Excellent !

Crew was very efficient and knowledgeable. Replaced HVAC with next day service for first responders. System is working well and installed superbly. Will give it a run for a while to better judge but it is a quality name Lennox system. 10 year parts and service so expect there will be no problems. Good job!

Above & Beyond

Technician Steve, was very thorough in his investigation. Went above what I asked for, we had a black water flood and I was just asking to have the toilet and sink reinstalled. He put his camera through my sewer system to make sure that we were not going to have future issues. He made sure that I was able to see what he saw. It was educational to say the least and he was great at explaining what was in there. Feel very safe using his services and do not feel that he is taking advantage in any way. Highly recommend Steve!!

Very Professional

It was really shocking the amount of damage our pipes had and mr Johnson helped to explain what the issue was... He worked within our budget and created a couple of quotes with positive solutions. We went with the one we felt was necessary and he worked quickly getting that issue resolved. Very professional and knowledgeable.

Knowledgeable

I had Mainstream come out for an annual inspection of my hot water heater. After the inspection, it was determined that the water heater needs to be replaced. The technician, Cory, was very professional and made all of the necessary arrangements. Later the same day, Shane came out and replaced the water heater. Shane was very professional and knowledgeable. I am very pleased with the employees and the work that was completed by Mainstream.

Very Happy

We had them come out for a yearly maintenance on our water heater. They were thorough and gave good recommendations for continued maintenance and use. We also had them install a new furnace and air conditioning unit. They were very quick and efficient. All the crew members were courteous and respectful of our home. I am very happy to recommend them to others.

How Much Does a Central Air Conditioning Unit Installation Cost?

The cost of a new air conditioning system installation can vary widely. Several factors affect the price to install a new A/C system:

What's a Pre-Installation Evaluation? Does My New A/C Need One?

In short, yes. A first step is conducting an energy audit to determine the energy load for your home. Calculating the load tells the experts at Mainstream Electric, Heating, Cooling, & Plumbing how much heat your house gains throughout the day & what size air conditioner will work best to keep it cool. This is critical as most A/C installation issues stem from an improperly-sized air conditioning unit.

Is Your Home's Ductwork & Design Able to Handle a New A/C System?

Often your old, existing ducts can't handle the airflow of a newly installed air conditioner. Any upgrades to accommodate a new system will likely increase the cost to install an A/C unit, but will ultimately help you avoid costly, high energy bills & hot rooms in the future.

What Type of Central A/C Unit Should I Install?

Here's where the load calculation comes into play, as you want to pick the right size A/C unit to install - either too big or too small of an A/C unit can lead to costly repair or replacement down the road. Call the HVAC professionals at Mainstream Electric, Heating, Cooling, & Plumbing, they'll know which A/C unit is perfect to install in your home at the lowest price.

No matter the problem, our A/C installation technicians will determine your A/C needs & finances before any work is done, so you will know exactly what solution is best & most affordable for your new air conditioning system.

The summer heat in Spokane Valley is nothing to scoff at! Whether you live in Hayden, Airway Miles, Coeur d’Alene, or anywhere else in the area, Mainstream Electric, Heating, Cooling, & Plumbing will come to you and install a new A/C system for your home.
