Question 1

Is it an emergency (no heat in winter, gas smell)?

Accepted Answer

If you smell gas, leave the house and call your gas company first. No-heat situations in freezing weather qualify for emergency service — tell the dispatcher so they can prioritize. Emergency HVAC calls typically cost more than scheduled visits.

Question 2

What type of system do you have?

Accepted Answer

Central air, heat pump, mini-split, furnace, boiler — the tech needs to know before arriving. If you're not sure, check the unit label or send a photo of the indoor and outdoor units.

Question 3

When was the system last serviced?

Accepted Answer

Annual maintenance is standard. If your system hasn't been serviced in years, mention it — the tech may need to do a full tune-up before diagnosing a specific issue.

Question 4

What exactly is happening — or not happening?

Accepted Answer

Is it blowing warm when it should be cold? Making a noise? Short-cycling? Not turning on at all? Specific symptoms narrow the diagnosis and let the tech bring the right parts.

Question 5

Have you checked the thermostat and filter?

Accepted Answer

A dead thermostat battery or a clogged filter causes most 'system not working' calls. Check both before scheduling — you may save yourself a service fee.

Question 8

What is a HVAC tonnage?

Accepted Answer

A unit of measure for air conditioning capacity. One ton equals 12,000 BTU/hour of cooling capacity. Residential AC systems typically range from 1.5 to 5 tons. Proper sizing is critical: an undersized system can't cool the home adequately, while an oversized system short-cycles (turns on and off frequently), wastes energy, and fails to dehumidify properly. System size is determined by a Manual J load calculation that considers square footage, insulation, window area, climate zone, and occupancy. A 2,000 sq ft well-insulated home in a moderate climate typically needs a 3–3.5 ton system.

Question 9

What is a Central air conditioning?

Accepted Answer

Central air conditioning is a whole-home cooling system that uses a single outdoor compressor/condenser unit connected to an indoor evaporator coil mounted in or near the furnace. Cooled air is distributed through the same ductwork used for heating. A central AC system is sized in tons (1 ton = 12,000 BTU/hr), with most homes requiring 2–5 tons depending on square footage, insulation, climate, and window area. Installation typically costs $3,500–$7,500 for the equipment and $1,500–$3,000 for labor if ductwork already exists. Adding new ductwork can raise the total to $10,000–$15,000+. Central systems are more efficient and quieter than window units, and a properly sized system can reduce humidity as well as temperature. Efficiency is measured by SEER (Seasonal Energy Efficiency Ratio) — current federal minimums are SEER 14–15 depending on region, while high-efficiency models reach SEER 20+. A central AC system typically lasts 15–20 years with annual maintenance. Homeowners should change the filter every 1–3 months and schedule professional maintenance before each cooling season.

Question 10

What is a SEER rating?

Accepted Answer

Seasonal Energy Efficiency Ratio — the standard measure of air conditioner and heat pump cooling efficiency. It's calculated by dividing the total cooling output (in BTU) over a typical cooling season by the total electrical energy input (in watt-hours). Higher SEER means lower operating costs. As of January 2023, the US minimum is SEER2 14.3 in the North and 15.2 in the South. Mid-range units are SEER 16–18; premium units hit SEER 20–26. Each point of SEER improvement saves roughly 7% on cooling costs. When shopping for AC, compare SEER alongside upfront price — a higher-SEER unit costs more but may pay for itself in 5–8 years through lower bills.

Question 11

What is a Energy Star certification?

Accepted Answer

A voluntary US government-backed label indicating that a product meets strict energy efficiency criteria set by the EPA and Department of Energy. For HVAC equipment, Energy Star certification means the unit exceeds minimum federal efficiency standards by a significant margin — typically 10–15% for central AC, 8–10% for furnaces, and 15–20% for heat pumps. Energy Star-certified products often qualify for utility rebates ($200–$500) and federal tax credits (up to $2,000 for heat pumps under the Inflation Reduction Act). The label covers appliances, windows, insulation, and even entire homes. When comparing products, Energy Star is a reliable floor — but the Most Efficient sub-label identifies the top performers within each category.

Question 12

What is a Mini-split (ductless heat pump)?

Accepted Answer

A ductless heating and cooling system consisting of an outdoor compressor/condenser unit connected by refrigerant lines to one or more indoor air-handling units ("heads") mounted on walls or ceilings. Unlike central HVAC that pushes conditioned air through ductwork, mini-splits deliver heating and cooling directly into individual rooms or zones, eliminating the 25–30% energy loss typical of ducted systems. Each indoor head has its own thermostat and remote control, allowing different rooms to be set to different temperatures — or turned off entirely when unoccupied. Single-zone systems (one outdoor unit, one indoor head) cost $1,500–$4,000 installed and are ideal for room additions, converted garages, or supplementing central HVAC in problem rooms. Multi-zone systems (one outdoor unit, 2–5 indoor heads) cost $3,000–$10,000+ and can replace central HVAC entirely. Modern inverter-driven mini-splits achieve SEER2 ratings of 20–42 (vs. 14–18 for typical central AC), making them 30–60% more efficient. In heating mode, cold-climate models (Mitsubishi Hyper-Heat, Fujitsu XLTH, LG Red) produce heat down to -13°F (-25°C) at COP ratings of 1.5–2.0, meaning they produce $1.50–$2.00 of heat per $1.00 of electricity consumed. Installation requires a licensed HVAC technician: mounting the indoor head, running refrigerant lines through a 3-inch wall penetration, connecting electrical, and performing vacuum and charge testing. Line-hide covers ($150–$300) conceal exterior refrigerant lines for cleaner aesthetics. Most installations complete in 4–8 hours per zone.
