Common furnace problems we see across San Diego

Our climate is mild but it brings unique challenges. Here is what we see most in local homes.

• Salt air corrosion near the coast. La Jolla Pacific Beach and Point Loma homes often show rust on burners and heat exchangers. Early cleaning and anti corrosion steps help.
• Dust and lint buildup inland. Scripps Ranch Poway and Mira Mesa homes can pack filters and blower wheels with dust during Santa Ana winds. That leads to overheating and short cycling.
• Attic furnace issues in older houses. North Park South Park and Mission Hills have many older homes with tight attics. Poor duct insulation and leaks hurt heat output. We fix and seal ducts to recover lost heat with Duct Sealing and Air Duct Repair.
• Improper venting or flue problems. Ocean Beach and Clairemont homes sometimes have older vents that do not meet current standards. That can affect draft and safety. We correct venting for proper exhaust with a thorough HVAC Inspection.
• Thermostat placement problems. If the thermostat sits near a window or a drafty door the furnace short cycles or runs too long. We can recommend a better location or a smarter control with Thermostat Installation.
• Filter sizing and access. Many tract homes use odd filter sizes hidden behind a grille. We can set up a better filter plan so you do not forget it for months with Media Filter Installation.
• Noisy blowers at night. Townhomes and condos in Mission Valley and University City may have closets near bedrooms. We balance airflow and fix vibration to lower noise with Airflow Balancing.
• Duct leaks and poor airflow. Homes in Chula Vista El Cajon and La Mesa often lose heat in leaky ducts. Sealing and cleaning ducts can bring rooms back into balance and lower bills with Air Duct Cleaning and Duct Sealing.
