space. Then lay the material down on the surface. Roll the plastic up the wall a good 12”. Also cut around each foundation piers. Roll the plastic up 12” as well. Then foam the plastic to the walls and piers to keep moisture from seeping up moisture barrier.

Install a WHOLE House Dehumidifier

We used to tell our customers to go to your favorite big box store. And purchase a 65 pint dehumidifier. They are like window units they brake a lot. So now we rely on a Honeywell DR65. This is a whole house machine that goes in the crawl space and suspends from the floor joist. We duct the system to each end of the crawl space to warm and dry up the moist areas. We install an independent drain line either in the sewer line or outside away from the foundation.

Sealing Your Duct Work

Once that you have done step 1 and 2 then you are ready to seal your duct work. There are 2 rules of thinking around this. You can seal the duct work by removing the duct wrap insulation and painting the seams with a liquid mastic. And then install new Duct wrap insulation around each duct. Some customers decide to replace the entire duct system and seal it completely while installing the new duct work.

Germicidal U.V. Light Technology can cure your Sickness

We have had a national record with flu virus cases this season. Most homes have been built tighter. They have house wrap on the decking of the house, better Insullation in the walls and attic. These are great ways to make the home energy efficient.  It also makes the home more dusty, and cannot escapethe germs out of the home.  

The Department of Energy (DOE) reports that most families stay in their home 60 percent more than ever before. More kids are staying inside to play video games and other inside activities.

Install a Germicidal Ultra violet light in your duct system will kill the mold, mildew, unseen bacterial,and many more flue germs, and viruses floating in the air.  The Germicidal Ultraviolet lights are simple to install, and work immediately killing the germs in your home. Some people never have sinus issues again, and someare greatly reduced.

5 Ways To Control Summer Allergies from The Harbin Heating and Air Conditioning

Efforts to control summer allergies begin at home. That’s because the inside of your own residence is where you’re most likely to get the most concentrated dose of airborne allergens. Some are outdoor microorganisms like mold spores and bacteria that infiltrate by the millions every time an exterior door is opened. Other allergens, such as dust, dust mites and pet dander, originate inside your home. The Environmental Protection Agency reports that your home may be 100 times more polluted with allergy-triggering airborne contaminants than the outdoors.

To effectively control summer allergies, remove outdoor allergens that find their way inside, and limit the sources of indoor allergens. Here are some ways to accomplish both:

Dust is composed mostly of human skin flakes, fibers from clothing, carpeting and drapes and tiny dirt particles. Keep dust out of the air by removing it with regular vacuuming, mopping and dust-wiping.
Kill dust mites by washing sheets, spreads and blankets once a week in water hotter than 130 degrees. Consider adding allergy-proof mattress covers to control dust mites, too.
Change your air conditioning filter regularly. A fresh filter cleanses the air of particulates. A dirty filter not only underperforms, but also becomes a breeding ground for living microorganisms that are trapped inside the filter media.
Consider installing a whole-house dehumidifier to treat all the air in your home. Maintaining interior humidity below 50 percent prevents the multiplication of microorganisms such as mold spores and dust mites. It also makes your air conditioner work more effectively.
Ask your HVAC contractor about a whole-house air purification system. Unlike portable room air cleaners, these units mount directly inside your ducts or air handler and remove over 99 percent of airborne particulates. Because your home’s entire air volume circulates through the ducts many times daily, a whole-house solution ensures total air filtration.
Since 1988, Harbin Heating and Air Conditioning Inc.  has provided Corinth Ms, Savannah Tn, Iuka Ms, Selmer Tn, Cherokee Al, and in between residents with cool comfort and healthy indoor air quality. Call us for more ways to control summer allergies with advanced air-purification technology.

ROI With A Quality Air Conditioning Installation

With A Quality Air Conditioning Installation, You’ll Maximize ROI from The Harbin Heating and AirHome Comfort Blog

With A Quality Air Conditioning Installation, You’ll Maximize ROI
A quality air conditioning installation involves much more than selecting the right equipment and using an expert contractor. A quality air conditioning installation involves many steps, and if your contractor doesn’t follow them, your system won’t perform to your expectations.

These are key elements of a quality air conditioning installation:

Sizing: Sizing your system correctly is paramount to performance. A system that’s too large will cost you more to purchase, and it will cycle on and off too frequently, placing stress on the internal components and decreasing the system’s life span. To size the equipment, your contractor should use the industry-standard method, Manual J.
Ductwork: Leaky ducts will contribute to poor comfort and energy loss. Your contractor should evaluate your entire duct system, identify leaks and then address problematic areas by using mastic or aerosol-based sealant or metal tape to seal the ducts.
Refrigerant: Having the correct refrigerant charge is also vital to performance. An incorrect charge will increase the operating pressure on the compressor, reduce efficiency by up to 20 percent and lead to expensive repairs. Therefore, verifying the refrigerant charge should be part of a quality air conditioning installation.
Airflow: The final factor that will ensure a quality installation, airflow must be set to the correct level, corresponding to the capacity of the A/C and the size of your ductwork. Your contractor should test the airflow, making adjustments as necessary.
As further proof of how important a quality installation is, Energy Star estimates that when these four factors are optimized, a system can operate at nearly 100 percent capacity. But failing to take them into account can lower your system’s cooling capacity by more than 25 percent.

The next time you buy HVAC equipment, make sure your contractor installs it correctly. You’ll maximize your return on investment and ensure that your system will keep your home cool.

A/C Operating Tips For A/C Operating Tips For Miss, Alabama, and Tenn homeowners

High temperatures are common in The Tristates throughout the year. But given the searing heat and stifling humidity of summertime, many homeowners run their air conditioners practically all the time. This can lead to very high utility bills. You may wonder what you can do to take charge of your energy costs without sacrificing your comfort. And it is possible. By following a few simple A/C operating tips, you can save money and stay comfortable, even in the Tristate areas.

Tristate area A/C Operating Tips

First, you need to keep your air conditioner in top shape. You should have your contractor tune up your A/C at the start of the cooling season. You can do your part by:

Changing the filter regularly. Put a new one in as soon as the old one looks dirty.
Ensuring that the outdoor unit is free of grass, dirt, dead leaves and other debris that can hinder airflow.
Removing any clogs or obstructions in the base drain pan. Also take steps to prevent mold growth in the drain pan.
Keeping ducts, vents and registers free of obstructions
Sealing and insulating all exposed ducts and finding and fixing exterior air leaks
Boosting the insulation in your attic, which will keep the heat from radiating through your ceiling
Reduce home heat gain

You can take additional measures to keep the air in your home cool and prevent heat gain. This will serve to ease your air conditioner’s workload.

Use thick drapes or blinds over large windows to keep out the heat from the sun. Consider drapes with a white or reflective backing. Alternatively, consider interior shutters, such as plantation shutters.
Do not turn on the oven on very hot days; instead, use your microwave.
Keep your use of incandescent lights minimal. They produce heat. Use compact fluorescent light bulbs instead.

R-22 Refrigerant Shortages Could Impact Your Comfort This Year: Get Expert Advice On How To Navigate Upgrades

Here in the Mississippi, Tennessee, and Alabama, where we use our cooling systems most of the year, you should know about an important change in the kind of refrigerant you’ll be able to use in your air conditioner. The R-22 refrigerant that your A/C is probably using now is being phased out of production. Expect prices to climb and availability to fall as this phaseout progresses.

Actually, this is not a new development. An international agreement called the Montreal Protocol in 1987 established a phaseout of chlorofluorocarbons, which harm the Earth’s ozone layer. Over the following years, the protocol was modified and amended. A modification in 1992 established a phaseout of hydrochlorofluorocarbons. HCFC-22 is also known as R-22. One of its brand names is Freon. The U.S. is enforcing the protocol through the Clean Air Act, and the phaseout is scheduled to be almost entirely in force by 2020.

What does this mean if you own an air conditioner that uses R-22? There could be R-22 refrigerant shortages and R-22 prices are expected to double or triple, so the cost of maintaining your air conditioner could go up. You don’t have to run out and buy a new air conditioner, but you might want to consider doing just that. Why?

If you have an older air conditioner, it’s probably much less energy efficient than today’s models. A new model will help you hold down your energy costs.
You’ll know you’re helping the environment by making your carbon footprint smaller. Your new air conditioner will use an environmentally healthier R-410a.
If you really can’t afford to replace your air conditioner at the moment, make sure you schedule timely maintenance. Maintenance will help you avoid costly leaks and the need to replace your refrigerant. And schedule that maintenance sooner, rather than later, as the cost of R-22 will keep rising.

At Harbin Heating and Air, we can help make the right decision for your unique situation. Serving The Mississippi,Tennessee, and Alabama, we maintain cooling systems and sell a range of air conditioners. Give us a call or visit our website.

Heat Gain: How It Undermines Your Hardworking A/C

The air conditioner in your Northern Mississippi and South west Tennessee home has been designed to keep you cool as efficiently as possible on the hottest summer days, but its job is often made much harder by heat gain, which can be caused by the sun, appliances that produce heat, and poor insulation in the home’s ceilings, floors, walls and attic. With the following tips, you will learn how to reduce heat gain in your home, which will help lower your utility bills and keep you more comfortable throughout the summer:

Shade Your Windows: Use awnings, curtains, blinds or shades to shade the windows and reflect the sun’s heat back outside during the day. Choose light-colored window treatments for the best reflectivity and look for products that have a low shading coefficient, which indicates how much shade a window treatment provides. Reducing solar heat gain alone can reduce your cooling bills by up to 25 percent.

Avoid Using Unnecessary Lights and Appliances: During the daytime, shut off any lights, appliances and electronics that you are not using, as they can produce extra heat. Use heat-producing appliances such as hair dryers, clothes dryers and dishwashers at night when it’s cooler and make sure to turn on the exhaust fans when cooking or bathing to remove excess humidity.

Check Your Insulation Levels: Make sure your home has adequate insulation to prevent heat gain. Ceilings and attic floors should have at least R-30, walls should have at least R-13, and floors should have at least R-19. Add more if necessary.

Seal Air Leaks: Use caulk, weatherstripping and expanding foam insulation to seal air leaks around doors, windows, damaged siding, plumbing runs and electrical lines outside and inside the home. Use door sweeps to seal the bottom of doors and foam gaskets to seal electrical outlets and switches.

Use Light Exterior Colors: Choose lighter-colored exterior paints, siding and doors when possible to reduce the absorption of heat from the sun.
