HVAC Issues We Diagnose & Fix
If your system is showing any of these symptoms, don’t wait. Most HVAC problems get worse — and more expensive — the longer they go unaddressed. Our technicians diagnose the root cause on the first visit.
AC Not Cooling
System runs but air is warm or room temperature never drops. Common causes: low refrigerant, failed compressor, dirty evaporator coil, or blocked airflow.
No Heat from Furnace
Furnace won’t ignite or starts then shuts off quickly. Could be a faulty igniter, failed thermocouple, cracked heat exchanger, or control board issue.
High Energy Bills
A sudden spike in heating or cooling costs often signals a failing component, refrigerant leak, or duct loss. We run a full efficiency diagnostic to identify where the system is losing energy.
Uneven Temperatures Room to Room
Some rooms too hot, others too cold — usually caused by duct leaks, improper zoning, or an undersized unit.
Strange Noises from the Unit
Banging, squealing, rattling, or clicking sounds indicate loose components, worn bearings, or a failing motor. Left unaddressed, mechanical issues escalate quickly.
Short Cycling
System turns on and off in rapid, short bursts. Causes include refrigerant issues, dirty filters, oversized equipment, or a failing thermostat.

What Homeowners Say About NorTech HVAC
“AC went out on a Friday afternoon in July. NorTech had a tech at my door by 6pm and the unit was running before 8. I was honestly expecting to sweat through the weekend. Crew was professional and fast.”
“Had a new furnace installed last fall. The crew showed up on time, laid down floor protection, and had the old unit hauled out and the new one running in about six hours. Clean work, no mess left behind.”
“Signed up for the maintenance plan and the spring tune-up was thorough — they caught a refrigerant issue I didn’t know about. Took slightly longer than quoted but the tech explained everything clearly.”
“They installed a mini-split in my garage workshop and it made a world of difference. The tech walked me through the zone settings and made sure I understood how to use it before leaving. Very happy.”
“Duct cleaning was long overdue. The before and after airflow difference was noticeable immediately. Tech showed me photos of what they pulled out. House feels completely fresher now.”
“Heat pump installation went smoothly. They handled everything start to finish and my energy bills dropped the first full month. Would have given 5 stars but scheduling took a couple extra days.”
HVAC Services — Frequently Asked Questions
Answers to the most common questions homeowners ask before scheduling service.
If your AC unit is under 10 years old and the repair cost is less than half the price of a new system, repair is usually the better choice. Units over 15 years old with frequent breakdowns or rising energy bills are strong candidates for replacement. Our technicians provide a full diagnostic before recommending either option.
HVAC systems should be serviced twice a year — once in spring before cooling season and once in fall before heating season. Regular tune-ups extend equipment life, improve efficiency, and catch small problems before they become costly repairs.
A heat pump is a single system that handles both heating and cooling by transferring heat rather than generating it. It is highly efficient and ideal for moderate climates. NorTech technicians can assess your home’s insulation, climate zone, and existing ductwork to determine if a heat pump is the right fit.
A standard furnace installation typically takes 4 to 8 hours depending on the system size, existing ductwork conditions, and any code upgrades required. Our crews arrive with the equipment staged and complete the job in a single visit in most cases.
Our duct cleaning service includes a full inspection of supply and return ducts, high-powered vacuum extraction of dust, debris, and allergens, sanitization treatment, and a post-cleaning airflow test. We also check for leaks and seal any gaps found during the service.
A mini-split is a ductless heating and cooling system that conditions individual rooms or zones without requiring ductwork. They are ideal for home additions, garages, older homes without existing ducts, and any space where extending ductwork is impractical or cost-prohibitive.
HVAC service costs vary based on system type, the scope of work, parts required, and your location. NorTech provides upfront estimates before any work begins so you know exactly what to expect. Use code NORTECH15 for 15% off your first service.
