We Install and Service Mini Split Heat Pumps

Gaining popularity in residential construction are Mini Split Heat Pumps. Heat Pumps are a highly efficient alternative to conventional home heating methods, and are perfect for the Newfoundland climate as they provide warm, comfortable heat to your home in the winter months, but also offer cool air conditioned air in the warm summer. Ideal for year round comfort! Northridge Developments has a team of technicians who specialize in the installation, and servicing, of air to air heat pumps. Whether you are building a new home, or looking to upgrade your existing home heating system, a Heat Pump is your ideal option. Please give us a call today to discuss how we can make this work for you!

Technically speaking, a heat pump is a mechanical-compression cycle refrigeration system that can be reversed to either heat or cool a space. The most common type of heat pump configuration is what is called a “Mini Split”. This simply means your home heating system will have components on both the inside and outside of your home. The heat pump unit itself will sit outside your home, similar to a central air conditioning unit. Inside your home you’ll find the wall mounted units that will blow your warm or cool air around your home. Mini split heat pumps systems can be installed in new construction, or existing home can be retrofitted to accept this system.

Think of a heat pump as a heat transporter, constantly moving warm air from one place to another, to where it is needed, or to where it is not needed, depending on the season and outside conditions. Heat energy is found everywhere, even in cold air. When it’s cold outside, a heat pump extracts this outside heat and transfers it inside. When it’s warm outside, it reverses directions and acts like an air conditioner, removing the heat from your home and transferring it outside. An advantage of a heat pump is that heat pumps transfer heat, as opposed to generating heat, which offers better energy efficiency. Another advantage of heat pumps is they are powered by electricity, so the need for fuel consumption is eliminated. Heat pumps systems are often used along with a supplemental heating source in our cold climate, and can offer a significant drop in your home heating bill.

When my hot water tank failed on a cold day in February, Northwest Plumbing responded immediately in assessing my needs, and installed a new tank. They cleaned up, removed the old one, and left my basement neat as can be. First rate service!

What a winter! Plugged sewer, frozen sewer, flooded house, and then back to a plugged sewer.

We called Northwest Plumbing and Heating and they came out the same day to do a scope and snake on our sewer issue. They were able to show us in 15 minutes what other people weren’t able to do at all. After doing much research to alleviate this situation and speaking with Baron, we decided that a new sewage lift system was definitely the way to deal with our issue. The next day I called Bill to set up the installation of a new sewage lift system and now within a week of being installed it is working perfectly. The only reason for delay of a week was due to 100+km winds and our excavating team not able to dig up our sewer line.

We cannot say enough about the customer service Bill, Baron, and Andrew showed us during this extremely stressful time. We would highly recommend Northwest Plumbing & Heating for any issues that you are having. They have been personable, efficient, and very professional in all our dealings with them. 5 star service!

Whether it be through my business or residence they have always been great. They have responded to all my calls respectively in nature and in the time they said they would. Their workmanship and experience are second to none. The cost of material and labour are also in line with, if not better than, other companies in this field. The staff are knowledgeable, experienced, and courteous. This is the one and only company I deal with in the plumbing business in Corner Brook. I recommend this company to other people 100% of the time. #1 in my mind.
