We save you money on installation costs.

Our patented pre-charged line sets allow you to install a heat pump yourself with no special tools, equipment or knowledge.  Doing it yourself or appointing a local handyman, will cost a fraction (up to 60% less) of what an HVAC engineer will charge.

We save you money on energy costs.

Next-generation air sourced heat pumps harvest outside warmth at -30°C and save energy year-round. It is for this reason that they’re 300-400% efficient. For every dollar they use to run, they can provide three to four dollars worth of energy, saving you up to 70% on your energy costs.

MrCool Universal Series can heat effectively below freezing. It can even heat effectively below zero and keep heating effectively down into negative double digits. It can keep a 1500 sf house at 70 degrees in -20 and below – you can view the tech specs here.

Our DIY systems are ultra-quiet because they were ‘specifically designed’ for strata properties and condos and are inaudible from anywhere within the building.

The maximum rated sound level for the outside compressor(s):

Single Zones (dBA)
12K (45)
18K (58)
24K (60)
36K (64)

Multi Zones (dBA)
27K (63)
36K (64)

It’s rare to run at maximum because once the internal set point has been reached, the compressor will shut down. We can say with certainty that when the compressor only needs to maintain equilibrium, the noise level is considerably less – akin to a quiet whisper. 

So we could say the rated range is from a quiet whisper (30 dBA) to normal conversation at 3 feet (64 dBA).

Homes are generally a set distance apart from one another. If we say 24 feet for easy math – we can apply the inverse square law as follows:

18K = dBA (58 – 18) = 40 dBA (sound of a quiet refrigerator)

27K = dBA (63 – 18) = 45 dBA (faint rainfall)

This is the noise level outside “standing outside”. If an occupant was standing within the building – it would be significantly less because you’d need to account for double glazing and building insulation. This would reduce the sound level by a further 30 – 50% – making them inaudible to anyone inside the building.

This video shows one of our compressors running on maximum – this unit is the largest we sell (36K) – it is self-evident that I can easily talk over the top of it.

If you purchase an alternative system and do not have it installed by a licensed HVAC professional you may void the warranty. Some systems appear to be DIY products but when you check the small print – you’ll find that they need a licenced HVAC contractor to prevent voiding the warranty – please see below.

Proper installation – Limited warranty applies only to systems that are installed by a state-certified or licensed HVAC contractor[1], under applicable local and state law in accordance with all applicable building codes and permits, Senville installation and operation instructions and good trade practices. The Company reserves the right to request proof of proper installation before enforcing this warranty.

Comparing any non-DIY product that voids the warranty unless professionally installed by a certified or licensed HVAC contractor – is not the same as our tier 1 product that comes with a full DIY warranty, a high level of technical support and parts availability. Warranties and product quality protect your investment and are an important consideration when comparing products.

Please watch this video here for how the Mr Cool tech support process works.

In the first instance – please contact them on 270-366-0457 and follow their tech support procedure.

It’s important to note that they operate on a recorded call system. You leave your name & telephone number – they will call you back in priority sequence. They are based in Kentucky so will be operating on central time – for this reason, it is important to provide your cell phone number.  We do not provide the manufacturer’s technical support or process warranty claims. Once they have you in their system they do an excellent job. In almost all cases they manage to rectify technical issues with you over the phone. It requires a little patience and confidence that they will get to you in sequence.

Displacement heating is where a heat pump provides most of the home’s heating and cooling – year-round.
It is equivalent to boiling warm water – very little energy is needed to bring it to a boil. Similarly, with your home’s heating/cooling – very little energy is needed to heat/cool areas where air handlers are not installed. If the room’s temperature is 18C and the occupant turns the baseboard up to 21C – very little energy is consumed before the baseboard thermostat shuts off. This is due to the latent effect of the heat pump. The additional energy [when needed] using a displacement baseboard approach is minimal.

Many cold-weather heat pumps -15C use resistive heat (same efficiency ratio as a baseboard heater 1KW:1KW) to operate below -5C. This is no different to operating a baseboard in the house. The fact that your heat pump provides 80%+ of your home’s heating/cooling is a huge energy saving. Sometimes it’s not worth spending twice the amount for a 20% gain.

Here’s what we suggest you do:

1. Reconsider if you can actually do it yourself – perhaps you could enlist the help of a friend, neighbour or a family member?
2. Try looking online or asking if anyone in your local community knows a good handyman?
3. Ask your local electrician if he can install the system for you. Remind him that he’ll be doing the electrical work and it’s not that difficult for him/her to drill a 3.5 inch hole. This is a great opportunity for them to earn an installation fee on top of any electrical work.
4. Consider calling up a general contractor and asking them – people like this know many tradespeople that may be able to help.
5.  Email these people the links below to show them just how easy it is to install one of these systems.

Our systems are 60% less cost to install than an HVAC company will charge because our pre-charged line-sets remove the expensive HVAC labour cost. The only skill needed to install one of these systems is the ability to drill a hole. If you cannot or do not want to do this – then you may need to consider paying two or three times the costs for an HVAC company to fit a non-DIY system.

The air handlers are connected to the condenser by a low voltage [extendable] communication cable and follow the same route as the line sets. The communication wire is extended by cutting it and adding the new line – it is re-joined using standard electrical crimps – see here.

You can either do the electrical work yourself and ask a qualified electrician to check/test and sign it off or ask them to do all the work.

Note: If you’re applying for a rebate you’ll need an electrical permit – home wiring with the district or anyone but a qualified electrician signing it off – is not valid.

Installation of the product must comply with all applicable codes and regulations. The service of a certified and trained electrical technician may be required for the installation process. 

In many cases, a professional electrician may be willing to sign off on your own electrical work, provided that s/he feels comfortable with your experience and skills. They will need to check/test your wiring to ensure it meets building code and electrical safety standards. You will need the electrical installation permit in order to claim the rebate. If you don’t want to do this – that’s fine, but you are unlikely to qualify for the rebate.

Please note: electrical homeowner permits are not acceptable for this type of installation because you have not installed using a licensed professional e.g. electrician.

What sizes do they come in – what if I need more than 25′?

Line sets come in standard 25′ lengths and are joined together using a coupler. The coupler comes with an additional 25′ – 50′ length of communication wire. This original wire is cut and extended to the length desired using standard electrical crimps. We also have non-standard 16′ line set lengths available for purchase.

What’s the longest line-set length(s)?

The longest single length is 115 ft – this is made up of a combination of 16′ or 25′ line-set sections with the use of one or more couplers.
The maximum total [combined] length is 262 ft.
The maximum vertical height [not length] between the condenser and any air handler is 50 ft.

If we have to special order an item – shipping is typically 2 – 4 weeks and we aim to carry most items in stock.

When it comes to ordering a multi-zone system – you’ll need to order it as a complete kit. You cannot order in bits and pieces because they are not sold as individual products. It would not make sense to order a smaller kit e.g. lower total number of air handlers because the shipping costs of the additional items would work out more expensive. Also, there are technical constraints of fitting a min 50% BTUs of the compressor e.g. 36k compressor needs min no of air handlers [9K + 9K].

Configure Your Mr Cool DIY System Bundle

Please give us (1) the Bundled System Model Number & (2) the Components in Bundle list.

This will give us the necessary information we need to provide an accurate quote for you.

• The total number of air handlers (zones).
• The BTU size of each inside air handler.
• The BTU size of the outside condenser (27K/36K).
• The line-set lengths from the condenser to each air handler.
  Note: these come in 25′ sections and connect together to a maximum of 116′ per run.

If you have any questions please contact us for assistance.

The manufacturer’s slowly moving from 3rd to 4th generation so is running stock levels down.
We anticipate the 4th generation being available within six months and are taking pre-orders (no prices as yet).

If you don’t want to wait and would like to order now – you’ll need to replace the items in red with the items in blue.

9K Air Handler with a 12K Air Handler
27K Condenser with a 36K Condenser

Note: a 12K air handler will behave in the same way as a 9K because it has a DC inverter that lowers the input according to demand.

If you have yet to order you have two choices:
1. Click HERE to configure your system bundle – please email us:
– Your Bundled System Model Number
– Components in Bundle
2. Wait for the next generation ~ 6 months.

If you have already ordered you have two choices.
1. Click HERE to reconfigure your system bundle – please email us:
– Your Bundled System Model Number
– Components in Bundle
2. Request a full refund and wait for the next generation ~ 6 months.

Note: although the next generation is due to arrive at some point later this year – it will be more expensive. So it is our recommendation to see if you can make (3rd Gen work for you). There will be no difference in terms of support, warranty or parts availability between generations.

Current Lead Times:
Single-Zone Systems: 10 to 14 days.
Multi-Zone & Central Systems: 4 to 6 weeks

Multi-Zone systems start from $4500.00 for a dual zone up to $6700 for a four zone system.

Universal central systems start from around $6340.00 for a 2/3 ton system up to $7500.00 for a 4/5 ton system.

Delivery included.

For example, if you live in BC you could get up to $11,000 for switching to an electric heat pump from a fossil fuel heating source. This includes a $3,000 rebate from BC Hydro, which is in addition to CleanBC’s existing $3,000 rebate. Eligible applicants can receive a combined rebate of up to $6,000 from BC Hydro and CleanBC in one application while funding lasts. 

You may also be eligible for up to $5,000 in additional rebates from the federal government’s Canada Greener Homes Grant. This is a separate program with its own eligibility criteria and application process, which requires registration and a home evaluation before making any upgrades. 

The great news is you can find our MR COOL DIY Heat pumps on the rebate-eligible heat pump list provided by BC Hydro so you’re already one step closer to an efficient, rebate ready heat pump system.

Note: The must be mounted no less than 5.9″ from the ceiling and are not suitable for wall mounting.
Note: The DIY systems come with wall-mounted and not cassette type air handlers.

We do not recommend ordering partial kits as full kits are discounted. These items are drop shipped from our warehouse, so it is more cost-effective to send everything together on one or two pallets. You don’t have to install the additional air handlers immediately as long as you fit  50% or more of the condenser’s capacity e.g. 36K condenser = air handlers 9K + 9K.

A 12K air handler can act as a 9K air handler and not affect performance. This is because the system contains a DC inverter that allows the system to provide the exact amount of energy required for a zone. Unlike old-fashioned systems that used to shut off, these modern systems adjust their output rates accordingly.

There is not much difference in cost – and you are getting a slightly larger capacity.
