Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation, as HVAC&R or HVACR or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers).

If your HVAC equipment is more than 10 years old or not keeping your house comfortable, have it evaluated by a professional HVAC contractor. If it is not performing efficiently or needs upgrading, consider replacing it with a unit that has earned the ENERGY STAR. Depending on where you live, replacing your old heating and cooling equipment with ENERGY STAR qualified equipment can cut your annual energy bill by more than $115. But before you invest in a new HVAC system, make sure that you have addressed the big air leaks in your house and the duct system. Sometimes, these are the real sources of problems rather than your HVAC equipment.
Also, have an energy-efficiency professional come to your home and perform an energy assessment. This assessment could be either conducting a walk-through of your home with a clipboard or performing a thorough audit, pressurizing your home with a blower-door test to detect energy leaks. You may qualify for state discounts or rebates to have insulation installed in your home. Some utility companies also subsidize the cost of these energy efficiency assessments.

Finally, air conditioning and heating maintenance, provided on a regular schedule, can prevent many air conditioner or heater breakdowns thereby preventing the need for you to call an air conditioning and heating repair person for central air conditioning troubleshooting. Maintenance can save you lots of money in the long run but even so, problems can still occur.
We moved into a new home and had issues with the heating ducts in one of the rooms. We called HVAC based on other yelp reviews. Overall, everyone we dealt with were friendly, professional and knowledgeable: From the people on the phone managing the schedule to the those performing the work in our house. The day before the scheduled work we asked if additional work could be done (clothes dryer duct cleaning), which they were able to accommodate. The people working at the house were on time, very polite, took great care to keep the house clean during the entire job and explained everything when they were finished. I will certainly use HVAC again.
Many homes in Portland don't have air conditioning of any kind. Whether your home is decades old or just a few years, the wisdom is that the moderate climate of Portland will be enough to keep you comfortable. In fact, when building a home, you typically need to request air conditioning installation from your home builder. With an average of only two weeks or so worth of days that hit 90 degrees, many people simply can't justify the expense. Of course, HomeAdvisor does see quite a few Portland air conditioning installation requests, simply because so many homeowners don't have central air. If you've decided it's time to indulge yourself or have recently moved into a Portland home without air conditioning, we can help you find a contractor who will help you with any or all of your A/C needs.

The heat pump gained popularity in the 1950s in Japan and the United States. Heat pumps can extract heat from various sources, such as environmental air, exhaust air from a building, or from the ground. Initially, heat pump HVAC systems were only used in moderate climates, but with improvements in low temperature operation and reduced loads due to more efficient homes, they are increasing in popularity in cooler climates.

In 1758, Benjamin Franklin and John Hadley, a chemistry professor at Cambridge University, conducted an experiment to explore the principle of evaporation as a means to rapidly cool an object. Franklin and Hadley confirmed that evaporation of highly volatile liquids (such as alcohol and ether) could be used to drive down the temperature of an object past the freezing point of water. They conducted their experiment with the bulb of a mercury thermometer as their object and with a bellows used to speed up the evaporation. They lowered the temperature of the thermometer bulb down to −14 °C (7 °F) while the ambient temperature was 18 °C (64 °F). Franklin noted that, soon after they passed the freezing point of water 0 °C (32 °F), a thin film of ice formed on the surface of the thermometer's bulb and that the ice mass was about 6 mm (1⁄4 in) thick when they stopped the experiment upon reaching −14 °C (7 °F). Franklin concluded: "From this experiment one may see the possibility of freezing a man to death on a warm summer's day."
Next, consider the age of your unit. Remember, as we mentioned earlier, that the average life of a furnace is around 15 to 20 years. In some cases, during the installation process, your licensed and trained technician will write down the installation date right on the unit. If not, you can check inside the chamber door for a metal identification plate containing the serial and model numbers. You can then call the customer service line of the manufacturer and ask for the manufacture date of the unit.
Your system is 10 - 15 years old: Follow this simple rule of thumb from Energy Star—if your current system is over 10 years old, it's time to start looking into an HVAC replacement. Most HVAC systems last for about 15 years, so there’s no immediate need to replace yours if it’s still functioning properly. But by doing your research now, you’ll know just what you want to do should your HVAC system suddenly stop working properly.
Restoring or replacing an aging unit can get expensive. Invest in a new model if your utility bills are rising and you notice uneven air flow and temperatures throughout your property. If one room is cooler than another, consider a total replacement. If the air conditioner is relatively new and still within its age range, it's more cost-effective to get a contractor to repair it.
The contactor (relay) and start/run capacitor(s) (see illustration below) fail most often and are inexpensive. So it’s a safe bet to buy and install those parts right away, especially if your air conditioning service unit is older than five years. The condenser fan motor can also fail, but it runs about $150 — hold off buying that unless you’re sure that’s the culprit.
