frequently asked questions

Are There Things I Can Check On My Own If My Furnace Isn’t Working?

Step 1. Something that’s overlooked can be as simple as the setting. Did it get knocked off from the “on” position? Double-check.

Step 2. Did you think about the furnace switch? Be sure to double-check that it’s on.

Step 3. Sometimes your circuit breaker gets tripped and needs a quick flip of the switch.

Step 4. Could your air furnace filter be clogged? When was the last time you changed it?

Step 5. It’s easy to overlook the front panel of the furnace. Make sure it’s securely closed.

Step 6. What about the gas valve? Could that have been turned off? Check to make sure it’s on.

Step 7. Have you checked the air ducts? Make sure there’s nothing blocking them, so you get the best air flow.

Step 8. It may be time to give us a call if you’ve gone through the steps and nothing has helped.

How Long Will My Furnace Last Before It Needs To Be Replaced?

The answer depends on if you have an oil furnace or a natural gas furnace. An oil furnace with proper maintenance will see about 15-25 years of life, whereas a gas furnace will get about 15-20 years out of it

When Should I Service My Furnace? How Many Times Should I Do It?

We recommend that you service your furnace at the start of colder weather. There are a couple of reasons to keep in mind. First, it helps your unit run more efficiently, which also helps extend the life of your furnace. Second, your manufacturer’s warranty can become ineffective if you haven’t kept up with yearly maintenance and inspections, and they’ll want proof! So, be sure to save yourself a hassle, and help extend the life of your unit with a yearly appointment to be serviced and maintained properly.

The AC Is On, But The Temperature Isn’t Changing. Why?

Unfortunately, it’s not always one simple answer. There are different things that can cause this to happen. Consider that it could be a frozen evaporator coil or refrigerant leak. It might also be a dirty air filter or a dirty condenser coil causing you issue. Are your vents blocks? Is there faulty wiring? And don’t forget to check your settings. Is your unit set to cool, and the fan set to auto?

My Air Conditioner Is Leaking Water. What Can I Do To Stop It?

It’s frustrating to see water, because we often imagine it’s a big problem. The good news is that while it can be something else, most of the time it’s an easy fix. You may have a clogged condensate drain line. If you do, simply take a wet/dry vac and use an attachment to clean the line. While you’re at it, another tip is to use vinegar. Vinegar? Yes! Pour a small bit of vinegar down the line to help destroy bacteria and fungus, which can help prevent future problems.

How Often Should I Get My AC Serviced?

AC systems keep us cool when we need it most, but if you don’t take maintenance seriously, you could be losing 5% efficiency each year. That goes for your heating system, too! When you want your system to work at its peak, it’s important to add a tune-up to your list of things to do. One more thing to help your unit run smoothly is to change out the air filters regularly or clean them. We suggest doing this monthly.

About Catonsville, MD

Catonsville, Maryland is a town just outside of Maryland’s capital seat of Baltimore. Sitting west of the city, Catonsville is an easy commute if you work in Baltimore. It’s known for being home to the University of Maryland, Baltimore County, which is a research university.

It was established in 1831 by European settlers, but was first home to two Native American tribes—the Susquehannocks and Piscataway tribe. The town’s first name didn’t contain the “s” making it Catonville, but it was later added. To commute to the city of Baltimore, horsecar service was provided starting in 1862, but by 1884 railroad service had come to the area. The town is just over 14 square miles.

What else is going on in Catonsville? Well, you’d be surprised at the nice variety of choices. Stop by the Lurman Woodland Theatre or enjoy some quality time at the Benjamin Banneker Historical Park & Museum or enjoy a good meal at Catonsville Gourmet. If you’re interested in learning more about the area, be sure to visit the Greater Catonsville Chamber of Commerce for more ideas.

Like most Maryland winters, the days can be cold and windy. There’s always a chance of snow, so make sure your heat pump and furnace are in good working order. The cold temperatures range from 27 to 50 degrees during the winter, with January generally being the peak of the cold season.

As for summers, they are hot and humid, with a nice mix of sunshine and plenty of time to enjoy outdoor activities. During the summer months, you’re looking at average highs just about 80 degrees and higher. That’s enough have you reaching for the central air conditioning.

Another thing to keep in mind is that with humid, muggy summers there’s a lot of excess moisture in the air. That means you’ll want to make sure to keep your air conditioning running so you don’t deal with excess dampness, mold, or mildew.

With a dependable HVAC company, you won’t have to think about muggy details. Simply dial us up and we’ll make sure everything is in good working order. Whether you need air conditioning & heating service or a new unit, we’re here for you in Catonsville.
