But a reputable contractor is always a good idea
Spring has finally hit the Lower Mainland, and the trees are in bloom all over Langley, Surrey and everywhere in Vancouver. Our local farms are readying the fields for their strawberry and veggies. And homeowners like you are beginning to remember the sizzling heat of the last two summers and thinking now’s a great time to get an air conditioner. Of course, it’s tempting to run to your local big box store, buy an air conditioner and head home to install it on your own, in the hope that you’ll be saving money by doing it yourself. Or you might think that hiring a local handyman “who can do it all” is a good money-saving decision. However, when it comes to your home comfort, it’s important to know that many contractors that don’t specialize in home comfort system installations do not know how to size an air conditioner or furnace properly. Some people still think that “bigger is better.”
In reality, it is essential to size your equipment correctly. With air conditioners — an undersized unit will not keep up with the demand on hotter days, and an oversized unit will not sufficiently dehumidify the home, leaving it feeling uncomfortable, even though the temperature is at an appropriate level. Furnaces also have issues when not appropriately sized, such as “short-cycling.”
Improper installation can pose serious risks to you, your family, your business or home. And that’s one of the many reasons it’s essential to hire a professional heating installation service.
Credible contractors know the importance of specific processes that “low bidders” often omit.
Purging with nitrogen while brazing the refrigerant lines together is an important step. Refer to the image in this article, showing the difference between a braze with and without nitrogen. The black buildup on the inside of the pipes gets scrubbed off by the refrigerant flowing through the system and clogs up small orifices and metering devices in the system. Displacing the oxygen by flowing nitrogen through the pipes while brazing prevents this from happening.
Another thing that credible contractors do is to “pull a vacuum” after all the connections have been completed, which involves hooking a specialized pump up to the system and running it until an acceptable vacuum pressure has been attained. This indicates that the system has no leaks, and also removes any potentially damaging moisture from the system.
DIAL THE SYSTEM IN ON STARTUP
After furnaces and air conditioners are installed, a full “startup procedure” should be performed on them – again, this is something that is often skipped.
While a low price upfront sounds excellent, it will end up costing you more in the long run if the system is not installed correctly. I like the saying “If you think it’s expensive to hire a professional to do the job, wait until you hire an amateur!”
Proper installation can guarantee better performance and lower running costs. If your heater is installed by a professional, you can expect it to work optimally to achieve desired temperatures.
