Tips for Furnace Repair and Replacement

How do you know if it is time for furnace repair, or if you should replace the whole hvac system? Here are some tips to help you know if you can fix the existing unit or if you should consider purchasing a new one.
If the furnace is older than 15 years, it is time to call a professional to perform a thorough check-up and to see if there are problems that need to be fixed. The same applies if the air conditioner or the heat pump is older than ten years. A professional expert can perform an overall check to see if the unit should be replaced, if there are any repairs that need to be done and if there are ways that the performance of the unit can be improved. Even if you do not need to buy a new unit or to replace the furnace, any heating and cooling unit that is older than ten years should be checked professionally. If you need a professional in your area, check out Champs HVAC.
If some of the rooms in the house feel warmer or colder than others, if you need to keep fixing regular problems in the system or if you have noticed higher energy bills in the recent past without an actual reason, it might be time to replace the furnace. If you replace it with a newer model that has the government’s “energy star”, you can end up saving money as the new models are much more efficient and can save as much as 20% in your air conditioning and heating bills. If you do not need to buy a new heating and air conditioning unit, but are considering investing in a new furnace, an energy star –labeled furnace can save around 5% in your heating bills if it is installed professionally. Make sure it includes a thermostat you can program to switch the system on or off.

Understanding HVAC Basics

Heating, Ventilation, and Air Conditioning (HVAC) refers to a system that combines both heating and air conditioning for indoor or car use. The mechanism behind it is simple: It contains an air conditioning aspect that converts water to vapor to provide the cooling effect, and a heating system that heavily relies on heat pump or furnace to supply constant heating that is perfect during winter seasons. The way heating operates is that it has a warming exchange where air is converted to warm air.

To understand the refrigeration and heating activities of an HVAC, picture out an air being sucked into the system. The heat elements of this air get removed and only the cold part is filtered in. HVAC has a compressor that converts this to hot coolants so that when they reach the coils, all heat is gone and what's left is condensed liquid. This is then absorbed by the expansion valve where it turns into cold vapor.

As the vapor passes through evaporator coils, it picks up heat which subsequently produces cool air and is distributed throughout the enclosed space. The heating process is relatively simple. The two main components responsible for the delivery of hot air are the heat pump and furnace. They simply sucks in and converts air into warm air to be used in homes or offices.

One type of HVAC system is the furnace and condensing system. In this type of equipment, air is sucked from external sources using ERV and HRVs that substitutes HVAC air with fresh external air from the environment while attempting to recoup energy in the system before releasing the dirtier air that has already been processed. When purchasing an HVAC, make sure there is an efficient system that makes use of electricity and natural gas in pumping out hot and cold air. When having that system installed, be sure to hire a licensed professional. Many companies like Heater Repair Atlanta, offer professional service at reasonable rates. Hiring a pro not only makes sure the job is done right but it also protects the warranty on your new equipment.

HVAC Ductwork

Howdy readers! I found some great information that I just had to share when I was checking out one of my buddy's recent posts. The information is on ductwork. Now I recently did some renovations to my home's heating and air system so this topic was fresh in my mind. We installed a geo-thermal heat pump and let me tell you I am very excited about my home going green! We also upgraded the insulation and looked at various ways to improve the energy efficiency of our home as a whole. Thankfully our ductwork didn't have any leaks and was well insulated so it didn't require much updating. However, for many older homes faulty ductwork can be a big drain on the heating and cooling system. If you haven't had your air ducts cleaned recently then I would highly recommend doing so. Just be careful and make sure that you hire a reputable company, otherwise you could end up with a bigger problem. The last thing you want is some makeshift duct cleaning machine punching holes in your ductwork so that you require an even larger expense. If you want a great resource on how to care for your ducts check out this page: Proper Ductwork Maintenance . This is one of the best information sources on the topic that I have ever found. It is by one of the hubpages author's that I have mentioned before; she writes lots of good stuff. OK folks that's it for today, check out those links and learn some great information.

Winter Heating

With the recent cold front that has crippled the eastern United States many people have had to find creative ways to stay warm. While most homes have central air units, the cost to heat in times like these can cause consumers to look for other heating options. Many people have turned to space heaters as a way to save money. There are a variety of different types of space heaters that are available at most retail stores. These include, ceramic heater, oil filled radiators, and heat dishes among others. These offer homeowners the opportunity to heat a single room in the house while keeping the general thermostat at a lower temperature to keep costs down. Do these work? Yes they do. They can often reduce a winter heating bill dramatically. Check out this article if you are looking for other ways to reduce winter heating bills. Another important aspect of staying warm in the winter is making sure that your home central heating unit is operating efficiently. Many heating and air companies offer system checkups which can diagnose any problems before they cause full system failure. The last thing you want in times like these is to wake up freezing because your primary heating system failed. In Atlanta heating and air companies have seen a large increase in system failures due to the construction boom of the early and mid 2000's. Construction debris makes its way into heat pumps and exterior units which can be a ticking time bomb for a central air unit. Take the time to have your home's central air checked out to make sure your system is healthy.
