The Furnace Filter: The Forgotten Hero of Your Heating and Cooling System.

It's a bright, sunny morning, and you don't have a care in the world. The birds are chirping, the coffee is hot, and the forecast calls for blue skies all day. Then, in a fit of panic, you suddenly remember that it's been a while since you changed your furnace filter. How many times has this happened to you? Probably never. Most people don't give their furnace filters a second thought. But maintaining your furnace or air handler's air filter is crucial to your indoor air quality. Improve every breath with these helpful tips. Why filter at all? Today's homes are built better than ever. And while tighter tolerances and better seals are great for insulation, they also trap contaminants inside the home so they circulate over and over. That is, until they're drawn into somebody's lungs where they can trigger disease, allergies and other respiratory difficulties. Basic isn't always best The type of filter you install will have a huge impact on indoor air quality. The least expensive air filters are usually made of a loose fiberglass mesh, are about an inch thick and cost about a dollar each. While they'll protect your furnace from larger particles, they don't do a lot towards protecting your lungs from tiny particles. High efficiency can be highly effective Inexpensive, one-inch fiberglass filters may not provide enough filtration to affect the quality of your air. Instead, consider a pleated, high-efficiency filter like the Carbon Clean 16 filter which has a MERV 16 rating to achieve the highest possible filtration efficiency. While a more expensive option, it will do a better job of capturing the contaminants that would otherwise circulate in your home. Don't forget to check The frequency with which you change your air filter can depend on many factors, including the type of filter you're using and the amount of contaminants (dust, dirt, cooking fumes, smoke) your home generates. Checking your filter at least once a month is always a safe bet. If it's visibly dirty or dark, it's time for a change. If you have a professionally installed air filtration system, have it maintained according to the manufacturer's specifications. Size your filter correctly A filter that's too small will let dirty air pass around it. A filter that's too big will not fit properly in your system. Make sure you're using the correct size for your furnace. You can verify size either by checking the size of the old filter you're replacing, or by checking the owner's manual of your furnace. The cleaning power of a powered air cleaner For the most effective whole-house air cleaning, consider investing in an electrostatic air cleaner or other powered solution. Many of them use an electrical charge to gather smaller particles that filtration cannot catch. You might want to consider an Air Purification System, use multiple technologies in unison to clean, deodorize and purify the air for a truly healthier, cleaner environment. Blackall Mechanical will be glad to advise. Fill out a request for service form Air Purification Info and we'll contact you as soon as you submit your information. We are happy to help you and your family!

Building Your Complete System: the Smarter Way to Better Comfort.

If you're in the market for a new heating and air-conditioning system, there are a few things to consider when making your purchase. Because when you have all the facts, you'll enjoy greater comfort, better energy savings and an overall more enjoyable indoor environment. When replacing a piece of air-conditioning equipment, it's always good to consider the advantages of installing a complete new system instead of just swapping out one component. There are several important reasons for this. When you replace an entire system at once, it will be comprised of components that have been designed to deliver the same level of efficiency. So all parts of the system can work together to save you energy, and deliver the savings you're expecting. Pairing compatible equipment also means longer system life as well. When one part of the system is older, it creates a bottleneck that can make every other component work harder to compensate.* Communicating about comfort and efficiency Another reason to consider equipment from the same manufacturer has to do with the “communicating” capabilities built in to a lot of modern equipment. Communicating systems connect furnaces, heat pumps, air conditioners and air handlers in the same system together via special electronics. This allows each piece of equipment to optimize its performance based on what the other parts of the system are doing. As an example, the iComfort Wi-Fi® communicating capabilities found in premium Lennox® equipment lets multi-stage and variable capacity furnaces and air conditioners fine-tune their output and energy use to deliver consistent savings, and even monitor themselves to ensure proper operation. Unfortunately, there is no universal communicating standard shared among manufacturers. So mixing and matching your equipment may provide you with heating and cooling, but without the communicating ability, your system won't operate at its most effective or efficient level. Building the right system for your climate. When it comes time to create your new system, the equipment you select will be determined largely by the climate where you live. Because while you can technically build a system any way you want it, you may end up spending more on things you don't need. Warmer climates: Consider a heat pump and air handler. Heat Pump A heat pump functions as both a heating and cooling unit. While a furnace would work just fine in this part of the country, a heat pump that uses electricity will most likely be the most energy-efficient solution even during cold snaps. Air Handler To circulate the air throughout your home every day of the year, an air handler makes a smart choice. Essentially a blower motor in a cabinet, an air handler can circulate warm air in the winter and cold air in the summer. While a furnace can do the same thing, the burners aren't needed in warmer climates. Moderate climates: Consider a dual-fuel system. In moderate climates, temperatures can be warm in the summer, cool in the fall and cold in the winter. And while the temperatures may not drop quite as low as they do in cold climates, they can still get low enough to make a heat pump ineffective. For these climates that can experience everything from moderate to severe temperatures, a dual-fuel system is the most energy-efficient solution to choose. In a dual-fuel system, a heat pump and a furnace are paired together to work for maximum efficiency. Different temperatures, different functions During summer, the heat pump functions as an air conditioner to keep your home cool. When weather starts to get cold, the heat pump will switch to heating mode to provide warmth. But if the temperature drops so low that the heat pump cannot get enough heat to keep your home comfortable, the system will automatically turn the heat pump off and switch to the gas furnace for heat. When we install your dual-fuel system, they will set the point at which the heat pump hands off to the furnace based on how much electricity and gas are in your area. So regardless of what the temperature does, you'll always stay comfortable in the most energy-efficient way possible. To get the system that's right for your home and your climate, have a conversation with your Blackall Mechanical Heating and AC Specialist.

Regulating Humidity Levels Can Help Protect Your Health, Home and Comfort

What's the first thing you think of when you hear the word “humidity?" Hot, heavy, sticky air probably springs to mind. But moisture levels in the air can do a lot more than ruin your comfort. And they aren't just a problem in hot weather, either. Normal humidity levels Humidity is technically the measure of the level of moisture vapor suspended in the air around you. Although you can't see it, it's still there. Normal humidity levels for ideal comfort are somewhere between 30% and 50%. That doesn't mean that the air around you is comprised of 30-50% water. Instead, it means that the air is holding between 30-50% of the maximum amount of moisture that it can contain.

Too much humidity When the air has too much humidity, it can harm your comfort, your home, your possessions and your health. Your comfort When there's too much humidity, your body can't regulate its internal temperature through the process of evaporation. In fact, if you're in a humid room that's the same temperature as a room with less humidity, the humid room will feel warmer to you. Overly humid air can create a breeding ground for mold and mildew, which can cause staining and damage to your home. High humidity can also cause wood to rot over time. Moreover, moist wood in your basement and attic can attract insects. Your possessions If you have too much humidity in your home, it can cause swelling in furniture and other items, which can cause them to warp. Your health Too much humidity won't just make you uncomfortable, it can also make you sick. High moisture levels encourage the growth of fungus, mold and dust mites, both of which can create breathing difficulties for people with asthma and allergies.

The Epic Battle for Temperature Control.

Thermostat wars are being waged in households across the country. It's an epic struggle of stealth, shouting matches and utility bill waving. The combatants come in all ages, sizes and genders, and the fight can rage for months—even years. But fear not, solutions are available that can help bring this fight of the Fahrenheit to an end, and zoning is one of them. ____________________ How zoning can turn a combat zone into a comfort zone A zoning system divides your home into separate areas, known as a “zones,” and allows you to customize the air temperature in each zone. The system involves multiple thermostats which operate dampers within the ductwork of your forced-air system. The thermostats constantly read the temperature of their specific zone, then open or close the dampers according to the thermostat's settings. Perfect for every room and everybody Zoning is helpful for houses with inconsistent room temperatures and is also great for heating or cooling individual rooms based on their occupant's specific temperature preferences. So everyone gets the comfort and room temperature control they want, and you get the conflict resolution you need. A good idea for your home and your family A zoning system not only helps to keep your family members happy and comfortable, but it can also be an ideal heating and cooling solution if you have: Large windows in your home A top floor that's always warmer than the lowers floors Uneven home temperatures A house level that's partially or completely underground Rooms you seldom use Rooms that constantly feel stuffy A room that was added after your heating and cooling system was installed A home office containing heat-producing electronic equipment High heating and cooling bills Noticeable hot or cold spots in your home Extra comfort and additional benefits Energy efficient and effective, a zoning system offers comprehensive benefits that go well beyond simply heating and cooling your home. These benefits include: Extra Comfort Zoning meets the specific temperature and airflow requirements of one area, without affecting other areas. Enhanced Efficiency A properly designed energy efficient zoning system can save you hundreds of dollars in energy costs each year and can pay for itself in as few as two to five years. And, when used with a programmable thermostat, zoning can mean home energy savings of up to 35 percent.* Precise Control Zoning divides the home into different areas, and divides comfort into different levels, giving you more choices and control than ever before. Quiet Performance When integrated with variable-speed and/or two-stage HVAC systems, zoning allows your heating and cooling equipment to run at peak performance and efficiency. And lower speeds mean lower sound levels. The right zoning system for you If you're looking for a permanent resolution to your thermostat wars,then an advanced Lennox® zoning system, could be exactly right for you. We are a Lennox Authorized Dealer! Remote zone control When you combine an iHarmony zoning system with an Wi-Fi thermostat, you can adjust the temperature in any zone remotely and conveniently from your smartphone, tablet or other web-enabled device. *Source: U.S. Department of Energy statistics
