How To Keep Your AC Healthy Between Service Visits In 4 Steps

July 28, 2026

Seasonal air conditioner maintenance (i.e. regular service visits) is the most important factor in extending the lifespan and maintaining the efficiency of your central air conditioning system. Ordinary wear and tear, especially dirt and grime buildup, can cause your AC to overwork, struggle, overheat and eventually break down.


A quick clean will help you catch any smaller problems before they become serious. Something as normal as a layer of leaves on your outdoor unit can eventually cause your entire system to fail. So, to keep everything in good shape, here are a few tips.

1. CHANGE YOUR FILTERS EVERY 4 WEEKS

This is the most important chore for your family’s health.


Old, dirty air filters don’t do their job. The air you breathe in your home won’t be as clean as it ought to be, which can lead to everything from excess dust to respiratory problems. Dirty air filters can also allow dirt and grime to build up in your ducts, lowering the overall efficiency of your system and harboring microbes and mites that can multiply and get into the air in your home.


Once a month, replace or clean your air filters.



  • For 1′′ filters, look for one that you can’t see through when you hold it up to the light to make sure it’s actually doing the job in the first place
  • For larger washable filters, thoroughly rinse and dry them every 30 days. Swapping between 2 filters every month is easiest.

2. KEEP THE DRAIN CLEAN AND CLEAR

As your air conditioner keeps the house cool, condensation builds up in the system and drains through a series of tubes. If left stagnant, these pipes grow mould and fungus, which can spread and clog your whole drainage system.


Once a year, as part of regular air conditioner maintenance, your Woodbridge GTA ClimateCare specialist brings a powerful vacuum to siphon everything out of the pipes.


To prevent gunk from growing, add 1/4 cup bleach mixed with 3/4 cup water directly to your drain line’s access port (usually a T-valve) every three months. If the plug on your access port has a wire coming out of it, switch off your air conditioner’s breaker before you remove the cap, and replace it when you’re done.

3. WASH OUT THAT CONDENSER

This is the most common reason we receive early summer emergency calls.


During the off-season, your condenser can get clogged with leaves, dirt, and other gunk. This hinders circulation and can actually prevent your air conditioning unit from cooling at all.

4. GIVE THE THERMOSTAT SOME NEW BATTERIES

Our technicians calibrate your thermostat as part of the annual air conditioner maintenance, and that includes fresh batteries. However, if it goes out between checkups, you can easily replace the batteries yourself.


Some thermostats have flip-open battery covers, but usually, you’ll have to gently pull the thermostat or its faceplate away from the wall. Just swap them out and pop the thermostat back in place—but make sure you shut off your thermostat’s breaker before you start to avoid getting shocked.


There you have it! You can help maintain your home comfort equipment between service visits without being an expert.

Installing modern air conditioning in older homes can be tricky, especially when trying to keep the original look and feel intact without major construction. Traditional HVAC solutions often fall short in addressing these issues effectively without compromising the historic value of the property. This is where the Unico System comes into play: a small-duct high velocity system with a minimal footprint. Keep reading to find out how Unico provides a totally viable AC solution for older homes. Many of these structures were built without the ductwork necessary for traditional central air systems, making standard installations difficult without significant modifications that could disrupt their integrity. Some of these challenges include: Structural Limitations: The lack of existing ductwork and the potential for structural damage from installing new ducts are major considerations. Preserving the Aesthetic: Maintaining the original appearance of old homes is often a priority. This can limit the types of air conditioning systems suitable for installation, as many require alterations that could permanently change character-defining features. Space Constraints: Older homes often have smaller rooms and less closet space, which complicates the installation of large indoor air conditioning units. Energy Efficiency Concerns: Many older homes are not as well-insulated as newer builds, which can lead to higher energy costs.

Winter is when your boiler works its hardest and when small issues can quickly turn into big problems. The last thing any homeowner wants is a heating failure during a cold snap. This is when service availability is notoriously limited, and repairs are often more urgent (and costly). Knowing these early boiler warning signs can help you address problems before they disrupt your comfort and your plans. Cold or Uneven Radiators If your boiler is running, but some radiators stay cold or only warm up partially, it’s a sign that something isn’t right. Common causes include trapped air in the system, sludge buildup, or circulation issues. Left unresolved, cold radiators force your boiler to work harder, increasing energy use and wear, often right when demand is highest. That very well may lead to failure when you need it most. Unusual Kettling or Rumbling Noises A boiler should run quietly. If you hear rumbling, whistling, or kettle-like noises, it usually means limescale is restricting water flow inside the heat exchanger. Scaling reduces efficiency and can lead to overheating or internal damage. During winter, these noises often worsen as the system runs more frequently. Only regular maintenance can keep this at bay. Pilot Light or Ignition Problems Older boilers rely on a pilot light, while newer systems use electronic ignition. If the pilot keeps going out, or your boiler displays error codes or fails to start, heating can stop entirely. Ignition issues won’t fix themselves. During cold snaps, a simple ignition fault can quickly turn into a no-heat emergency if ignored. Frequent On-and-Off Cycling A boiler that turns on and off repeatedly in short bursts is short-cycling. This can be caused by thermostat problems, incorrect sizing, pressure issues, or internal faults. Short-cycling increases fuel consumption and puts unnecessary strain on components, which is exactly what you want to avoid during extended winter use. Why You Don’t Want to Delay Boiler Repairs in Winter Even minor boiler problems tend to escalate faster in cold weather. Delays in repair can lead to: Higher heating bills Reduced system lifespan Sudden breakdowns during extreme cold Limited service availability around holidays Addressing warning signs - like the ones listed above - early helps protect your comfort and avoids last-minute repairs that cost a fortune. You Know Who to Call: Woodbridge GTA ClimateCare If you notice any of these signs, it’s best to have your boiler checked by a professional before winter conditions worsen.
