8 HVAC Emergency Questions Answered by Someone Who’s Handled 100+ of Them

What This FAQ Covers

If you’re a contractor, property manager, or facility coordinator who’s ever had a gas fireplace or propane heater fail with a deadline looming—this one’s for you. I’ve been on the receiving end of those panicked calls for 8 years now. Below are the questions I hear most (and a couple you probably haven’t thought to ask). I’ll answer them straight, no fluff.

1. What qualifies as an HVAC emergency with Empire Comfort Systems equipment?

Honestly, I’ve seen it all. But the calls that get my full attention are: a gas fireplace that won’t light during a scheduled inspection (the client has guests arriving in 48 hours), a propane heater that cycles on and off erratically in below-freezing temps, and any situation where a thermostat loses communication with the system and you’ve got a building full of tenants complaining.

If you’re wondering, “Is this an emergency?”—ask yourself: will missing the fix cost more than the service call? Usually the answer is yes. In March 2024, I had a 36-hour turnaround on a gas fireplace valve replacement for a hotel lobby. Normal lead time was 5 business days. The client’s alternative was losing a $15,000 event booking. We paid $400 extra in rush fees on top of the $800 base—and delivered. (Note to self: always build a buffer for these.)

3. Is it worth paying extra for rush delivery on replacement parts?

Short answer: yes—if the deadline is real. Everything I’d read about supply chain said “just order early and you’ll be fine.” In practice, I’ve found that even with a 2-week lead time, something can go sideways. A backordered igniter, a wrong part shipped, a trucking delay.

I now treat rush shipping as an insurance policy. For Empire Comfort Systems parts—gas fireplaces, heaters, thermostats—I’ve found that paying for expedited (around 20-30% on top) is worth it when the job is critical. The cost of a redo or a missed deadline is almost always higher. We lost a $12,000 contract in 2022 because we tried to save $150 on standard shipping for a control board. The part arrived 3 days late. The client had already hired someone else.

4. Can I use sprayway glass cleaner on my gas fireplace glass?

Yes—but only if you follow the manufacturer’s instructions. I’ve seen a lot of folks make the rookie mistake of spraying it directly on hot glass (it cracks, and then you’re replacing a $300 panel). Let the fireplace cool completely, spray onto a cloth, wipe, and buff. Don’t use abrasive pads or ammonia-based cleaners—they can etch the glass over time.

Per Empire’s guidelines: use a mild cleaner and a soft cloth. Sprayway is fine, but I’ve also had good luck with a simple vinegar-water mix. (Should mention: always check your specific model’s manual. Some coatings are more sensitive.)

5. Do sound proofing panels actually help with HVAC noise?

That depends on what you mean by “help.” Sound proofing panels (the foam or fiberglass ones) work best for absorbing mid-to-high frequency noise—like a rattling furnace panel or a high-pitched fan. They won’t do much for low-frequency rumble from a compressor or a blower motor.

My experience is based on about 30 retrofit jobs in commercial spaces. If you’re dealing with a loud gas heater, the first step is always: check the mechanicals. Loose panels, unbalanced fans, or worn bearings cause way more noise than a bare wall. Add the panels after you’ve fixed the source. And no, sticking them directly on the unit is not a good idea—fire safety codes (NFPA 54) generally discourage that.

6. How do I remove wallpaper glue before installing a new fireplace surround?

This is one of those questions that seems simple but can ruin your timeline if you get it wrong. I assumed “just get it off with hot water and a scraper” was enough—until the glue residue caused the new stone veneer to fail adhesion. That cost us a redo and a 4-day delay.

What works: use a glue-removing solution (I’ve had good results with a mix of fabric softener and hot water), let it soak for 15 minutes, then scrape with a wide putty knife. Rinse. Then go over it with a light sanding to remove any film. And wait—24 hours of drying—before applying any new adhesive. (Note to self: always test a small area first. Some wall surfaces are more porous than others.)

7. What’s the biggest mistake contractors make when ordering Empire replacement parts?

Assuming the part number is the same for all models in the same series. I’ve made that rookie error myself. In my first year, I ordered a “standard” gas valve for a fireplace insert—turns out the 2021 model used a different valve than the 2023 version. Cost me $600 and a weekend of rework.

The fix: always verify the serial number and manufacturing date before ordering. Empire’s tech support line is actually good about this—just have the unit’s model and serial ready. I also learned to ask: “Is this the most common failure part for this series?” Sometimes a slightly different part (but still OEM) works better.

8. Can I install sound proofing panels myself, or should I hire a pro?

For a single room or office—DIY is fine. I’ve done 6 of my own. But for a commercial space with fire code requirements (which applies to most HVAC closets or rooms with gas equipment), you need a pro who understands fire ratings and adhesive types. Panels that aren’t fire-rated can be a code violation.

Per FTC guidelines on environmental claims (ftc.gov), if you’re marketing a space as “soundproofed,” make sure any acoustic claims are substantiated. A lot of cheap panels claim “soundproof” but only dampen echo by 20-30%. Real sound blocking requires mass—like double drywall or mass-loaded vinyl. My advice: for HVAC equipment noise, focus on vibration isolation first (pads under the unit), then add absorption panels as a secondary layer.
