A new air conditioning system is one of the smartest things that you can invest in the comfort of your home, but only if it’s done right. An incorrect unit size, improper installation or an unlicensed contractor can cause years of headaches: rooms that never cool correctly, energy costs that continuously rise and warranty claims that are denied due to the install not being done to the manufacturers specifications.
For more than 20 years, BOS Plumbing and Drains has been servicing the air conditioner installation in the GTA. We have hundreds of homes and commercial properties installed throughout the City of Mississauga, as well as in other areas in and around the GTA such as Oakville, Hamilton, Milton, Niagara, Cambridge and more. We take the same detail oriented, licensed approach to each and every job. With AC installation near me, one should not settle for the nearest truck out there. You should want a team that has the experience, credentials and reputation behind all their promises.
That’s what BOS delivers.
The solution isn’t necessarily the same for every home. Our technicians measure your square footage, the height of your ceilings, ceiling insulation, window orientation, ductwork and your family’s cooling needs before recommending any solutions. Let’s take a look at each of the types of systems we install and for which they are recommended for:
Expert solutions for all your residential & commercial plumbing needs
We serve the Greater Toronto Area and surrounding regions with local expertise
In the GTA where people have a forced-air furnace, the most popular option for central air conditioner installation. Warm air circulates through return air ducts, passes through the evaporator coil for cooling, and is then pushed through current supply air ducts for the whole home, dependable cooling with consistent quiet operation. The rule is, it’s all about size. If the unit is oversized it will short cycle and cause humidity and mechanical issues. If you have an undersized unit, it will be running all of the time and still will not be able to keep up on the hottest days. Our techs will do a complete Manual J load calculation on each job to eliminate any guesswork completely.
Mini splits AC system (mini ductless ac) is one of the most popular cooling systems in the GTA. If your home has no ductwork, if you’re cooling a newer addition, a finished basement, a detached garage, or a home office, ductless ac installation is often the most practical and energy-efficient path forward. No ductwork, no major construction, no mess, a wall mounted indoor air handler is connected to a small outdoor condenser with refrigerant lines. Mini split installation can be done in just one day, and it comes with excellent energy efficiency ratings, as well as a precise cooling system for each room and silent operation.
Multi-zone mini ductless ac systems bring together multiple indoor air handlers to a single outdoor unit in larger homes or properties which often have significantly varying cooling requirements between different rooms. They work on their own so if you want to have a comfortable bedroom you don’t have to cool an empty room. One of the most efficient options to choose from, and a good investment for houses that don’t have ductwork.
The split ac installation puts the noisier mechanical parts, like compressor and condenser, to the outdoor air conditioner, and makes the indoor part almost silent. They complement air handlers, and are ideal for residential and light commercial applications where noise level and efficiency are important considerations.
Whether you have a specific ac unit system for your home, BOS handles ac unit installation across all types and brands including Carrier, Lennox, Trane, Daikin, Goodman, Mitsubishi, LG, Rheem, York, Fujitsu, Samsung, and more.
Homes across the Greater Toronto Area all have different cooling challenges depending on their age, construction style, insulation quality, and existing HVAC infrastructure. That is why every air conditioner installation should be customized to the property instead of using a one-size-fits-all approach.
Some of the most common GTA installation challenges include:
The professionals know that every home in the GTA has different cooling requirements and we offer well-designed cooling ac installation near me solutions that are developed for the weather conditions in Ontario and the types of homes here.
A lot of homeowners put a lot of time into researching the best air conditioner unit to buy based on SEER ratings, brand and so on and then forget that the installation itself has a significant impact on the air conditioner’s performance. The truth is that a high quality unit, when it is not installed correctly, will always be worse than a lower quality unit, when it is installed correctly.
Here’s what poor aircon installation costs you in the real world:
Inefficient Cooling And Energy Costs:
The system has to work harder than it needs to due to incorrect refrigerant charge, improper airflow or duct not connecting well. It will be in your Hydro Bill each month.
Bad Installations Lead To Persistent Ac Troubleshooting Problems:
Good installations don’t lead to those problems. AC fan not working properly, leaking Air Conditioner problem due to improper sloping of the Condensate drain lines and ac is making loud noise from vibration due to improper mounting. You will not solve them with service calls, they are installation problems, not equipment problems.
Central Ac Not Cooling Evenly:
Rooms on the second floor are very hot, first floor okay – is usually a duct balancing or sizing problem and not a problem with the equipment.
Voided Manufacturer Warranty:
Most of the top AC manufacturers have a requirement that the installation be done by a licensed contractor. An improperly installed or unlicensed home before the first summer is over, means that your warranty is null and void.
Reduced System Life:
System parts are subjected to an improper installation and need to be replaced far earlier than their replacement date. A 15 year system may require significant repair after seven years.
Step 1: Full Home & Site Assessment:
We begin by fully assessing your home prior to recommending anything. We consider square footage, room configuration, ceiling heights, insulation, window exposure, the current plumbing system and HVAC infrastructure and your current energy usage habits. In addition, for ductless ac installation or mini split installation we take into consideration wall/ceiling mounting locations, refrigerant line routing, and options for the placement of an outdoor condenser.
Step 2 System Recommendation & Upfront Quote:
We go through the load and analysis and recommend the appropriate systems available to you, your budget and your home. A quotation is provided before any work is undertaken, detailing all equipment, labour and any plumbing repair and/or electrical work identified as a result of the assessment. No hidden catches when it comes to invoices.
Step 3 Licensed Installation:
All ac unit installation indoor and outdoor equipment is mounted by our certified technicians with all the necessary steps taken to run and insulate the refrigerant lines, make all electrical connections, connect the condensate drain and test, and integrate with the thermostat or smart home control systems. We also take care of all the duct connections during the central air conditioner installation and ensure that they are properly connected to avoid air leakage.
Step 4 System Start-Up & Commissioning:
Once installed we check refrigerant charge, test all electrical connections under load, confirm air flow from each of the air supply registers and test the condensate drainage under load. We start the system and go through a complete cooling cycle before we sign off.
Step 5 Walkthrough, Warranty & Rebate Documentation:
This one takes you on a walkthrough of how to use your new system, lets you know what to expect for maintenance and ensures you have all the documentation you may need for warranty registration with the manufacturer. We also do the paperwork to take advantage of any available government rebate for energy-efficient equipment in the State of Ontario that qualifies.
One of the most crucial aspects of having a successful air conditioner installation is deciding on the right size system. While some people think it’s a better idea to get a larger unit, it can result in uneven cooling, humidity issues and higher energy costs. If the system is too small, however, it may run continuously without cooling your home in the hot summer months in Ontario.
As experienced professionals in the field, BOS Plumbing & Drains techs conduct thorough load calculations prior to all ac installation jobs. We’ll make a house call to measure the square footage, insulation, ceiling height, window count, sun exposure, ductwork condition and room layout to size the system. For any size of cooling system, whether it’s a mini split installation system, a central air conditioning installation, or a big commercial system proper sizing ensures maximum comfort, efficiency and low long term operating costs.
Not all calls we receive will be for a brand new installation. Homeowners may be struggling with the dilemma of repair vs. replace for an older system. This is the straightforward approach our techs take when having this discussion:
In general, repair is the better choice if the cost of repair is less than 30 – 40% of the replacement value of your system and it is less than 8 years old. When your system is over 12-15 years old, needs regular maintenance, and is losing efficiency, it’s often a better financial move to replacing AC unit, particularly when you consider its efficiency in comparison to systems a decade ago.
Specific signs that replacement is the right call:
Your air conditioner is not working
properly on a consistent basis year after year, and is making several trips to the service centre in the summer. Repairing these components quickly adds up and oftentimes is not solving the actual problem of an old system reaching end of life.
Central ac not cooling
evenly or consistently throughout the house even after they are serviced and refrigerant is added. If the compressor is older, its performance is likely to be degraded and its coils may be damaged and will not be economically repaired.
Your ac is making loud noise
persistent, grinding or rattling, the problem is most likely not something that is easily fixed, and is actually a problem with the components of the system.
Leaking air conditioner:
Older coils are likely to have corroded evaporator coils due to the formicary corrosion, and leaking A/C refrigerant from these coils is usually not a cost-effective repair, particularly when it comes to the cost of refrigerant.
Your energy bills keep climbing:
You are still paying a higher energy bill even when you don’t use any more, which means your system isn’t as efficient as it used to be and is working much harder to keep the temperature regulated.
This is always a clear question that our technicians will always answer. We will let you know if a repair is warranted. We will make it an easy decision if replacing ac units is a better option, we will tell you why.
