We used City Energy to install a furnace during a renovation. We got quotes from 3 companies and City Energy was the most cost competitive and creative in configuring new ductwork in a tight space. We have used them twice for repairs on another furnace and both times they arrived quickly and carried out the repair professionally without trying to upsell us on a new furnace. Highly recommend.

Common air conditioning problems

Having a broken air conditioner is a fearful situation many homeowners face during the summer months. Air conditioning repair services are often needed at the worst times; during a heatwave, when you’re trying to save money, or when you just don’t have the time to be fiddling with your AC in hopes of finding and solving the problem.

Below is a list of common AC problems and their solutions, some of which can be solved DIY-style. 

If you’re experiencing this issue, there are two causes you can look for. First, your circuit breaker may have tripped. If this happens, your AC will essentially be unable to move air and cool it, though it is running.

Check your circuit breaker and reset it–that should fix your problem. As a second cause, the blower belt in your AC may have worn down. A loss of the blower fan would keep cool air from circulating through your home. In this scenario, the blower belt needs to be replaced.

The causes for this issue are slightly more complicated and often require the help of a professional at City Energy. If your AC refuses to power up, the circuit breaker may have tripped, wires may have disconnected, or there may be issues with your thermostat.

Problems with wiring and thermostats are best left to the professionals, but you can often reset or troubleshoot a tripped breaker on your own.

In this scenario, you’ll feel air coming from your vents and hear the tell-tale rumble of your air conditioner but won’t be getting that cool air you need. Blocked or clogged condenser coils could be causing this issue or low levels of refrigerant. Frozen evaporator coils could also be preventing cool air from cycling.

To fix these issues, you can gently clean the condenser coils and dethaw the evaporator coils if you notice ice on them. Dethawing usually takes 24 hours or more. For refrigerant refills, it’s best to get the help of one of our professionals to ensure the mixture and amount are both completely accurate.

The cause of low refrigerant is usually a leak or a coolant hose disconnection. Frozen indoor evaporator coils could be a sign of low refrigerant.

If you spot this sign or see coloured puddles beneath your outdoor unit, turn it off and call City Energy right away. Running your AC without proper levels of refrigerant is highly damaging.

But before you think about adding some, you’ll want a professional to identify and fix any leaks you have before new refrigerant is added. As you’d imagine, adding more refrigerant to a leaky unit won’t do much good.

An air conditioner that blows warm or hot air is usually suffering from problems with dirt or low levels of refrigerant. For this AC repair, you’ll first want to check your AC’s air filter.

Clean any dirt you see, or if it’s too far gone, replace it altogether. The ductwork in your house can become dirty as well, potentially to the point of blockages. A duct cleaning company can clear out excess dirt and debris from your ducts and allow your air conditioner to function as it should.

They’ll also be able to catch disconnects in your ducts, which could be keeping cool air from reaching you. Low refrigerant levels may also be the culprit–check your outer unit for signs of a leak. If you notice any, call a professional at City Energy right away.

Having an AC that won’t shut off is more common than you might think. This AC repair issue is often caused by electrical faults, usually stemming from your thermostat.

If left untreated, you could find yourself with massive cooling costs and a damaged AC unit.

To troubleshoot, first shut off your thermostat. Check your air filters too, as dirty filters may be causing your AC to overwork and never shut off.

If turning off the thermostat and replacing your air filters isn’t helping, the issue is likely an electrical one. Faulty or disconnected wiring could be the culprit, but you’ll need the help of a professional to properly diagnose and treat this issue.

This issue can stem from a variety of sources. It could be a lack of power or faulty wiring. In this case, the compressor won’t have the power it needs to run.

Similarly, blown fuses can be the culprit. Dirty air filters can overwork the compressor and cause it to shut off for safety reasons. Broken valves in refrigerant lines can also cause a compressor shut-off.

To fix these issues, you’ll first want to check that your AC unit is receiving power. Check the air filters next and clean or replace them. If you’re still out of luck, call for an AC repair service from City Energy. We’ll help identify and fix any valve or wiring issues you may have.

Though it’s normal for some moisture to hang around your AC unit, pools or puddles of water are not a good sign. These leaks can stem from blocked drainage pipes, faulty condensate pumps, or a disconnected drain line.

These issues can be fixed in a variety of ways; a DIY way to unclog a blocked drainage pipe is with a wet/dry vacuum. You can also clean the condensate line yourself and potentially reconnect a disconnected drain line.

To fix the condensate pumps of your AC, you may need a professional at City Energy as this issue is often more complicated.
