Frequently asked questions

Why Isn’t My Furnace Working Right?

Have you checked the thermostat? Sometimes it’s as simple as an improper setting. If that’s not your issue, check the battery on your thermostat. Dirty filters sometimes cause a problem as well, so be sure to change yours regularly. Did your circuit breaker trip? Have you checked? If your power switch goes, it might be as simple as flicking it back on.

What Should I Do? My Furnace Isn’t Working Right.

Step 1. Did you check to make sure your thermoset is set to the heat position? It’s a basic and quick thing you may have overlooked!

Step 2. Another thing to check is if the furnace switch is set to the on position. You’d be surprised how often this little thing is the culprit.

Step 3. Whoops! Did the circuit breaker trip? Give it a quick check.

Step 4. Is the filter clogged? Dirty filters can cause big issues! Get a new filter and replace it.

Step 5. Is the front panel of the furnace securely closed?

Step 6. Have you checked the gas valve? You want to be certain it’s in “on” position.

Step 7. What about the air ducts? Did you make sure nothing is blocking them?

Step 8. If you went through each step and you’re still stuck, it looks like it’s time to give us a call.

Is There An Average Time span That A Furnace Should Last?

The lifespan of a furnace often depends on how well it’s been maintained. When serviced regularly, you’ll see about 15-20 years from a gas furnace, and about 15-25 years from an oil furnace.

How Big Of A Unit Do I Need To Cool My House?

There’s no one right answer, but a general rule of thumb is about 1 ton of AC for every 500 to 600 square feet. But, what’s important to know is that there are varying factors that go into the equation and that might not be enough in your circumstance. A qualified contractor will look at the types of windows and doors you have, how many of them, what your insulation is like, the height of your ceilings, and even how many people live in your home and the climate you live in. They’ll use a Manual J to get you an estimate, so you’ll know what will work best in your situation.

What’s The Life Span Of An AC Unit?

When an air conditioner unit is well maintained, you should see about 12-15 years out of it. A heat pump, about 14 years. It comes down to how it was installed, how well you’ve cared for it, among a few other small details. One thing we’re often asked is about an aging unit. Once it’s past 10 years old, you may want to replace it, rather than repair it.

How Do I Stop My AC From Leaking Water?

Did you know that while there are multiple possible answers, most the time it’s a pretty common solution? Check the drain line and make sure it’s not clogged. If it is, simply take a wet/dry vac with the help of an attachment and clean it. That should help. Also, another neat tip is to use a little bit of vinegar and pour it down the line. What this does is help destroy bacteria and fungus. You can use this tip 2-3 times a year for best results.

About Randallstown, MD

Randallstown, Maryland sits in Baltimore County. The town got its name based on two brothers who ran a tavern in the area. The Baltimore suburb has a population of just over 30,000 people. The area itself sits on just over 10 square miles and features the historic Choate House which was built all the way back in 1810!

Randallstown sits on the southwestern side of the state and offers opportunities like the Randallstown Community Center and the Baltimore County Public Library Randallstown Branch. If you’re looking for a bite to eat, you’ll want to stop by Akbar Palace, Colin’s Seafood & Grill, or be sure to visit the Identity Ultra Lounge.

If you’re heading to Randallstown or have just moved to the area, there are a few things to keep in mind. First, the summers get sticky and hot, so make sure your central air conditioning system is running at its peak. You’ll appreciate climate control on those muggy nights, and so will your walls. A good system will help keep excess moisture out of the home. With our HVAC services we can help give your unit a tune-up before the hot weather hits.

As for winter, you’ll want to prepare for windy, cold days, and a mix of snow. If your furnace and heat pump are in good repair, you shouldn’t have any issues handling the colder weather that sits over us in January and February. Of course, if you find you’re having a problem or need a new system, we’re always here to help. Simply give us a call and we’ll not only answer all your questions but get you up and working in no time.

While the summers are hot, there are some nice days mixed in there, and with four solid seasons, we don’t see extreme temperatures like some states do.
