I have this new lipstick that you have to apply gloss over it in order for it to work, i have to say that it has been beautiful… With the gloss over top of my lipstick it has been lasting all day long; However if you do not apply the gloss at all while in the day the lipstick will start to wear off & eventually will not be on anymore, then even when the lipstick starts to wear off you can see it, & it’ll look spotty. I like to think of the Heating & Air Conditioning system in the same way. If you do not get a tune up at least once a year you are doing a disservice to your Heating & Air Conditioning system… A tune-up helps your system to keep running. Just like the gloss helps your lipstick to stay on the whole time, and so it would be the best idea to receive a tune up at least once a year; That is only spending $75 on your Heating & Air Conditioning tune up once per year. If you get a tune up you may not even need to pay for service throughout the rest of the year… You may even get blessed & not have to need a service on your Heating & Air Conditioning system as well. A tune-up appointment helps to prevent the breakdown of your Heating & Air Conditioning system. This way you will not have to spend more money on repairs. It is only a one-time low-cost price. So make sure that your Heating & Air Conditioning system stays up & running just like my lipstick all day long & get a tuneup to help your Heating & Air Conditioning system.
