Heating and Air Conditioning questions, answered by experts

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?
