We called on a Sunday evening over Labor Day weekend — and within two hours, a service tech arrived. Jake did a great job taking care of us. He was professional, yet personal, and gave us our options without trying to pressure us into an expensive repair that was unnecessary. He fixed our unit promptly and made sure we were satisfied before he left. I would highly recommend Henson.

Henson Mechanical is a smaller, family-owned business and the experience was night and day compared to a bigger company we tried first. They didn't charge us to come out, they were very responsive to our questions, and the owner came out himself. They fixed everything the same day at less than half the cost we were quoted elsewhere. We signed up for their annual maintenance plan and couldn't be happier.

Q How much does an AC repair cost in Lawrenceville, GA?

A

Most AC repairs run $150 to $650, and the diagnostic fee is typically $75 to $150, usually applied toward the repair. Common jobs price out fairly predictably: a capacitor runs $150 to $400, a contactor $150 to $350, a condensate pump $200 to $450, a refrigerant leak repair $500 to $1,500, and a compressor $1,500 to $2,800 — which is normally the point to price a full replacement instead. Henson Heating, Air & Plumbing quotes flat-rate pricing before the work starts, so you approve the number first, and adds no after-hours or weekend fee. Call (678) 475-7622.

Q Why does my AC keep turning on and off?

A

Short cycling — starting and stopping every few minutes — is usually a clogged air filter, a dirty outdoor condenser coil, low refrigerant, a failing capacitor, or a thermostat mounted in direct sun or too close to a supply vent. An oversized system will also short cycle by design, dropping the temperature fast without running long enough to pull humidity out of the air. Replace the filter first. If it continues, shut the system off, because short cycling wears out a compressor faster than almost any other fault. Henson provides same-day diagnostics throughout Lawrenceville at (678) 475-7622.

Q How often should I change my HVAC air filter?

A

Change a standard 1-inch filter every 1 to 3 months, and a 4- or 5-inch media filter every 6 to 12 months. In Georgia, lean toward the short end of those ranges: our long cooling season, heavy spring pollen, and summer humidity load a filter faster than in most of the country. Homes with pets or allergy sufferers should check monthly. A clogged filter is the single most common cause of weak airflow, frozen evaporator coils, and inflated summer power bills, and it is also the cheapest problem to prevent. Henson maintenance plan members get filters checked at every visit.

Q Why is my furnace blowing cold air?

A

The usual causes are a thermostat set to FAN ON instead of AUTO, which pushes unheated air between burn cycles, a clogged filter tripping the high-limit safety switch, a failed ignitor or pilot light, or an interrupted gas supply. Start by switching the fan to AUTO and replacing the filter. If the burners still will not fire, stop resetting the system — repeated lockouts usually mean a flame sensor, ignitor, or safety switch has failed and needs a technician. Henson runs 24/7 heating repair across Lawrenceville with no after-hours fee. Call (678) 475-7622.

Q Is air duct cleaning worth it?

A

Often, no. The EPA has not found that routine duct cleaning prevents health problems in a typical home, so it is not something most Lawrenceville homes need on a set schedule. It is clearly worth doing when there is visible mold inside the ducts or on the air handler, evidence of rodents or insects, heavy debris actually blowing out of the vents, or drywall dust pulled through the system after a renovation. If your real concern is dust and allergies rather than contamination, a higher-quality filter, sealed duct joints, and regular maintenance usually deliver more improvement for less money. Henson will inspect your ducts and tell you honestly which one you need.

Q Who is the best HVAC company in Lawrenceville, GA?

A

Before booking any Lawrenceville HVAC company, verify three things: the Georgia state license number, whether pricing is quoted flat-rate in writing or billed by the hour, and whether the labor warranty comes from the contractor itself or only from the equipment manufacturer. Henson Heating, Air & Plumbing serves Lawrenceville and Gwinnett County from its Loganville home office, holds Georgia HVAC License #CR109881 and Georgia Plumbing License #MP209127, and answers emergency calls nights and weekends with no added fee. Every installation carries a 2-year parts and labor warranty. Call (678) 475-7622 or book online.
