Frequently Asked Questions (FAQs)

My furnace isn’t working. What caused it?

There can be multiple things, but here are a few quick ideas you can check on your own. First, check your circuit breaker to make sure a switch didn’t trip. What about your air filter? When was the last time you changed it? Is it dirty? Also, you’ll want to double-check that your thermostat is set to the on position. Has the battery within the thermostat been changed recently? Maybe it’s time.

Can you help? My furnace stopped working.

Step 1. Check the thermostat. Is it on? Is it set to the heat setting?

Step 2. Check furnace switch. Did it get turned off? Make sure it’s set to the on position.

Step 3. Check the circuit breaker. Did the circuit trip?

Step 4. Check the furnace filter. Could it be dirty and clogged? Time to replace the filter.

Step 5. Check the furnace front panel. Is it securely closed?

Step 6. Check the gas valve. Be sure it’s positioned to on.

Step 7. Check the air ducts. Could they be blocked?

Step 8. Are you still having issues? It’s time to call a professional.

What’s the lifespan of a furnace?

When you maintain and service your furnace, it extends the life of your unit. On that note, an average lifespan for a gas furnace is 15-20 years, while the average span of an oil furnace is 15-25 years.

Should I fix my furnace or replace it? 

Take the age of your system into account. What will it cost to repair it? How frequently are you doing repairs? Use the $5000 rule of thumb. What you do is multiply the age by the cost of repair per year. If you’ve done that, and find that it’s a number less than $5000, repair it. On the other hand, say your furnace is 12 years old, and the repair will cost $500. Now, multiply 12X500=6000. In this case, it’s greater than 5000. It’s better to replace than repair.

Is there an average cost you can give me to get a furnace fixed?

Average repair costs vary, due to many factors. While we’d say an average is $300, there are things that go into this. It depends on the type of furnace you have, if it’s under warranty, what parts and how much labor is involved. It can vary widely, from $100 to $1200, but most bills we see are in the $170 to $500 range.

How often am I supposed to service my furnace?

Servicing your furnace yearly is a smart idea. We recommend doing it in the fall before the colder weather starts. It prolongs the life of the furnace and makes it more efficient. You’ll also want to know that your manufacturer may want proof that you properly maintained the unit if it comes time to pay for a problem.

What is the cost to replace an air conditioning unit?

Getting central air installed can be stressful when you don’t know what to expect. HomeAdvisor suggest that the average cost of installing central air conditioning runs about $3,700 to $7,000. This should help you get a realistic take on your new investment, but be aware that other things that go into the cost come down to where you live, the type of system you need, along with the condition of your existing air ducts.

How can I figure out if my AC unit is big enough?

You’ll often see 1 ton of AC for 500-600 square feet as an average, but the process is a bit more complicated than that. You need to account for the types and number of windows and doors in your home, along with ceiling height, climate, and even the number of people living in your home. The best thing to do is to have a well-trained HVAC contractor use a Manual J which will help you find the right answer for your needs.

How long will my air conditioning unit last for?

Ready for a new system? If your air conditioning unit is about 12-15 years old, it might be time. The lifespan greatly depends not only on the age, but how you’ve maintained it. Also, how it was installed can play a part on it. As for heat pumps, you’ll get about 14 years out of those. As our systems age, there comes a point where it makes more sense to replace rather than repair a unit. Consider a system that’s over 10 years old right about that point.

Why is it still warm in my house while the AC is running?

Nobody likes when their AC is on the fritz! Did you check your thermostat settings? Are you set to cool, and your is your fan set to auto? Okay, what else could it be? There might be a refrigerant leak, dirty coils, a frozen evaporator coil, or even dirty air filters. There is an entire list of things we can check for to get you back to cool air in no time.

What do I do when I have an air conditioner leak?

Don’t panic! There are a lot of causes, but the most common cause has an easy fix. A lot of the time, you’ll find that you have a clogged drain line. It’s simple enough to fix with a wet/dry vac and the proper attachment. Also, another tip is to use a bit of vinegar. Pour a small amount down the line to help destroy the build-up of bacteria and fungus.

Is there a schedule I should follow for AC maintenance?

We rely on our air conditioners to work well. By servicing your system in the spring before heavier usage, you’ll be helping maintain peak performance. Did you know that an un-serviced system loses 5% of its efficiency? Another way to help your system is by changing out or cleaning your air filters monthly. When it comes to tune-ups, we should mention your heating system should be tuned up in the fall.

About Annapolis, MD 

Annapolis, MD is really a neat place, and offers some great opportunities. Before we get into that, let’s look at the history of this popular Maryland city. Annapolis can be found along the Chesapeake Bay, and is the state capital. While the state was founded in 1634, Annapolis wasn’t the state’s capital until 1694, but at the time was named Anne Arundel Town. They took the Annapolis name the following year.

So, what’s going on in Annapolis, besides government stuff? Well, there’s the Annapolis City dock, Annapolis Art District, Annapolis Boat Shows, and The Maryland State House. We’d be remiss if we didn’t also mention the United States Naval Academy is in Annapolis.

Sailing and boating is great for outdoor summer activities. And, be sure to grab some crab if you’re looking for something delicious afterward. Speaking of summer, the days here get hot and sticky. Make sure you get your air conditioning system serviced or tuned-up before the start of the season. Of course, if you need help or a new installation, we’re just a call away. You’ll want to keep the humidity in check, as it can do damage to walls and untreated wood.

As for winter, the days can be blustery and cold. They don’t get a ton of snow, but, when it does blow through, you’ll want to be ready. January and February are the months Annapolis sees the heaviest snow fall. A quick check of your heating system should be a priority, so you aren’t left in the cold. Have you made an appointment to get a tune-up? Maybe you’re thinking of replacing your system with something more efficient. Either way, give us a shout and we’ll be able to answer your questions and offer a free in-home consultation if needed.
