"I called 5 different electricians and no one would call me back. I'm assuming that is because my house is 124 years old. I was given their business card from an employee at Lowes in Warsaw. They came out and connected all three circuits that I had already installed into the circuit breaker box. They were very professional, efficient, and knowledgeable. They did a very good job and picked up all the trash. They offered to come back and do other electrical work for me. I strongly recommend this company that is willing to actually do work. They were extremely reasonable price wise. I was charged $150.00 to connect all three circuits to the circuit breaker box. Quite a Blessing!!"

Heating Oil questions, answered by experts

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.
