Types of Air Conditioners

There are more types of residential air conditioners on the market than what you might think!
The three most popular types of home air conditioners in Ottawa are:

The most common type of air conditioning in Ottawa homes is central air conditioners. These allow you to cool your entire home using the existing ductwork connected to your furnace.

A central AC air conditioner works to cool your home both by dehumidifying it, and then blowing cool air through it. It does this using two main parts; the outdoor unit which contains the motor and condensing coil, and the evaporator coil that’s inside your ductwork, typically right above your furnace. Together, they form a closed loop system that circulates refrigerant. As the warm air passes over the indoor coil it cools down, and then makes its way through the ductwork into your home through the vents.

In nearly all cases, your air conditioner will use the same thermostat as your furnace. It is typically set to Cool for the summer months to control the air conditioned, and will need to be swapped over to Heat again as colder fall days approach. Some thermostats allow for both Heat and Cool mode to be present at the same time to regulate both the upper and lower indoor temperature thresholds.

Homeowners are advised to replace their central air conditioner and furnace or air handler at the same time. This maximizes system dependability since both primary pieces are the same age. Secondarily, it increases efficiency since newer equipment works best when paired with new equipment; in some cases – like communicating equipment – it’s necessary. There can also be cost savings when replacing the entire system together rather than separately since some of the labour can be saved when the air conditioning system and furnace are changed at the same time. However, when adding a central air conditioner for the first time, there’s no need to replace your furnace if it’s been recently installed and in good condition. If you’re thinking about adding AC to your home, it’s a good time to act now! A Comfort Advisor can answer more specific questions about air conditioner installation and compatibility during an on-site assessment.

Central air conditioners typically last between 10 to 15 or more years depending on the completion of regular maintenance and the quality of the installation. More frequent air conditioner repairs will be required as the system ages. Get your Free AC Buyers Guide for complete details

As more people become motivated to use increasingly eco-friendly mechanical systems, we will see an increase in more homes switching to a heat pump to replace their air conditioner. The greatest benefit of heat pumps is the ability to function as an air conditioner replacement!

Heat Pumps work just like central air conditioners with a unit outside that connects to a coil above your existing furnace. In the summer time the Heat Pump dumps the hot air outside and the cool air inside – in the winter time it works in reverse dumping the cold air outside and the warm air inside to heat your home.

Heat Pumps used to be very costly and not practical for use in Canada until recently, as new heat pumps can provide heat when it is as low as -10°Celsius outside (newer cold climate rated heat pumps can continue providing heat with outdoor temperatures as low as -25°C or -30°C – via a major manufacturer)

Heat pumps – like ALL air conditioners listed – operate on electricity. The higher the efficiency the lower the electrical usage (meaning a lower hydro bill). The higher the efficiency the higher the price tag so you have to find that perfect balance of what will minimize your carbon footprint without costing you more in the long run.

A split ductless heatpump, also known as a ductless heat pump, is the best solution if you DO NOT have existing duct work. This is common in older homes (heritage homes) and homes built with hydronic heating systems (boilers, radiant floor heating and radiators).  When there is no duct work existing a split ductless air conditioner is the perfect solution.

It works like a central air conditioner with an outdoor unit for dumping the hot air outside that is connected by a refrigerant line to a self contained indoor unit called a head. These units are available in multiple heads (this way you can have an AC head in each necessary room of the house). Each head is independently controlled with its own remote controller so you can adjust different temperatures for different rooms for maximum comfort.

Your home’s size and layout, as well as your budget, will impact which home cooling solution is best for you. Each type of air conditioner has its own benefits, all of which provide the following benefits:

We used Francis Plumbing & Heating in the fall to replace our hot water tank and furnace in the same week after a friend recommended them. The experience was very smooth, professional, efficient, and the jobs were done on time, cleanly and were well priced. We also just had our air conditioner die in the first heat wave of the season and did not hesitate for a second before calling up Francis Plumbing & Heating. Once again, they delivered with exceptional responsiveness, quality, and value. Every one we've dealt with from that first phone call to receive a quote, to working with admin for payment and scheduling, to the employees in our home doing the installation have been amazing; so polite and friendly, so knowledgeable and helpful, so hardworking and efficient. HVAC and plumbing jobs are never fun because they are inconvenient and tend to cost a lot but Francis Plumbing & Heating Ltd has made our experiences very positive! We 10/10 recommend them.

Francis Plumbing & Heating has impressed me with their courteous and professional service from initial quote with advice that saved us hundreds of dollars and felt more like a masterclass in heating and ventilation than a sales pitch (thanks Ray) to follow-up communication without pressure from Ray and Jeff, to personal-touch front-office booking and communication, all the way to COVID-19 precautions during installation and obvious pride of workmanship from the technicians involved (Jeff, Ian, and Jordan H). The prices are fair, and competitive. The quality of the workmanship is top-notch. The customer service leaves the impression that Francis Plumbing & Heating is a reputable company is proud of their reputation, but doesn't rest on their laurels, and sees every project as an opportunity to earn your respect and future business.

Francis Plumbing was great! I was able to get the installation just a few days after my quote. Ian and Ray were great during the installation process, and when we discovered an issue with the installation, they were able to find me a suitable alternative and still install it on the same day.

We have used Francis Plumbing & Heating for three years now and have no regrets using them on each and every project. They are a stellar team of professionals I would 100% recommend to anyone looking for work to be done. They helped us on our new home to assess the plumbing, install outdoor faucets, get a new efficient water heater in, and to help us connect all our new appliances. We've had them back for furnace maintenance, new faucets, new toilets, etc. This week they installed a heat pump system for us and helped manage all the work to have an energy assessment for the available rebates. The new heat pump is amazing - quiet, efficient, and functions so well. The team at Francis is always friendly, kind, professional, and careful. They do clean work that is always really well managed, and they clean up fully after all their work. They are a fantastic group who communicates clearly, who let us know our options, and offer great financing too. We would work with no one else.

Air Conditioning FAQs

If you don’t have existing ductwork, a split ductless air conditioner is the ideal solution for your home. These systems consist of an outdoor unit and one or more indoor units, connected by refrigerant lines. They offer several advantages, including easy air conditioner installation, zone-based cooling, and increased energy efficiency. Additionally, split ductless ACs provide flexibility in terms of placement and can be a cost-effective option for cooling specific areas or entire homes without the need for extensive ductwork installation.

Central air conditioners utilize existing ductwork connected to your furnace to cool your entire home. They consist of an outdoor unit that removes hot air and a coil above your furnace that blows cold air through the ductwork.

No, a heat pump cannot fully replace both the air conditioner and the furnace. While it provides cooling in summer and heating in spring/fall, it’s not recommended as the sole heating source in extremely cold weather. It’s advisable to have a backup system, such as a hybrid (with a gas furnace backup) or full electric setup (with options like duct heaters, electric furnaces, fan coils, or baseboard heaters) for efficient heating during colder months.

Installing a heat pump can significantly reduce your carbon footprint and lower your energy consumption. It provides both cooling and heating, making it a more eco-friendly and budget friendly alternative. The Federal Government has provided incentives to homeowners looking to upgrade to a heat pump due to their high levels of efficiency.

On average, central air conditioners last between 10 to 20 years, depending on the unit’s quality, regular maintenance, and installation quality. More frequent ac repairs will be required as the system ages. 

Yes, you can upgrade your existing air conditioning system to a more energy-efficient model. Consider top-rated brands like Carrier, Trane, and Daikin for high-efficiency options. Heat pumps, which provide both cooling and heating, are also excellent choices for energy efficiency and year-round comfort.

Our professional estimator will assess your home’s size, layout, insulation, and other factors to recommend the appropriate size of air conditioner that suits your needs. Having a professional assess your home and calculate heat loss and air flow is crucial to ensure that you select the right-sized unit, as choosing an incorrect AC size can result in reduced lifespan of the unit and higher utility expenses due to inadequate cooling of your home.

Absolutely! Upgrading to a more energy-efficient air conditioning system, like a heat pump, can save you money on energy bills. Heat pumps provide year-round cooling and heating, and they qualify for grants, further enhancing your savings potential!

There are many factors that can affect an air conditioner’s performance — some issues can be resolved by basic troubleshooting but some problems are more complicated and must be examined by a licensed technician. If you’re having issues turning on your air conditioner, try the following:

  • Check for blown fuses or tripped circuit breakers
  • Check your thermostat to see it is on, set on cooling mode, and not reporting any errors
  • Ensure all vents and registers and not blocked and have proper airflow
  • Replace your air filter if it is dirty
  • Examine the condenser on the side of your home — see if there is any grass, weeds, leaves, or other objects that are on the unit

If you are still having issues, please Call Us. Our professional air conditioner repair services are here to keep you cool and comfortable

An air conditioner leak can be caused by multiple issues, such as improper installation, clogged drainage, old pipes, and even improper airflow. Also, leaked refrigerant is a cause for concern as exposure to the liquid is dangerous to your health. Phone a local ac repair technician immediately in order to determine the root of the problem and have it resolved.

Buying a new air conditioner to replace an older one that is near the end of its life is typically the best option for homeowners. Newer equipment is more energy efficient than older cooling systems, therefore when your air conditioner is starting to get old and is not functioning at its highest ability, you may actually save more money while still getting a drastic performance increase. Additionally, more frequent ac repairs will be required as the system ages. Contact a licensed ac repair technician to evaluate your current situation as in some cases the money saved on your utility bill may pay back what you’ve paid for a new air conditioner within years!

The suggested time frame to change your air conditioner’s air filter is every 3 months, but realistically an air filter should be checked every month and replaced if it looks dirty enough to restrict airflow.
