The Union29379 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Loud banging on start-up (compressor slugging)

Frozen evaporator coil or ice on the refrigerant lines
Musty or burnt smell the first time the system runs
Skyrocketing utility bills with no change in usage
Heating and air conditioning service built around Union
Most of the work we do in Union starts the same way: the system is running but the house is not comfortable. Before we replace anything, we measure airflow, static pressure and temperatures so you are paying for the actual fault.
A large share of the equipment we service in Union was installed by a builder to a minimum spec. That usually means an undersized return, a cheap filter rack and a condenser sitting close to a wall.
Heating season here is December through February. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

Union29379 HVAC questions, answered
How often should I change my filter in 29379?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Union with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
What does a new system cost in Union?
A complete residential replacement in the 29379 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Union, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Union we see algae and dust clogging drain lines constantly during April through October. It is a fast fix but ignoring it ends in ceiling damage.
How much does an HVAC service call cost in 29379?
A diagnostic visit in Union typically runs $75 to $150, and that fee is usually applied toward the repair if you approve the work. Repair prices are quoted as a flat rate before we start, so the number you approve is the number you pay regardless of how long the job takes.
Do you offer maintenance plans?
We do. A two-visit plan in South Carolina covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
