Yard Maintenance: Outdoor Unit Safety

You probably know that the outdoor component of your air conditioner, the condenser/compressor, is built to be sturdy and withstand the elements. More than likely, you give it little thought, expecting that the strong metal housing that surrounds it is sufficient protection against anything that can happen. Under most circumstances, this would be true. But condensers are damaged more often than you might think -- principally from careless practice during yard maintenance.Read on and learn how to improve your HVAC outdoor unit safety.

Tips for Maintaining Condenser Safety

Maintain a 2-foot clearing around the condenser.

Remove all grass, weeds and shrubbery within a 2-foot area so that the condenser can maintain good air flow. Trim back any overhanging limbs that might fall on the unit during a storm.

Create a weed-free layer of pebble rocks or stones around the concrete base of the condenser.

Add a plastic layer under the rocks or stones to inhibit weed growth. If weeds do take root, don't use a weed whacker to remove them, as these appliances can throw rocks into the fins hard enough to make a hole and even damage the coils. The purpose of the rock or stone bed is to inhibit the growth of weeds or grass around the condenser so that you don't have to mow or whack them, and so that the clippings don't end up in the fins or coils.

Point the mower away from the condenser.

Make sure that grass clippings are blown away from the condenser, as they can clog the fins or coils and affect air flow.

Don't cover the condenser.

Some homeowners cover the condensers to protect them from storms or flying debris, but sometimes, these covers cause more problems than they solve. A covered condenser can make a comfy home for vermin, and also may promote the growth of mold. If you're concerned about hail, it's best to erect a sturdy box or barrier around the unit that allows adequate air flow.

How New Steel and Aluminum Tariffs Affect the U.S. HVAC Industry

Tariffs on the steel industry have been all over the news. One side claims they're great, the other side says they're disastrous. You don't work in the steel industry, though. Do the tariffs still affect you? Yes. For one thing, steel tariffs are causing HVAC industry changes that affect homeowners everywhere.

Examining the Tariffs

The current administration has imposed a 25 percent tariff on steel from other countries and a 10 percent tariff on aluminum. Both materials are significant elements in the manufacture of HVAC systems, from furnaces to heat pumps to air conditioners.With steel and aluminum more expensive to obtain, the cost of manufacturing HVAC equipment is going up. If the manufacturers want to make money, they'll have to raise their prices. Many already have. That not only means that purchasing an HVAC system will become more expensive, but likely having yours repaired as well. If your unit needs a replacement part made of steel, the cost will be higher.The increases in price don't just apply to steel and aluminum products, either. Some HVAC manufacturers are raising their prices on all their products, regardless of their materials, simply to compensate for the volatility of the industry and the impact it's had on them across the board.

What Can You Do?

If the steel tariffs are making life more expensive for you, you can always contact your congressperson and/or senators to let them know how you feel about the situation. Aside from that, though, the best thing to do amid these HVAC industry changes is what you've always done: shop around for the best prices and the best value.Find a system that will last you a long time. Look for one with good energy efficiency, so that the money you save on power bills can offset the extra that you're paying to buy the unit. And keep it well-maintained, to avoid needing lots of repairs and replacement parts.

Ways to Hide Your Outdoor HVAC Unit Without Compromising Efficiency

The outdoor side of your HVAC system is essential to your comfort, but let's face it: it's not the most attractive feature of your landscaping scheme. Chances are, you find it ungainly, intrusive and downright ugly, and wish there were a way to hide it. Maybe it's even noisy, and spoils your efforts at outdoor entertaining with its annoying roar.

What can you do to lower the profile of your outdoor HVAC unit? We've got a few suggestions that can help.

Move it.

This can be rather an expensive solution but in some cases, you may want to consider relocating your HVAC unit to a less intrusive location. It's probably best to consider this step when you're ready to replace HVAC equipment. Your options will be limited -- you can only move it so far away from the home, but a different location may help you make it more obscure and satisfy your landscaping and entertainment needs.

Landscape around it.

Attractive landscaping around an HVAC unit is often the key to making it less prominent. Choose plants carefully. Don't plant bushes such as holly with stiff, poking leaves, nor plants that are likely to shed fiber, seeds or leaves that will clog up the unit's parts. Plant plants 2-3 feet away from the unit, and keep them trimmed back for easy access.

Hide it.

Decorative garden elements can hide the unit. For instance, erecting a trellis and growing vines such as clematis, Virginia creeper or morning glory will help. You might also plant climbing roses, but make sure the thorns are far enough away where they won't trouble the technician. A wall in front of the unit or a wall around it might be another solution. If you're not handy enough to build these structures, you may find a pre-fabricated model at a garden landscaping supply or online. If noise is an issue, make sure you purchase a structure that muffles the sound, but doesn't restrict air flow.

Name That Tune: What a Humming Air Conditioner Means

All air conditioners make noise as they run, mainly from the blower fans and the compressors. When the dominant sound is a humming air conditioner, odds are, something isn’t working as it should. The most common problems associated with the humming sound include:

Indoor Noises

• When you hear humming sounds from the air handler, it may be caused by a frozen motor. Some blower motors require periodic lubrication to keep their bearings turning smoothly. A lack of oil will seize the bearings and prevent the motor’s shaft from turning. It could conceivably run until it burns out.

• Humming from the breaker box. Whenever you hear humming sounds near the circuit breaker panel, suspect a serious electrical problem and turn off the noisy breaker. If you can’t identify which, turn off the main breaker and contact a licensed electrician immediately.

Outdoors

A humming sound is much more likely to originate in the outdoor condenser and it could be coming from:

• The compressor. This part does the heavy lifting in cooling systems and it could hum or buzz when it’s at the end of its lifetime. It could also indicate an electrical problem involving the compressor.Compressors sit on rubber isolation feet that can wear out or crack. Damaged feet can cause the compressor vibrations to amplify and cause humming sounds.

• Frozen coil. It might seem counterintuitive, but a humming air conditioner may have a frozen coil. Coils freeze when the refrigerant level is too low or they’re too dirty. A frozen coil can do serious damage to a heat pump or A/C should the compressor continue to run.

• Fan problems. The condenser uses a large fan to blow the heat off the hot refrigerant. There could be a problem with its motor or the fan blade, which could be loose or bent.

Whenever you hear a humming air conditioner and it’s not working as it should or the sound is isn’t part of its normal operation, contact the pros at Air Assurance to diagnose and fix it. We proudly provide HVAC services for Broken Arrow homeowners.

It's Time for Fall HVAC Maintenance! Here's What You Need to Know

Emergency repairs to your HVAC system are not only expensive, they are often very inconvenient. You may have to wait for hours on the hottest or coldest day of the year for a technician to have time to address the issue. No one can second guess all of the things that can go wrong with an appliance, but regular maintenance can often spare you many uncomfortable hours. Follow these basic steps for fall HVAC maintenance to minimize your frustrations.

Address basic housekeeping tasks first.

Visually inspect air filters monthly. Clean or replace them as necessary. Dirty air filters force the fan to work harder, draining energy and wearing out the motor. An added benefit of a clean filter is cleaner air, helping you breathe easier. Remove dirt and debris that has collected around the unit. Sweep, vacuum, or dust around the coils and exposed parts. Black stains around air registers can indicate dirty HVAC ductwork, poor air filter maintenance, or furnace malfunctions. Add weather stripping to doors and windows to eliminate cold drafts.

Check thermostats.

Adjust settings as dictated by the weather to ensure that the system maintains a comfortable temperature in the home. Install a programmable thermostat to automatically adjust temperatures during periods when the home is unoccupied to save energy and money. In colder months, set the temperature to 68 degrees during waking hours and as low as 60 degrees while sleeping.

Schedule a maintenance check.

An HVAC professional will inspect electrical connections to make sure they are secure and delivering the correct voltage and current for optimal performance. The technician will lubricate moving parts to eliminate friction in the motor and extend its life. The technician will also check fuel connections for dirt, damage, leaks, and safety hazards, as well as inspect the condensate drain to make sure it is not clogged.

When it's time for you to schedule fall HVAC maintenance, contact the NATE-certified professionals at Air Assurance. Be sure to ask about our Extended Service Protection Plan. Our team includes the largest full-service HVAC fleet in the Tulsa metropolitan area, making our customers comfortable for 30 years!

Bewildered About What Type of Furnace Filter to Choose? This Guide Can Help

Buying the right furnace filter can make a big difference. With all of the choices out there, it can be hard to make a proper decision. However when you take into account all of the factors that are important to you in regards to your family’s health, indoor air quality and cost, the choice becomes much easier.First you must consider the efficiency of your filter by looking at its minimum efficiency reporting value, or MERV rating. The MERV ranges from 1-20, with 1 being the cheapest and least restrictive to airflow and 20 being the most efficient, collecting 99.9 percent of all airborne particles.A low-MERV filter provides just enough protection to keep larger particles out of the furnace. These are cheaper to use but do little to improve air as they are solely to keep your HVAC unit dust free. A cost-effective MERV 4 filter allows for decent airflow and catches most large particles like dust and lint and are good if you’re not overly concerned with air quality.These filters may be fine if you don’t have allergies; however, if you are sensitive to airborne allergens, you may want to consider installing an electrostatic furnace filter with a MERV rating between 8-10 that will catch pollen, spores and dander. If someone in your family has low immunity, consider a high efficiency, pleated synthetic cotton filter with a MERV of 14 or higher. These can be removed and cleaned, catch bacteria, most smoke and can last up to six years, if properly maintained.  While they do cost more, they will save you money in health care costs.Whichever you do choose, remember that filers with higher MERV ratings require more attention and regular cleaning or replacement. While higher quality filters remove more particles, they also put more strain on your unit due to reduced airflow so it is advisable to contact a qualified HVAC technician before making a change.For more information on furnace filters and HVAC needs, contact Air Assurance, servicing the Tulsa Metropolitan region since 1985.Our goal is to help educate our customers in the Tulsa and Broken Arrow, Oklahoma area about energy and home comfort issues (specific to HVAC systems).
