Frequently Asked Questions

Popping or ticking usually comes from ducts expanding and contracting with temperature changes. Whistling points to restricted airflow or a leak, while rattling may mean loose ductwork or debris. Persistent or worsening sounds deserve a professional inspection before they escalate.

Closing more than a few vents usually does more harm than good. It raises pressure in the ductwork, reduces airflow across the equipment, and can increase duct leakage. Zoning is a far better way to limit conditioning in unused rooms.

Central air suits homes with good ductwork and a gas furnace for heat. Heat pumps add efficient heating to the same ductwork, while mini splits work best in homes or rooms without ducts. Your layout and heating needs decide the fit.

Most manufacturers recommend at least 2 feet of open space around the sides of an outdoor unit and 5 feet above it. Trim shrubs, move stored items away, and keep grass clippings from blowing onto the coil during mowing.

A newer, efficient system is attractive to buyers because it signals lower energy bills and fewer near-term repairs. It rarely returns its full cost at sale, but an aging system can become a negotiating point that lowers offers.

Look for proper licensing and insurance, written estimates, load calculations for new equipment, and clear communication. Charest Heating and Cooling brings 25+ years of heating and cooling work to homeowners across Berkley, MI and explains every recommendation before any work begins.

Turn the system off, slide out the old filter, and note its size. Insert the new filter with the airflow arrow pointing toward the furnace blower, then restart the system. Write the date on the filter frame to track your next change.

A breaker that trips at startup often points to a failing capacitor, a compressor struggling to start, a short in the wiring, or a breaker that has weakened with age. Resetting it repeatedly can cause damage, so schedule an inspection instead.

Pet hair and dander load filters faster, so homes with dogs or cats should check filters monthly. Keep fur trimmed away from floor registers, and protect the outdoor unit from pets that might chew wiring or use it as a bathroom spot.

A technician measures your home, inspects ductwork and existing equipment, and discusses comfort problems before presenting options. Charest Heating and Cooling provides written estimates at no cost to Berkley, MI homeowners, so you can compare systems without pressure or obligation.

Installing central air or a heat pump requires handling refrigerant, which federal rules restrict to EPA-certified technicians. DIY installations also risk voiding manufacturer warranties, failing code inspections, and creating gas or electrical hazards, so professional installation protects both safety and coverage.

Yes, and working with one team simplifies everything. The same technicians who service your furnace and air conditioner can address ducts, filtration, humidity, and UV treatment, spotting connections between problems that separate contractors might miss when working in isolation.

Cover supply and return vents in the work area, turn the system off during heavy sanding or demolition, and change the filter once dusty work ends. Construction debris can clog filters quickly and settle deep inside ductwork if left unprotected.

A full cover can trap moisture and invite rodents, so most technicians advise against it. A breathable top cover or a board over the unit can keep falling ice and debris out. Never cover a heat pump running in winter.
