What Are HVAC Services?
A Breakdown of Installation, Maintenance & Repairs
Whether you are a homeowner, a business owner or a property manager in Nova Scotia, you have more than likely heard the word HVAC used in conversation. HVAC refers to the Heating, Ventilation and Air Conditioning we use to regulate indoor temperature, air quality and humidity. During Canada’s long, hot summers and even longer, colder winters, HVAC systems are what make buildings habitable, safe and comfortable 12 months of the year.
Here is anything and everything you need to know about HVAC service – the three pillars of the industry: installation, maintenance and repair. Whether you are furnishing a brand new building in Halifax or simply ensuring your system doesn’t leave you stranded on that hottest day ever in Bedford – this article will help you understand what makes a successful HVAC system.
Why HVAC Systems Are Essential in Every Building
Before we move on to the services themselves, it’s worth wrapping our heads around just how important HVAC systems are, not just for comfort, but for health and safety too.
1. Climate Control
Just as it controls indoor temperature, your HVAC system cleans the air of dust, allergens and pollutants. Without ventilation and filtration, indoor air can become stale, contaminated and possibly even dangerous for individuals with respiratory issues in particular.
2. Air Quality Control
Just as it controls indoor temperature, your HVAC system cleans the air of dust, allergens and pollutants. Without ventilation and filtration, indoor air can become stale, contaminated and possibly even dangerous for individuals with respiratory issues in particular.
3. Energy Efficiency
HVAC systems are engineered to be efficient, meaning less energy is wasted. This is good news for budget and environmental reasons. Newer systems are being devised to waste even less and control temperatures much better thanks to innovations like smart thermostats and zoned systems.
4. Humidity Control
Too much humidity like in Bedford can lead to mold growth, damage to furniture/appliances, while not enough humidity can cause skin to dry out and discomfort. HVAC systems make sure this improper balance does not happen.
Having established the foundation of what HVAC systems are responsible for, we can break down what HVAC services breakdown into pieces, starting with the first significant piece of the puzzle: installation.
HVAC Installation: Getting It Right from the Start
HVAC installation isn’t just the placement of a few machines. It’s a specialized and complicated process that must be customized to fit the particular use, configuration and local conditions of each structure.
What Happens During HVAC Installation?
When you hire professional HVAC installers, here’s what typically happens:
- Assessment and load calculation: The technicians study the space and calculate the heat and cooling load, which determines the right size of equipment needed.
- Ductwork design & installation: Properly designed ductwork allows the air to balance through the house. Poor duct design in Halifax can result in temperature differences and lost energy.
- Selection of units: No two buildings in Nova Scotia have the same system, HVAC technicians will help you choose the most appropriate system for your space, including central AC, heat pump or a ductless mini-split system.
- Equipment installation: This includes the installation of air handlers, outdoor condensers, indoor evaporator coils, furnaces or heat pumps.
- Thermostat installation: New thermostats may include wifi-supported options with zoning or programmable features to help you save energy.
- Testing the system: After installation, the technicians will perform tests to ensure the system can operate safely and efficiently.
TYPES OF HVAC SYSTEMS:
- Split Systems – The indoor and outdoor units are separate. Split systems are the most common type found in residential installations.
- Packaged Units – A packaged unit is best for homes with no basement space or crawlspace. The unit is one single package system.
- Ductless Mini-Splits – A ductless mini-split system allows temperature control room by room without any ducting involved.
- Heat Pumps – Heat pump systems are used for both heating and cooling, energy efficient in warmer climates like Nova Scotia.
Why Professional Installations Matters:
Poor installation is one of the main causes of HVAC malfunction and inefficiencies. Installed correctly, your system will:
- Lasts Longer
- Run better
- Need fewer repairs
HVAC Maintenance: The Secret to System Longevity
After your HVAC system has been installed, the next step is maintenance: the oil changes of your car. Maintenance keeps things running smoothly and will save you from costly repairs in the future.
Benefits of Regular HVAC Maintenance:
→ Better Air Quality: Cleaner filters and other components means cleaner air in Bedford, Nova Scotia for you and your family.
→ Improved Energy Efficiency: Dirty parts or worn components require more effort from the system, which means using more energy.
→ Less Likely to Break: Regular inspections identify small issues before they develop into more significant (and more expensive) issues.
What’s Included in a Typical HVAC Maintenance Visit?
- Filter Replacement: A dirty air filter may obstruct airflow, hinder parts and put stress on the whole system.
- Coil and Fan Cleaning: Dust coats components, decreasing efficiency and can lead to overheating.
- Refrigerant Level Check: This assures your AC is working correctly, no leaks and cooling the home adequately.
- Drain line check: Prevents potential leaks and mold exposure from condensation.
- Thermostat Calibration: Make sure your system is indicating accurate temperatures.
- System Controls Check: Ensures each electrical connection is safe and functioning.
Recommended Schedule
- Typically twice, once in the spring (for cooling) and once in the fall (for heating).
- In states with warmer climates, like Nova Scotia, systems are running year-round. It is worth it to schedule quarterly checks.
HVAC Repairs: Fixing What’s Broken
No matter how well you maintain your HVAC unit in Canada, it will eventually need repairs. Whether it be a failing blower motor, refrigerant leaks or a bad thermostat, addressing the issue early can prevent the entire system from failing.
Common Issues that Need Repairs
- No Cool or Heat: This is usually because of refrigerant leaks, the compressor or potential thermostat issues.
- Strange Noises or Smells: Clattering, buzzing or burning smells indicate mechanical or electrical failures.
- Frequent Cycling: Your system could be too big or could have a sensor failure if it is cycling more than is typical.
- Water Leaks: Indoor leaks are related to some condensation issue or possible clogged drain lines.
- Unexpected High Energy Bills: If your HVAC system uses more energy than usual, it is typically a sign that something is wrong with the system.
When to Call for Emergency HVAC Repair
Don’t ignore the warning signs. You may need emergency service if:
- Your system has failed during extreme outside temperature
- There is smoke, sparks or burning smell
- You notice large amounts of water collecting around the equipment
- The system is creating loud, abnormal noises
A professional technician from Canada can quickly assess and diagnose the issue to repair it quickly; thus restoring comfort and safety to your home or building.
