"The technician did a great job when he came out to look at the unit. He fixed one and found a leak in the other one. I needed a quote for my home insurance company. Turns our Aire Serve Pro is in collaboration with the home warranty company to get as much of the repair as possible to not be covered by my home warranty. They would not give me a normal quote of time and materials. They would only give me a quote where all the costs are wrapped into a per pound of refrigerant cost. This drastically increases the cost per pound of refrigerant by 10x. You can literally buy 410a refrigerant for $10 per pound (see attached) but they wanted to charge $151 per pound with all the costs rolled in. The insurance company then says....we only pay the market rate of $10/pound for refrigerant and I have to pay the difference. Which means the insurance company only covers 10% of the repair. The woman said because I went thru insurance they had to do it this way and could give me a time/material quot"

Since 1984, Cardinal Heating, Cooling, Plumbing & Electric has provided the Sun Prairie, WI and the surrounding area with exceptional Heating, Air Conditioning, Electrical and Plumbing services. We offer professional technicians, same-day installations and 24-hour emergency service. We believe we are the right choice for any of your HVAC, Plumbing, or Electrical needs. Call today to schedule your next appointment!

"Had an old fixture above kitchen sink go kaput (fluorescent starter disintegrated), so Cardinal came out and offered LED alternatives (two provided, brought on-hand from supply warehouse). Also fixed a switched outlet that had shorted out. Great work done, nice alternatives for the LED light, and switched outlet was wired to be always-on for one socket and switched for the other -- better than it was before at no additional cost. Later I called to ask the exact serial and model number of the LED light because the papers left did not state it. Not only did I get an email a couple hours later with the model/serial, the tech included the detailed documentation for the fixture so if anything goes wrong I can likely fix it myself next time. The tech who did the work also applied a 10% off discount card for me with no extra hassle, saving me close to $100 on the work."

"Great to work with. They were efficient and knowledgeable. They took care of the rebate for our heat pump. Only thing lacking was responsiveness to email/phone communication after the install was done. Heat pump system is working great."

Hi every body, this is Oscar and I know the quality of work I can do for you. I have maintenance experience from different companies. My work is about painting, some flooring, drywall repairs, appliances troubleshooting, gutters and roof cleaning, downspout, dryer vent cleaning and general cleaning services at home. Anything I can help let me know. I speak English, Spanish, and Italian if it’s needed.

"Top marks all the way around for Oscar. Oscar is the best handyman we’ve ever employed. He was everything you want in someone working on your home: excellent communication, reasonable cost, high quality work, prompt, dependable, friendly, neat, cleans up after each day of work, very detail-oriented, and just a really nice guy. He re-screened our 3-season porch, replaced all the exterior wood facings on the porch, hung a new and much improved door on same porch, replaced about 12 feet of cedar privacy fence, and power washed the full exterior of our house. There is no question that we will call Oscar again when we need work done. If you’re looking for a talented handyman, look no further; just call Oscar. "

Heating Oil questions, answered by experts

You can expect a geothermal system to last for years. According to the Department of Energy, the underground infrastructure for the heat pumps lasts about 25 to 50 years, which includes the pipes buried in the soil. The actual heat pump itself has a life span of around 25 years.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

Costs depend on system age, type, labor, and whether part replacements are necessary.

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.
