Final HVAC Set up Breakdown and Finest Practices

Analysis signifies that 70-90% of AC/warmth pump/furnace methods in houses are incorrectly put in and are prone to efficiency points.

Let that quantity sink in.

If you happen to’re fascinated about spending hundreds of {dollars} on a brand new system, and also you’re uncertain about learn how to spend that cash correctly, this text is for you. A very powerful day within the lifetime of any HVAC unit is the day of set up. A sloppy job leads to extra repairs, and presumably a shorter lifespan for the tools.

At Fireplace & Ice, we have now been requested hundreds of questions concerning the set up course of over time. We’ve compiled a couple of solutions that we hope will clear up some confusion.

What occurs throughout the set up course of? And the way is Fireplace & Ice’s set up completely different from anybody else’s in Columbus, Ohio, and the encompassing Central Ohio space?

There are two issues that must be on each HVAC contractor’s thoughts throughout the day: What’s in one of the best curiosity of the client? Are they happy all through the entire day? And second, is the machine working the way in which we stated it was going to?

How Lengthy Will the Set up Take?

Set up of a full system is a full-day course of. The day begins between 8:00 and 9:00 a.m. and might final till 6:00 p.m. — typically longer. The elimination of the present system can take 1 to three hours, and the set up of recent tools can vary between 4 and seven hours.

Any modifications to the prevailing ductwork, fuel strains, and electrical wiring can take longer for the system to be put in.

If there’s a whole lot of ductwork concerned, it’d flip right into a two-day job.

Earlier than Set up Day

With the set up of any indoor or out of doors unit, we pull the required permits, and never everybody does.

These are a number of the widespread causes your contractor could not pull permits:

• They aren’t licensed. Unlicensed contractors can’t pull permits.
• Pulling permits prices money and time. Simply as some contractors don’t carry out Handbook J Load Calculations, some don’t pull permits.
• They’re afraid of the inspection. Permits result in inspections. Some contractors are afraid to face a third-party inspector’s scrutiny.

Set up Day

We’ll present you photos of the installers who’re coming exhibiting up so when somebody exhibits up at your home, you’ll acknowledge them. We do this so that you’re not confronted with whole strangers.

On the day of set up, our professionally skilled crew will name you on the way in which to your own home to verify the appointment. If we’re putting in a full system, we ship two folks, one inside and one exterior.

And they’re going to arrive in an precise Fireplace & Ice truck, which isn’t widespread. I’ve had folks inform me that they informed the installers, “Go away,” as a result of the corporate’s title on the truck wasn’t the identical because the HVAC contractor they’ve contracted with.

Our installers put on the identical uniform as our salespeople. They are going to be carrying a masks, with shoe covers to guard your flooring. We’ll use drop cloths, and they are going to be clear. We clear these drop cloths every day, and we’re not speaking about shaking them into the wind. We wash them again at our residence workplace. We’re most likely the one HVAC firm in Columbus that has a washer and dryer.

We go over the job with you earlier than we begin. It looks as if a simple factor to do, however most corporations simply present up and begin working. The lead installer will take the time once they get there to assessment the job, inform the house owner what’s about to occur, so there’s no miscommunication.

That’s what we do exactly to prep for a job. It’s a course of, and it takes time, and it’s within the buyer’s finest curiosity.

Subsequent, they may correctly take away and eliminate any present tools. Subsequent would be the set up of the brand new tools.

We might all the time have a brand new out of doors pad for the AC/warmth pump. The one time once we wouldn’t do it’s if somebody poured their very own concrete pad. Normally, we put down gravel so the pad is degree, as a result of it does look nicer when it’s degree. We even have sensible causes for making it degree. There’s oil in that compressor. You don’t need oil solely on one aspect, and refrigerant gained’t circulate as effectively in a tilted unit.

We now have somebody on standby within the workplace in case there’s an issue that the individual within the subject can’t resolve.

Disposing of Refrigerant

In the course of the set up, what we’ll be doing in a different way is following EPA rules for disposing of refrigerant. We don’t lower corners.

Your present air conditioner incorporates a refrigerant that must be eliminated earlier than a brand new one might be put in. In line with EPA requirements, it’s illegal to brazenly vent this refrigerant into the ambiance.

A tool generally known as a restoration machine have to be used, together with a restoration tank, to securely and legally take away the refrigerant within the present central air conditioner system. That is the one course of that permits for the protected elimination and correct dealing with of the refrigerant.

There’s refrigerant in that previous system, and there’s an EPA regulation that you simply vacuum it down, to tug that R-22 out into a correct EPA tank. That is as a substitute of one thing referred to as bleeding or venting, which is the place you poke a gap within the refrigerant line and let it leak out, which is towards the regulation.

Brazing

After the road set is fitted to the service valves, they have to be brazed in. Brazing, a type of welding, is a course of utilizing two gases (oxygen and acetylene) and a filler rod manufactured from an alloy steel and silver to hitch the copper line set and repair valves. The valves are heated to a minimal of 1200 levels Fahrenheit, or till the filler rod will circulate to weld the connection.

If this course of is accomplished correctly, the copper line set, the filler rod, and the service valve are all melted collectively for a good, leak-free connection.

We braze with nitrogen, which sounds easy, however most corporations don’t do it. Nitrogen-based brazing is used throughout set up to stop contaminants from getting into your HVAC system.

Potential Problems within the Set up Course of

Sometimes an set up throws a curveball at us. The thermostat’s wiring might be a problem, and if the wires from the thermostat aren’t correctly linked to the furnace, we have now an issue.

{The electrical} panel may very well be unhealthy. We’re not electricians. Plumbing points can pop up. We ask if there’s ever an issue with drains. Typically we have now to interrupt via drywall for ductwork. That’s a complication.

Many of the unexpected points are client-based. Householders determine they need one thing moved, they usually suppose it’s no large deal. It’s a large deal in our world. Relocating HVAC tools is sophisticated and might be expensive.

A complication may come up from a miscommunication from our aspect. We current a whole lot of completely different choices once we’re sitting down with owners. Though we agreed on one, the consumer could have one other concept of what we agreed on.

Commissioning Course of

Our installers are required to fee (check) the HVAC tools earlier than they go away.

The startup and commissioning course of is finished after the system is totally put in and able to function. Commissioning can take anyplace from a half-hour to an hour and a half.  We use digital gauges as a result of they’re extra correct. Most set up technicians don’t have them, as a result of they’re 1099, they must pay for them themselves.

Once we’re commissioning and we uncover an issue, our techs don’t simply write down the quantity and transfer on. We now have to determine why there’s an issue. Commissioning is the fitting factor to do. Different HVAC corporations could declare to do that, however widespread observe suggests in any other case.

A superb installer will verify the thermostat operation, system sequence of operation, and a number of different areas. Whereas the system is working, the next information is necessary to gather to make sure correct operation inside producers’ specs:

• Suction and liquid line strain
• Suction and liquid line temperature
• Superheat
• Subcooling
• Out of doors ambient dry bulb temperature
• Indoor ambient dry bulb temperature
• Indoor moist bulb temperature
• Return air temperature
• Provide air temperature
• Static strain from return aspect, supply-side, and whole static readings
• Temperature drop calculated
• Excessive voltage present studying
• Amperage on the blower motor, out of doors fan motor, and compressor
• Low voltage present studying
• Line set size
• Quantity of refrigerant, if any, added to the system
• Distance above or beneath the out of doors unit in relation to the indoor coil
• Blower pace faucet/CFM recorded

That is the essential listing of the right information that must be recognized and recorded. That is the one technique to know for positive how the system is working and whether it is inside manufacturing specs. If any of those don’t fall inside producer specs, your system might not be warrantied by the producer.

As soon as the tools is commissioned, the installers will assessment with you all the pieces that was carried out throughout set up and go over any questions you’ll have. They are going to stroll you thru the place the filter is and learn how to change it. If a brand new thermostat has been put in, they’ll present you the way it works.

Closing High quality Inspection (FQI)

Per week or two after set up, a Fireplace & Ice consultant will return to your own home to make sure all the pieces is working easily, to be sure you perceive your thermostat and luxury choices, and to examine the standard of the set up. If something is amiss, it’s reported to our coaching and administration workers and is used to tell adjustments to our set up practices and coaching.

We’re proud to be the one contractor within the space who will return for this go to to look you within the eye to be sure you’re happy with the job that was carried out.

We expect that FQI is a vital a part of the set up course of.

We take photos earlier than, typically throughout, and after. That helps us to ensure we did it proper. If there’s an error, we are able to take a look at the images and determine earlier than we get there what the issue is perhaps. It additionally helps with guarantee points. We will present that we did issues proper if one thing goes improper and we get accused of a poor set up.

Vital Steps That Are Typically Skipped

The explanation different corporations don’t do a number of the steps we’ve talked about is that it takes extra time or it prices an excessive amount of cash. Doing issues proper takes longer. Doing issues proper prices cash.

To most installers, time is all the pieces. They don’t care in regards to the consumer. If there’s a course of they’ll lower, which means they’ll get out of there faster, they receives a commission faster. Possibly they’ll get carried out rapidly sufficient to get one other job. They receives a commission by the job, not by the hour.

Our HVAC contractors at Fireplace & Ice receives a commission by the hour. In addition they get a bonus for installations which can be trouble-free. That permits them the time to do issues proper. As a result of if it’s not carried out proper, it’s not value doing.

Your Subsequent Steps

I hope by now you’ve a greater understanding of what sometimes goes into putting in a brand new heating and cooling system.

One remaining thought:

The model of kit issues lower than the standard of the set up. It’s true {that a} lesser high quality piece of equipment is not going to final so long as a greater one, if the set up, upkeep, and utilization are the identical.

It’s like a Yugo versus a Cadillac. The Yugo, even when it’s correctly maintained, can have extra issues than the Cadillac, if it is also maintained. A greater-quality model of furnace can have extra consolation choices than an entry-level one, which is fixed-speed, single-stage, with a single-stage of heating or cooling. When you’ve got consolation considerations – resembling extreme dry air within the winter, or mugginess in the summertime – an affordable furnace or air conditioner can’t deal with these.

Any supplier can set up Trane or Provider in the event that they need to, as we do. However the set up would be the most important distinction in high quality. On your peace of thoughts, check out our contractor’s guidelines to see how corporations measure up:
