A/C within the Winter?! Off-Season Set up and Operation of HVAC Cooling Tools

When the climate turns chilly, every part you see from HVAC firms focuses on heating. We’re no exception right here at Hearth & Ice. It is because our clients change into extra all for new furnace programs, or getting service on their current heating programs.

Nonetheless, we nonetheless set up air conditioners within the fall, winter, and early spring months. And infrequently, we speak to individuals who have to run their A/C throughout these months.

So this text goes to speak by way of a handful of subjects associated to wintertime cooling, together with:

1. What concerns are there when putting in an air conditioner within the winter?
2. When would possibly somebody have to run their A/C within the winter?
3. What must you do to guard your gear within the coldest winter months?
4. Is there a “proper” time to put in or schedule upkeep for HVAC gear as you head into the coldest time of 12 months?

The solutions to a few of these questions will depend upon issues just like the state of your system, your funds for a brand new HVAC mission, and the local weather you reside in. Nonetheless, we are able to present a whole lot of normal steering that ought to assist any home-owner of their subsequent massive choice.

The Vacation Get together – Cooling a House When It’s Chilly

Have you ever ever been to a big vacation celebration within the winter, one with dozens of individuals in a house? You’re sporting a sweater and lengthy pants, and ultimately you end up sweating resulting from all of the individuals within the enclosed house. Opening some home windows would possibly assist, however it can additionally simply create drafty pockets of chilly air, quite than cooling evenly.

The query is: are you able to run the air con on this situation?

For many programs, the reply shall be no, however an important query to ask is about temperature. What’s the skin temperature? Customary air conditioners can typically cool all the way down to 55-60 levels. But when it’s decrease than that, you’re working a number of dangers by working the cooling unit.

Technically there are kits that may be connected to some programs that may assist with this. These are often called low ambient kits. They aren’t frequent in residential properties. Extra typically, you’ll see them put in with industrial air con models. Nonetheless, with these kits, some models can cool when it’s as little as 20 levels exterior.

Some fashionable gear is starting to push the envelope on that 55-60 diploma rule I discussed above. We just lately reviewed the XV20i variable-speed air conditioner, together with the way it can cool at temperatures beneath 50 levels.

The rationale it may go beneath 50 levels is due to its superior moisture management. The worry with cooling in low temperatures is that your outside unit develops frost on it. That frost can result in ice bubbles that may ultimately shut down a system or injury its inner elements. The XV20i, and different models of comparable sophistication, are in a position to higher keep decrease ranges of moisture buildup in an effort to mitigate this threat.

That mentioned, that is nonetheless removed from the norm, so one of the best normal recommendation is to keep away from utilizing your A/C unit when it’s colder than 55 levels exterior.

What About Warmth Pumps?

The identical cooling limitations apply to most warmth pumps. Nonetheless, your warmth pump may also be heating within the winter.

Warmth pumps used to close off when temperatures approached freezing, and your private home’s warmth would come solely from the furnace at that time. Trendy warmth pumps are starting to enhance, although. The perfect ones will proceed to offer environment friendly warmth all the way down to as little as 15-20 levels Fahrenheit and have a defrost cycle to stop them from increase ice.

There are exceptions to this. Whereas a conventional all-electric system will characteristic a mixture of warmth pump and furnace warmth at decrease temperatures, the 2 can’t function on the identical time when a warmth pump is paired with a fossil gas furnace (pure fuel, oil, propane). These situations are uncommon, however do happen in some properties which have a hybrid electrical/fuel HVAC system.

Putting in an A/C within the Winter

Can an air conditioner be put in within the winter? In a phrase, sure.

There’s nothing stopping an HVAC contractor from doing an important job on a brand new A/C set up through the colder months of the 12 months. The one minor step that shall be lacking is definitely working the A/C if the temperature is simply too chilly. Nonetheless, all of the steps wanted to check and set up an air conditioner are doable at any time of 12 months.

Specifically, correct pressures on the refrigerant in any respect phases of the cooling cycle are vital to keep up. An air conditioner comes from the manufacturing unit with a certain quantity of refrigerant in it. This quantity relies on a sure size of refrigerant tubing working from inside your private home to exterior and again. If the tubing size is completely different (which is able to depend upon your private home), the refrigerant quantity might should be altered.

With out having the ability to run the unit at colder temperatures, the best way you guarantee that is by exactly measuring the quantity of refrigerant added (which shall be explicit to that make and mannequin).

It’s doable to “eyeball” this course of, however that opens your system as much as a ton of threat. An excellent contractor will use an digital scale to measure the quantity, to make sure the system is put in to fulfill state and native codes.

In any other case, we virtually by no means say no to some scorching chocolate when it’s supplied on a chilly day for outside set up. However the set up itself is not any downside, even in freezing climate.

Freezing Temperatures & HVAC Tools

No matter when you may have your system put in, if you happen to dwell in an space with harsh winters, you’re going to should navigate the chilly climate. However what does that imply in your HVAC gear?

The very first thing to bear in mind is that the weather can positively have an effect in your gear. The second factor to bear in mind, although, is that with correct preparation, you’re going to be superb.

Over time, moisture in and round your outside unit (from snow, rain, and many others.) might begin to rust the outward-facing elements. That is superb. Many programs include a rust-resistant coating, however even this can ultimately give solution to rust. The excellent news is, that is virtually all the time beauty and gained’t have an effect on the operation of your system. With a well-coated unit, this could additionally take 10+ years to start to see in any respect.

Some fear about snow accumulation. Once more, you’re in all probability okay right here, until it’s a warmth pump that shall be working extra recurrently within the winter along with cooling in the summertime. In these instances, eradicating massive piles from across the unit is most secure.

A associated worry is icicles, and right here we’ve truly seen some injury. Massive icicles can type on the perimeters of your own home, and in the event that they fall onto (or into) your outside A/C, injury can happen. The answer here’s a cowl. Some, like many Trane models, include a Weatherguard high that may shield in opposition to this. Different instances, you could merely have to position a wood or plastic board over the unit, then take away it within the spring earlier than utilizing it.

Most vital is to have yearly upkeep, which we’ll speak extra about within the subsequent part.

Heck, it’d simply be that your filter is hopelessly clogged. One thing so simple as this could have an effect on the complete heating and cooling system.

In any other case, chilly climate doesn’t change the overall advice that you simply’ll get from any respected contractor: you need to have your heating gear serviced within the fall earlier than use, and the cooling gear serviced within the spring earlier than use. Some householders will mix these two right into a single upkeep go to per 12 months, and that is superb too. The one poor alternative is to not schedule it in any respect.

Discovering “The Proper Time” to Set up

One of many myths that we’re blissful to bust is that there’s a “greatest” time to put in a system. The perfect time is the one which’s best for you, your private home and household.

Nonetheless, there are just a few objects that will decide when one of the best time is for you:

1. HVAC prices don’t go down. No matter it is going to be this 12 months, it is going to be at the least that a lot subsequent 12 months.
2. Low season installations (like air conditioners in winter) aren’t higher or worse mechanically, however you’ll profit from the additional consideration of getting it achieved throughout downtimes for a lot of HVAC firms. Need next-day set up? You in all probability gained’t get it in
