Ways Rain Could Affect an HVAC System

Ways Rain Could Affect an HVAC SystemThe ways rain affects an HVAC system are mostly indirect. After all, the only outdoor portion of your heating/cooling system is the outside condenser coil and compressor unit of the air conditioner, typically situated just behind or to the side of the house. That component is designed and engineered resist normal rainfall. The remainder of the air conditioner and all of the furnace are indoors. Nevertheless, there are still some ways rain affects an HVAC system. It’s a good idea to be aware of them if water-related issues occur.

Flooded Condenser Unit

While the outside half of the central air conditioner is rain-resistant, it’s not designed to be submerged in water. Localized flooding due to unusually heavy rains can swamp residential areas with standing water. Generally speaking, if flood water exceeds a depth of 15 inches, it may damage internal electrical components including circuit boards and connectors inside the external condenser/compressor unit of the central A/C. Moving flood waters may also undermine the concrete pad on which the outdoor unit is mounted.

Wet Ductwork

Heavy rain can also inundate HVAC ductwork if it floods the crawl space under the house where system ductwork is often routed. Ductwork is typically not waterproof. Water entering the ducts may remain contained inside duct segments long after the flood itself has receded. This water will deteriorate ductwork as well as form an environment for toxic mold growth inside the ducts.

Roof leaks during rainfall can occur unnoticed in the attic for some time. Chronic leakage into the attic can seep into HVAC ductwork installed there. This ongoing moisture will rust and corrode ducts as well as trigger mold growth. Rain leakage into the attic also saturates attic insulation, severely reducing its insulating properties. Insulation compromised by moisture allows increased heat transfer into and out of the attic and causes your furnace and air conditioner to run longer cycles to compensate.

How Ceiling Fans Affect Your Home’s Energy Efficiency

How Ceiling Fans Affect Your Home's Energy EfficiencyIn Portland’s mild climate, your ceiling fan can do a lot to help you stay comfortable efficiently. To get the most out of your fan, keep these tips in mind:

A Little Help for Your Air Conditioner

On days that aren’t too hot, stick to using your ceiling fans for as long as you can before turning on your air conditioner. Once you do turn on the A/C, don’t turn off the ceiling fan. A ceiling fan can make you feel around 4 to 5 degrees cooler, allowing you to raise your air conditioner’s thermostat temperature by the same amount with no loss of comfort.

Every degree you raise your A/C temperature can cut your cooling bills by around 3 to 10 percent. Make sure the fan blades are set to spin counterclockwise as seen from below. Spinning in this direction, they blow a cooling breeze downward over your skin. If the blades aren’t set correctly, look for a small switch on the motor housing that lets you change their direction.

Comfort in Winter, Too

When the cool fall weather moves in, set your fan blades to spin clockwise and run the fan on the lowest speed. When spinning this way, the blades create an updraft that pulls cool air from the lower part of the room toward the ceiling. This air pushes the warm air near the ceiling out towards the walls and down to where you are. The warm air in your room will circulate around you rather than pooling near the ceiling.

Maximizing Your Fan’s Efficiency

Fans make you feel more comfortable, but they don’t change the air temperature so they don’t help when you’re not in the room. To save energy, turn off the fan when you leave the room.

To move air efficiently, your fan must be the right size for the room. For a room of less than 144 sq. ft., a 42-inch fan is enough. For a room of up to 225 sq. ft., choose a 50-inch fan.

Plumbing for Pet Owners: Do’s and Don’t’s

Plumbing for Pet Owners: Do's and Don't'sWhen you pet-proof your house, the plumbing is easy to overlook because most of it is hidden away where you’d think it would be safe. Pets and plumbing don’t always get along, though, so responsible pet owners plan ahead.

Do

Use drain strainers – These catch pet hair that ends up in the sink or shower before it enters the drain. Pet hair may be shorter than human hair, but it can still cause clogs. Even if you don’t bathe your dog or cat in a particular sink or shower, use a strainer there to catch hair that still finds its way in. Drain strainers also catch other clog-causing debris, so they’re a good idea all around.

Protect your pipes – As many surprised pet owners have discovered, some dogs, particularly as puppies, find plumbing pipes tempting to chew on. If you have exposed pipes under your sinks, keep the sink cabinets locked or protected with child safety latches. If that’s not possible and you’ve caught your dog gnawing on the pipes, apply a bitter-tasting chewing deterrent. Installing a cage around your pipes is another option if nothing else helps. Give your dog plenty of appropriate chew toys to keep his mouth busy.

Don’t

Flush kitty litter – This is a trap many pet owners fall into. Even the litters that claim to be flushable shouldn’t go down the toilet, and this is doubly true with clumping litters. Litter settles in the toilet’s P-trap where it swells up, traps debris, and will eventually cause a clog. It’s also not good for septic tanks. Even worse, cat feces can harbor the parasite toxoplasma gondii, which can survive wastewater treatment and end up in the water supply. Place used litter in a plastic bag and put it in the trash.

Let pets drink from the toilet – It’s usually not the germs in toilet water than can make your dog or cat sick, but the cleaning chemicals. For smaller pets, falling in is another risk. Keep your toilet lids closed and provide plenty of fresh water in bowls.

How Wi-Fi Detectors Can Catch Water Leaks and Freezes

How Wi-Fi Detectors Can Catch Water Leaks and FreezesWi-Fi detectors offer high-tech protection against a low-tech threat: water leaks and frozen pipes. A large portion of your household plumbing is typically routed through inconspicuous areas that don’t get much attention. If a leak occurs in a water supply line, major water damage can occur before the incident is noticed.

A cracked 1/2-inch supply line can release up to 50 gallons per minute, a flood which quickly migrates far and wide inside the house. Extreme damage to structure and valuable possessions continues until someone sees the problem and shuts off the main water shutoff valve. If you happen to be out of the house for the day — or worse, out of town for several days — when a pipe leaks or freezes and ruptures, the results could be catastrophic.

Water damage from plumbing leaks and frozen pipes is the second most common cause of homeowner’s insurance claims. Connected to your existing home router or wireless network, here’s how Wi-Fi detectors protect your house and possessions from severe water damage:

Leak Detection

Installed in areas where unseen water leaks are most likely to occur — basement, crawl space, laundry room, etc — a Wi-Fi detector senses the presence of leaked water. The wireless alert can trigger an audible alarm. The device can also send you a text or email wherever you may be to warn you of the hazard occurring at home. Some of the more sophisticated systems can even shut off the main household water valve if a leak is detected.

Freeze Protection

Ice forming inside a water supply line causes extreme pressure that can rupture the pipe. Exposed water lines in unheated zones of the house such as the crawl space are particularly vulnerable. A Wi-Fi freeze protection system features battery-powered wraparound sensors that can be installed on exposed supply lines in critical areas. When the pipe temperature drops below freezing, an alert is transmitted wirelessly and can sound an alarm as well as send you a text or email to inform you of the danger.

Yard Work and How it Can Affect Your HVAC System

Yard Work and How it Can Affect Your HVAC SystemIf the condensing unit for your central cooling system sits on the ground, doing yard work near it could reduce its efficiency. The condenser contains the fins and condensing coil that dissipate the heat that the refrigerant pulls out of your home. Any dirt and damage to these coils slows its ability to cool the refrigerant, which drives up cooling costs.

  • Lawn mowing. Cutting the grass around the outdoor condenser without a bag to catch the clippings can deposit small bits of grass on the fins and coils. Unless they’re removed, they’ll slow the cooling process.
  • String trimming weeds. The best way to avoid flying leaves and clippings around the condenser is to hand-pull the weeds or spray the weeds with herbicides while they’re still small.
  • Leaf blowing. If the leaf blower is strong enough, it could send sticks and twigs flying into the condenser’s coils. It’s a good idea to point the blower away from the condenser, or rake the immediate area instead of blowing it. Some central air conditioners drain the condensation they create outdoors using a drainpipe. It’s not uncommon when doing yard work for landscaping debris to blow into the end of the pipe that can block the water flowing from it.
  • Irrigation. Watering the yard doesn’t directly harm the condenser, but any over spray can if it hits the condenser. Besides the mineral deposits that can form on the fins and coil, continued exposure to water or moisture might cause rust on the condenser.

Solutions

  • One of the best ways to prevent clippings from sticking to the condenser is to xeriscape around the condensing unit. This type of landscape uses drought-tolerant plants that don’t shed many leaves and use a rock or crushed gravel ground cover.
  • Throwing a tarp over the condenser when you’re working around it will prevent some of the debris from lodging inside the fins and coils or bending them.

These tips will help you prevent damage to your condenser when doing yard work. To learn more about increasing cooling efficiency, contact Roth Heating & Cooling, providing HVAC services for Portland-area homeowners.

Consider These Things Before Adding a Home Addition

Consider These Things Before Adding a Home AdditionA home addition can give you the extra living space your family needs, increase your comfort and add to the enjoyment of your home. Whether you’re thinking of adding a new kitchen or family room, another bathroom or more bedrooms, there are a number of key factors to consider before you break ground.

Value, Budget and Financing

Building an addition is a costly undertaking, so make sure that the space you’re adding will truly serve your needs and that it’s a wise investment for where your home is located. Then, ensure that the proposed project fits within your budget, and plan how you’ll obtain financing if necessary.

Layout and Design

Work with an architect or designer to come up with a layout that makes the most of the added space and incorporates all your desired features and amenities. While the interior details are critically important, it’s also essential that the finished addition matches the style and aesthetic of your home’s exterior.

Heating and Cooling

Talk to an experienced HVAC contractor to determine the best way to heat and cool the living space you plan to add. A knowledgeable HVAC pro can assess your existing system and advise you if your current equipment has enough capacity, if the ductwork can be extended, or whether you’ll need to upgrade the components or install ductless units to serve the addition.

Electrical and Plumbing

You should consult licensed professionals about how the addition can be integrated into your home’s plumbing and electrical systems. You need to know whether there’s enough capacity to add extra breakers in your electrical panel, or how extending the plumbing system to serve new fixtures will impact water heating and water pressure throughout your home.

Choosing Contractors

Who you hire directly affects the success of your addition project, whether everything goes smoothly and if you experience future problems. Make sure that each contractor you choose is well-established with a good reputation, fully licensed and properly insured.

If you’re planning a new home addition and need expert plumbing, electrical and HVAC services, contact the Portland-area comfort pros at Roth Heating & Cooling, Plumbing & Electrical.

DIY vs. Handyman vs. Qualified Electrician

DIY vs. Handyman vs. Qualified ElectricianWe’re always looking for ways to save money on home repairs, but when it involves your electrical system, you should never cut corners. So if you’re weighing the wisdom of doing it yourself vs. hiring a handyman vs. hiring a qualified electrician, it’s usually best to go for the latter.

Hiring a Professional Electrician

While you or an amateur handyman with a good understanding of electricity may certainly do minor tasks, including reconnecting loose wires on a thermostat or perhaps even installing an electrical switch, doorbell or ceiling fan, it’s best to leave installation of electrical systems to the pros.

Electrical work is regulated by electrical codes. A building permit is usually required from the local municipality. Trained, certified professionals who adhere to current codes should be hired to work with plans approved by a city building code officer. An electrical inspector generally must sign off on major electrical jobs.

For more information, or to schedule an appointment with a certified electrician, contact Roth Heating & Cooling, Plumbing & Electrical of Portland today.

Why it Pays to Invest in Preventive Maintenance

Why it Pays to Invest in Preventive MaintenanceOf all the appliances in your home, your HVAC system is probably the most complicated and expensive. It also requires periodic preventive maintenance to run efficiently and dependably.

The benefits of professional attention far outweigh its cost, like:

  • Lower energy bills. Cooling and heating your home use about half your energy budget, and having your equipment professionally serviced helps lower energy use. When a system is cleaned, adjusted and lubricated, it doesn’t have to work as hard to keep your home comfortable. The goal of the HVAC tuneup is to bring the system back as closely as the technician can to its original factory settings.
  • Longer system lifetime. Everything mechanical wears with use, but keeping the parts clean goes a long way toward increasing their useful life. Over time, electrical parts corrode and when they do, the flow of electricity slows and heat builds. Dust on the components inside heating and cooling systems slows the heat exchange process. Your system has to run longer, which wears the parts prematurely.
  • Greater dependability. When a HVAC pro goes through your system during a preventive maintenance visit, he or she may find a part that’s not functioning as well as it should. Replacing a small part before it fails keeps your system running dependably especially during weather extremes.
  • Fewer repair costs. A failing part can have a damaging ripple effect throughout the system, and instead of needing to replace just one part, you may need to replace several others.
  • Maintain a valid warranty. Some manufacturers require periodic maintenance performed by an HVAC pro to keep the warranty active. Considering the cost of parts and labor, losing this protection could cost a good deal.

The best way to achieve the highest performance your system can provide is through routine preventive maintenance. For more information, contact Roth Heating & Cooling, providing trusted HVAC services for Portland-area homeowners.

Tankless Water Heaters in Your House: Pros and Cons

Tankless Water Heaters in Your House: Pros and ConsIf your older storage tank water heater is getting close to retirement age, you may be wondering if it’s worth going tankless. To help you decide, it’s good to learn the pros and cons of this type of water heater. The first pro of switching to a tankless water heater is the range of options it gives you. You can choose between gas-fired and electric models, and select a size ranging from a small unit to serve a single bathroom, or a large, whole-house model that’s capable of supplying three showers simultaneously.

Additional Benefits of Tankless Water Heaters

Making the switch to tankless water heating offers a number of other benefits:

  • Energy savings. Because there’s no tank of water that needs to be kept hot and ready for use, you can expect to see a drop in your household energy consumption and utility bills.
  • Long-term reliability. Storage tank water heaters typically wear out after 10 –13 years. As they age, the risk of a catastrophic tank failure and significant water damage increases. In contrast, tankless units have an expected service life of roughly 20 years, and there’s no tank that can suddenly fail.
  • Greater convenience. In the busy mornings and any other times when hot water is in greater demand, it’s easy to run out when you have a storage tank water heater. When you have on-demand units installed that match your peak household usage, you’ll assured of a continuous supply whenever hot water is needed.
  • Placement choices. Tankless units take up little room and are often wall mounted. The only restrictions on where you can place one are access to your gas line and the need for outdoor venting.

Potential Cons of Going Tankless

Tankless water heaters can cost two to three times as much as storage tank units, and the installation can cost more if your gas service needs upgrading. However, the reliability, convenience and energy savings you’ll gain can make the extra expense worthwhile.

For personalized advice about whether a tankless water heater is the ideal choice for your Portland-area home, contact us at Roth Heating & Cooling.

Ways to Decide if You Should Get a Plumbing Upgrade

Ways to Decide if You Should Get a Plumbing UpgradeYour plumbing is a vital household system that may not get a lot of attention until age-related problems begin to develop. If you don’t have the problems identified and addressed, you can end up dealing with costly water damage to your home. Learning how to recognize the warning signs of plumbing deterioration gives you an opportunity to get professional advice about whether a plumbing upgrade is needed before extensive damage occurs.

Ways to Tell You Have Problematic Plumbing

If you can relate to one or more of the following plumbing issues, it’s wise to have a licensed plumber inspect your system to help you decide if an upgrade is warranted.

  • Galvanized piping. If your home still has galvanized piping, you may not realize that it can be badly corroded on the inside even though it appears to be in good shape because the outside is treated against corrosion. If you start to experience issues with low pressure and frequent clogs, corroded plumbing pipes may be the cause.
  • Mixed materials. If a portion of your galvanized piping was replaced with copper and dielectric unions weren’t used between the two materials, your system can deteriorate faster than expected due to metal incompatibility.
  • Advancing age. The useful lifespan of residential plumbing system components is typically about 60 years. If your home is approaching that age, you have a chance to avoid extensive problems or damage by having the system assessed and replaced if it’s advisable.
  • Evidence of decay. You can tell a lot about the condition of your plumbing system by doing periodic checks on any pipes that you can easily access. Check the pipes coming off the water heater, running to the kitchen and bathroom sinks, or lines situated in unfinished spaces like the garage. Look for discoloration, dimpling or flaking metal, and fresh or dried water stains on adjacent surfaces. An increase in minor leaks and/or rusty-looking, discolored water coming from the faucets are other signs of deteriorated plumbing. Evidence of decay is not always easy to spot by the untrained eye.
