Window Units Vs. Central Air: Which is Best?

Thursday, May 25th, 2017

Where would we be without air conditioning? (Other than the pool!) Air conditioners have the power to make even the hottest and most humid days enjoyable. But nowadays, there are so many air conditioning options available, it can be hard to know which is best for your family’s needs. That’s why we’re breaking down the two most popular options, central air and window units, and telling you which is best.

Leslie Heating and Cooling Window Units Vs. Central Air Which is Best

Energy use. The average window unit uses between 500 and 1500 watts. While a central unit (installed in a typical 4 bedroom house) uses about 3,500 watts. So if you’re concerned about energy use, you may want to choose a window unit.

Installation cost. Nearly any homeowner can install a window unit on their own, making it an incredibly inexpensive (if not free) installation. Central air on the other hand is more expensive. Most homeowners will have to call a professional to install the ducts needed for central air throughout their house.

Room size. If you’re trying to cool a large family room, a window unit may not have the power to cool the far side of the room.

Aesthetic. Some homeowners opt for central air simply because they don’t like having a large appliance sitting in their window. On this one — to each his own.

Time left in your home. Central air is usually a better investment for new homeowners who plan on staying in their house for the next 10 – 20 years. If you plan on selling your house within the next 5 or so years, you probably won’t see a return on central air.

Programmable thermostats. One of the biggest benefits of central air is that you can program your unit to automatically adjust the temperature of your house throughout the day. This means you can program your house to be nice and cool the minute you return home.

If you’re tired of coming home to a hot house and want to purchase a programmable thermostat, Leslie Heating & Cooling can set you up in no time! We’re a family-owned and operated business based in Woodridge, Illinois and are here for all of your pre-summer cooling needs.

5 Easy Ways to Go Green in Your Office

Wednesday, May 17th, 2017

We all grew up learning the “Three Rs” of environmentalism — reduce, reuse, and recycle. But recently, that three has been upgraded to a five, with “repair” and “rethink” being added to the former “green trio.” While homes and schools were some of the first to jump on board the green bandwagon, businesses are still struggling to find ways they can save on energy, supplies, and so much more. If your business is looking to go green this summer (or if you simply want to suggest a few of these ideas to your boss) here are a few ways to do so.

Leslie Heating and Cooling 5 Easy Ways to Go Green in Your Office

Shutdown your computer. Believe it or not, computers draw more power during the 16 hours a day they are left idle, than the 8 hours a day they are actually being used. At the end of the day, turn off your computer instead of just putting it on sleep mode. On long weekends or holiday breaks, you should unplug your computer completely to prevent wasting phantom power (power that’s consumed when something is turned off but still plugged into a live outlet).

Switch to reusable pens. Each year, Americans throw out 1.6 billion pens because they’ve run out of ink. Cut down on waste by switching to reusable pens. In the long run, the refills are actually less expensive and take up less storage space than traditional pens.

Put a pause on printing. Though most of us feel like everything has moved from paper to digital, companies are still using plenty of paper. Instead of printing out an agenda for everyone in the room, try incorporating it into the beginning of a PowerPoint presentation. When you do have to print, set your printer to the double sided setting.

Use compact fluorescent bulbs. Fluorescent bulbs use three times less energy than incandescent bulbs, and last 10 times longer. That means you’ll save on energy costs and bulb replacements.

Install a programmable thermostat. Even in the middle of summer, most employees report being cold in their office. Send out a questionnaire and ask your employees if they’re too cold during the day. Depending on the results, you could likely bump the temperature up a few degrees! A programmable thermostat will give you the ability to regulate temperatures throughout the day. When employees are busiest, you can set the air conditioner a little lower, then have it automatically raised a few degrees while people are out to lunch or getting ready to leave for the day.

Understanding the Different Types of Insulation

Thursday, May 11th, 2017

We know — insulation isn’t the most glamorous home renovation. Picking out tile for your bathroom or redecorating your basement is certainly more exciting. But when it comes down to it, insulation is incredibly important and doesn’t quite get the attention that it deserves (since most homeowners don’t even know what kind they have). If you’re thinking about renovating your home or want to add more insulation before the summer heat strikes, make sure you know which type is best for you.

When installed correctly, insulation is your best ally in energy efficiency. If the insulation in your home has been installed improperly, you could be wasting a lot of energy — and money — on heating and cooling your home inefficiently.

HVAC Terms Every Homeowner Should Know

Monday, May 8th, 2017

Your technician just told you that your evaporator coil is broken, your refrigerant lines are cracked, and your EER and MERV ratings are low…now what? When it comes to talking with your HVAC technician, industry jargon can quickly confuse even the most tech savvy homeowners. Whether you’re looking to purchase a new HVAC system or just want to make sure that you’re getting the best out of the one you have, here are a few HVAC terms you should know.

Leslie Heating and Cooling HVAC Terms Every Homeowner Should Know

Condenser: This is the part of an outdoor air conditioner or heat pump that compresses and pumps the right amount of refrigerant needed to keep your house cool.

EER rating: The ratio of a unit’s cooling capacity to power input. The higher your EER (Energy Efficiency Ratio) rating is, the more efficient your AC unit is.

Evaporator coil: The part of an HVAC unit that absorbs heat from your house. It’s usually found inside the air handler or attached to the side of your furnace.

MERV rating: Just like how an EER rating is used to rank the efficiency of your entire unit, a MERV (Minimum Efficiency Reporting Value) rating is used to determine the efficiency of your filters. Every unit has filters with small holes that allow air (but not harmful particles) through. The higher your MERV rating, the smaller (and therefore more efficient) the holes are in your filters.

Programmable thermostat: A programmable thermostat is able to adjust the temperature of your house throughout the day, based on a schedule you set. In the summer, many homeowners will set the temperature higher during the day (when they’re at work) and lower around the time they get home.

Refrigerant lines: The two copper lines that connect your outdoor AC or heat pump to the indoor evaporator coil.

Thermidistat: We know what you’re thinking, but no, we didn’t spell thermostat wrong! Like a thermostat, a thermidistat monitors the temperature of a room, but it also tracks humidity levels and can adjust your HVAC accordingly.
