Spring in Chatham and Lee County means your heating system is winding down and your AC is about to take over for the next five months. This is the window to catch problems before they become expensive summer emergencies. This checklist covers everything Pittsboro, Sanford, and Moncure homeowners should inspect or service on their HVAC and plumbing systems between March and May.
Replace your air filter. If you have not changed it since fall, it is overdue. A clogged filter restricts airflow, increases energy consumption by 5-15% according to the Department of Energy, and puts strain on your blower motor. Use a MERV 8-11 filter for most Chatham County homes — higher MERV ratings can restrict airflow in older systems.
Test your AC before you need it. Turn the thermostat to cooling mode and set it 5 degrees below room temperature. Give it 15 minutes. You should feel cold air at the vents and hear the outdoor unit running. If not, call for service now — not in July when every HVAC company in the Triangle is booked out 2-3 weeks.
Clear debris from the outdoor unit. Chatham County pollen season coats condenser coils with a thick yellow-green layer. Clear leaves, branches, and debris from around the unit. Maintain 2 feet of clearance on all sides. If the coils are visibly dirty, they need professional cleaning — do not use a pressure washer.
Check your condensate drain. The AC produces condensation that drains through a PVC line, usually to the outside of the house. Pour a cup of white vinegar into the drain access point to prevent algae buildup. A clogged condensate drain is the number one cause of AC water damage in Chatham County homes.
Inspect visible ductwork. In your attic, basement, or crawl space, check for disconnected duct runs, visible damage, or duct tape that has dried out and peeled away. Leaky ducts waste 20-30% of your conditioned air according to Energy Star.
Schedule a professional tune-up. A spring AC tune-up includes refrigerant level check, electrical component testing, coil cleaning, and a full system performance evaluation. Cost in the Pittsboro and Sanford area is typically $89-$150.
Note any issues from the heating season. Did the furnace make unusual noises? Did the heat pump struggle on cold nights? Were some rooms colder than others? Write these down and mention them during your spring tune-up so the technician can investigate.
Check the heat pump reversing valve. If you have a heat pump, it should switch cleanly from heating to cooling mode. A stuck reversing valve means you will get heat when you want cool — and this is easier to diagnose and fix now than during a July heat wave.
Verify your thermostat programming. Update your schedule for spring — longer days mean different occupancy patterns. If you still have a basic programmable thermostat, consider upgrading to a smart thermostat. The Ecobee and Google Nest learn your habits and adjust automatically, saving 10-15% on energy costs.
Check thermostat battery. Many thermostats use AA or AAA batteries as backup. Dead batteries mean no AC if power flickers.
Check under every sink. Open the cabinets under kitchen and bathroom sinks and look for moisture, drips, staining, or mold. Small leaks that started in winter may have gone unnoticed for months.
Test all shut-off valves. Turn each valve under sinks and behind toilets a quarter-turn and back. Valves that sit in one position for years can seize up — and when you need them in an emergency, they will not turn.
Flush your water heater. Attach a garden hose to the drain valve at the bottom of the tank and flush until the water runs clear. This removes sediment that reduces efficiency and shortens tank life. Especially important for homes near Jordan Lake and in Moncure where well water carries more minerals.
Check water heater age. The serial number on the water heater label contains the manufacture date. If your water heater is over 8 years old, start budgeting for replacement — the average tank water heater in Chatham County lasts 10-14 years depending on water quality and maintenance.
Test your sump pump. If your home has a sump pump (common in lower-lying areas of Sanford and near the Haw River), pour a bucket of water into the pit to verify it activates and drains properly. Spring rains are coming.
Run water in unused fixtures. Guest bathrooms, basement sinks, and other fixtures that sit idle can develop dried-out P-traps, allowing sewer gas into the house. Run water for 30 seconds to refill the trap.
Inspect hose bibs. Turn on each outdoor spigot and check for leaks at the handle, the spout, and the wall connection behind it. Freeze damage from winter may not be obvious until you turn the water on.
Check irrigation systems. If you have a sprinkler system, run each zone and check for broken heads, misaligned sprayers, and leaks at connections. Chatham County water is not cheap — a broken sprinkler head can waste 10+ gallons per minute.
Clear outdoor drains and gutters. Downspout extensions and French drains should be clear before spring storms. Pooling water near your foundation leads to moisture issues in crawl spaces — a common problem in older Sanford and Pittsboro homes.
Some items on this checklist are DIY. Others need a licensed technician. Here is the breakdown:
| Task | DIY | Professional |
|---|---|---|
| Replace air filter | Yes | |
| Test AC operation | Yes | If it does not cool |
| Clean outdoor unit debris | Yes | Coil cleaning — call us |
| Condensate drain vinegar flush | Yes | If drain is already clogged |
| Check under sinks for leaks | Yes | If you find active leaks |
| Test shut-off valves | Yes | If a valve is seized or leaking |
| Flush water heater | Yes (if comfortable) | We do this during tune-ups |
| Spring AC tune-up | Yes — $89-$150 | |
| Duct inspection | Yes | |
| Sump pump replacement | Yes | |
| Irrigation system repair | Yes — or your landscaper |
March through mid-April is the ideal window. You beat the summer rush, catch problems early, and have time for any repairs or replacements before the first hot week. By May, HVAC companies in the Triangle are booking 2-3 weeks out.
Every 60-90 days for standard 1-inch filters, and every 6-12 months for 4-5 inch media filters. During peak pollen season (March-April in Chatham County), check monthly — you may need to change more frequently. Homes near unpaved roads in Moncure and rural Sanford should check even more often.
New homes in Chatham Park and Briar Chapel benefit from a plumbing check before the 1-year builder warranty expires. Even in a new home, construction debris and builder-grade components can cause issues. We offer free plumbing inspections when paired with an HVAC tune-up.
Standard tune-up pricing is $89-$150 for a single system. This includes filter check, refrigerant level verification, electrical component testing, condensate drain flush, coil inspection, and overall system performance assessment.
No. Covering the unit traps moisture and encourages rust and mold growth. The outdoor unit is designed to withstand weather. Just keep debris cleared and maintain 2 feet of clearance around it.
