What we do
Heating & cooling repairs, replacements, and more
Mostly residential, with light commercial welcome. Customers describe the same job in different ways — a “replacement” to one homeowner is a “new install” to another — so if you are not sure which service you need, call and describe what is going on.
Replacements & New Installations
Replacing an existing system or installing a new one — sized for your space, not just swapped in. Free on-site estimates. See what is changing for furnaces.
Maintenance
Routine service for existing equipment to help extend its life, keep efficiency up, and catch problems before the mid-season breakdown.
Ductless Systems
Ductless mini-split installation, replacement, repair, and maintenance — for homes without ductwork, additions, or rooms the central system can’t keep comfortable. Read ductless vs. central HVAC.
Indoor Air Quality
Filtration, ventilation, humidity control, and IAQ monitoring — because comfort means clean, healthy air.
Light Commercial
Service, replacement, and installation for light commercial spaces, property managers, and building contractors — coordinated, reliable, and code-compliant.
Sales & Equipment
Access to a wide network of manufacturers and vendors — the right equipment for the job, with no single-brand bias.
How pricing works
Estimates, diagnostics & what to expect
The first question most people ask is “How much?” — and that’s normal. Every job is different, so we need to see the job to price it accurately.
Free estimates for new systems & replacements
Pricing a new system or replacement means evaluating the space and the existing setup — measurements and a conversation about what you need. There is no charge for this estimate.
Diagnostic fee for system problems
When a system isn’t working right, troubleshooting means putting tools to work to find the cause. That diagnostic visit has a fee — and the entire fee is applied toward the repair.
Financing for larger jobs
Financing is available for bigger projects, including emergency system replacements. Call to discuss the options available for your job.
Warranty on installations & replacements
A labor warranty is standard with every system replacement and new installation. Manufacturer equipment warranties come with their own terms, and we help you with registration.
Why licensed contractors price the way they do: a licensed and insured contractor carries licensing, insurance, training, tools, and vehicles so the work is done to code and you are protected if something goes wrong. That is part of what you are paying for.
Indoor air quality
IAQ products we install & service
Clean air is half of comfort. These whole-home systems integrate with your HVAC equipment to filter, ventilate, and balance humidity — far beyond what a standard 1-inch filter can do. We specify, install, and service them all, with no single-brand bias.
Media air cleaners
High-MERV (MERV 13–16) media filtration built into your ductwork — captures dust, pollen, pet dander, and fine particles with minimal airflow loss.
UV-C germicidal lights
Ultraviolet light in the airstream and at the coil to reduce bacteria, viruses, and mold — and keep the evaporator coil clean for better efficiency.
Whole-home humidifiers
Bypass, fan-powered, and steam humidifiers that hold a healthy 30–50% relative humidity in winter — protecting sinuses, woodwork, and electronics.
Whole-home dehumidifiers
Tackle damp basements and humid summers, cut mold and dust-mite growth, and let you set the thermostat a few degrees higher while staying comfortable.
Ventilation (ERV / HRV)
Energy and heat recovery ventilators bring in fresh, filtered outdoor air and exhaust stale air while recovering the heating or cooling you already paid for.
Air purifiers & VOC control
Whole-home purifiers with carbon and photocatalytic stages that neutralize odors, smoke, and volatile organic compounds from cooking, cleaning, and furnishings.

Who owns which brand?
The HVAC industry has consolidated into a handful of global parent companies, so several “competing” labels are built by the same company. Our brand guide shows the family tree so you can compare value, not logos.

HVAC Week in Review: November 4 - 10, 2026
November price increases of 3 to 15% on parts and materials, distributor sales up 9%, the midterms shift refrigerant and incentive battles to the states, dual-fuel thermostats get smarter, data center cooling demand hits records, and France blames Iran for the refrigeration hacks.
Tools
Refrigerant Charging by Superheat, Subcooling, and Weight: The Tools, the Targets, and How Often Charge Is Wrong
Field studies of more than 4,000 air conditioners found about 72% charged outside manufacturer tolerances. ENERGY STAR quality installation calls for subcooling within 3°F or superheat within 5°F of the target. NIST found a 30% undercharge can raise energy use about 16%.
Humidity & IAQ
Winter Humidifiers: How Much Humidity Is Enough, When It Becomes Too Much, and Keeping Them Clean
EPA says keep indoor humidity at 30 to 50% and never humidify above 50%. In cold snaps, window condensation sets a lower ceiling. Research links low absolute humidity to flu virus survival, and CPSC warns dirty humidifier tanks can spray bacteria and mineral dust.
