I hear a lot of talk about high-efficiency heating systems. How do you determine a heating system’s efficiency?

One indiciator is Annual Fuel Utilization Efficiency (AFUE). All heating equipment manufactured after 1980 has been required to have a label indicating its AFUE. The AFUE ratio is a measurement of a heating system’s seasonal efficiency, taking into account how well the system performs over an entire season of starts and stops. Modern heating systems can range in efficiency from 81% to 95%. If your system’s AFUE is lower than this range, talk to us about your replacement options.

If I’m looking to replace my system, how many bids should I get?

It’s really up to you, typically you’re told 3. Sometimes getting a bid will be a good indicator of the kind of company you’re working with, that’s why we guarantee reasonable rates and quality service with careful attention to details.

Is A Geothermal Heat Pump Difficult To Install?

Most units are easy to install, particularly when they replace another forced-air system. They can be installed in areas unsuitable for fossil fuel furnaces because there is no combustion, thus no need to vent exhaust gases. Ductwork must be installed in homes that don’t have an existing air distribution system. The difficulty of installing ductwork will vary and should be assessed by a contractor. Another popular way to use geothermal technology is with in-floor radiant heating, in which hot water circulating through pipes under the floor heats the room.

Is annual maintenance necessary?

Yes! In our area, comfort systems work hard; and just like anything that might be operating virtually non-stop for months on end, a little regular maintenance goes a long way. Think about the car you drive daily -  without the regular maintenance of a tune-up, you lose efficiency (Miles Per Gallon) and money (to replace those gallons used).

Regularly-scheduled & performed tune-ups keep your system working at their peak efficiency, and can extend the life of your equipment by giving our technicians a chance to potentially catch minor problems and signs of wear before they turn into major trouble down the road. An annual tune-up also protects your family/building occupants by helping prevent life & health-threatening conditions from occurring, likecarbon monoxide poisoning for example.

Is it OK to mix and match air conditioning components of different efficiencies? Just because my compressor is on its way out, does it mean I have to replace my indoor unit as well?

It’s never a good idea to mix and match a/c components of different SEER. You might save money initially by replacing only your outdoor unit with one of the new mandated 13 or higher SEER compressors and hooking it up to your 10 or 12 SEER system. However, it just doesn’t make sense in the long run. It’s like buying a brand-new stereo set and hooking it up to your old, antiquated speakers. You’re just not going to get your money’s worth in terms of comfort and efficiency. You’re better off paying a little extra up front because you’ll be saving a lot more over time. At Princeton Air, we have the expertise to help you choose the right efficiency system for your home. For a no-obligation evaluation, call us.

I’ve heard that they are phasing out the old A/C refrigerant in favor of a new, more environmentally friendly version.

That’s right. As of January 2010, cooling system manufacturers can no longer make equipment that uses R-22, commonly known as Freon. R-22 has been found to damage the Earth’s ozone layer, which is a key factor involved in global warming. By 2020, R-22 will no longer be produced. The coolant that has replaced R-22 is known as R-410A, which was developed by the Allied signal company in 1991. Several companies have since trademarked their own version of R-410A, including Carrier (Puron®), Honeywell (Genetron® AZ20) and Dupont (Suva® 410A). Years of commercial use and testing have proven that, in addition to being more environmentally friendly, R-410A is superior in performance and energy efficiency to Freon.

My home does NOT have forced-air heating, and, therefore, there is no ductwork. Can I still get central air conditioning?

Absolutely! Today simple, ductless air conditioning options make it possible to install a quiet, efficient air-conditioning system in your home even if it doesn’t have ductwork.

Ductless air-conditioning systems consist of one or more indoor air-distribution units linked by refrigeration lines to an outdoor compressor. These flexible “hoses” can be positioned inside your walls and ceilings with a minimum of inconvenience. Installing ductless air conditioning costs a little more than standard central air-conditioning systems but much less than the cost of installing ductwork and a central air-conditioner.

My home has a forced-air furnace but no air conditioning. Can I add central air?

You bet! We can mount a cooling coil on top of the furnace and install a condensing unit outside. For a no-obligation evaluation, call us today.

My thermostat is suddenly reading Celsius. What can I do?

Either find your owner’s manual to get it back to Fahrenheit, or call us to help you out. Some of the older models will read Celsius if you accidentally push two buttons by mistake.

On mild winter days my furnace runs in short blasts and my home alternates from being too hot to being too cold. How can I fix this?

Installing a new furnace with 2 levels of heat and a variable speed motor is a good solution. These “smart” motors automatically adjust the volume and speed of air based on your home’s temperature requirements.

There will be fewer on/off cycles, smaller temperature swings, consistent, even heat, and lower fuel bills.
