Q: How can we cool the room over our garage in the summer and warm it in the winter? No space heaters or window AC units, please! A: Richard Trethewey replies: Sounds like you need a mini-split heat pump, which provides cooling and heating fairly unobtrusively without using ducts. It pushes refrigerant from an outdoor condenser directly to a wall-mounted air handler that blows hot or cold air into the room. Because there are no ducts to retrofit, the system is simple for a pro to install. And it provides excellent dehumidification, quiet operation, and great efficiency.

Heat pumps, hands down, allow your home to be far more comfortable. You can learn more about their program here. If the benefits of heat pump ownership versus an oil furnace interest you then take 30 minutes o meet with one of our Home Energy Specialists.

Locate the outdoor unit in the desired location with a good route for the refrigerant lines, mark the mounting bolt locations, and drill the mounting holes. Fasten the unit in position. If using wall brackets, make sure they are securely fastened to the wall - with wood-frame construction, secure them to studs with lag bolts.

In the picture, the horizontal bar is fastened to studs on 24" centres while the unit feet and brackets are on 21" centres. Connect the inter-unit cables to the outdoor unit. Route the cables with a downward loop so that water does not track down the cable into the unit.

Cut the refrigerant lines to length, re-fit any insulation if required, thread the flare nuts onto the end of the pipe and flare the ends. Ensure there is enough slack to allow connection to the unit without sharp bends, and preferably enough to cut and re-flare the end if the first attempt is not satisfactory. Connect the lines.

Connect the V power lines, ensuring that the unit is properly grounded. The Aura is pre-charged with refrigerant, though if refrigerant lines more than 7. The refrigerant lines and indoor unit coils must be pumped down and allowed to outgas any moisture.

Pump the lines down for at least 20 minutes, ideally longer, and make sure the pressure does not rise significantly when the pump valve is closed at the end of this period. Open the packed valves to allow refrigerant into the lines, disconnect the coupler closing the Schrader valveand leak-test all the joints including those on the indoor units.

Installing a Mini-Split Heat Pump: IntroductionHeat pumps are one of the most efficient ways to heat a house - since they pump heat, rather than create it, they. Heat pump installation. Much like an air conditioner, a heat pump installs outside your home and then connects to either your existing furnace, air handler or. Heat pump installation is no easy task, but some homeowners are up for the challenge. Here are the steps and tools needed to install a heat.

Close up the indoor units, connect the power, turn the system on and test it. I'm not trying to be disrespectful but there is a lot wrong with the above Instructable. In the HVAC world you never come across flare fittings for a reason, they leak! Also you should never use a vacuum pump as a indicator of a leak. At the most you are putting 15psi pressure on the outside pulling in. Properly done you purge the lineset with dry Nitrogen to psi and wait 30 minutes and check for a difference.

Then you pull a vacuum but not just any vacuum you want a vacuum to microns or lower! When your pulling a vacuum your extracting all the non-condensables out like air and water. If there is water in the lineset and pull a vacuum without a micron gauge you have no idea how good of a vacuum your pulling and running a risk of shortening the life of your compressor. Or hooking up a micron gauge to your vacuum pump directly to see if it can even pull or lower microns.

When you reduce pressure you lower the boiling point of water from degrees f to 70 degrees or lower causing water to boil at room temperature and extracting all the water. Reply 4 years ago on Step 5. As you can guess this is my first attempt at a heatpump system, and I'd probably do things differently a second time. There was a local rebate program, my ceiling heating was broken, so I bought the cheapest system I could find on the basis that if it worked I'd get the cost back fairly rapidly in lower heating bills, and anyway how hard could it be.

The AURA series do indeed use flare fittings. Maybe more expensive or better engineered models don't. Some of what I wrote is more-or-less straight out of their installation manual. The unit is probably manufactured in China for a US company, but the instructions were written in the US and translated to metric for the Canadian market, which is where I bought it.

So I was basically following the manufacturers instructions rather than using a textbook. I was using a Tri Vac roughing pump as used for physics experiments, with an Pirani pressure gauge.

I figured that was probably good enough - no need to go to a turbo pump and get 10 microns or whatever, seeing as the installation manual shows a bourdon gauge and the only point I could see in pumping down was to remove any moisture from the system as you say.

As for heat pump installation prices I'll defer to my favorite answer: it depends. But since it depends never seems to work for my daughter - or.

I hope I didn't sound critical or harsh about my opinions. Most mini-splits have flare fittings but I prefer not to use them.

Flares are great, they are easy to disconnect. You don't really need a micron gauge but without one your not sure if your still drawing out moisture. Actually I lied in the US your required to pull a vacuum of microns or less according to the EPA so basically implying you need something to measure microns.

After the hose is checked to make sure it drains freely, the end of the hole sleeve is sealed with silicone to prevent water infiltration. Then the channel is capped, as shown.

A gauge manifold and a vacuum pump are hooked up to the refrigerant lines to detect leaks and dry the lines as refrigerant is pumped into them. The last step is to put the cover on the air handler, as shown.
