white mouse chewing on wire

Tips to Prevent Rodents from Entering Your Home

Rats and mice chewing away at your electrical wires, in your home, may sound like a horror movie, right? Unfortunately, it is a scary reality for homeowners in the Pacific Northwest.

Our climate, offers so many beautiful things for us to enjoy. However, it also offers opportunities for rodents to enter our homes, and garages, creating havoc on wiring and electrical panels.

Since rodents are nocturnal, you may not notice their presence immediately. Even when you do, it’s not always easy to tell if the mice and rats are chewing on the wires in your home.

Mice and rats usually target wires and chords, that are located in places where they can hide easily. This makes it more difficult, but not impossible, to spot the damage before you start to see its effects. Even if you haven’t seen any rodents in the flesh inside your home, there are numerous signs that can alert you to their presence. 

Rodents chewing on electrical wiring can present major safety problems and should be looked at by a professional as soon as possible. In the absence of electrical issues, a rodent infestation can still cause serious damage, that is both costly and difficult to repair.

Here are few tips to help keep those pesky irritants out of your house and garage:

Steel Wool

If you want to keep mice out of your house, bring on the steel wool. Unlike insulation, paper, or even drywall, mice can’t chew through steel wool.  Place the steel wool in any holes where mice may be getting in. 


If you have a hole in your wall that steel wool won’t fill, place a brick in front of it instead. Bricks are heavy and dense enough to prevent them from getting in. 

Caulk Any Small Holes

Mice can squeeze into virtually any space, so to keep them out use a little silicone caulk to seal entry points.

Use Moth Balls

Those strong scented moth balls can scare away mice and other rodents, too. Set out a few where you think the critters may be getting into your home. Hopefully they will run to the hills, and not your home.

Check Under The Hood Of Your Car In The Garage.

Unfortunately, with many people working from home due to the Coronavirus Pandemic- Many cars are going unused for prolonged periods of time. It’s never been easier  for rodents to find opportunities to nest inside cars, and that brings them one step closer to your house!

Keep Your Garage Food-Free

Don’t treat your garage like a makeshift pantry. Garages are often an entry point for rodents. Serving them up a buffet , can lead to infestation. Keep your food indoors!

If you think your electrical panel has been affected by rodents , give us a call and we can help you. In the meantime, hopefully the helpful tips will prevent the fury foes from entering your home!

galvanized pipes

Does Your Home Have Galvanized Plumbing?

Do you own or live in a house that was built before the 1960’s? If your answer is yes, then there is an excellent chance that your home’s plumbing has galvanized plumbing unless there has been an upgrade within the last forty-five to fifty years.

Replacement : When and Why

The lifespan of galvanized pipes are no longer more than fifty years, and since they have not been utilized since the 1960’s, they have already passed their expected lifetime. If you have any galvanized pipes within or outside of your residency, then you need to have them checked and replaced as soon as possible by qualified professionals.

Galvanized steel pipes were covered with Zinc to help keep the product from deteriorating, but with time they start crumbling from within, due to the rust and calcium build-up that begins to form, making the inside width of the pipe smaller. The more the rust and particles collect within the piping, the less room there is for water movement. With the decrease in water flow, it helps to increase the chances of having the piping leak or break from the pressure that can build up behind the water outlets. When you have pressure built up, you can then end up with water damage that can be very costly for the clean-up. If it is anywhere near the foundation it can compromise the foundation.

Other signs that you have problems with galvanized pipes are rust or brown colored running water after the outlets have not been in use for a while, decreased water pressure, rusting on the outside of the pipes or at the joints.

What do galvanized pipes look like?

When first installed, galvanized pipes looks similar to a nickel in color. But as it ages, galvanized pipe may appear much duller, lighter, or darker, depending on its environment. We’ve also seen homes where the water pipes have been painted, so it can be difficult to tell at first glance.

Health Concerns 

Recent studies have shown that galvanized pipe can leach lead into a plumbing system. It comes from the zinc coating on the inside  of the pipes. There is no safe level lead exposure.

Children are especially vulnerable to lead poisoning and can be affected even with low levels of exposure. Studies have found that some children are vulnerable to impaired vision, poor hearing, and headaches. Adults can also be affected by long term exposure. Studies showed that some adults may exhibit high blood pressure, painful muscles and joints, and disruption of the digestive system.

Risk of property damage

Leaks can occur without warning. Small undetected leaks, or large fissures, which can flood a room in minutes. 

Sediments from the rusting pipes, can clog faucets, shower valves, dishwashers, and other plumbing fixtures and appliances. This may result in either costly repairs, or even replacements.

Water can be restricted in areas where the pipes are reduced in size due to rust accumulation .

“Spot fixing” or partial replacement, though it may be necessary for a quick fix, is not recommended as a long term strategy. It is far more costly to replace pipes as needed, than to replace them all at once.If you do find that your home has galvanized pipes, your insurance may not cover any problems that could appear, due to the age of the pipelines. So it is advisable to have your plumbing evaluated before it is too late.

The Toilet Lid Is There For a Reason!

Leaving the Seat Up Can Create a Cloud of Particles

Leaving the toilet seat up or down has played a part in the battle of the sexes for ages, but with the Covid-19 pandemic the debate has become more serious. A new computer modeling study shows how a flushing toilet can send a cloud of little particles containing fecal matter into the air — fecal matter that could carry coronavirus.

Doctors have shown that coronavirus can live and replicate in the digestive system, and evidence of the virus has been found in human waste.”

Toilet Lids Help Keep Your Bathroom Clean

Toilets sold for use in your home feature a lid on the seat. Most people would concede that the toilet simply looks better when the seat and lid are closed, (which is why manufacturers photograph them this way!) Ease of use, habit and gender tend to guide your lid preferences. But those lids are actually an important part of reducing the spread of bacteria and were designed to help keep your bathroom clean.

While low flow toilets have greatly reduced this issue, every time you flush a toilet, germs can spread through the bathroom through micro-particles escaping into the air. This is not good news for your otherwise clean and shiny bathroom. You want the bathroom to be an environment of relaxation and respite and to accomplish this, cleanliness really counts. Calming showers and luxurious baths are high points in our day but thoughts of germs can be somewhat deflating.

Close the Lid- Every Time You Flush!

Luckily there is an easy fix for this issue; simply close the lid…every time! The lid was designed to keep germs where they belong, in the bowl and down the drain! If you leave the lid up when you flush, those germs can float around your bathroom, landing on any available surface, including towels, hairbrushes or even toothbrushes. Nobody wants that!

This easy fix not only works, but it also puts an end to the battle of up or down. You want it down…all the way, every time you flush.

tankless water heater

Are tankless water heaters for you?

Tankless water heaters, also known as on-demand or instant water heaters, have many advantages over traditional tank-style water heaters and can be an excellent long-term investment. However, like any product, they have their downsides and they are not the right solution for every home.

Unlike traditional tank-style water heaters, which continuously use energy to maintain a hot water supply, tankless water heaters only expend energy when you turn on a hot water tap or when you’re using appliances.

This on-demand style of operation results in their most significant advantage; energy and cost savings.

Besides energy and cost savings, there are several other reasons to choose a tankless water heater over a traditional tank-style heater. Tankless water heaters produce an endless supply of hot water, take up less space, have a lower risk of leaking, are safer, and have a significantly longer lifespan on average.

Long-term Energy and Cost Savings

The main advantage of tankless water heaters is that they are energy efficient and save you money over the long term.

A tank-style water heater expends energy around the clock to maintain the temperature of a 40 to 50-gallon water supply so that hot water is ready when it’s needed. Tankless water heaters, as their name suggests, heat water on-demand and do not maintain a supply of water. By only heating water when it’s needed, tankless water heaters do not experience standby heat loss, which occurs when heat escapes the water tank and needs constant reheating.

When a tap, shower, or appliance is turned on, cold water passes through the tankless water heater where it’s heated by either a gas-fired burner or electric coils.

Once the water is heated (this happens in seconds), the hot water travels through the pipes and out the tap, showerhead, or any other outlet in your home.

How much energy will you save?

Your energy savings depends on the amount of water you use and the efficiency of your previous tank-style system.

According to the U.S. Department of Energy, tankless water heaters can be between 8% and 50% more energy-efficient than tank-style water heaters, but the actual efficiency depends on the amount of hot water you use.

Switching from a tank-style water heater to a tankless water heater will save a family of four an average of $100 per year or over $1500 However, as long as your water usage at any given time is below the maximum allowable flow rate, tankless water heaters provide an endless supply of hot water. If space in your home is limited, tankless water heaters provide a huge benefit. They are usually mounted to the wall and take up significantly less physical space compared to tank-style water heaters.

What is the size comparison?

To give you an idea of how tankless and tank-style water heaters compare in terms of size, the average 40 to 50-gallon tank-style heater is 54 to 60 inches tall with a 20-inch diameter and is shaped like a cylinder.

The average tankless unit is around 27 inches tall, 18 inches wide, 10 inches deep, and rectangular.

Tank-style heaters take up floor space, usually in the basement, while tankless units are mounted to a wall like a circuit breaker and can fit in most closets.

Life Expectancy of Over 20 Years

If you’re already in your “forever home” or plan to stay where you are for a while, investing in a tankless water heater might be the right decision for you.

main water shut off valve

Portland Homeowners: About Your Main Water Valve

Where is your main water valve?

In most instances the main water valve is located within the footprint of the house, and on the same side as the water meter. However, it can also be located in a crawlspace or outside buried in a box.

Does your water valve work?

You can test to see if your water valve is working by closing the valve and checking a faucet. If the water comes out of the faucet with pressure, then your valve does not work and should be replaced.

The valve at your water meter DOES NOT COUNT. Code requires an accessible valve near or in the house. The valve at the meter is for servicing the meter only.

Water valve is essential!

Your main water valve is essential to keeping your home safe and from damage. You would not tolerate an electrical breaker that does not work. Making sure that you know where your main water valve is located, and checking to see if the valve is operating properly, is just as important for keeping your home safe.

Can’t find your valve? Not sure how it works? Does it leak when you turn it on?

Green Box Mechanical is here to help. Call us today and let us help you keep your home safe!

HVAC unit outside brick home

5 Signs You Need a New HVAC System

Increased Running Time

When your system gets old and requires a replacement, you’ll notice that it starts up more often. It might also stay on longer in order to reach the desired temperature.

It can be caused by bad coils as well as a failing blower motor. So check these parts before ordering a new installation.

If your coils and blower motor are fine, then these are signs that your HVAC system can no longer produce and circulate the air in your home efficiently. As a result, it requires more time to reach the desired temperature.

If, even after repairs, your system runs for a significantly longer period of time more often than it used to, it’s time to replace the unit.

Loud Noises

It’s normal for older HVAC systems to get louder with age. But when you notice that the following noises, it might be a sign that you need a replacement:

  • the blower is humming louder
  • the outdoor unit is making more noise
  • the furnace is groaning and banging
  • noise before the air conditioner starts up

Some of these noises can be explained by a loose part or a part that needs to be replaced. Others may be related to problems with fans, motors, blowers, and other moving parts. But if the odd noises increase or remain after repair, it’s likely that it’s time to replace your system.

Lots of Repairs

A lot of the individual parts in an HVAC system are repairable and replaceable. But all HVAC systems will eventually wear out and require complete replacement.

And when a compressor, motor, or coil fails, replacement is far more worth it than repairing. The cost of parts, as well as labor for repairing these essential components of your system, are high.

While the upfront cost of an entirely new system seems like a lot, the cost of constant repairs when one of these parts fails isn’t worth it in the long term. That money is better invested in an entirely new system. And when you get that system, be sure to have a professional help you maintain it to extend the life of your investment.

You Don’t Perform Regular Maintenance

Most people don’t realize the importance of performing regular maintenance and checks on their HVAC system. Checking your HVAC system at least once per year ensures they’re working safely and efficiently.

Maintenance helps you catch problems before they lead to bigger issues. It keeps your system in the best working order to increase its lifespan. If you don’t perform regularly scheduled maintenance, it’s more likely that the problem has reached a point of no return.

If you notice a dangerous pilot light situation, frayed or exposed wires and conduits, or other visible damage, your HVAC system may actually be posing a safety risk in your home.

Your HVAC System Is 10+ Years Old

If you maintain your HVAC system properly, it might last you a little longer than a decade. Without maintenance, a 10-year-old HVAC system is considered outdated, inefficient, and a good candidate for replacement.

Beyond the 10 year mark, you can expect an HVAC system to start costing you in repairs. They’ll also cost you more in energy bills as they lose efficiency.

Even the most state-of-the-art technology from 10+ years ago doesn’t come close to matching the energy efficiency of today’s systems. Newer units also have digitized and programmable thermostats that are easy to use and help make your home smarter.

Why You Should Replace Your HVAC

The initial cost of an HVAC system is high, but there are many ways you benefit from a new system. In case you need some convincing on the initial investment, we’ve listed all the reasons you should replace your HVAC when the time comes.
