Spring HVAC Prep

The weather is finally warming up. For the first time in months I left the office and didn’t have to worry about getting frostbite on my spleen. We hit 74 degrees last Friday here in Philly, I took a bike ride and came back looking like a drowned rat, but it was warm. It’s only 36 Fahrenheit today, but Spring is on the way. The coming warmth means we should start talking about your maintenance schedules. Do Your Chores It’s vital to inspect, clean, and maintain your HVAC equipment. It’s going to cost you if you don’t. You should inspect your entire HVAC System at least twice a year: once before spring, and again before fall/winter. These little maintenance checks will keep you, your employees, your customers, and any other guests comfortable year round. As the weather warms up, you will begin to dial back your reliance on your building’s heating system. This is an ideal time to find a warm day, shut it down, and have your contractor do some cleaning and inspections. Most burners will leave some measure of dirt/soot in the combustion chamber for you to clean up. Leaving this there will reduce your system’s efficiency and may eventually clog up the heat exchanger altogether. From a maintenance perspective, this is an ideal time to check that the ignition system is in good shape and doesn’t require any adjustment or replacement. Things like the spark rod in […]

To Do: Preventative Furnace Maintenance

As with all things, an ounce of prevention is worth a couple tons of cure. After a long spring and summer of sitting little or even unused altogether, your furnace needs some attention before the long winter comes. This can vary from model to model, but in general, you can expect your HVAC Professional to do a lot of cleaning and even some replacing.   The Big Cleanout Nearly every fuel-burning heating system is going to produce some sort of soot or ash from running. Modern heating systems are incredibly efficient, but they’ll still produce a bit of waste material. This waste can be combustion byproducts, contaminants left behind in the fuel, or in some cases even microscopic particles of other components of the furnace itself, such as particles from a spark rod. This build up will cause a number of issues over time: Inefficiency, the soot will absorb heat, requiring more fuel than normal to reach the same temperature changes. Dirty emissions, by exhausting the soot out into the open air, a potential health and legal hazard. System failure, by clogging up the burner or otherwise preventing the furnace itself from running. The general process of cleaning up the furnace is straight forward. Your contractor will remove some parts of the case to get into the combustion chamber and use a vacuum to collect the soot. Depending on how much soot there is, it may be necessary to replace […]

Fall AC Maintenance

It’s getting cooler outside. The high today in Philly isn’t even 80 degrees. Just a week or two ago we couldn’t go a day without seeing 90. In another few weeks, we’ll be struggling to see the 70s and we’ll be turning to warmer clothes for the start of fall. As with all things, that means now is about the best time to prepare for winter with some pre-emptive maintenance and cleaning.   We’re Going to Maintain Something… We Won’t Be Using? It’s always best to work on things when you don’t need them and better still to work on them just a little ahead of time. The weather outside is nice and pleasant right now. You can walk outside in a T-shirt and not feel like your arms are going to freeze off. It’s a good time to do any outdoor work before mother nature gives you a nice, awful cold for your troubles. In the case of your air conditioner, there’s a fair bit you can do to get ready ahead of the season. You can clean the area around your condenser, your HVAC contractor can clean out the drainage connections for the drip pan, you can order a protective cover to keep your condenser free of debris throughout the winter, and you can do one last inspection for any worn parts. There is some logic to all of this. Debris is going to trap water from rain […]

Winter is Coming – Prepare Yourself

Today we start to change gears and prepare for the change of seasons. Summer is coming to a close. We’re already seeing temperatures drop around Philly, with our highs falling from the 90s into the 80s. It’ll be a cooler, more comfortable week this week, with temperatures well on their way to the chilly fall norms. Now is about the time to make sure your heating system is ready for a long, busy season.   Why Check the Heater? For most people in the northern most parts of the US and elsewhere in the world, our heating systems have been dormant all summer long. You could have old, gross filters still in the system or discover a mouse has eaten the thermostat wires. There’s also that always looming spectre of hardware failure, when an old part has finally gotten old enough to just give out. It’s warm now and your AC is still running, so you don’t need your heating system yet. Your contractor can have the system apart for a good few weeks, you can use cheaper, slower shipping, and suffer no ill effects for it. This is also a good time for simple, routine maintenance. You can take this opportunity to swap out your air filters, have your chimney cleaned, clean out the furnace, and so on. Different system designs accumulate differenent maintenance needs. Oil burners often need a good cleaning to remove soot, for example.   What […]

When CAN we turn on the AC?

As the weather warms up, we’re caught in a bit of a pickle. Some days it’s 60 or 70 degrees outside, but other nights we can still see lows dipping to 26. Some days we look to our AC systems and desperately want to run them, but is it time? Is it good to run AC for just a few hours a day? Is it good to run them in the bitter colds nights? Are we going to regret running these?   Physics Hate Us We’re going to run into a few issues running our air conditioning in less than roasting weather. We’ve built modern AC, from window units up to multi-ton rooftop monsters, to take a brutal 100 degree summer down to a cool 70 degree oasis. These machines can create temperature drops from twenty to forty or more degrees. This involves creating some intense coolness inside the air conditioner. If the ambient air is 60 degrees and we drop that by 40 degrees inside the air conditioner, we’re going to make it 20 degrees inside. This extreme cold will create ice, the great nemesis of all things mechanical. We don’t start to get to ideal temperatures until it’s about 70 degrees outside. Around that point, we can actually run the AC without having to worry so much about the ice build up. Why is ice a problem? It’s mother nature’s wedge. As water freezes it expands. As water […]
