FAQ
What is the average life expectancy of equipment?
Most systems have a lifetime of 10 to 20 years. As your equipment gets older, its efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show it’s age, you have two choices. You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new system designed with newer, more energy-efficient equipment makes sense, especially if your system is 10 or more years old. We can estimate the cost of a new system as well as a payback schedule that will show you how newer technology will pay you back in lower energy usage.
Why should I purchase a service agreement?
Without warranty coverage, a breakdown can mean significant expense in parts, labor, or both. However, with one of our service agreements, you avoid that unexpected significant expense. While no warranty can guard against every possible problem, we can explain the broad range of protection our service agreements afford.
Why should I buy Energy Star labeled equipment?
The average home spends about $1,900 annually on energy bills. Heating and cooling accounts for as much as half of a home’s energy use. The EPA provides important recommendations for energy-efficient equipment, including proper sizing, quality installation and maintenance, and other home improvement considerations to help you get the most out of the heating and cooling products you purchase, save energy, and save as much as 20% annually on your total energy costs.
ENERGY STAR qualified products prevent greenhouse gas emissions by meeting strict energy efficiency guidelines set by the U.S. Environmental Protection Agency and the U.S. Department of Energy.
What does the Energy Factor (EF) on my water heater mean?
The water heater Energy Factor is a measure of the overall efficiency of the water heater. This is determined by comparing the energy in the heated water used daily to the total daily energy consumption of the water heater. The EF can be used to compare the energy efficiency of water heaters. Water heaters with higher EFs will have lower annual operating costs than comparable models with lower EFs. A higher EF signifies a more efficient model. Water heaters with high EF ratings may cost more initially, but save energy and money in the long run. Eventually, they will pay for themselves through a lifetime of energy savings.

Job Locations and Reviews
Performed routine monthly maintenance on the heating system, replacing the return air filter and documenting the filter size as 16x20x1. Verified thermostat operation in heat mode with fan set to auto; the system responded normally, with the indoor temperature at 72° against a 68° setpoint.
Responded to callback for a carbon monoxide detector alarming within one week of the original service. Inspected the gas supply connection at the appliance, including the flexible gas line, shutoff valve, and fittings, and checked the surrounding area for leaks, residue, or other signs of combustion or gas-related issues. Verified the CO device readings and confirmed the system was operating safely at completion.
Performed a heating system maintenance visit under an expired-but-owed service plan, inspecting the wall-mounted digital thermostat (reading 69°F) and the air handler/ductwork in the utility closet. A 20x20x4 MERV 11 pleated filter was on site for the system but was not included in the scope of the visit, and the filter's airflow arrow should be matched to the air handler's direction when it is installed.
Performed an on-site evaluation for replacing an aging furnace with a heat pump system at a manufactured home, including assessment of the existing outdoor condenser, electrical disconnect, and exterior equipment placement. Documented the existing condenser, which showed dirty coil surfaces with mineral buildup, along with surrounding site conditions, to determine installation requirements and equipment sizing for the heat pump conversion.
Performed scheduled seasonal heating maintenance on a Lennox ML196DFE downflow gas furnace under the Comfort Club plan. Inspected the burner assembly, gas valve, draft inducer, pressure switch, and flue connections with the access panel removed, and found no evidence of cracking, rust, or frost, though light dust and soiling were present. Replaced the 20x20x4 return air filter, verified the equipment documentation and maintenance history were up to date, and recorded the visit.
Performed seasonal heating system maintenance, including inspection of the air handler interior and insulation liner and a supply-side temperature reading of 127.2°F at the plenum to verify heating output. Confirmed the system is operating properly and noted a 16x20x1 filter size for future replacement. The customer's maintenance plan is active through 12/2026, with renewal recommended.
Responded to a non-functioning Carrier touchscreen thermostat and found the system event log recording simultaneous high and low pressure switch open faults on the heat pump. Inspected the outdoor condenser unit and its disconnect, and documented the thermostat fault history and unit data for manufacturer warranty verification. Further diagnosis of the refrigerant circuit and pressure switch operation is recommended, and the thermostat is to be evaluated for warranty replacement.
Performed monthly preventative maintenance on the water-source heat pump in heating mode, including inspection of the unit, ductwork, plenum, and thermostat controls. Inspected the GEOLINK circulator pump, loop piping, flexible hoses, and isolation valves, and noted heavy rust on the pump flange along with floor staining and moisture near the pipe connections that should be monitored for leaks. Filter replacement was not included in this visit (20x25x4 filter size).
Responded to a no-operation call on the outdoor condensing unit. Inspected the condenser cabinet, fan assembly, and coil guard, which were intact with no ice, rust, or physical damage, and checked the Lennox thermostat, which showed the system in the off position with indoor temperature at 80°. Verified the call for cooling and system operation at the thermostat and outdoor unit.
Responded to an emergency no-water call caused by damaged water softener supply lines and isolated the affected section of the system. Replaced the broken connections with new flexible PEX tubing and brass crimp fittings, secured with clamps, then reopened the shutoff valves to restore water service. Verified the repair was leak-free and confirmed normal flow and pressure throughout the home.
Assessed the existing tank-style water heater and its atmospheric flue venting in the basement mechanical area for conversion to a tankless unit. Evaluated available wall space, clearances, and the proximity of existing HVAC ductwork, supply piping, and electrical for proper installation, noting that venting, gas supply sizing, and combustion air requirements will need to be addressed. Documented the site conditions with photos to support the estimate for removal of the current unit and installation of the new tankless system.
Performed scheduled heating maintenance, replacing the 16x25x1 pleated air filter to restore proper airflow and system efficiency. Verified thermostat operation in heat mode, confirming the unit was calling for heat with the display reading 74°F and no visible damage or abnormalities.
Inspected the existing electrical supply and wiring serving the garage bathroom to verify continuity and power availability for a proposed small heater for freeze protection of the plumbing. Evaluated the existing heater's thermostat/control components and wiring connections, which showed accumulated debris and aged parts, to determine whether the current conductors can be reused or if new wire must be run. Findings will be used to prepare an estimate for the rewire or heater installation.
Responded to a no-cooling complaint and performed a full A/C system diagnostic, inspecting the vertical air handler, refrigerant line set, low-voltage and line-voltage wiring connections, and thermostat operation. Observed the thermostat calling for cooling (set to Cool, reading 79°) and noted deteriorated refrigerant line insulation and loose, unprotected wiring at the air handler, which are potential contributors to reduced cooling performance. Verified system operation following service and recommended replacing the worn suction line insulation and properly securing the electrical connections to prevent future issues.
Replaced the failed main water line shut-off valve in the crawl space, which was leaking at the tee fitting and showing heavy corrosion on the surrounding copper.
