Will Thanksgiving Turkey Really Make You Sleepy?

Wednesday, November 26th, 2014

We’ve all heard it before: you feel so sleepy after a Thanksgiving meal because of the main event: the turkey. For years, people have credited extraordinary levels of tryptophan in turkey as the reason we all feel the need to nap after the annual feast. But contrary to this popular mythology, tryptophan is probably not he largest responsible party for your post-meal exhaustion.

Tryptophan is an essential amino acid, which means it’s something that our bodies need but do not produce naturally. Your body uses tryptophan to help make vitamin B3 and serotonin, which is a neurotransmitter that sends chemicals to the brain to aid in sleep. But in order to get this essential amino acid, we have to eat foods that contain it.

Turkey has somewhat high levels of tryptophan, but so do many other foods, including eggs, peanuts, chocolate, nuts, bananas, and most other meats and dairy products. In fact, ounce-for-ounce cheddar cheese contains a greater amount of tryptophan than turkey. In order for tryptophan to make you feel sleepy, you would have to consume it in excessive amounts, and serotonin is usually only produced by tryptophan on an empty stomach.

The truth is, overeating is largely responsible for the “food coma” many people describe post-Thanksgiving. It takes a lot of energy for your body to process a large meal, and the average Thanksgiving plate contains about twice as many calories as is recommended for daily consumption. If anything, high levels of fat in the turkey cause sleepiness, as they require a lot of energy for your body to digest. Lots of carbohydrates, alcohol, and probably a bit of stress may also be some of the reasons it feels so satisfying to lay down on the couch after the meal and finally get a little bit of shut-eye.

If you feel the need to indulge in a heaping dose of tryptophan this year, go ahead! Turkey also contains healthy proteins and may even provide a boost for your immune system. Here at Purl’s Sheet Metal & Air Conditioning, we hope your Thanksgiving is full of joy and contentment this year. Happy feasting!

How Heat Pump Efficiency Ratings Are Determined

Friday, November 21st, 2014

Homeowners are more concerned than ever today with energy efficiency in their homes. Manufacturers of heating and cooling systems have responded with the production of new high-efficiency units that produce superior levels of comfort along with reduced energy use. When you are considering a heat pump for your home heating in Fresno, you should examine the two ratings that will tell you how efficient a particular unit is: HSPF and SEER. For more information to help you select, size, and install a heat pump, contact our professionals at Purl’s Sheet Metal & Air Conditioning.

HSPF (Heating Seasonal Performance Factor)

HSPF is the efficiency rating for a heat pump when it is in heating mode. The number is a ratio of the amount of heat the unit generates (in BTUs, British Thermal Units) to the amount of electricity consumed (in watt-hours) as averaged over a season of heating. The higher the number, the more efficient the heat pump is at converting electricity into heating power. Many heat pumps have HSPF around 10 or 11; they are somewhat less efficient in heating mode than in cooling mode, but for the winter climates in Fresno they are usually sufficient for quality warmth.

SEER (Seasonal Energy Efficiency Rating)

SEER measures efficiency when a heat pump is in cooling mode; it is the same efficiency measurement used for standalone air conditioning systems. SEER is a ratio of the amount of heat the unit absorbs from the indoors (in BTUs) to the electricity in watt-hours, measured over a season. As with HSPF, the higher the number, the more efficient the unit. Heat pumps often have SEER of 14 or greater, and are effective for combating almost any level of outdoor heat—provided the system received professional installation.

The HSPF and SEER of a heat pump are only two factors that go into the selection of a heat pump for a house. A system can have high efficiency, yet still not work well for the home’s comfort needs. To make sure you receive quality cooling and heating from a heat pump, contact the skilled technicians at Purl’s Sheet Metal & Air Conditioning to handle the installation job. Call us today to arrange your heat pump service in Fresno.

Christmas Light Parade 2014

Wednesday, November 19th, 2014

The 21st Annual Madera Light Parade is scheduled for Thursday Dec 4, 2014. The annual light parade is a tradition in Madera that begins the Holiday Season with a spectacular Christmas celebration of lights. Every year the event is hosted by the Madera Kiwanis Club and the Downtown IMG_7531_1Association.

The light parade began 21 years ago as a procession of farm equipment and tractors down historic Yosemite Avenue in Madera, CA. It was a great way to celebrate the end of the harvest and begin the Holiday Season. Today, the parade route continues down Yosemite Avenue and still includes tractors and harvesters as well as fire trucks, cars, semi-trucks, flatbed trailers and just about anything else you can put lights on. There is only one qualification to enter … each vehicle must have a minimum of 100 lighted Christmas lights. Madera residents line the streets of Yosemite Avenue and cheer for their favorite entries. Spectators can view the parade and wander through downtown business locations.

Purl’s Sheet Metal will be entering the parade again with their fleet of antique fire apparatus decorated and loaded with Purl’s Sheet Metal employees and families. We partner our entry with our friends from Warnock Food Products of Madera with a total entry of 6 to 7 antique fire engines. It is a great evening for us to bundle up and barbeque hot dogs, drink hot cocoa and sing some Christmas carols. The Purl’s Sheet Metal & Air Conditioning fleet includes, 1979 Crown Fire Coach Pumper, 1951 American La France Pumper and a 1948 American La France Aerial Ladder Truck.    IMG_7541_1

The parade begins at 6:00 pm and also offers tickets to the wine and hot chocolate stroll through downtown businesses with appetizers and wine tasting from more than 9 local Madera Wineries. Contact the Madera Chamber of Commerce for tickets.

What Does the AFUE Rating on a Furnace Mean for My Heating?

Friday, November 14th, 2014

The energy efficiency of the furnace that keeps your house warm is one of the most important things to know about it. You can use it to estimate how much a furnace will cost to run, and it also serves as an early warning of repair issues should the furnace start to create higher heating bills than normal.

Central furnaces, whether gas or electric, have their efficiency measured in AFUE, an acronym for “Annual Fuel Utilization Efficiency.” Understanding how AFUE is measured will help you better understand your furnace. It will also caution you about when to call for repairs or schedule a replacement for the furnace. When you need expert service for your furnace, call on a highly-trained team with a long history in the HVAC industry in Fresno with heating: Purl’s Sheet Metal & Air Conditioning.

What the AFUE Rating Means

Annual Fuel Utilization Efficiency is expressed as a percentage. This percentage is the amount of energy put into the furnace that it converts into heating power, as measured over a year. The larger the percentage, the more fuel is turned into heat and the less is wasted as exhaust. For example, if a gas furnace produces on average 90 BTUs for each 100 units of natural gas that it burns, then it has an AFUE of 90%.

The Federal Trade Commission requires that manufacturers of furnaces include AFUE ratings on all new units. A non-condensing furnace must have a minimum of 78% AFUE (unless designed for a mobile home). The Department of Energy has new requirements for furnaces that are set to go into effect on January 1, 2015: all weatherized gas furnaces must have 81% AFUE after this date.

However, many furnaces score much higher AFUE ratings than this. High-efficiency furnaces often rank above 90% AFUE. Electrical furnaces are also extremely fuel efficient, but electricity is usually a more costly energy source. If you are planning to have a new furnace installed, you will need assistance from heating and cooling experts to find the right balance of efficiency and cost to fit your home and budget.

As long as your furnace receives regular annual maintenance from skilled technicians, it should keep 95% of its efficiency for most of its service life. If you notice a spike in your heating bills, it can mean your furnace needs repairs or it has reached a point where it is losing efficiency due to age. In either case, call for furnace professionals to look into the issue and see what needs to be done.

Purl’s Sheet Metal & Air Conditioning has many decades with residential furnaces in Fresno. Whether you need new installation, maintenance, or repairs to protect your home’s heating, you can count on our services seven days a week.

What’s at Risk if I Try to Install a Furnace on My Own?

Friday, November 7th, 2014

We understand that many people in the Central Valley have strong “do-it-yourself” drives when it comes to home improvements and repairs. However, if the home improvement that you need to undertake is installing a new gas furnace, you absolutely do not want to tackle the job on your own, or even hand it over to a team of amateurs. There are some very good reasons that furnace installation is a job for professionals and professionals only.

It’s easy to locate experts in home heating in Fresno who can install a new furnace for your home: call Purl’s Sheet Metal & Air Conditioning today and speak to one of our team, and we will help schedule a new installation that will give your household many years of warmth.

The Risks Involved In DIY Furnace Installation

The most important reason you should leave furnace installation to the professionals is that attempting the job yourself can be flat-out dangerous. Gas-powered furnaces connect to the gas main that enters your house, and trying to work on this line can expose you to toxic and combustible gases. In many jurisdictions, it is illegal for anyone except a licensed professional to work on any appliance connected to the gas main. Most furnace manufacturers also require that only professionals handle the installation job. Don’t take any risks of fires or exposing your family to carbon monoxide.

Aside from the potential physical dangers of DIY furnace installation, the necessary work is simply too precise and requires too much special equipment for anyone to handle it correctly unless they have years of training and access to high-end tools. Custom-cutting for the gas pipes alone is a technical skill that goes beyond do-it-yourself tactics. If you are planning to install a higher efficiency furnace for your home, modifications to the ductwork are often necessary, and this needs professionals to handle; trying this on your own could deliver you a furnace that doesn’t vent correctly or fails to distribute air to the rooms.

So leave aside any ambitions about installing a furnace yourself. The risks are too high. Professionals will handle the installation correctly so that the new gas furnace works as it should and will continue to do so for many years. And they will do the job in only a fraction of the time it might take amateurs.

Purl’s Sheet Metal & Air Conditioning has served the community since 1952. We are headquartered in Madera, CA, which Forbes recently listed as one of America’s Booming Small Cities for 2014, with a job growth of 25% over the last fourteen years and a personal income growth of 22%.
