Air conditioner installation

We spend much time indoors, so you want to make it feel as comfortable as possible. This includes having the right temperature in your home all year round.

At First Choice Heating and Air Conditioning, we specialize in air conditioner installations. Using high-quality brands with a standard warranty, you can rest assured your new air conditioner will keep your home cool in summer, lasting for years to come.

When to Replace AC

Air conditioners have limited lifespans, so there will come a time when your air conditioner can't be repaired and will need to get replaced.

There are many signs to look out for when it's time to replace your air conditioning system:

  • Your energy bills are higher than usual
  • Your air conditioning system is older than 20 years
  • Air conditioner repairs are more frequent
  • You have regular refrigerant leaks or a lot of replacement parts
  • Your air conditioner is less able to generate cold air

To avoid air conditioner service replacement, ensure regular air conditioning system maintenance by contacting our team.

Finding the Right Air Conditioner to Meet Your Cooling Needs

If it's time to get your air conditioner replaced, you want to ensure the new air conditioner installation is done correctly and efficiently. You can count on us at First Choice Heating and Air Conditioning to ensure the new air conditioning system is right for you.

Our knowledgeable team will:

  • Ensure the air conditioning system is the right size by using the square footage of your home or office, providing a successful air conditioner installation process. This prevents the unit from wearing out faster, affecting the humidity levels indoors, or wasting energy;
  • Ensure the air conditioner is energy efficient. An energy-efficient air conditioning unit uses less energy, reduces monthly energy costs, and is environmentally friendly;
  • Prioritize noise sensitivity when choosing the right air conditioning system for you.
  • Ensure your home is cooled in every area of your home or office, including the rooms that are typically warmer than others.

Had an issue with the old A/C not working texted Shane and he was by the next day. He seems to be available by phone, text email and whatsapp all the time and answers all questions. If I (customer) don't want something he will not push it on you. He is very hardworking, honest and knows what he is doing, and if somethings not right he will make sure it's right and explain the reasoning. Unit was 25 yrs old and had to be replaced due to old low refrigerant not widely available or used anymore and could have a leak. So the A/C unit + condenser and motherboard for it to communicate to the old furnace. I mentioned about different brands that I liked and disliked and no pressure on choosing which one. We worked out a deal and the install was completed successfully. I highly recommend Shane for any HVAC gas, A/C, or heating work.

We called Shane recently when we discovered our hot water tank was leaking from the base. He came immediately, diagnosed the problem and offered us solutions. With his help we decided on a Rinnai tankless heater and 2 days later he installed it!! His work was excellent, his prices very fair, he's great to deal with, and best of all he came by a couple of days later to check that everything was working fine and we were happy with his job. So yes, we'll happily recommend him to anyone needing their HVAC serviced/repaired! Thank you, Shane!!!

Shane from First Choice replaced our 40 year old furnace which had died. Since this was a no heat situation he changed his schedule so that he could service our home. He is very knowledgeable helped us in the decision-making process on what size of furnace to get. He didn't try to oversell us rather educated us on what was required. I had a great experience with him I would highly recommend Shane for any of your HVAC needs.
