Equipment Selection & Installation

1. How do I choose the right heating or cooling solution?

 

Key considerations include the size of the area you wish to heat or cool, the local climate, the number of windows in the area, insulation in the walls and possible location options.

Correctly determining the size of equipment for your space is critical and directly relates to how much energy or heat the unit can produce.

An undersized unit will be ineffective in bringing a room to the desired temperature, while an oversized unit will turn off and on frequently, causing wear and tear.

3. Where should I place my heat pump? Can heat pumps be recessed into the wall?

 

For air to freely circulate, there should be no obstruction around the unit. The best location for a reverse cycle heat pump is near ceiling level. The best location for a heating-only heat pump is at floor level.

Modern heat pumps are generally unobtrusive in style and size. Hi-walls are mounted close to the ceiling and some floor consoles can be recessed into walls. Cassettes and ducted split systems can be hidden in the ceiling.

 

4. How long will my heat pump last?

 

Good quality equipment, installed by qualified contractors, can have a life span of 10 to 15 years. Poor maintenance and environmental factors can cause premature failure. Regular inspection and maintenance will allow your system to operate normally for as long as possible.

5. Are heat pumps noisy?

 

No. The leading brands on the market have very reasonable noise levels. You will find most of the noise you are hearing inside your house is the sound of the air being forced out of the internal grills, similar to a circulation fan. You can control how fast the internal fan runs and thus its’ noise levels, by using the remote control.

A loud heat pump is annoying, but it could signal a major problem that needs to be addressed before your unit tears up completely. When you need a quality heat pump repair company, contact HPAC Energy Centre for all of your maintenance needs. We provide routine maintenance and emergency servicing, so contact us today to have all of your heat pump needs taken care of. Our technicians are experts in the industry and can help keep your unit running efficiently for as long as possible.

 

6. Why do I need a condensate pump?

 

All air conditioners create condensation (i.e. - water) as a byproduct of cooling. The way they cool down your house is by reducing the interior humidity. Dehumidification creates water, and that water has got to go somewhere.

Ideally, you want that water going outside of your house. In a central air system or a ductless system, the condensation will build up in a drain pan. From the drain pan, the water is emptied outside the house via a condensate drain. In many cases, this is just a simple gravity drain.

A condensate pump is a relatively small, simple device. You install it with the air handler. When the condensate builds up, the condensate pump pumps it out. It uses mechanical force to remove the water, so you don't have to worry about water overflowing the drain pan.

So, if you want to put a ductless mini-split in a location where gravity-fed drainage would be an issue, get a condensate pump. It will keep the water moving out while you stay cool.

 

7. How long will my installation take?

 

A typical back-to-back installation of a single split system, without any complications, takes approximately four hours. Meanwhile, installation on an internal wall can take up to one day.

Times can vary from project to project, depending on the complexities of the building, pipe runs or electrical requirements.

8. How long is the warranty period on a heat pump?

 

Most brands offer 5 years warranty. The Daikin '5-Year Parts and Labour' warranty applies to all Daikin split, multi-split and ducted heat pumps professionally installed in domestic premises in New Zealand. Similar policy for Mitsubishi Electric, Panasonic. Haier, Gree, Fujitsu etc.

Check with our expert now on specific brand and policy.

 

 

9. What refrigerant is in my heat pump?

 

The earliest systems used chemicals that were either toxic or flammable, but modern heat pumps use safe blends referred to by the general name “Freon” (a trademark of DuPont). The main blends used today are R32 and R410A which has replaced an earlier blend, R22.

 

10. Can I add WIFI to my heatpump?

 

The Wi-Fi Interface is available on selected brands and products and can either be purchased as an optional upgrade when purchasing a new heat pump, or retrofitted to an existing model.

11. Can I upgrade cooling to ducted systems?

 

You may add cooling to your ducted system. Add-on Coolers utilise your existing heating ducts to circulate cool, crisp air throughout your entire house OR just selected zones. Because you already have ducts installed, you can get all the benefits of a complete ducted refrigerated system and save up to $2,000.

12. Will a heat pump ventilation help my condensation?

 

Heat pumps are amazing appliances! While a heat pump’s primary purpose is to heat or cool your room, some heat pumps do offer limited dehumidification using “DRY” mode. It is important to note that when the heat pump is operating in Dry Mode, the unit is not heating so it is recommended to only use the Dry mode for shorter periods of time and when heating is not being required.

A home ventilation system is different from a heat pump because rather than just heating and cooling, it is specifically designed to constantly keep your home well ventilated. Some heat pump systems do provide a dry mode function, but can’t be run in dry mode all the time.

To help our customers decide on tricky problems such as this, we have the most experienced HVAC experts that can assist you in finding a heat pump or ventilation system that is right for your home. Talk to HPAC now for a free in-home consultation.

 

13. Can I put a cover over the front of my outdoor unit to make it less visible?

 

The outdoor unit of a split system air conditioner requires adequate clearance in order to function correctly. Its performance depends upon efficient outdoor heat dispersal, so covering the unit will affect this.

Allowing at least 1 metre of clear space on each side of the air conditioner is a good rule of thumb to utilise.

If you would like to cover your outdoor unit, your HPAC Specialist can advise you on whether an ‘air deflector kit’ can be used for your particular system.

Consult with our HPAC experts and we will provide you the best options for your home!

 

14. Can I re-use the piping which is already installed for my old Air Conditioner?

 

In most cases, you cannot re-use piping and cable from existing air-conditioning units for any new units you are having installed as different systems use different piping and have their own specific electrical requirements.

There can be exceptions to this, depending on your individual situation. We need to do onsite inspection to see if we can do that.

Please speak to our HPAC Specialist for more information.

 

15. What if I don't have a roof space (attic) for ventilation?

 

Most ventilation systems rely on having a roof space to run the ducting to the various rooms. If you don't have a roof space your options are limited.

  • For suspended floors (ie not a concrete floor) you may be able to install ventilation ducts underfloor with floor vents.
  • There are also through-the-wall options on a room by room basis. The SmartVent option for this incorporates heat recovery efficiency.

 

16. What is a Positive Pressure Ventilation System?

 

The objective of a positive pressure system is to pressure fresh air into your home to push out the damp, stale air through gaps around doors, windows etc.

This system works effectively in older homes, but more airtight homes should consider a heat or energy recovery system that draws the stale air out as it introduces fresh air. This is also known as a balanced ventilation system. 

 

17. Can I install the heat pump myself?

Speaking of HPAC specialists, when you’re installing a heat pump it might be tempting to go down the DIY route, but this is one area where it’s best to leave it to the professionals. Heat pump installation requires both electrical and plumbing work, so it can quickly become complicated. And if the installation process is botched, you risk an inefficient heat pump – not the ideal situation.

Another upside to having professional help with heat pump installation and selection is that they’ll be able to ensure your home has the right type heat pump – and the right size – to suit your home and family’s needs. The brands we are partnered with also offers a five to six year warranty on the heat pumps we install, so that’s just another reason why it’s wise to use the experts!

 

 18. Do they need a drain?

Yes. The indoor unit on cooling will dehumidify and the resultant water needs to be led away. That is why they are typically mounted on an outside wall. If not, a condensate pump can be used to lift the water to the ceiling to be drained out. But sometimes condensate pumps can be heard when they operate. The outdoor unit when on heating will also produce water. The amount of water produced is similar to a dehumidifier in use.

 

19. Is a heat transfer system also a ventilation system?

While some ventilation systems are combined with heat transfer systems theses days, a heat transfer system on it’s own simply moves around air and heat that’s already in the home, blowing it through ducts or vents. It does not bring new air in and you need to have powerful heat source to make it worthwhile. A heat transfer system is great paired with a wood burner as they generate more heat than is needed for one room.

 

From heat pumps, ventilation to hot water heat pumps and underfloor heating, we’ve got a solution for every season.
