Being a homeowner can mean having to make many large financial decisions even after the home has been purchased and the closing costs have finally been paid off. One such major expense I see more homeowners making is installing heat pumps, in particular retrofitting older homes with a ductless mini split system. We completed this task on our home in the winter of 2020 and you may be wondering if it was worth it? My answer is simple: YES!
Let me first mention the drawback, and it is a big one. Costs can vary but $10,000 is a good ballpark estimate for installing a mini-split system. While financing options are available and these units more than make up for it over time in energy savings there is no getting around the fact a significant upfront investment is involved. They are also not very attractive to a home’s decor (some recent models, however, look just like artwork on a wall) and while I have no issue with its appearance, others may not feel the same. As for the benefits, they are many and here are just a few:
Reduction in Heating Bills
The most obvious benefit can be seen in your heating bills, especially if you have an all-electric heating system like we did. Even considering that 2020 was the first winter we had a baby in the home and subsequently turned the heat up all day long, our power bill still dropped by almost 40% during the coldest months! Even in the summer we only went up about 15% and considering the incredible difference in comfort that was a price well worth paying. Given how energy costs are rapidly rising this is also a good buffer against sharp price increases.
Can Run Dual Heating & Cooling Duty
Heat pumps are basically Air Conditioners (or Refrigerators) that can be run in reverse, where the two heat exchangers switch between acting as an evaporator and condenser as the season (or in Nova Scotia, day) changes. As a result, they provide year-round comfort on even the coldest days. Even on those crazy weather days where we go from cold to hot to cold again, they can seamlessly switch between heating and cooling automatically and efficiently.
No Extraordinary Installation
As the name implies, ductless mini-splits do not use air ducts as working with existing ductwork is usually difficult due to density differences between hot and cold air. Side note: I once took a course on air system design and let’s just say it’s best to leave it to the pros! If there is room in the electrical panel then no complicated electrical work is necessary. Even the large amount of moisture removed by the system in the summertime usually drains outside without the need of a drain pan or other maintenance.
Easy to Maintain
While I always recommend an annual checkup by a qualified HVAC (Heating, Ventilation & Air Conditioning) technician, the only maintenance required by homeowners is to regularly clean/change the filters and keep snow and other debris away from the outside unit.
Like any appliance with a compressor, heat pumps make varying levels of noise. However, it is almost exclusively made outdoors, well away from the inside of the home. The noise level is comparable to a fan on the lowest setting most of the time and even at its worst it is barely noticeable.
The biggest myth I see about heat pumps is that they are not suitable for cold weather. The fact is some units can operate efficiently right down to about -26C/15F, which is more than adequate for even the coldest days in our Nova Scotia climate. Heat pump technology has grown by leaps and bounds in the last decade and will likely only improve over time. Do I recommend getting a heat pump installed if reasonably possible? You bet!
If you ever do research on how to become a home inspector or what makes a great home inspector, you will find lots of information on the benefits of having things like a construction, engineering or trades background or a strong eye for detail. One thing that rarely is discussed is the importance of communication: not only to explain potential issues we find but to put them into the proper context using our skills and knowledge. Here are some examples of statements that are 100% true, yet are very misleading:
Electric Heating is 100% Efficient
No high efficiency furnace or boiler can compete with electric heat, but this ignores the simple fact that electricity is usually produced by generators which are about 30% efficient. Overall, electric heating is the most inefficient and expensive way to heat a home.
Electrical Heating is the Most Inefficient and Expensive Way to Heat a Home
Again, this is correct on the surface but is misleading. There are a few advantages of electric heat: no oil or propane tanks are needed, they are easy and inexpensive to install, and they can be relatively easily added to cold areas of a home. They are also great for distant areas where heat is only needed sparingly, such as in a garage or workshop. In short, all heating sources have advantages and disadvantages and that is why there are so many different examples seen in homes.
Radon is a Radioactive, Tasteless, Odourless Gas That is Everywhere and There is No Safe Limit
You can also substitute "Carbon Monoxide” and this statement would again be true but misleading. Every single home has radon and while there is no agreed safe limit the Canadian guideline is 200 becquerels per cubic metre (200 Bq/m3) and no action is recommended unless the long-term levels in your home exceed this. I have discussed this in depth in a previous blog post, but the bottom line is radon can indeed be dangerous but, in many cases, it is not a concern.
Inside Edge Home Inspections Uses a Unlicensed Inspector
Sounds shocking that I would admit this is true until you learn that in Canada ALL inspectors outside of British Columbia and Alberta are unlicensed: a license not only is not required but does not exist. Furthermore, as of 2021, there are absolutely no requirements to anyone calling themselves a home inspector in any of the Atlantic Provinces. Our website demonstrates my impressive credentials and extensive experience, including completing 340 hours and counting of continuing education just in 2021 alone. If licensing becomes available our company will be first in line to sign up.
The reality is we are fully incorporated in Nova Scotia, our company is a certified member of InterNACHI, the world’s largest home inspection organization, and I am a Certified Professional Inspector with InterNACHI. Our passion is providing quality, independent home inspections and we fully support all efforts to raise the standards in our industry.
