Fall furnace maintenance tips


Well, tomorrow is officially the first day of fall, and that means the day when we turn our furnace on is drawing near. Since you’ve been relying on your air conditioner for the past few months rather than your heater, it’s important to pay attention to your furnace well before you really need it to double check that it is still in good working order. Here are a few fall furnace maintenance tips we encourage you to use when you get started:

Turn it off: Most importantly, don’t begin any work until you turn off your furnace completely. If you aren’t sure where the switch to do so is located, check by the top of your basement stairs; if it isn’t there, start looking on the walls near the system. Then, head on over to your oil tank or gas pipe and turn off the fuel shutoff as well to ensure that your furnace isn’t being supplied with either of these products as you work.

Clean out the combustion chamber: Once you’re sure that your system is turned off, remove the door leading to your combustion chamber so that you have full access to it. Then, using a vacuum, suck up any dirt that has built up over time. As soon as you’re done, make sure to check for any holes that may have formed due to corrosion and seal if needed.

Change the air filter: We simply can’t say it enough – one of the most important parts of furnace maintenance is changing the air filter. Even though your furnace has been dormant for the past few months, it’s still a good idea to put in a fresh filter at the start of fall – you want your system to work as efficiently as it should, right?

Wipe down the pilot: Since the pilot is the part of your system that encourages heat to start flowing, you’ll want to make sure it isn’t covered with any dirt that could get in the way. Cleaning it is simple – just wipe off the dust until it is as good as new! If you need to get into tight spaces, the Family Handyman suggests using a straw to help.

Contact a professional: After you’ve completed the easier tasks, contact your local HVAC specialist to have professional maintenance performed. Though you may feel confident that you’ve done it all, only an expert can guarantee that your system is ready to go.

Tips For Taking Out Your Window Air Conditioner

With Labor Day having passed, many of you may be getting into the mindset that summer is officially over. And even though we are still battling some high temperatures, soon enough it will be time to prep our homes for the fall.

That being said, if you have a window air conditioner at home, you may be starting to think about taking it out. Here are step-by-step instructions you can use when doing so:

How to take out a window air conditioner
  1. Power down your unit and unplug it. If your wiring is quite lengthy, you may want to find a way to tighten things up so that it doesn’t get caught during the rest of the process.
  2. Place a towel or other protective covering on the floor under the unit to catch any water that drips out.
  3. Assuming you have secured the air conditioner to the window with screws, take them out and slide in your unit’s accordian side panel/side curtain and frame.
  4. Grab the air conditioner firmly from behind, then have a buddy lift the window. As the air conditioner is no longer held in by the window, be prepared for it to tilt or move a little.
  5. Remove the unit from the window and place it on the towel below to allow any extra water to leave the system.
Although taking your air conditioner out of the window seems pretty simple, always have a friend near by. Not only can they help when it comes time to physically remove the unit, but it’s always a good idea to have a second set of eyes and hands available in case the situation should get a little hairy.

Ways To Save Energy Even When The A/C Is On

When it comes to conserving energy, it’s only natural to think that you must turn off major appliances such as your air conditioner. However, did you know that you can save this important resource even when your cooling unit is on? With help from Apartment Therapy, we’ve put together the following list of tips to help you reduce your energy use despite your system being put to work:


Raise the thermostat: When the sun goes down and the temperatures drop, try raising your thermostat’s setting. Although your unit will still be running, you can give it a bit of a break by not requiring it to work so hard to keep you cool since the temperatures outdoors are probably not as high.

Ways to save energy when your air conditioner is onTurn off the lights: Since your lights naturally radiate heat, having them on for a long period of time can make your home hotter. As a result, your air conditioner will have to work harder to keep things cool! To prevent such from happening, be sure to keep the lights off for as long as possible to naturally reduce the temperature inside your home.

Re-position your furniture: Do you have couches, chairs or other pieces of furniture positioned closely to your cooling unit? If these are too close to your A/C and covering its vents, it could take quite a while for you to finally feel cool – meaning, your A/C will be probably be working harder than it has to. To avoid this, simply re-arrange your furniture so that there is nothing in the way.

Last but certainly not least, it’s essential that you perform maintenance on your unit regularly. All too often air conditioners use more energy simply because they haven’t been serviced. To learn more about how our team can help you with this important task, click here.

How To Keep The Air From Your A/C Inside This Summer

Have you ever had your A/C running for hours on end only to realize that the air wasn’t keeping your room cool? If so, we know just how frustrating and even alarming this can be. However, just because your home hasn’t reached desired temps doesn’t mean that your system is on the fritz – it could simply just be a sign that there are cracks that need to be sealed.


To ensure that the air coming out of your air conditioner doesn’t escape before it has the chance to cool you down this summer, be sure to do the following:
  1. Inspect all windows and doors for signs of cracks where air may be leaking from. If any are present, add caulk or weatherstripping where necessary.
  2. Check any visible insulation for dirty spots – this could be a sign of air leaks and mold. Should leaks have formed, seal them by using a low-expansion spray or install house flashing if needed.
  3. Similar to the way you looked for dirty spots in your insulation, check for dirty spots on your ceiling paint and carpet too. When this is evident, there may be air leaks where your walls meet your ceilings and floors. Once again, this requires caulking!
  4. If your kitchen has an exhaust fan, cover it when it isn’t needed to prevent cool air from slipping through the cracks.
  5. Install foam gaskets behind your home’s outlets and switch plates. Though these are a small feature of the home, they can cause leaks in a big way!

Since your air conditioner works hard to produce cool air, it’s important to make sure that all of its efforts don’t go to waste! If after sealing off all possible leaks you are still concerned about your air conditioner’s performance, give the expert technicians here at Airtech of Stamford a call!

Tips For Cleaning Your Condenser Coils

Just like your air filters need changing, your air conditioner’s condenser coils need cleaning. As part of an intricate system that works to maintain the temperature of your home, it’s important to pay just as much attention to this component in order to keep everything running smoothly.


Today, we’re taking the time to outline the steps it takes to clean condenser coils so that you can be prepared for the start of the summer season:

How to clean your condenser coils
Step 1: Before you do anything, turn off the A/C. And we don’t just mean the power button, we mean disconnect it completely so that power is no longer running to it.

Step 2: If plant life has gotten in the way of your system, you’ll need to trim it back so that it doesn’t wind up inside of the unit during the cleaning process. Not to mention, it will make getting close to the unit easier for you!

Step 3: Using a screwdriver or a nut driver (depending on the type of system you have and how it is put together), remove the outer case so that you can begin to access the interior.

Step 4: Take off the top of the air conditioner. If your air conditioner is set up in a way that the fan assembly is located on the top, be cautious of how you are handling it so that you don’t wind up damaging it.

Step 5: Begin to clean off the fan blades, the fan motor and the shaft. Then, move onto the condenser coils and remove any dirt that you see – a whisk broom can aid with this process.

Step 6: Using a coil cleaner, remove the additional dirt that has been trapped between the coils and then rinse. But be careful about how you do so – not only should you be gentle, but you should also definitely cover anything related to the system’s wiring.

Step 7: Last but not least, check the coils for any damage and make sure that none have been bent. If they have, you can straighten them out using a “fin comb.” Once you’re sure everything is in the right place, you can reassemble the unit back to its original state.
