Extreme Cold and Your Home Appliances

Snow and HVAC Hagerstown MD

For the most part, your home’s appliances are designed to withstand both hot and cold temperatures. However, extreme cold can still damage your home, especially when you have appliances up against outside walls or in your garage or basement. Here’s what you need to know to keep everything running this winter.


Your outdoor unit is designed to handle even extreme cold, but it can get covered in ice, which will cause an emergency shut-off. If that happens, you will need to remove the ice in order to get your heater running again. Avoid this by keeping that area clear or even building a fence around the outdoor unit if snow tends to accumulate there.

Washing Machine

Your washing machine should be fine but your water lines can freeze if they are connected to an outside wall. Disconnect them when you’re not using them or wrap them in pipe insulation for the duration of the winter. If you choose to insulate them, make sure you check it each winter before extreme cold temperatures arrie.


Your fridge in your house should be fine, but any refrigerators or freezers in your basement or garage may need some extra care. You can use a space heater to keep things warmer on the coldest days or disconnect any water hoses that you don’t need. If you do need to use them regularly, insulate them when you insulate your pipes.

If you have questions about getting any of your appliances through the winter or you need help getting them prepped, contact us at Larry & Sons today!

UPDATE: Our Fall Focus: Donate 2020 Meals to Feed Hungry Kids!


With your generous support, Larry & Sons was able to not only meet our goal of 2020 donated meals in 2020, but we exceeded it! As a result, we are keeping this open so that Maryland children can continue getting the meals they deserve this holiday season.

Larry & Sons wants to thank YOU for your incredible generosity during this time. We couldn’t have done it without you!

Right here in Maryland, 1 out of every 4 people is facing food insecurity. The hunger problem has only gotten worse as COVID-19 has ravaged our nation and forced so many people out of work. 

At Larry & Sons, our commitment to the local community goes back 60 years, from our humble beginnings as a local plumbing company. We are not a franchise nor a chain…this is our home, and these are the only markets we serve. As such, we stand steadfast committed to helping in any way we can during particularly challenging times.

We are partnering with the Maryland Food Bank, whose mission is to help free people from the grip of hunger. They aim to give hungry Marylanders access to healthy, nutritious food for their families so they don’t ever have to choose between food and anything else.

Our goal is to donate 2020 meals by the end of the year. So how can you help your local community by partnering with Larry & Sons this fall?

Every New USA Membership Feeds A Local Child For 1 Week!

For every new “USA Membership” (Ultimate Service Agreement) sign up through the end of 2020, Larry & Sons will feed 1 hungry local child (3 meals a day) for 1 week.

You get the benefit of excellent service, we get the benefit of serving you, and a local child gets to eat well for 1 week straight. We see this campaign as a total win-win win!

Ask your technician on your service call about this program, or just call our offices to learn more.

At Larry & Sons, we don’t believe that anyone deserves to go hungry and we want to work to solve the food insecurity issues that so many of our friends and neighbors face.

Let’s see how many people we can feed in 2020!

Changing Your Furnace Filter FAQ

Here at Larry & Sons, we get a lot of calls with questions about furnace filters. Here’s what you need to know to keep your furnace in Hagerstown running well so you can stay warm this winter.

How Often Should I Change My Filter?

We recommend changing your filter once a month when you’re running your furnace every day. If you’re not running yours that often or you want to be sure it needs changing each month, ask one of our professionals. We’ll evaluate your particular furnace and tell you how often we think you should change your filter.

What Type of Filter Should I Use?

Most people find that normal furnace filters work perfectly fine for their needs. If you struggle with allergies at home or you worry about indoor air quality, talk to one of our HVAC professionals about using a furnace filter with a higher MERV rating. These filters trap more particles but they can also cause your furnace to experience more wear and tear. We’ll help you decide if they are right for you.

How Do I Change My Furnace Filter?

Find the access panel in your furnace. Remove any screws holding it in place and flip it up or remove it. Take out the older filter and put the new one back in its place. Make sure you install it with the proper side up so it filters effectively. Replace the access panel and note the date so you know when to change the filter next time. Dispose of the older filter.

Call Larry & Sons for Furnace Services!

If you aren’t comfortable changing your filter yourself or you’re not sure how to access it, contact one of our professionals. We’ll help you find the solutions you need so you can change your filter regularly. Contact us today, or schedule a service online!

Should I Keep My Heater at One Temperature All the Time?

We talk to our customers about energy efficiency all the time. One of the questions we get asked the most is “is it better to keep my house at a constant temperature?”

The short answer is that yes, you should, in many situations. However, there are few times when you don’t need to do that.

Thermostat Options for You

Most of the time, the best solution for energy efficiency is to set your thermostat at one temperature and leave it there. The lower you set it, the less your heater will have to work. Even if you set it higher, though, it’s better to set it and leave it.

However, a programmable thermostat allows you turn your heat up when you’re home and down when you’re gone, without ever experiencing discomfort. Just tell the thermostat when you’re coming home and it will get your house toasty warm before you get there, while still allowing you to keep your home cooler while you’re gone.

Smart Thermostats

You can take the level of control one step farther by choosing a smart thermostat. In addition to allowing you to program different temperatures for different times of day, this will allow you to control your home’s temperature via smartphone. If you come home unexpectedly, you can make sure your house is already warm when you get there.
