Homeowners your hands one of the most important documents you can possess before you purchase a home! What every homeowner or potential homeowner absolutely needs to know and understand is this, you as a homeowner have ALL the responsibility to make sure your new home is going to function and be an energy efficient home.This document is written for the homeowner to understand the city inspections. This article is not referring to the third party inspection completed by a licensed Professional Home Inspector.If you are concerned about the energy efficiency for your new home the single most important item that impacts energy usage and monthly energy bills is the size of the home. The energy cost to operate your home is directly related to the size, shape and volume of your home. Home builders today are not supplying potential home buyers with two critical pieces of information you need to understand the energy efficiency of a particular home or if you are comparing the homes from two different home builders.When an engineer designs and sizes the AC equipment for a building large or small he uses a load calculation method to determine how much heating and air conditioning capacity is needed to serve the new building. The same approach and method is supposed to be used today in new homes built in Texas. The home builders in Texas have been building homes in Texas since 2001 that will not meet the required energy code standard and design guides. The load calculation step is the very beginning and most important step in building a home for energy efficiency but is not being performed by builders today. This is simply because most builders do not pay attention, understand the energy code or understand load calculations.The other problem or issue is that most homeowners have never heard about it and do not care as well. Most homeowners believe that someone else is taking care of this for them. As I stated earlier in this guide this is simply not true or being done.Homeowners Have To Take ResponsibilityHow do homeowners know that one home is more efficient than another? The method used to
understand the efficiency of a home in regards to the heating and air conditioning systems is based on a unit of energy known as a “British Thermal Unit” (BTU). I am not going to get real technical here but I will give you the homeowner the information you need to go home shopping with and it is really very simple.Three Efficiencies Regarding Home Building1. Thermal Efficiency- Determined by the home construction methods and materials
used to build the home. It is the most important efficiency in home building.2. Energy Efficiency – Measured and calculated by the conversion of energy input
(KW/BTU) into useful work output cooling/heating BTUH.3. Overall Efficiency – Is the combination of both efficiencies above. Thermal Efficiency
has a huge impact on the Energy Efficiency rating and therefore will impact the
overall efficiency of the home.As a homeowner this is what you need to know. The amount of energy required to heat and cool your home is directly related to the amount of heat gain your home experiences when it is warm outside and how much heat loss your home experiences when it is cold outside. This heat gain and heat loss is measured in BTUS. The amount of heat gain and heat loss is measured and defined on an hourly basis so the measurement is in BTUH. This stands for British Thermal Units per Hour. The higher the thermal efficiency of the home the lower the energy use is. As a homeowner you will receive a better return on investment for each dollar you spend to make your new home more thermally efficient than to build a very poor thermally efficient home and try to make up the overall efficiency with very expensive high end heating and air conditioning equipment. This approach simply does not work over the life of the home.As a homeowner you have another measurement or consideration to think about and that is the “Return on Investment” (ROI) for your money. If you to take short cuts on the home construction side and purchase very expensive high end AC equipment to make up you may cost your self a lot more money over the life of with expensive repair bills. The cost to repair the high end AC systems is very expensive.Below is a simple but real example.
- 14 SEER AC System – Replace a failed indoor fan motor. Cost= $250.00
- 20 SEER AC System – Replace a failed indoor fan motor. Cost= $1200.00The newer systems are very complicated with a lot of electronic components that are very susceptible to power problems and lightning strikes during storms. As a homeowner you need to consider this when building a new home with the least cost to maintain and operate. Homeowners need to spend their money making their home more thermally efficient and use AC system(s) rated at 14-15 SEER instead of 20 SEER systems.The Questions a Homeowner Needs to Ask a Home Builder- Mr. Home builder what is the heat gain for this home on July 15th at 3:00 PM in the afternoon?After he regains his thoughts he will probably reply with; what do you mean? This will give you a real clue here. He does not know anything about the thermal efficiency for the homes he is building!”You might want to consider a new home builder at this point!”- Mr. Home builder what is the heat loss for this home on January 15th at 3:00 AM in the morning?These are the questions that any potential home buyer should ask if they are concerned about energy efficiency and the monthly energy bill for their home. If you are a homeowner who operates on a monthly budget then energy efficiency is very important for your new home. Let us use the example below to demonstrate how the real energy efficiency of two homes should be compared.- Home A- single story with 2500 square feet of air conditioned living area, all electric home, all energy star rated appliances, and all the lighting fixtures are compact fluorescent and the high efficiency type. The home has a 5 ton 14 SEER rated AC system.- The heat gain for the home in July is 49,500 Btuh.
- The heat loss for the home in January is 72,000Btuh.- Home B- single story with 2700 square feet of air conditioned living area, all electric home, all energy star rated appliances, and all the lighting fixtures are compact fluorescent and the high efficiency type. The home has a 4 ton 13 SEER rated AC system.- The heat gain for the home in July is 44,000 Btuh.
- The heat loss for the home in January is 66,000 Btuh.Which home is more efficient? Many homeowners would choose Home A simply because it has the largest AC system and highest SEER rating of the two homes. The most efficient home is Home B. This home is larger and is being served with the smallest AC system. Even with the lower SEER rating for the AC system the system is rated at 4 tons and is able to cool the home adequately. The difference in heat gain and heat loss values is what makes home B the most thermally energy efficient. The size of the AC system does not make a home more thermally efficient. The AC systems in homes are sized to meet the heat gain and heat loss values of the home. The lower the heat gain/loss number the higher the “Thermal Efficiency” is for the home. What makes the home more thermally efficient is size, construction, direction the home faces, window type, wall construction and insulation values to name a few. The thermal energy efficiency of the home is determined by the construction methods and materials not the heating and air conditioning equipment. The AC equipment only makes a difference in the conversion of electrical energy or the conversion of fuel into useful work- cooling output (Btuh) or heating output. When the SEER rating is higher the conversion of electrical energy is more efficient and therefore the energy bills are lower for the home. A home that only requires a 3 ton AC system to meet the cooling load will be less efficient if the same home has a 5 ton system installed no matter what the SEER value is.Example:
- Home C- Has a 12 SEER 3 ton AC system that is properly sized and works properly
- Home C- with a 16 SEER 5 ton AC system will not function correctly and will make the home uncomfortable because the system will short cycle and this reduces the energy efficiency (SEER) of the AC system.Homeowners do not fall for the bigger is better sales pitch! Bigger is not better regarding AC systems EVER!Let’s talk about heating systems now. If you are building a new home, buying a new home or purchasing an existing home you need to consider how your new home is heated. The method of heating a home today is not quite as simple as it once was. My personnel first choice for heating a home is by using a natural gas or propane system. I like the warmth and feel of the gas systems. At one time it would have been considered the most economically method to heat a home. In today’s constantly changing energy markets the price of a MCF of natural gas is not always the least cost to operate. I will list the methods of heating a home in order based on cost, comfort and reliability below.The Southern Part of the Country1. Gas Heat- If the price of natural gas or propane is least expensive on a consistent basis2. Heat Pump System- If the home is total electric a heat pump system is a must for energy
efficiency.3. If the home is total electric the last choice would be electric resistive heating. This is a very
expensive choice for heating.The Northern Part of the Country1. Fuel Oil – If the price of fuel oil remains less than natural gas or propane on a consistent basis2. Natural Gas – Would be the second choice over electric heating.3. Heat Pump System- If the home is total electric a heat pump system is a must for energy
efficiency.4. If the home is total electric the last choice would be electric resistive heating. A very
expensive choice for heating.
5. In areas where wood is available and the home has a good wood heating system.
Home AC System DesignQuestions to Ask Your Builder1. What is the heat gain for the home? July 15th 3:00 PM _____________ Btuh2. What is the heat loss for the home? January 15th 3:00 AM ______________Btuh3. How many units (systems) are in the home?Recommendations
- Single Story Homes less than 2000 sq ft- Single System
- Two Story Home less that 2000 sq ft- Two Systems, One Up and One Down Stairs
- Single Story Homes > 2000 but 5000 sq ft- Need to consult with a mechanical engineer with experience with
energy efficiency designs and energy conservation. Ask for references. Suggest
someone not in relation to the AC contractor to get the best objective design and solution.
- Discuss the heat gain/losses with your AC contractor or mechanical engineer to find out
what you can do to lower these values by making changes in the design and materials for
your home.4. 6. Ask for the AC contractor’s name and for references. Talk to homeowners who have been in their home more than two years or so. This will give you a better understanding of how well the contractor designed the AC systems and how they performed in both the cooling and heating seasons.5. Ask the contractor to give you some estimates in writing to replace the indoor fan motor and the compressor for the AC systems you are considering. If you are trying to decide between a system rated at 15 SEER and one rated at 20 SEER this will help you understand what the overall cost is and what your ROI could be over the life of the system(s).6. If you are looking at purchasing a home that will require major remodeling and the heating and air conditioning system to be replaced you need to make sure you understand the following about the AC contractor you hire.- Is the contractor licensed?
- Is his licensed current?
- What level of general liability insurance does he have?
- Is his insurance policy current?
- How many technicians will be working in your home?
- Have these technicians been registered with the state? A state of Texas requirement
- Have you checked the contractor out with the Better Business Bureau?
- Ask for a copy of his license and insurance policy.
- Verify the insurance policy is current with the policy provider, this is very important.Insurance Requirements for AC Contractors Texas (Verify Requirements for Your State)Homeowners AC contractors in Texas are required to carry a general liability insurance policy in order to perform work in the state of Texas. In 2003 the state of Texas stopped requiring AC contractors to prove they have general liability insurance prior to renewing their license each year. This puts homeowners at risk all over Texas when using and hiring AC contractors. You as a homeowner have to take the initiative to verify the AC contractor you are working with has a current general liability insurance policy.- Class A license holders are required to carry a $300,000.00 policy.- Class B license holders are required to carry a $150,000.00 policy.Homeowners you need to determine if the value of your home and personnel possessions have a value higher than the required limits for the AC contractor you hire. Check with your homeowner insurance provider how this impacts you as a homeowner in the event your home is damaged or destroyed because of poor workmanship or faulty equipment. You may want to ask your contractor to provide a higher level of liability insurance before starting work in your home.Homeowners do not become a victim of an unlicensed and uninsured AC contractor!Third Party Inspections and ResourcesMany cities and homeowners are using third party inspectors today. As a homeowner you are ultimately the responsible party to make sure your home and your investment is protected. Just because someone is a third party inspector means they are any better than the local city code official. I would recommend that you take the time to talk with two or more inspectors to find out who you believe is the best one that can help to insure you receive the best value for your money and the best AC system for your home. I always recommend that homeowners talk to their neighbors, friends and family to find out if they can offer you some good advice or to help steer you away from someone who does not understand what they are doing. A few simple phone calls or few minutes talking to someone can save you thousands of dollars and headache.SummaryHomeowners if you are considering purchasing a new home you have a lot on your mind. The AC system(s) for your new home are a very important piece of the equation to being satisfied and happy with your new home. We covered a lot of information in the “The Home Buyers Guide to AC Systems” and I believe you probably have learned some helpful tips and a whole lot about heating and air conditioning. Do not let this overwhelm you but simply take it in a step by step approach when deciding what type of heating and air conditioning system for your home. If you take the information you have learned and start to discuss it with home builders and AC contractors you will find out they are not going to be very open and willing to work with you. When home builders and AC contractors know they are doing business with a potential homeowner that knows something about AC systems they become a little uncomfortable. This will go to show you that home builders and AC contractors have had it their way for a long, long time. It is time for homeowners to receive the best AC systems for their new homes. You can do this and be very
successful at the same time.Good Luck with Your New Home or Next AC Project!

If you travel frequently or travel a lot then you must have realized the importance of travel planning. A well planned trip really gets you your money’s worth. You are aware of your schedule, plus you are not wasting your time in figuring out (at the last minute) what to see, what to do, where to eat, etc. But still a lot of people travel with vague plans and without a complete picture. A lot of people say to me that travel planning is hard and time consuming and that if they were to wait for a travel plan then they would not be able to travel at all.I disagree with all of them. Yes, it takes time to plan a trip but whats the point of traveling to another country or city if you are not going to see the best sites, taste the local food, or experience the top activities. Following are some of the tips that you can use to plan a near perfect trip for yourself.First of all, zero out on a location where you would like to travel, it may be another city, state or another country.Second, Why you would like to go there? Maybe some friend or family member went there and were full of praise or may be you read about it on internet or magazine or saw it on TV. Realizing WHY you want to travel to a particular location will help you plan the trip properly. For example, you may want to travel to the New York city to see the skyscrapers, or/and see Statue of liberty or/and may be visits the Museums.Third, How long i.e. How many days you want to spend in the new place.Once you have decided WHERE you want to go, understand WHY you want to travel there and decided HOW long you want to visit for, you can then begin preparing your itinerary.You should start by asking your friends, family & co-workers about the destination that you have selected. If they have not been there, you should ask if anybody they know have traveled to that place. If yes, then don’t be shy of talking to that other person about their experience. Realize that people love to talk about their trips. This way you would learn a lot and maybe make a new friend in the process.You can watch YouTube videos or watch Travel Channel to get ideas about the place you would like to visit.Further, Google is your friend, you can search for the location to get tons of information about any place. There are thousands if not millions of Travelogues written virtually about all places on this earth.Tripadvisor.com is an excellent site to research about any destination. You can ask questions, read about other’s experience etc. But the research on internet is time consuming and you should be diligent.Lastly, you can even read the travel books, city guides by Frommer’s, Lonely Planet and Fodor’s. These are very well written and cater to all level’s i.e. Newbies, repeat, expert etc.All these will tremendously help you plan your ideal trip and make the most out of it.To get more tips and to see how Travel Planning Helps visit Travel Haggler’s Blog.
