HVAC and Plumbing Frequently Asked Questions

When you have questions about HVAC and plumbing, the team at Classic Aire Care has the answers you can depend on. The following are some of the most common plumbing and HVAC FAQs that our clients contact us to learn more about.

Rattling, banging, whistling — it’s usually your system trying to tell you something’s off. It could be a loose part, a worn-out motor, or an airflow issue. The sooner we take a look, the easier it is to fix without major repair costs.

Every commercial refrigeration and HVAC system is different. At a minimum, you will want to conduct regular service on your systems biannually. For best results, a monthly service call is advisable for most systems.

It can — especially with the right add-ons. We install whole-home UV light air purifiers, dehumidifiers, and advanced filters that help reduce dust, allergens, germs, viruses, and airborne irritants, so your family can breathe easier.

Routine maintenance is step one. From there, we suggest upgrading to a programmable or smart thermostat, sealing your ducts, and possibly improving insulation. These simple changes can lead to big savings.

Our air conditioning maintenance plans give you peace of mind. Our seasonal tune-ups include the following

  • Changing or cleaning the air filter
  • Lubricating the blower motor pulleys and bearings
  • Cleaning the condensate drain and drip tray
  • Checking the safety systems
  • Inspecting the condenser unit
  • Checking for refrigerant leaks
  • Cleaning the supply plenum
  • Checking for loose duct connections
  • Cleaning the evaporator coil
  • Cleaning the condenser
  • Verifying the unit operates properly in all settings 

We also offer a membership plan for your plumbing and furnaces, so we can keep track of your regular maintenance with prepaid appointments.

If your system is over 12 years old, struggles to keep your home comfortable, or needs frequent repairs, it might be time to consider a replacement. We’ll walk you through your options without the pressure — just honest recommendations based on what’s best for your home.

There’s no one-size-fits-all answer here. We take into account your home’s layout, insulation, square footage — even sun exposure — to recommend the right-sized system. It’s the best way to get reliable comfort and better energy efficiency.

In many cases, yes. Today’s high-efficiency models are designed to use less energy and lower your monthly utility bills. Plus, you may qualify for tax credits or rebates that help offset the upfront cost.

Most home AC units last between 15 and 20 years. With regular care and strict adherence to maintenance schedules, it is possible to extend this lifespan.

Yes, we offer a few financing options to make the transition an easy one. We’ll guide you through the process and help you find financing options that fit your budget, so you can enjoy year-round comfort without delay. Financing is available for qualified borrowers and is subject to approval by a third-party financing provider. 

Whether it’s a shower drain at home or a floor drain in the storeroom, there are many reasons your drain can clog. Over time, hair, food debris, grease, and other items deposited in the drain form a clog that must be cleared through mechanical or chemical means. The more material deposited into the drain, the greater the likelihood that a clog will form.

Drips can occur when couplings come loose, hoses are punctured, or condensation forms. In most cases, small drips are easily corrected by tightening components, patching holes, or adjusting temperature settings on a cooling system. If you’re experiencing water leaks but are not sure of the source, leak detection and repair are your answer. 

We’re not just here to fix things — we’re here to support you. Our team takes pride in the work we do and the relationships we build. We stand behind every job with experience, transparency, and a real commitment to your absolute comfort.

Your heating, cooling, and plumbing systems don’t stick to a schedule when it comes to breakdowns. Whether it’s 8 a.m. on a Monday or 9 p.m. on Christmas Eve, our trained HVAC technicians are available to perform the repairs your system needs.

You want to check the company’s accreditation, experience, and reputation. Make sure the company has a solid reputation with the BBB and request referrals from recent clients. It’s also vital to ensure that the technicians you hire have the skills and experience required to service your specific HVAC systems, commercial refrigeration units, plumbing systems, etc.

Top notch install quality. While my ac wasn’t that old, I opted for a higher efficiency heat pump system and replace my worn-out older furnace! The difference in my home is night and day difference, can’t wait to see what the bills do.
