We recently had a great experience with Delta Air Systems in repairing our air conditioner. From the initial call, to arrival confirmation and the work that the techs did, the entire process was smooth and left us with a working AC!I was impressed that even after the issue was fixed, the techs took the time to inspect the entire system.We have a Carrier system and I wouldn't hesitate to call Delta Air Systems again for help.

Delta Air Systems provided me with great service and answered all my enquiries quickly. Jason went over all the options with me and ensured to find a solid system for a great deal. They came next day and completed the work in a single day. Savannah made sure to cover all my floors in order to protect them, and the wiring for the unit is impeccable. Rick ensured the installation of the heat pump was exactly how I wanted it and Kyle ensured to go over the system and the thermostat to ensure I knew what to expect moving forward.I would highly recommend Delta Air Systems to anyone looking for a local reliable and professional HVAC company.

Couldn't have asked for a better experience from start to finish! Tanya was very helpful and responsive during the entire quoting process, and even helped resolve a last minute install change I wanted to make. After chatting with the install crew and her, within 5 minutes, they had confirmed the change and it was underway with no Hassel whatsoever.Scott, Savanah, and Jay were all extremely professional while installing our new heat pump and air handler. They were respectful of our house and the entire system looks great. Very clean lines and ductwork.Overall, I would highly recommend working with Delta. It's rare to find such a great team like this!

I recently had an issue with my thermostat and couldn’t switch it over as I had a Lennox AC/furnace so it wouldn’t take a regular thermostat. I called delta and the lady on the phone who helped me several times figuring it out was excellent. She was very informative and was not monotone, was a very pleasant conversation. She booked me in for the next opening. Braedon was the gentleman who serviced my furnace and thermostat. He was fantastic, friendly and did the servicing very quickly. Fantastic company I would totally recommend them.

Delta has done it again!2024:We reached out to Jordan again, this time for installation of an ERV (energy recovery ventilator). The ERV continuously exchanges air between outdoors and indoors, while recovering heat and moisture. In essence, it's a very efficient way of providing continuous fresh air for improved indoor air quality. We also had the exhaust fan upgraded in the basement bathroom, and had the central vac exhaust vented directly outdoors. The work is nice and tidy, much like our furnace/AC replacement in 2019. The new bathroom fan is much quieter and more powerful than the old one. The motion and humidity sensor is a nice touch. We also really appreciate the improved indoor air quality from the ERV unit. One little extra is that they were also able to fix our central vac canister in the garage (just needed one new part to get it running). Very pleased once again!2019:We reached out to Delta Air Systems to replace our very old and inefficient furnace and AC. The salesperson, Jordan, is clearly very passionate and knowledgeable. She met with us in our home for a free estimate, and carefully walked us through the world of furnaces, air conditioners, heat pumps, HRVs, air purification systems, and more. She was very patient in answering all our questions – and encouraged us to keep asking! She also included an extra reusable air filter (for which she was happy to shop around for us) in the quoted price!Jordan returned the morning of the installation to check in on things and answer any further questions we had. Scott and Liam worked very efficiently to complete the job in one day – but certainly not at the expense of workmanship. These guys are true professionals. Perhaps the best word to describe it is meticulous. In fact, our utility room has never looked better!The new system is extremely quiet – a HUGE improvement from what it replaced. We look forward to many years of quiet and efficient comfort!For all your heating, cooling, and air filtration needs in Waterloo Region, look no further than Delta Air Systems!

Amazing service! Knowledgeable staff & great customer service! Had a maintenance check for HVAC system recently; had a minor service call a couple of years ago for an overflowing a/c drain pipe due to extended hot days; had an installation to replace our old combi heating/cooling unit 4 years ago. Everyone there is always professional, helpful, polite & provides great advice. Technicians show up on time, respectful, answer questions & give valuable recommendations. Thank you for everyone's great work!

Young man was here to do an inspection on my furnace and air conditioner.He did an excellent job and I would be pleased to have him come back at anytime to do any work that is required!
18:33 14 Jan 24
Just like babies aren’t born during the day, when it’s convenient, our furnace waited until it was -11C to give out … and on a Sunday.  Nothing like a worried senior couple.I called the emergency line and Megan listened to me babble and was able to come within a ridiculously short period of time.This is a very experienced HVAC tech – she diagnosed the problem, swapped in a part and had the thing fixed in 10 minutes.  And used the spare time to inspect our coils.This is our second service call.  Braeden came to fix our first issue and he too was professional and competent (and polite).This is the best service experience we’ve had.  Having just moved here from Toronto we now depend on Delta Air Systems for our HVAC support. We highly recommend them.

We received fantastic service from the young lady who fixed our furnace. She was knowledgeable and professional, explained the issue to us and was luckily able to resolve the problem on the spot. She gave us some tips to extend the life of our furnace and the price for the service was very reasonable. We did not feel like there was any intent to upsell and believe the technician was working in our best interest to keep our 23 year old unit running as it is in good condition. I would highly recommend Delta as I felt the service provided was top notch.

I waited to review to see difference in utilities over past year. They installed 3 heat pumps in 110 year old house which was complicated due to renovations - getting heat/AC to each room. Jason; Scott; Tyler; Jordan; Zack were extremely helpful in placement of units for most efficient service installation in most unobtrusive place outside conduit and inside units. We have whole house AC now and radiators are augmented by heat pumps so more comfortable heat in an old house. Gas and hydro bills all reduced. As well, admin staff were very helpful. Excellent work and follow-up!! Thank you

My Lennox AC failed over the summer. Called around, decided to have Delta perform the service. Very friendly on the phone, I described the issue I was having. The technician was dispatched with the part available on the first visit. This saved time and money. Definitely calling them again for my future needs.

We inherited the HVAC system from a previous homeowner. One day, the A/C unit stopped working, and we made the mistake of calling the A*** O** company (the edits are mine). The company ran a diagnostic and told us that the motor, which pumps air, had failed and needed replacement. They quoted us $1600 for the replacement and also suggested that we might want to consider replacing the whole unit with one that would be covered by warranty. We spoke with their salesperson who tried hard to upsell us on a new air pump system, costing around $12k.Our second call was to Delta. The salesperson, Tanya, was very knowledgeable and explained that we didn't need any replacement as the unit was relatively new and was most likely still under warranty. They were able to verify this the next day and sent us a technician to replace the motor for free, charging us only for the labor.Amazing job, and thank you for keeping the customer's interests a priority!

Delta is our go to spot anytime we have issues with our AC or furnace. Our AC decided to break on us in the middle of a heat wave. The lady I spoke to on the phone with was very helpful and reassuring. The technician came out (I think his name was Liam?) and went above and beyond for us! He was friendly, professional and cleaned up really good after himself. Even our dog (who doesn’t care for people) absolutely loved him- so brownie points for that! Thank you Delta Air Systems Ltd!

We recently had an install of a tankless water heater, furnace, and heat pump from Delta. From a sales perspective, Jay was extremely responsive to all of our inquiries prior to purchasing. He is very kind, respectful, and knowledgeable. Having a background and experience in the trade certainly helped. Jay was able to thoroughly answer all of our questions and address our concerns. He provided us with comparisons of the units we were considering, his professional opinion, and a variety of options for us to consider. He educated us in the benefits of a heat pump. We were impressed that he was able to accommodate all of our last minute requests as well during and after install.During the install, Scott and Matt were timely, efficient, clean, and quiet. They were respectful of our home by using mats to walk on and always left things clean and tidy before leaving each day. They allowed for questioning throughout and provided detailed information regarding operating the equipment upon completion of the project.We would highly recommend Delta and had a pleasant experience working with each of the team members.Thank you 🙏

Due to some work completed by another service provider (sub-contracted), we were in a real pickle when we turned on the AC for the first time this year and it wasn't working. The "other guy" recommended full replacement of a 6 year old system. Delta diagnosed and determined parts were under warranty and replaced them in a timely fashion. From the first call with Annie, to our Technician Megan and communication with Jordan (apologies, the fellow who helped with the thermostat was great too), EVERYONE was super professional, helpful and went the extra mile(s) to make a really crumby situation less crumby. Our final bill was 1/3 of what we were told we were looking at for a full replacement. Thank you Delta Air!

This is the most fantastic company you will find. I had a new furnace and heat pump installed. Jason 1 was amazing in describing the benefits of the system I bought and Jason 2 did an amazing install job with his crew correcting the wiring errors of the previous company. Jordan personally came out along with Zack and provided me with all the information I needed re: the new Ecobee thermostat. This is the best company you will find!!!!

Heat Pump FAQs

How does a heat pump work?

A heat pump transfers heat from one place to another using a refrigeration cycle. It can both heat and cool a space by moving heat from a colder area to a warmer one, or vice versa.

In heating mode, a heat pump absorbs heat from the outdoor air, ground, or water source, then compresses and transfers the heat to an indoor coil. The heated refrigerant is then circulated inside the home.

In cooling mode, the process is reversed. Heat pumps absorb heat from the indoor air and release it outside, cooling the indoor air.

What are the different types of heat pumps?

There are several types of heat pumps, including:

  1. Air-source heat pumps
  2. Ground-source (geothermal) heat pumps
  3. Water-source heat pumps
  4. Hybrid heat pumps
  5. Ductless mini-split heat pumps

Each type of heat pump has its own advantages and disadvantages, and the best type for your home will depend on factors such as climate, the size of your home, and your heating and cooling needs. A Delta technician can help you determine what’s right for your home and needs.

What are the advantages of using a heat pump?

There are several advantages of using a heat pump for heating and cooling your home, including:

  • Energy efficiency
  • Cost savings
  • Dual function
  • Improved comfort
  • Environmentally friendly
  • Durability
  • Versatility

Are heat pumps cost-effective compared to traditional heating and cooling systems?

Heat pumps can be cost-effective compared to traditional heating and cooling systems.

Heat pumps can be more energy-efficient than traditional heating and cooling systems because they transfer heat rather than generate it. This means they can provide the same level of heating or cooling using less energy. Since they use less energy, you can save money on utilities. Additionally, because heat pumps provide both heating and cooling in one system, you don’t need separate systems, and that reduces installation and maintenance costs.

How efficient are heat pumps?

Heat pumps are generally more efficient than traditional heating and cooling systems, as they transfer heat rather than generate it. 

The efficiency of a heat pump can vary depending on several factors, including the type of heat pump, the size of the home, and the climate. Ultimately, air-source heat pumps can provide up to 50% in energy savings compared to traditional electric, oil or propane heating.

How do I choose the right size of heat pump for my home?

Choosing the right size of heat pump for your home is important to ensure that it can provide adequate heating and cooling without wasting energy or driving up your energy bills. A licensed technician can help determine the size of heat pump your home requires. 

Factors that affect this include:

  • Heat load of your home
  • Heat pump capacity

Can a heat pump be used in extremely cold climates?

Yes, heat pumps can be used in extremely cold climates, but they may not be as efficient as they are in milder climates. There are cold-climate heat pumps that work well in lower temperatures. If you live in an extremely cold climate, you might consider a dual-fuel heating system that combines a heat pump and a furnace.

How long does a heat pump typically last?

The lifespan of a heat pump typically ranges from 10 to 15 years, although some can last up to 20 years with proper maintenance. The lifespan can vary depending on factors such as the quality of the equipment, the level of usage, and the climate. Regular maintenance is important to ensure the longevity of a heat pump.

What’s the difference between a heat pump and an air conditioner?

The main difference between a heat pump and an air conditioner is that an air conditioner cannot heat your home like a heat pump can. Whereas a heat pump acts as both a heating and cooling system, an air conditioner is only able to cool your home.

How loud is a heat pump?

Heat pumps are designed to run quietly, though the level of noise depends a bit on the model, location, and installation. Most models make noise comparable to a fridge, with the outdoor unit being a little louder. In general, though, modern heat pumps are designed with advanced technology and materials to minimize noise.

Do I need a backup heating system with a heat pump?

Not necessarily. However, there are benefits of having a backup heat source. While heat pumps are designed to provide reliable heating in most climates, it may be advisable to have a backup heating system, particularly in areas with extreme winter weather or frequent power outages.

Another reason to have a backup source is efficiency. A hybrid system combines the efficiency of a heat pump and the power of a forced air system, like a furnace, for times when it’s extremely cold. Since heat pumps work most efficiently in more moderate climates, a furnace could be more efficient in extreme cold.

Can a heat pump work with a gas furnace as a backup heating system?

Yes. This would be what we referred to in the previous question as a hybrid heating system. It’s also called a dual-fuel system.

This type of system has advantages. By utilizing the heat pump’s efficiency during milder weather, homeowners could save on energy costs and reduce their carbon footprint. Meanwhile, the gas furnace provides reliable heating during colder weather, ensuring that the home stays warm during extreme temperatures.

Can I Repair or Install My Heat Pump Myself?

Thinking of repairing or installing your heat pump on your own? Safety should be your top concern, as heat pumps are complex systems that involve electrical components and intricate mechanisms. Attempting a DIY repair or hiring an inexperienced contractor or company can put you at risk of personal injury, electrical hazards, or creating a bigger problem. The intricate electrical and refrigerant systems involved in heat pumps demand precise calibration, which an untrained installer might overlook. A poorly installed heat pump can also result in a shorter lifespan, frequent breakdowns, and an invalid warranty. All of Delta’s expert technicians are carefully selected, trained and certified by Lennox and Daikin, ensuring their expertise in all the latest heat pump technology.
