How HVAC Systems Work

Heating, ventilating and air-conditioning (otherwise known as HVAC) systems are often referred to as climate control. They regulate temperature, air quality and humidity. Heating and cooling systems systems were first used in commercial buildings, but are now routinely being installed in domestic homes.

An HVAC system has two main parts - an external condenser and in internal evaporator coil. These two components work in conjunction to cycle cool, dehumidify, or warm air through the HVAC ducts in your house. It is possible to get the two components in a single external unit, depending on your specific needs. Your HVAC installation company will tell you if this is an option for you.

Compared to traditional heating and cooling methods, HVAC systems are easily regulated and are more efficient. They can be installed with "zonal" control, which allows you to precisely regulate the climate in specific areas or rooms. Central air systems are more expensive up front than traditional heating and cooling methods, however the cost can be recovered in the long run because of an heating system's energy efficiency, versatility and ability to be upgraded.

HVAC systems have seen a marked improvement in the development of efficiency within the past decade. Using new gas refrigerants, modern climate control systems are environmentally friendly and efficient. In fact, many commercial buildings and homes are having their HVAC system customized to fit their specific needs.

You can maximize the energy savings by taking a few steps to optimize your central air system and reduce its energy consumption. First, you can insulate and weatherize your home. If your home has insufficient attic insulation or poor or old window construction, heat will be lost. This means your HVAC system will have to work harder to produce more heat. It is important to make sure your home is expertly insulated to get the most out of your heating and cooling system.

Remember that turning the thermostat down even one degree can have a dramatic impact on your energy bills. You may elect to install a thermostat that can give you precise control over the climate in your home during scheduled times, or thermostats that control specific rooms.

Make certain to replace the air filter on a regular basis, usually once a month. Keep exterior components of the climate control free of dust and debris to prolong its life.

Be sure to have a qualified heating and cooling professional install, inspect and upgrade your temperature control equipment. Inspections should take place once a year to clean the system and make sure it's running properly. HVAC professionals will be able to diagnose problems and fix issues such as excessive humidity, loud noise and improper temperature.

Energy bills are constantly skyrocketing. Take control of your energy consumption without compromising on the comfort of your home by having a qualified heating and cooling company install an HVAC system.

HVAC Troubleshooting

Did you know that the third biggest investment for the average American is their air conditioning/heating unit? With prices in the thousands of dollars, most people want to be sure that their HVAC unit will provide the comfort they seek, use the least amount of energy possible, and be relatively trouble-free. But even with new units, there are bound to be some issues that arise with your AC/heating unit, but not everything that happens requires an expensive visit from a professional. Before you call in the AC guy, you may want to check out HVAC troubleshooting guides available on the Internet.

There are several HVAC troubleshooting sites from which to choose, and you may even like to read over more than one of them to see if the advice is consistent. Even if you do need to call in a repairman, it certainly pays to understand the basics of how your HVAC system works so you can converse intelligently with the service technician when he or she arrives.

HVAC troubleshooting guides can also help keep you from getting ripped off. Of course, most service companies are quite legitimate and honest, but there are probably some out there that might choose to take advantage of uninformed consumers, so having a reasonable knowledge about your product is always a good idea. The more informed you are, the less likely it is that you will get taken for a ride, so take care of that expensive HVAC system, but look into understanding as much as you can about it yourself via online or other HVAC troubleshooting guides.

These guides can also help you find local, reputable repair technicians, answer questions that you have, provide information and reviews of books on the subject, give you the contact information for professional HVAC organizations, and so on.

Do You Need a New Heating and Air Conditioning System?

When at home, your personal comfort is important. No matter the conditions outside or the season, you should be able to adjust your HVAC system where necessary so you can relax at the ideal temperature. However, not all situations are ideal - occasionally you'll hear knocks and pings from your heating and cooling units, and maybe nothing happens when you try to adjust the dials. Your first thought may be to replace your HVAC system altogether, but consider for a moment that repairs are all you need in order to feel cool or warm in your home again.

Do you need to replace your air conditioning or heating system? Here are some things to consider before you make a final decision.

1) How old is your unit? Whether you have had a home built or bought an existing one without making any major renovations, you should have a good idea of the age of your HVAC system. If you are experiencing problems after only five or seven years, you can estimate that problems are related to faults during manufacture or with the initial installation. A full replacement may not be required in this situation, but you may want to have an HVAC expert take a look to determine it.

2) Have you recently weathered any bad storms? If you live in an area susceptible to hurricanes and tropical storms, or high winds, the damage eventually shows up in your equipment. Leave your outside unit unprotected, and you risk problems in the future. If you find your heating or cooling isn't as quick to start after a bad storm, you will want to assess the damage before budgeting a new system.

3) Does it cut off abruptly, or not start up at all? The more frequently you encounter serious problems is perhaps your best indicator that you need a new unit. First, check to see if any warranties are attached to your current system and find out what you need to do to get a replacement. If you have considered a more energy efficient model for replacement, you may be eligible for tax credits. Talk to your HVAC serviceman for options.

When the air suddenly shuts off, it may not necessarily be a sign that you need a new system. Know your unit and listen carefully for problems, and you can determine for yourself the next steps to take. In some cases, only minor, inexpensive repairs may be needed to keep you comfortable.

Is it Time to Replace Your HVAC System?

When extreme weather plays havoc, it's nice to know you can return home and make yourself comfortable with a solid heating or air conditioning to maintain a good room temperature. Unfortunately, while most top HVAC units can last for years, they won't keep you cool or warm forever, and one can only hope the system doesn't crash at an inopportune time when you really need to beat the heat!

Homeowners tend to have their HVAC units serviced just before an anticipated change in weather. As winter approaches, it's natural to make certain the system can hold up when it snows and freezes outside, and in the summer the same system should cool you down on triple-digit days. If you suspect problems, however, it may be time not to just call for repairs, but replace major parts of your HVAC system. Keep an eye - and ear - out for these signs:

1) Noise. This goes without saying. If you hear disconcerting and loud knocks or pings every time you adjust your thermostat, or even when you've left it alone, it's time to look into replacement rather than repair.

2) Time. Furnaces and AC units do have a shelf life. Keep track of when such purchases are made in your home - air conditioning units tend to last about ten years, while a good boiler or furnace around fifteen. You definitely don't want to overwork either of them beyond their capability, as it could lead to greater problems.

3) Bills. If you've run your systems no differently than you have in the past but notice significant increases in your energy bills, it could mean problems with the HVAC. As units age, they tend to work less efficiently and become leaky. This in turn may cause the unit to work harder to maintain temperature, which runs up the bill. Keep an eye on what you spend; when it gets to be too much it's time to invest your money in a new unit.

For a comfortable home, no matter the time of year, it is important to notice changes in the way your HVAC units work. What starts as a small ping could signal a louder groan when you realize you waited too long to make a simple repair.
