What Customers Say

“We have been customers of Boonstra Heating and Air Conditioning since the spring of 2018. We are very pleased with their ongoing service right from the start with installation of a new air conditioner, hot water heater and gas line through to ongoing yearly inspections of our heating and cooling systems. Most recently, they found a problem with our furnace heat exchanger. Andrew was very polite, professional and demonstrated a strong work ethic and efficiency from showing us the issue and promptly seeking out a replacement and installation all in the same day. This was a safety concern that was given the utmost priority by Boonstra. Thank you!”

- Julie H.

“We purchased a new furnace, air conditioner and tankless water heater last year from Boonstra because we have been really happy with their service over the years. At the time our existing humidifier was disconnected and we decided not to reinstall. However, this winter we realized that we need it. When we called Boonstra a service call was quickly arranged and our old humidifier was reinstalled free of charge. The service technician (Steven) was very friendly, professional, and did a great job. We’re very pleased with this experience. And it’s not dry in the house any more!”

Frequently Asked Questions

We recommend replacing your air conditioning system every 8-15 years. However, this depends on a lot of different variables – if your air conditioning unit is properly installed and maintained, it could serve you for even longer. It also depends on what type of system you have and the particular make and model. All of that said, we can’t emphasize enough how proper maintenance can help your air conditioning system to run for years to come.

Please ensure that the path is clear from the entry of your home to where the air conditioning unit will be installed. It’s also a good idea to ensure that the furnace room is accessible, as well as the area outside your home where the unit will be. The best ways to prepare depend on your home and what type of unit is being installed, so you should ask about this during your in-home assessment.

A proper air conditioning installation should never be rushed. We generally are able to install a new unit in 4 to 6 hours, but this depends on things like whether the installation areas are accessible or if there is an old unit that needs to be uninstalled. We also factor in what kind of system we are installing.

While it’s not totally necessary for you to be home during the installation, we do recommend it. That way, you can let us in upon arrival, and at the end of the installation, we can show you how to properly operate your new system. The technician who just installed your new unit is usually best equipped to answer any questions or concerns you may have.

How long it takes and how much it costs to complete the work that you’ve requested depends almost entirely on what work that is. If you are purchasing only a small accessory package, this will not take as long or cost as much as a larger one, which could include things like ventilation and ductwork.
