Get Help Going Green! EWEB Offers Eugene Homeowners New Incentives

On October 17th, the Eugene Water and Electric Board (EWEB) had an exciting announcement for homeowners: for the rest of the 2013 heating season, they are offering rebate and loan programs for a variety of energy conservation projects! Among the programs that they offer, Home Comfort is particularly excited about the following programs that are available to Eugene homeowners once again:

Ducted Heat Pumps: If you’ve been looking to install a new ducted heat pump, EWEB can offer homeowners the choice of receiving a $500 rebate off the price of your new system, or the flexibility of a zero interest loan.  Manufactured homes can qualify for loans up to $7,000, while site-built homes may receive a loan up to $9,000!

Ductless Heat Pumps: The savings are just as good for ductless heat pump installations! The available rebate for a new ductless system is now $750.00; some homeowners may also qualify for the option of a zero-interest loan up to $4,000, with the possibility of additional funding (depending on how many indoor units your new ductless system requires).

Insulation: Along with heat pumps, EWEB’s Weatherization program has also returned! By upgrading your insulation, you can cut down on energy bills and take advantage of the option of a rebate or a loan. EWEB offers a rebate of $0.40 per square foot of upgraded insulation, which may cover up to 50% of the price of your project. And of course, they also offer generous zero-interest loans of up to $4,000 for single-family residences.

With the rollout of these new energy conservation programs, there are many opportunities for savings. Besides the financial assistance offered by these programs, many of these heating and cooling systems qualify for state and federal tax credits. And in addition to saving money on your energy bills, upgrading to a more efficient heating and cooling system and updating your insulation can add to the value of your home!

Remember, the project must be performed by a qualified participating contractor like Home Comfort to be eligible for funding from the program. For complete information on EWEB’s current energy conservation programs, please visit www.eweb.org/saveenergy/home.

Understanding HVAC Design: Manual J Load Calculations

blueprint

Installing a new HVAC system is a hefty investment; depending on the type of equipment you choose to have installed, as well as the size of your home, some new systems can cost as much as a brand new car or truck! With the price tag in mind, and the comfort of your home hanging in the balance, the overall design of your system can be just as important as the installation process itself. One particularly important component HVAC designers take into consideration is called a Manual J Load Calculation.

A home’s Manual J Load Calculation measures how much conditioned air each room of your home will need to maintain a consistent level of comfort during hotter and cooler periods of the year. It does this by taking into account a number of factors, including the size of the individual rooms, different types of surfaces, the location of your home’s duct system, and even the number of appliances in your home! Manual J Load Calculations help an HVAC designer determine how powerful your HVAC system needs to be to properly heat and cool your home.

Determining which system will have just the right amount of power to maintain the temperature in your home is important, mostly because of our human tendency to overestimate our energy needs. There are plenty of newer homes on the market that have an HVAC system that is simply too powerful for the size and layout of the building. In some cases an over-powered system can be just as bothersome as an under-powered system – over-powered systems may encounter a problem called “short-cycling,” which means that the system is so big that it can heat or cool your home too quickly, causing the system to turn on and off at a frequent rate. Short-cycling can waste energy, and in some cases can shorten the overall lifespan of your system, costing you even more on top of your initial investment. Determining your home’s heating and cooling needs with the Manual J Load Calculation is a smart way to help you choose an efficient and long-lasting system for your home.

Choosing an efficient HVAC system doesn’t have to be a daunting experience. Call Home Comfort today and our team of HVAC estimators and designers will help you make the most of your heating and cooling investment.

Easy Use, Easy Maintenance: Electronic Air Cleaners at Work

Here at Home Comfort, we take indoor air quality seriously. These days most people in the United States spend up to 90% of their time indoors, and the United States Environmental Protection Agency (EPA) lists indoor air pollution as one of the top five environmental health risks we face today. With energy-efficient homes insulated and sealed tighter than ever against fresh outside air, the quality of the air inside a person’s home is often filled with far more pollutants than the air outside, even if you’re using a high-quality air filter and changing it regularly. For those who are concerned about allergens and indoor air pollutants, and would like to take an extra measure to ensure the cleanliness of the air in their homes, installing a whole-home electronic air cleaner may help.

Electronic air cleaners take the job of a normal air filter for a ducted heating and cooling system and take it to the next level. Rather than simply trapping particles in a tightly-knitted, mesh-like media, electronic air cleaners trap particles by giving them an electrostatic charge them as they pass through the filter, causing them to stick to a collection surface rather than passing through the your duct system and into your home. To see an electronic air cleaner in action, check out the video below. It will show you a demonstration of American Standard’s Accuclean™ Whole-Home Air Filtration system at work.

Besides their efficiency, electronic air cleaners have a simple cleaning process. And, since the filters are washable, you can save money in the long run rather than purchasing disposable filters every few months. If you click on the video below, you’ll see a demonstration for cleaning the Accuclean™ system:

Basically, if you can vacuum your carpets, drapes, and furniture, you can clean this air cleaner regularly with no trouble!

If you have a ducted heating and cooling system and like the idea of an efficient, easy-to-maintain air filtration system, give our estimators at Home Comfort a call. We can match the right electronic air cleaner model with your home or business.

Is My Ducted Heating and Cooling System Outdated?

Ducted System ObsoleteThat’s a valid question since it appears we are in the middle of a ductless heat pump revolution.

If you’re a homeowner that has an older ducted system that needs to be put out to pasture, you’ve probably developed some pretty respectable calluses thumbing through all the publications and articles touting the highly efficient ductless units. Nearly every advertisement shows these sleek beauties mounted in every type of room a home can have. The overall message seems to be saying ductless systems are the best choice for when that old ducted system needs replacing.

Not so fast…Before you decide to go ductless, and convince yourself you can convert your ductwork to deliver laundry to the hamper the way a suction tube at the bank delivers your deposit to the teller, you have a little more info to absorb.

While they are an excellent choice for many applications, ductless systems are not one size fits all. The typical ductless system is best suited for small apartments, room additions and retro fit applications where adding a network of ducts would not be feasible.

Installing a ductless system that is comparable in all aspects to your existing ducted system would be an expensive blow to the family budget. And the operating characteristics are vastly different from that of your current system. For a household that is accustomed to having the heating and cooling system working in a sort of out of sight out of mind manner, the ductless system’s center of attention approach will take some getting used to.

A portion of wall space in most if not all of the rooms will need to be designated as the permanent location for the air handling unit, commonly referred to as the “head.” Large rooms may require the installation of multiple heads to adequately heat and cool the space.

Choosing the best location to mount the heads may require annexing prime real estate that is currently occupied by the prized family portrait or the shadow box shrine show casing the memorabilia of your glory days. That is if you have a choice; in most cases the unit’s operating requirements dictate where the head will need to be mounted.

Okay, so maybe you’re starting to realize that ductless is not the best option for replacing your aging HVAC equipment. But you really wanted that remote control… every time you see an ad for the ductless system there’s the awesome all controlling remote.

You’ve imagined yourself standing on the couch, waving that remote control at your new ductless unit; changing the temperature with just a click of a button..Hotter…Colder…Summer then Winter..The kids and dog watching you in total amazement, so in control of the seasons within your own living room that Mother Nature herself is taking notes.

Well that’s just weird… But having a ducted system doesn’t mean you can’t have the toys, or reap the benefits of modern technology.

Today’s air handlers, gas furnaces and heat pumps from manufacturers such as American Standard are built utilizing all the latest technology. Fully communicating systems, inverter compressors, modulating gas valves, electronic expansion valves, variable speed blower motors…What’s that? You’re in technology overload… just get to the thermostat information.

Well brace yourself…Honeywell offers thermostats that give you the power to control your heating and cooling system from far beyond the limits of both the traditional remote controller and your living room…Just imagine the look of amazement from the family when you’re commanding your heating and cooling system from five hundred miles away…with your smart phone…while standing on your Mother-in-law’s couch. Okay odds are “amazement” wouldn’t accurately describe the look on your Mother-in-law’s face. But she’ll come around when you demonstrate the full array of thermostat features that can be manipulated using your laptop, smart phone or desktop computer.

Call the experts at Home Comfort Heating to learn about all the features and options available from American Standard and Honeywell. We’ll help determine the best equipment to fit your needs and budget.

We can also help you understand the applications and benefits of a single or multi head ductless system available from manufacturers like Mitsubishi.

We’ll help you determine if a ductless system is right for your home or business.
