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.

Note: It’s illegal in Canada for any HVAC company to refuse to service a competitor’s products. If they do they will have committed an act of “conspiracy” and will be in breach of The Competition Act. This carries a minimum prison sentence of 14 years for anti-competitive behaviour.

As Canada’s largest supplier of DIY Heat Pumps, we service the whole of the country coast to coast.

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.

Displacement heating is where a single zone 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′?

Single Zone systems come with a standard 25′ length – this is not exchangeable as it comes pre-packaged – these can be extended by purchasing additional 16′ | 25′ | 35′ | 50′ sections & coupler kits.

Note: The coupler kit – includes an additional length of communication wire to extend the line between the air handler to the condenser’s electrical panel.

Multi-Zone systems are flexible and come with a choice of 16′ | 25′ | 35′ | 50′ line set lengths – so using a combination of these you’ll be able to get close to the total length you’ll need.

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

Condenser less than or equal to  27K BTU’s
The longest single length is 75 ft.
The maximum total [combined] length is 197 ft.
The maximum vertical height [not length] between the condenser and any air handler is 49 ft.
The maximum vertical height [not length] between the lowest and highest air handler is 33 ft.

Condenser greater than or equal to 36K BTU’s
The longest single length is 75 ft.
The maximum total [combined] length is 262 ft.
The maximum vertical height [not length] between the condenser and any air handler is 49 ft.
The maximum vertical height [not length] between the lowest and highest air handler is 33 ft.

If you live in Vancouver, the lower mainland or Vancouver Island we offer next day shipping on single zone systems or free collection.

Ontario and the rest of Canada – single zones ship within 7 – 10 days or free collection at your nearest collection point – see here for your nearest location.

Multi Zone and Universal (central) systems:

These are shipped directly from our main warehouse and usually take 3 – 6 weeks.

Please note: lead times do change so please ask at the time of order.

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].

To receive a multi-zone quote – please email us the following:
(1) How many zones you need?
(2) The size in sq. ft of each zone?
(3) The approximate pre-charged line-set length for each zone (outside condenser to inside air hander).

*Limited lifetime condenser replacement warranty – subject to product & manufacturer’s terms.

– 60% less expensive to install compared to HVAC prices.
– We offer the best warranty in the industry – a *lifetime condenser warranty.
– The rebates often go directly to the HVAC company, not the consumer. Many companies add the rebate to the bill – see the real-life example below.
A recent customer of ours was quoted $15,000.00 to install a 24,000 BTU single zone system – he purchased and installed a DIY system from us for $3,000.00  – he saved $12000.00 without needing a rebate.  

Q. Is it worth spending an extra $12,000.00 to obtain a $1000.00 rebate? 

We offer you a better value product that costs a lot less to install, it also comes with the best warranty in the industry.

* Subject to manufacturer’s terms.
** Rebates are not currently available on DIY products but this may change again in the near future.

All customers had been successfully receiving rebates for our products up until the middle of June 2022 – it would seem that the changes coming into effect on July 1st 2022 were implemented early by BC Hydro. We agree that this was unexpected, but there’s nothing we can do, as this is something out of our control.  DIY heat pump products do attract various rebates in the US – so please let BC Hydro know how you feel, as their tool HERE continues to list our DIY products as eligible for rebates.

Rebates were subject to the “relevant trade” – our systems come with pre-charged line sets so they don’t require an HVAC technician to vacuum the lines and charge them with refrigerant. Before the recent changes, a qualified electrician was the only relevant trade for this type of heat pump installation.

Rebates are never guaranteed and are subject to change depending on funding availability and criteria.

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.
