 Trustindex verifies that the original source of the review is Google. We reached out to Pharo when we decided to finish our unfinished basement. Pharo had done the HVAC work for the rest of our home so we reached out to them to add the additional duct work required. They came out quickly, gave us a quote that was really reasonable and were extremely thorough in their installation. The quality of their work really speaks for itself. Would recommend to anyone looking for HVAC work!

 Trustindex verifies that the original source of the review is Google. We came home yesterday about noon to find our furnace not working. We called Pharo and a service technician was at our door within a hour. The tech replaced a faulty part and we're up and running. I highly recommend Pharo Heating & Cooling.

 Trustindex verifies that the original source of the review is Google. Furnace went out overnight a few times. Called when Pharo opened at 7:30 and someone was at our house by 8:30. Serviceman was knowledgeable, friendly, and efficient. He was able to solve the problem quickly. Very happy with the service we received!

Frequently Asked Questions

How do I know what size heating system I need?

Proper sizing depends on your home’s square footage, insulation, layout, and heating demands during Wisconsin winters. Our team evaluates these factors before recommending equipment so your new system is matched correctly to your home.

How long does heating system replacement take?

Most replacements are completed in one day. Timing depends on the project scope, equipment type, and whether any ductwork or venting changes are needed.

Will a new heating system lower my energy bills?

A high-efficiency furnace or boiler can reduce wasted energy and may lower your monthly heating costs compared with an older, less efficient system.

Should I repair or replace my old furnace or boiler?

If your system is older, needs frequent repairs, or can’t keep your home warm, replacement often offers better long-term value than continuing to invest in aging equipment.

Yes. We handle removal of your old furnace or boiler and manage the full replacement process from start to finish.

Do you offer financing for heating system replacement?

Yes. We offer financing options to help make a new heating system more affordable. Ask our team for current details.
