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:
- AC Repair
- AC Installation
- AC Maintenance

Cooling problems in Mentor often show up in homes that were expanded over the years without updating the original AC system. We regularly help homeowners near the Great Lakes Mall area solve uneven cooling, airflow, and humidity problems caused by undersized ductwork or older system layouts.
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:
- Plumbing Repair
- Bathroom Plumbing
- 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.

Job Locations and Reviews
Performed annual heating maintenance on the furnace, including electrical testing of the system with a digital clamp multimeter and a combustion analysis using a Testo 310 analyzer, which recorded O2 at 6.0% and CO2 at 8.35%. Identified the system's air filter size as 14x25x1 and confirmed the unit was operating within normal parameters.
Conducted a site assessment for a ductless mini-split installation, evaluating a bedroom location for a 6K BTU indoor air handler and a basement room for a 9K BTU unit, with outdoor unit (ODU) placement to be determined. Identified existing baseboard heating and exposed overhead joists at both locations, and noted that a core drill will be required to penetrate the wall for the refrigerant line set and condensate routing.
Performed scheduled preventive maintenance on the HVAC system, including a temperature measurement with a calibrated digital multimeter and thermocouple probe (66.8° reading recorded). Inspected the pleated air filter, which showed light dust loading with uneven pleats and slight fraying along the edge, and renewed the filter to restore proper airflow and system efficiency.
Performed scheduled preventive maintenance on the HVAC system, including electrical diagnostics with a True RMS clamp meter, which measured 54.3 Ω resistance on the tested component. Conducted combustion analysis with a testo 310 analyzer, recording 8.5% O₂ and 97.3% efficiency, confirming the unit is operating within normal combustion parameters. No visible damage, frost, rust, or cracking was observed.
Performed scheduled preventive maintenance on the air handler and furnace, including inspection of the pleated return air filter and cabinet, which showed no visible damage, rust, or frost. Conducted a combustion analysis through the test port, recording Oâ‚‚ at 8.5% and CO at 6 ppm, confirming safe, within-range combustion, and resealed the test port cover upon completion.
Performed a maintenance inspection on the newly installed furnace and air conditioning system and checked the return air plenum and filter assembly. The existing 20x25x1 pleated filter was heavily loaded with dust and debris, with some creased pleats, and was removed and replaced with a clean filter to restore proper airflow and protect the system components. The plenum interior was found clean with no visible issues.
Responded to a sewer gas odor complaint in the bathroom; inspection of the closet flange revealed a deteriorated, displaced wax ring with staining and corrosion visible in the drain, allowing sewer gas to escape. Removed the toilet, cleared the old wax seal from the flange, and verified the closet bolts and flange condition. Reset the toilet on a new wax ring, confirmed it was level and secure, and verified the odor was eliminated.
Performed an on-site estimate for replacement of a 40-gallon gas storage tank water heater, inspecting the existing unit, its copper supply piping, shutoff valve, and PVC venting/drain connections in the utility space. Documented the installation with photos, noting heavy dust and cobweb accumulation, stained and discolored PVC piping with crusty residue at the fitting joint, and an aged unit of unknown vintage. Findings were reviewed to determine the scope for a like-for-like standard tank replacement.
Responded to a no-heat call on a basement furnace and inspected the integrated furnace control board and hot surface ignitor circuit. Photographed and documented the control board, relay, and wiring connections to verify the ignition failure. Findings are consistent with a non-functioning ignitor preventing ignition, which caused the loss of heat.
Performed seasonal heating maintenance inspection on the furnace, including visual inspection of the gas supply line, venting and flue ductwork, condensate/PVC piping, and associated wiring and controls, with no signs of corrosion, leaks, or damage observed. Verified thermostat operation on the Honeywell Home ProSeries unit, confirming proper call for heat with the setpoint at 70°F and the system functioning normally.
Enrolled the system in the maintenance club and performed a preventative maintenance inspection. Found the return air filter heavily loaded with dust and debris, restricting airflow, and documented its condition for replacement. Inspected the control board and wiring connections and found no signs of damage, corrosion, or burn marks, with the board and terminal connections in good condition.
Performed a heating tune-up on the gas furnace, including inspection of major components and verification of electrical operation with a clamp meter (blower motor amp draw measured at 1.87 A). Conducted a combustion analysis, recording Oâ‚‚ at 8.0% and COâ‚‚ at 7.23%, to confirm safe, efficient burner operation. Located and identified the air filter for the homeowner, and the system was left operational and ready for the heating season.
Performed an on-site replacement estimate for a 30-year-old upright gas furnace in a utility closet, inspecting the unit, flexible vent connection, gas supply piping, and electrical disconnect. Documented existing conditions with photos and evaluated replacement options for both a furnace-only changeout and a full system replacement.
Responded to emergency no-heat call on a residential gas condensing furnace and inspected the unit, including the control board enclosure, condensate drain piping, and condensate pump. Found moisture and condensation residue within the control board cover, indicating a condensate drainage issue affecting furnace operation. Verified gas supply and safety controls, addressed the condensate/drain concern, and returned the system to normal heating operation.
Performed annual maintenance tune-up on the gas furnace, including inspection of the control compartment, circuit board, wiring harness connections, and transformer, with no visible corrosion, loose connections, or damage noted. Conducted combustion analysis using a Testo analyzer, recording Oâ‚‚ at 7.7% and COâ‚‚ at 7.40% to verify proper burner operation and combustion efficiency.
Conducted an on-site evaluation for a whole-home ductless mini split system in a residence heated by a gas boiler with a hydronic air handler. Inspected the mechanical room, noting the boiler, gas-fired water heater, and flue and piping layout, and assessed the attic as a potential location for indoor air handlers, line set routing, and condensate drainage. Both areas are cluttered with stored items, so access will need to be cleared before installation, and the findings will be used to size a multi-zone system and plan equipment placement.
Performed routine heating maintenance and tune-up on a 19-year-old American Standard system, including filter replacement and inspection of key components. Used a True RMS clamp meter to measure amperage draw on the system's electrical components during operation (readings of approximately 0.78 A and 2.83 A) to verify motor and component performance.
