BTU What is it?

A BTU by definition is the amount of energy it takes to change one pound of water one degree. BTU Stands for British Thermal Unit. It is a measure of heat content of an appliance. The more btu’s the higher the available heat. Btu’s are commonly used to give a rating of size to many different appliances including furnaces, air conditioners barbeque grills fireplaces etc.

When you are looking at appliances, btu’s are important, because they tell us how much heat is available for our use. Low btu’s in grills for instance, means poor cooking performance, Some grills have all the flash but no real cooking ability which leads to our dissatisfaction. Low btu’s in fireplaces means small flames. Small flames mean low heat output and low romance factor. Btu’s in some appliances must be de-rated by the efficiency of the appliance. For example, in a furnace that is 92% efficient you only get 92% of the heat produced by that appliance. That’s why having the furnace and air conditioner properly sized is so important. No Guessing Allowed. If your furnace is too small you’ll be cold and if its to big you’ll be hot when its on and cold when its off. Cooling units won’t keep up if they are to small, or will not do proper humidity control if they are too big, you want it cool and dry. Not cold and clammy.

I’ve heard things about VOC’s , what is that?

VOC stands for volatile organic compounds. They are released as gases from things like new carpet, paints solvents, furniture and household cleaning agents. They can adversely impact your indoor air quality.

Sometimes I see advertisements on TV for air cleaners. How do they rate?

They are good for only one room and then only the fan forced units. For more information see Consumer Reports February 2002 where they tested 16 different air purifiers, or a second article in October 2003. Honeywell produces whole house air cleaners that are far easier to care for than stand alone units. These systems work with your existing furnace and duct work. They are very high efficiency and will work with most existing systems. For more information you can contact our store.

Should I turn off my heat pump when it gets real cold?

There is no clear cut answer here. It depends on how old your unit is and how efficient it is. Units produced from about 1985 on are probably going to work just fine to below zero weather conditions. Trane does not recommend turning their units off anytime. By my calculations they still produce more heat than they consume in electricity to well below zero.

How often do I need to change my filter?

All manufactures recommend you change filters monthly. However if you have a thick filter you may not need to change it as often.

Can I double my filters up so they are thicker?

NO. they create to much restriction to the air flow and may damage your system. If you want better filtration purchase the pleated filters.

When should I get my air conditioning tuned up?

Basically any time in the season is a good time. When is not as important as if. Just make sure that it gets looked at least once each year.

What is Customer Assurance Pricing?

CAP is a way that we control pricing to our customers. It is based on a repair, rather than on time and materials. This way we insure every customer gets the same price and the best value.

What do port to port charges mean?

It means that you are charged from the time a technician leaves their last job till they get to yours. At Terry’s you’ll NEVER be charged from port to port, or for time to run down the correct parts for your system.

Should a Technician leave the old parts with me?

Generally we show the customer the defective parts and dispose of them for our clients. The old parts are in fact yours, and you can do with them as you see fit. The exception is in warranty replacement parts, they must be returned to the manufacturer.
