Plainfield Specifics

Why Plainfield Homes Need Extra Attention

Plainfield's Lake Michigan water, which the Village lists at 6.3 grains per gallon, is enough to clog condensate drain lines, so we flush them on every maintenance call before one backs up into the air handler. Local silt loam soil pools water around foundations, and poorly drained homes in 60585 and 60544 run their AC longer and harder, which we factor into sizing. The technician from our shop on Rhea Drive does the work. We don't subcontract.

What Plainfield Homeowners Ask Us

My AC is running but the house won't cool down. What's causing it?
Low refrigerant from a slow leak, a dirty evaporator coil, a failing compressor, undersized ducts or the thermostat. We start with an electrical and refrigerant check and work outward from the air handler, usually finding the cause in one visit.
How often should AC equipment be serviced in the Plainfield area?
Once a year, ideally in April or early May, before Plainfield summers push systems hard from June through August. A spring tune-up catches refrigerant loss, dirty coils and worn electrical parts while there is time to order parts.
Does Plainfield require a permit for AC replacement?
Yes. The Village of Plainfield Building Department requires a permit for new HVAC installations and equipment replacements, inspected against the 2021 International Mechanical Code. We handle the paperwork. A contractor who says a straight replacement needs no permit here is wrong, and unpermitted work causes problems at resale.
How do I know if I should repair or replace my AC system?
Under ten years old with one clear fault, fix it. Over fifteen years, failing often, running inefficiently or using R-22 refrigerant, replacement is generally better because repair costs stack against its remaining life. We give you a straight read after the diagnostic.

Written on behalf of my mom Annie: I am very satisfied with Chris Leto's service. He addressed the issue quickly and professionally. Charged a fair price.

In February of 2026 I used Leto Plumbing & Heating on two occasions. First for an emergency after hours weekend call when my sump pump line was frozen during our recent sub-zero weather. The second was a routine maintenance call to flush my hot water heaters. Both times the individuals that came out were pros who were friendly, knowledgeable and got the job done right the first time. Would highly recommend!

Leto Plumbing has been servicing the plumbing and HVAC in our homes for many years. Rick and Chris, father and son, are amazing in every way. They are reliable, neat, courteous, and knowledgeable in all areas of plumbing and HVAC. They go out of their way to rush out to our home for needed repairs and new work. They may not be “cheap”, but you can rest easy that their work is top quality and will give you peace of mind. TFK St. Charles

Very happy with the service received by Leto plumbing. Starting with phone call made, very nice and was able to get us scheduled next day. Chris, technician, was earlier than originally expected (which was great), he explained everything, was very courteous and timely. Extremely happy with service provided and will be calling Leto for any future needs.
