If you have lived in Mentor for a while, you already know how quickly the weather can change here. One week the wind is rolling off Lake Erie near Headlands Beach, and the next week humidity is hanging over neighborhoods near Hopkins Road and Bellflower Road. Kobella Heating & Cooling stays busy throughout the 44060 area because homes across Mentor are now reaching the age where furnaces, AC systems, sump pumps, and water heaters all start needing attention at the same time.
From older ranch homes off Mentor Avenue to newer developments near Heisley Road and Route 615, our technicians help local homeowners keep their systems running reliably year-round. If your heating, cooling, or plumbing system has started giving you trouble, call (440) 363-6803 or contact Kobella Heating & Cooling online to schedule service in Mentor.
The Types of Homes We Work on Throughout Mentor
Much of the housing throughout Mentor was built during the city’s biggest growth years around Center Street, Johnnycake Ridge Road, and the neighborhoods surrounding Mentor High School. We regularly work in split-level homes, ranches, and colonials where original furnaces, ductwork, and plumbing systems are starting to show their age.
Homes closer to Mentor Harbor and the Lake Erie shoreline often deal with more moisture and winter wind exposure, while newer areas near Route 84 tend to have larger layouts with finished basements and added HVAC demand. Because Kobella services homes throughout Mentor every week, our technicians know the kinds of comfort, airflow, and plumbing problems that commonly show up in different parts of the city.
Air Conditioning & Cooling in Mentor, OH
When the humidity settles into Mentor during July and August, a struggling AC system becomes noticeable fast. We get a lot of calls from homeowners near Reynolds Road, Lakeshore Boulevard, and neighborhoods around Garfield Park where the system runs constantly but certain rooms still feel warm and sticky by the afternoon. Kobella Heating & Cooling provides:

Heating Repair & Furnace Replacement in Mentor, OH
Mentor winters can be rough on heating equipment, especially during stretches where lake effect snow and freezing wind push systems nonstop for days at a time. Around neighborhoods near Mentor-on-the-Lake and the shoreline, we often see furnaces working harder simply because of colder drafts and older insulation. Heating solutions available throughout Mentor include:
- Heating Repair
- Heating Installation
- Heating Maintenance
- Furnaces
- Boilers
- Heat Pumps
- Heat Pump Repair
- Heat Pump Replacement
- Heat Pump Installation

Homes throughout Mentor still commonly operate with older duct layouts that create uneven heating from room to room, especially in homes near Center Street and Mentor Avenue. In many cases, the issue comes down to airflow restrictions, aging components, or ductwork problems rather than the furnace itself.
We also continue servicing older boiler and radiant heating systems throughout Mentor that many companies no longer work on regularly.
Plumbing Repair & Water Heater Services in Mentor, OH
Plumbing problems in Mentor usually start small. A kitchen drain starts slowing down near a house off Tyler Boulevard. A sump pump cycles constantly after a storm near the lagoons. A water heater in a basement off Hoose Road begins leaking around the bottom seam. Our plumbing services include:

- Kitchen Plumbing
- Water Heaters
- Water Treatment
- Sewer & Drain

Older plumbing systems throughout Mentor are starting to show their age, especially in homes with aging drain lines, older shutoff valves, and original piping. We also regularly see tree root intrusion in older neighborhoods and sump pump problems after heavy Lake County storms.
Hard water buildup can also wear down fixtures and water heaters over time, especially in homes where the plumbing system has not been updated in years.
Indoor Air Quality Solutions for Mentor Homes
Homeowners throughout Mentor often notice comfort problems that are not really temperature problems at all. Homes near Mentor Harbor and Lakeshore Boulevard frequently deal with damp air and excess humidity during summer, while older homes around Center Street and the Mentor Avenue corridor often feel overly dry once the furnace starts running through winter. Kobella Heating & Cooling installs and services:
- Humidifiers & Dehumidifiers
- Air Scrubbers & Purifiers
We spend a lot of time helping homeowners improve the overall feel of the house, especially in homes with finished basements, older duct systems, or pets. Better humidity control and air filtration can make a major difference in how comfortable your home feels day to day.

Responded to multiple clogged drains and toilet backups on a slab-foundation home with moisture detected along the bedroom/bathroom shared wall. Snaked the affected fixture drains and cleared the blockage, restoring proper flow and eliminating the backups, and inspected the sewer cleanout and drain line using a camera inspection unit to locate the obstruction and confirm line condition. Recommended further moisture mitigation of the damp carpet and wall area, with follow-up evaluation of the slab drain line if dampness persists.
Performed a replacement estimate on a 1987 Weil-McLain boiler with a recurring mercury switch sticking issue, as the homeowner is evaluating whether to keep the unit operating another year. Inspected the open burner compartment, gas controls, wiring, Extrol expansion tank, copper supply/return piping, pressure relief valve, and galvanized flue, and documented typical age-related wear, surface darkening, and dust accumulation with no obvious breakage or leaks. Reviewed repair-versus-replacement options based on the system's age and condition.
Responded to a no-heat call on a 1987 gas-fired boiler with a recurring mercury switch sticking issue and inspected the control compartment, gas control valve, and burner assembly. Found dirty, discolored terminal connections on the gas valve and soot accumulation on the burner tubes, with crumbling refractory material at the appliance base. System was evaluated for continued operation given its age, as the owner is attempting to keep it running another year.
Performed scheduled heating maintenance, including inspection of the integrated furnace control board, low-voltage wiring, and splice connections, and visual inspection of the blower assembly. Noted accumulated dust and debris on the blower wheel blades and dense, tangled wiring with taped wire-nut splices in the control cabinet, which may warrant further evaluation or cleaning to maintain airflow and reliable system operation.
Performed seasonal heating maintenance and measured system differential pressure with a dual port manometer to verify proper airflow and static pressure. Inspected the AprilAire humidifier water panel (evaporator pad) and found heavy mineral buildup and discoloration, indicating it was due for replacement.
Performed a rebuild of the Wilkins 950XL reduced pressure principle backflow preventer assembly, including inspection of the pressure-reducing valve, test cocks, and shutoff valves, and replacement of internal wear components as needed. Restored the assembly to proper operating condition and verified correct differential pressure and check valve function after reassembly.
Responded to a complaint of a high-pitched noise at furnace startup lasting a short duration. Inspected the air handler cabinet and began diagnostics with the draft inducer motor, measuring motor amperage with a true RMS clamp meter (reading 3.92 A) to evaluate motor and bearing condition. Verified cabinet seams and sealant, as well as refrigerant line and pipe penetrations at the cabinet base, to rule out air leakage or vibration as the source of the noise.
Performed a seasonal heating maintenance visit on a Trane gas furnace, replacing the pleated return air filter and labeling it with the service date for future reference. Inspected the furnace cabinet, wiring harness, PVC vent and condensate piping, and adjacent Aprilaire unit, finding no signs of frost, rust, or damage, and left the system operating normally with the service tag attached.
Performed an on-site assessment for a boiler replacement, inspecting the existing gas-fired boiler, draft hood and vent connection, expansion tank, pressure regulator, supply and return piping, and adjacent water heater. Documented significant soot staining, scorching, and discoloration on the boiler's exterior and vent components, along with sediment and water staining on the surrounding floor, indicating combustion and moisture concerns. Photographed all equipment and conditions to support replacement scoping and recommendations.
Performed an on-site evaluation for HVAC system replacement of a closet-installed furnace/air handler with galvanized flue and ductwork, adjacent to a gas-fired water heater. Documented significant staining, mineral deposits, and moisture damage around the PVC condensate drain line and surrounding floor and door trim, indicating prior leakage or a condensate drainage deficiency. Replacement scope should include correcting condensate drainage and verifying flue, ductwork, and gas line connections.
Performed a seasonal tune-up and safety inspection on one Goodman gas furnace and one air conditioning system at the customer's request. Inspected the furnace, flame sensor, and venting, and reviewed the club maintenance membership options with the customer.
Installed an Amana AMVT variable-speed air handler (2-ton, 15 SEER heat pump system) in the basement utility area, with galvanized supply plenum and transitions connected to the existing ductwork and PVC condensate drain piping with isolation valves routed to the floor drain. Verified static pressure with a dual-port manometer (0.26 IWC supply / -0.30 IWC return) to confirm airflow is within acceptable operating range.
Performed scheduled preventive maintenance on the HVAC system and whole-house humidifier under the prepaid maintenance plan. Inspected the humidifier and found heavy mineral scale buildup on the evaporator pad, indicating the pad is due for cleaning or replacement. Verified electrical operation with a true-RMS clamp meter, measuring AC voltage at the unit to confirm proper supply.
Performed a diagnostic evaluation of the gas furnace and air handler, identifying a cracked heat exchanger and a failed inducer motor, and determined that a full system replacement is warranted. Also investigated a reported rattling noise during operation and assessed the unit's overall condition, including the condensate drain line and pump, electrical connections, and surrounding installation, with no frost, rust, or major damage observed. A replacement estimate was prepared and presented for review.
Performed a tune-up on the furnace in response to a reported rattling noise during operation, inspecting the cabinet interior, wiring connections, and vent/flue tubing for loose or worn components. Conducted a combustion analysis with a Testo 310 analyzer, which recorded 7.4% O2 and 100 ppm CO, indicating CO levels at the upper limit of acceptable range and warranting further burner and heat exchanger evaluation. Interior of the cabinet showed dust accumulation and minor surface corrosion near the seam, which should be monitored.
Performed a scheduled heating-season maintenance visit for a maintenance club member, accessing the equipment via the rear entrance. Conducted electrical diagnostics on the system using a True RMS clamp meter, verifying amperage draw (approximately 0.30 A measured) and voltage readings to confirm proper component operation. No visible damage, frost, or corrosion was observed, and the system was left operating normally.
Returned to the site to replace the combustion (draft inducer) motor on the furnace, which showed soot discoloration and heat damage at the housing. Removed the failed inducer assembly, installed the new motor with the flue collar and wiring connections secured, then verified proper voltage at the motor with a multimeter and confirmed correct operation.
Installed a Daikin Aurora cold-climate 15K heat pump mini split system with a drain pan heater, equipment stand/pad, concealed exterior line set with proper condensate drainage, and Bolder thermostats. Leveled and secured the outdoor unit and electrical disconnect, then evacuated the refrigerant lines with a digital micron gauge to verify a deep, leak-free vacuum before releasing refrigerant. Also performed complimentary maintenance on the existing furnace and AC system.
Performed annual heating maintenance, inspecting the furnace interior, inducer motor assembly, flame sensor/igniter, wiring, and vent hoses. Conducted combustion analysis on natural gas, with results within normal operating range: CO 13 ppm, O2 8.5%, CO2 7.01%, and efficiency 94.8%. Noted heavy rust and corrosion on the cabinet base and brackets, which should be monitored and addressed to prevent further deterioration.
Conducted diagnostic site visit to assess air handler installation and replacement feasibility. Documented existing unit dimensions and clearances, measuring 202" height with various clearance specifications noted throughout mechanical room. Identified installation challenge with ceiling grid support wires interfering with refrigerant lineset routing where acoustic tile ceiling meets drywall transition. Photographed obstruction points and documented spatial constraints for future equipment replacement planning.
