Heating & Air Conditioning Repairs

Why is my air conditioner running but not cooling?

Possible causes include a dirty filter, restricted airflow, a thermostat issue, or a problem with the outdoor unit or refrigerant system. Check that your thermostat is set to cool and that your filter and vents aren’t blocked. If the problem continues, schedule service so the cause can be diagnosed.

What should I do if my heating or cooling system stops working?

Check the thermostat settings and batteries, if applicable, and look for a dirty filter. If you notice ice, water around electrical components, or a burning smell, turn the system off and call for service. Avoid opening equipment panels or repeatedly resetting a tripped breaker.

Why are some rooms hotter or colder than others?

Uneven temperatures can come from duct leaks, airflow restrictions, insulation differences, sun exposure, or equipment sizing. Harbin can evaluate the system and help identify whether the issue involves the equipment, ductwork, or the home itself.

Should I repair or replace my HVAC system?

That depends on its condition, repair history, remaining warranty, and the cost of the repair. Frequent breakdowns, poor comfort, and rising operating costs can make replacement worth considering. We can explain the findings and help you compare your options.

Do you offer a free second opinion?

Yes. If you’re facing a major HVAC repair or replacement, contact Harbin about a free second opinion. Share the diagnosis or estimate you received so we can discuss your concerns and arrange the next step.

Maintenance & Seasonal Comfort

How often should I schedule HVAC maintenance?

Plan cooling maintenance before summer and heating maintenance before the colder months. Your equipment’s maintenance requirements may vary, especially if one system handles both heating and cooling year-round.

How often should I change my air filter?

Check your filter monthly and follow the filter and equipment manufacturer’s replacement guidance. Filter type, pets, dust, and system use all affect how quickly it gets dirty. Use the correct size and a filtration level your system can accommodate.

Do you offer maintenance plans?

Yes. Harbin offers maintenance plans to help customers stay on top of routine heating and cooling care. Contact us for current pricing, included services, and plan benefits.

Why does my house feel humid even with the AC running?

Your air conditioner may be cooling the house without removing enough moisture. Equipment sizing, short operating cycles, airflow problems, or moisture entering the home can contribute. We can evaluate the cause and discuss whether system adjustments or a whole-home dehumidifier would help.

Do my air ducts need cleaning?

Duct cleaning isn’t automatically necessary for every home. Visible debris, pest activity, or contamination may warrant an inspection. If your concern is dust or weak airflow, we can also check for filter, duct leakage, and airflow issues before recommending a service.

New Systems & Financing

What size heating and cooling system does my home need?

Square footage alone isn’t enough to choose the right system. Insulation, windows, ceiling height, air leakage, and other factors affect your home’s heating and cooling needs. A load calculation helps determine appropriate equipment capacity.

Does Harbin install Daikin systems?

Yes. Harbin offers Daikin heating and cooling options, including central systems, heat pumps, and ductless mini-splits. We can help compare options based on your home, comfort needs, and budget.

Could a ductless mini-split work for my home?

A mini-split may be a good option for an addition, a room that’s difficult to keep comfortable, or a space without existing ductwork. The right setup depends on the space, electrical supply, and installation requirements.

How much does a new HVAC system cost?

The price depends on equipment size and features, installation requirements, and whether ductwork or electrical changes are needed. An estimate for your specific home is the best way to understand the full cost.

Do you offer financing?

Yes. Harbin offers financing options through GoodLeap and TVA EnergyRight for eligible customers and qualifying projects. Approval, rates, and terms depend on the provider. Visit our Financing Options page to explore both programs.

Is TVA EnergyRight financing available to everyone?

No. Availability depends on your participating local power company, project eligibility, and credit approval. Check the TVA EnergyRight program page to see whether financing is available at your address.

What warranty comes with a new system?

Warranty coverage depends on the equipment and any applicable registration or maintenance requirements. Ask us to explain the manufacturer’s parts coverage and any separate labor coverage included with your estimate.

Generators & Water Heaters

Do you install backup home generators?

Yes. Harbin offers Generac standby generator installation. We can discuss what you want to keep running during an outage and evaluate the equipment and installation requirements for your home.

Can a backup generator run my heating and air conditioning?

It may, depending on the generator’s capacity, your HVAC equipment’s starting and running requirements, and the other loads being powered. Proper sizing helps determine whether the generator can support your system and whether load management is needed.

Do standby generators need maintenance?

Yes. A standby generator needs routine inspections and service according to its manufacturer’s schedule. Maintenance needs also depend on operating hours, especially after an extended outage.

Do you replace water heaters?

Yes. Harbin provides water heater replacement. Contact us with information about your existing unit, the problem you’re experiencing, and your household’s hot water needs.

How do I know whether my water heater needs replacing?

Recurring leaks, unreliable hot water, and repeated repairs can be signs that replacement is worth considering. Some problems can be repaired, while a leaking tank generally requires replacement. An inspection can help determine the cause and your options.

Can I finance a generator or water heater replacement?

Ask our team which financing options are available for your specific project. Eligibility differs by provider and equipment type, so don’t assume every program covers every service.
