Answers to Your Most Common HVAC Questions

  • How do I know whether my HVAC system needs a repair or a full replacement?

    Replacement is not always the right call. At Eric's Heating & Air, we follow a fix-first approach, meaning we evaluate whether your existing unit can be repaired at a reasonable cost before recommending anything new. Even older or antique systems can often be extended with the right repair. Factors like the age of the unit, the cost of the needed repair relative to a new system, and the efficiency of what you currently have all play into that decision. We give you a straight assessment, not a sales pitch.

  • What does a diagnostic service call cost, and what does it include?

    Our diagnostic call charge is $70, which is lower than what most regional competitors charge. That call covers a thorough evaluation of your system so we can identify what is actually wrong. We do not charge extra just to show up. If a repair is needed, we will walk you through what it involves and what it will cost before any work begins. For installations and replacements, we back our pricing with a best price guarantee, so you know you are getting a fair deal.

  • What are the most common heating and air conditioning problems you see in the New River Valley?

    In the Christiansburg and Blacksburg area, we regularly deal with blower belt issues that cause a high-pitched squealing sound, worn ball bearings that create a scraping noise, loose panels or ductwork that rattle or ping, and pilot lights that burn yellow instead of blue, which can signal a carbon monoxide concern. On the cooling side, clogged condensate lines, dirty filters, and failed electronic boards come up frequently. Leaking water heaters are also common service calls. Most of these issues are repairable without replacing the whole system.

  • Do you offer emergency HVAC service, and how fast can you respond?

    Yes. We are available 24 hours a day, 7 days a week, 365 days a year. For air conditioning emergencies, our target response time is under 3 hours. We also service heating emergencies during extreme weather, including winter storms. Our trucks are equipped with 4-wheel drive, so we can reach clients in unplowed conditions when other companies cannot. We carry a 3-month warranty on specific emergency repairs, and all of our work is backed by a 100 percent satisfaction money-back guarantee.

  • When is the best time to schedule heating and cooling maintenance?

    The best times for HVAC maintenance are spring and fall, before the seasons when your system works hardest. A spring tune-up prepares your air conditioning for the humidity and heat of a Virginia summer, while a fall check gets your furnace or heat pump ready for cold weather. Regular maintenance helps catch small issues before they become costly failures, extends the life of your equipment, and keeps your system running efficiently. Given the temperature swings in the Appalachian region, staying ahead of seasonal demand is well worth the effort.

  • What HVAC brands does Eric's Heating & Air work with?

    We are an authorized Trane dealer, which means we have direct access to Trane equipment and can back installations with manufacturer support. Beyond Trane, our technicians are experienced with Mitsubishi Electric, Daikin, Carrier, LG, Samsung, and York systems. Whether you have a brand-specific unit or a system that needs diagnosis regardless of manufacturer, we have the technical background to handle it. Our goal is always to match the right equipment to your home or building, not to push a particular brand for its own sake.

  • Can you service older or antique HVAC systems, or do you only work on newer equipment?

    We work on older systems regularly and take pride in doing so. Many larger companies will push for a full replacement the moment a system shows its age, but that is not how we operate. If a unit can be repaired in a way that genuinely benefits you financially, we will fix it. We have kept aging systems running well past the point where other contractors would have walked away. If a repair no longer makes financial sense, we will tell you that honestly and help you choose a replacement that fits your budget.

  • Do you serve areas outside of Christiansburg and Blacksburg?

    Yes. Our primary service area covers Christiansburg, Blacksburg, and Montgomery County broadly. We also regularly serve Radford, Shawsville, Elliston, Riner, Pilot, Floyd, and Salem. For select installation projects, we extend service into Giles County and Dublin as well.
