Common HVAC problems in Lancaster, OH homes

  • AC not cooling or short-cycling during humid summer days — often caused by low refrigerant, clogged coils, or failing compressors
  • Uneven heating or cold spots in older Lancaster homes — frequently due to duct leaks, poor insulation, or undersized systems
  • Rising energy bills in both summer and winter — signs of inefficient equipment, dirty filters, or failing components
  • Excess dust, musty odors, or allergy flare-ups — symptoms of inadequate filtration or dirty ductwork
  • Frequent pilot or ignition issues with boilers and furnaces — common with age and lack of maintenance
  • Hot water shortages or leaks — aging water heaters, sediment build-up, or failing valves
  • System failures during extreme weather — delayed repairs that could be prevented with annual maintenance

Diagnostic approach — what to expect when a technician arrives

  1. System history and symptom review: We start by asking about when the issue began, noises, smells, or recent changes to performance.
  2. Visual and electrical inspection: Safety checks first — wiring, breakers, filters, and visible components.
  3. Performance testing: Refrigerant pressures, airflow measurements, combustion analysis for gas systems, and thermostat calibration.
  4. Duct and airflow assessment: Inspecting ducts for leaks, blockages, or poor insulation affecting comfort and efficiency.
  5. Clear explanation and options: You receive an easy-to-understand diagnosis, repair options, expected lifespan estimates, and efficiency impacts — including replacement recommendations when repair is no longer cost-effective.

Repairs, replacements, and installations explained

  • AC repair: Common fixes include refrigerant recharge, capacitor and contactor replacement, fan motor service, and coil cleaning. We prioritize repairs that restore efficient, reliable cooling.
  • AC replacement & installation: When systems are over 10–15 years old or repairs are frequent, replacement with a properly sized, high-efficiency unit will lower bills and improve comfort. Installations include duct inspection and necessary upgrades for optimal airflow.
  • Furnace and boiler service: Repair work often involves ignition systems, heat exchangers, motors, and flame sensors. Full replacements include system sizing, venting checks, and safety testing.
  • Heat pumps and ductless mini-splits: Ideal for Lancaster homes seeking energy-efficient heating/cooling without ductwork. Installations include load calculations, line-set routing, and refrigerant charging to manufacturer specs.
  • Water heaters and tankless systems: Repairs typically involve thermostats, heating elements, valves, and anode rods. Tankless installations are recommended for households prioritizing continuous hot water and higher efficiency.
  • Air duct cleaning & IAQ upgrades: Duct cleaning removes built-up dust and allergens. IAQ enhancements — upgraded filters, whole-home UV, and humidification control — improve health and extend equipment life.

Preventative maintenance and the SAM plan

Routine maintenance is the most effective way to avoid emergency repairs and extend equipment life. The SAM service agreement plan offers:

  • Scheduled annual inspections for heating and cooling systems
  • Priority scheduling and faster diagnosis
  • 15% discount on eligible service calls
  • Routine tune-ups that improve efficiency and lower utility bills
  • Documented reports that help plan future replacements and budgetingThese planned visits typically include filter replacement checks, electrical tightening, refrigerant and combustion testing, lubrication, and airflow balancing.

Indoor air quality and duct cleaning — why they matter here

Lancaster residents experience pollen in spring, high humidity in summer, and indoor dryness in winter. These seasonal conditions make IAQ solutions particularly important:

  • Filtration upgrades trap finer particles and reduce allergens
  • Humidifiers prevent dry air damage in winter and improve comfort
  • Dehumidification and proper AC sizing reduce mold risks in summer
  • Duct cleaning restores airflow and removes dust, pet dander, and construction debris

Financing, warranties, and licensing

  • Financing options are available to help spread the cost of major replacements or high-efficiency upgrades; terms and availability depend on specific projects.
  • Most new equipment installations include manufacturer warranties; installation workmanship is covered according to local licensing and service terms.
  • Licensed in Ohio (License #22118) and experienced with local code requirements and permit processes relevant to Lancaster and Fairfield County installations.

Why timely HVAC service matters in Lancaster

  • Prevents emergency breakdowns during extreme seasonal weather
  • Reduces energy costs through improved system efficiency
  • Extends equipment life and delays expensive replacements
  • Improves home comfort and indoor air quality for allergy season and humidity swings
  • Helps maintain property value and supports safer, cleaner hot water and heating systems

Maintenance tips for Lancaster homeowners

  • Replace filters every 1–3 months during heavy use seasons
  • Keep outdoor AC units clear of debris, leaves, and overgrown vegetation
  • Schedule annual heating system checks before cold weather arrives and AC tune-ups before summer
  • Insulate accessible ductwork in attics and crawl spaces to reduce heat loss/gain
  • Flush water heaters annually in high-mineral areas to reduce sediment buildup

These guys are great! Matt S. came out on Tuesday afternoon to perform a diagnostic check, and was able to return Thursday to install a new evaporator. Very professional and organized, and went above and beyond in performing the job. I will be using Best Service again in the future for all of my heating and cooling needs!

Kate N.

Had a furnace installed yesterday - Donnie managed our project and Brandon and Austin installed. All through the process, we felt informed and not pressured into doing/buying anything (not the experience we had we OTHER companies who we called for estimates). Recommend Best Service 100%. Fair prices, great service

Every person I have dealt with has been super nice and professional. I have used them twice...one for a repair and once for a replacement. They are up-front, honest, amazingly friendly and professional. This is the kind of company I enjoy doing business with and they are my go-to for HVAC. I highly recommend them!

Excellent service. First much appreciation for Angel's efforts to get a technician to us quickly. Brandon arrived in short order and conducted an exhaustive effort to diagnose the problem and restore our furnace operation. Thank you for a job well done.
