Learn to Avoid Serious Repair Issues

A malfunctioning commercial freezer or cooler can cause serious issues for restaurants and commercial businesses that depend on their equipment to store food products. It’s recommended to have regularly scheduled refrigeration maintenance to keep it running in good order and to extend the life of your equipment.

Even with regular maintenance, equipment can still fail and breakdown. Oftentimes there are warning signs or indicators that can signal you need to call for repair. It’s critical to call as soon as you realize something is amiss to avoid a small issue turning into a major crisis.

I found Stat online, their reviews were a solid 5/5 stars based on 37 reviews. I’m 38! Too bad you can’t give them more stars, they earned it!The level of professionalism from my first phone call with John, to having Liam show up on site, was top notch. Liam arrived to site early, was very polite, and displayed 10/10 professionalism and expertise from start to finish.Can’t say enough good stuff about these guys, I’ll be a repeat client for sure.Shaun

STAT Climate Control Solutions did a really good job installing my AC unit, even though it wasn’t the easiest setup. My basement is a finished legal suite, and the mechanical room was on the other side of the suite. They had to go through the ceiling of one of the rooms to pass the pipes and electrical wiring from the mechanical room to the outdoor unit.Even with the tricky setup, they made it work and did the job really well. Super professional, efficient, and clearly knew what they were doing as they also took time to explain everything I needed to know.If you need HVAC services, I highly recommend them!

We were firing up the A/C units for the summer, but something was not quite right. Called STAT because their sticker was on the units, and received a very warm welcome and a quick appointment date. Technician was right on time and knew what he was looking for and doing. Repaired some miswiring from a previous tech who had changed the thermostat for heat during the middle of the winter. Fired everything up and measured pressure, temperature on each air outlet, and overall air flow. Cleanup up the furnaces and filters while he was at it. Still had timeleft over on his basic time allotmentso he checked the outdoor condenser air flows and touched up the coils. System chugged away like a charm all summer.We will definitely call them back here next Spring. Well managed company with great staff! Thank You!

Scheduling an appointment was easy, accommodated our emergency request - HVAC wasn’t working and we were having an event.Mike, the technician, came within 30 minutes, did not wasted any time and directly went into the work. Diagnosed the problem and went ahead with resolving the issue. He is a knowledgeable person and could see his interest. Also taught us on how to do basic maintenance of the HVAC.Issued fixed in 2 hours.We are a happy customer!

So I own a condo, and it turns out that companies that can work on condo units are not all that common.Fortunately, Stat Climate rescued me when I was having trouble with my AC unit.Chris was super helpful, gave me some tips on keeping things in working order, and got everything sorted on time and for the price quoted.Will definitely be using them in the future and I can definitely recommend them for your service needs.Thank you!

I was debating between a 4* and 5* review. There was an initial issue with the appointment but I have to admit STAT pulled all stops when they realized their mistake and did right by the customer. I was especially impressed with the service tech (Delaine N.); the problem was intermittent and difficult to pin down. I do have a basic understanding of electrical wiring and Delaine went through his analysis with me and ensure I clearly knew what he was doing and why. He was finally able to pinpoint the problem after much back and forth analysis and testing and I now have a much better understanding of my HVAC system.5 stars - solid.

Called for an emergency furnace repair for one of my rental properties after hours and the technician was quick and honest. After reviewing my options I decided to go with a new high efficiency furnace. The installation team was friendly and did a fantastic job on the installation. The office and comfort advisor walked me through the whole process very professionally and even the owner called to follow up with me. I will definitely recommend Stat to all of my families and friends.

Warning Signs for Equipment Malfunction

Build-up of Frost

A build-up of frost is common and is an early sign that something is not quite right with your refrigeration unit.

Frost can come from a number of factors including:

  • Humidity changes
  • Faulty pressure relief valve
  • Damaged or expired gaskets
  • Insulation issues
  • Freezer door being left open too long
  • Freezer door not sealing correctly

Frost build-up on or around the evaporator coil may be indicative of a problem with the fan or its electronic components.

In addition to frost build-up indicating a mechanical issue(s), it is also a sure sign that the refrigeration unit is increasing your energy bill as it is working inefficiently.

Noticeable Temperature Fluctuations

Food must be kept at a consistent temperature and with less cycling (on and off) your refrigeration unit uses less energy. Temperature fluctuations can be due in part to:
  • Compressor malfunctioning
  • Faulty temperature gauge – can be verified with a thermometer
  • Dirty or defective fan
  • Refrigeration unit door being left open too long
  • Refrigeration unit door not sealing correctly
  • Damaged sensor
  • Dirty condenser coils
  • Cool air not circulating – too much food being stored
  • Failed electrical component(s)

Odour Issue

Commercial refrigeration units are not manufactured with mechanical parts that cause an unpleasant odour. Most often, an odour is the result of food that is spoiled or rotting somewhere on or around the refrigeration unit. Once you have eliminated this possibility then you can determine the smell is the result of something more serious.

Odd odours that indicate something is faulty may be caused by:

Unusual or Strange Noise

A noticeable noise coming from your refrigeration unit is most often indicative of something that needs repair. It’s important to identify and correct the problem as soon as possible to alleviate the potential of something more serious, and expensive, developing if left unattended.

Water Leaks

Generally speaking water leakage is usually an easy, inexpensive fix, although it can also be an indicator of something more serious. The most common causes of water leakage can include:
  • Worn out seals
  • Damaged water lines
  • Clogged or frozen water lines
  • Blocked defrost drain
  • Drain pan is tilted and overflowing

Best Practice to Reduce Refrigeration Repair

It’s best to deal with any anomalies that you detect with your refrigeration unit which will not only increase it’s lifespan but also reduce the repair cost if it’s not left unattended.

To increase the odds for maximum efficiency and long term operation it’s recommended you schedule regular maintenance – the investment will save you money in the future.
