Give us a call or shoot us a message and we will gladly come take care of your HVAC needs!!

"Working with Tom was so easy and refreshing. An honest and respectful man that took the time to educate me on how furnaces work. He and Eddie came out within a couple of days to look over my furnace to see if it was repairable. It was over 40 years old so after our discussion of options I decided to replace. Tom sent the quote within a day and it was very fair. Unfortunately, Tom's son got sick on the day of install though Eddie and another gentleman (sorry, can not remember his name) came to do the work. Both were very polite, cleaned up afterwards and patiently answered all question I had. This company is great to work with and would definitely do another job with them. I highly recommend them!"

FAQs for furnace / forced air heating system install or replace projects in San Marcos, CA

Pinpointing an HVAC problem often involves several components, heavy equipment, and high-voltage conditions best left to a licensed technician. Instead of guessing, hire a pro who can diagnose the issue and repair it safely. When requesting estimates from HVAC repair companies near you, share detailed notes about the symptoms, ask what the visit covers, and compare at least two or three quotes before making a decision.

With proper upkeep, most HVAC systems last 15 to 25 years. Annual inspections, filter changes, and coil cleanings help ease the strain on key parts and prevent major breakdowns. Staying on a regular maintenance schedule also protects efficiency and indoor air quality, resulting in lower energy bills and fewer unexpected repairs. In short, plan on at least one professional tune-up each year if you want your system to hit that two-decade mark.

Most manufacturers recommend professional service at least once a year, and twice a year if you own a heat pump system that handles both heating and cooling. These tune-ups let a technician test safety controls, check refrigerant levels, and clean components before minor issues snowball into expensive repairs. Sticking to that schedule keeps warranties valid, boosts efficiency, and can extend the system’s lifespan by several years.

Installing a new HVAC system averages $7,500, but the exact figure hinges on the type of equipment you choose and the size of your home. Swapping out just the AC runs roughly $2,200 to $5,500, while a furnace replacement ranges from $3,200 to $6,000. Although that outlay is significant, newer units deliver better performance and energy savings, so you’ll start earning some of the money back on your utility bills.

Expect to spend between $450 and $2,000 to repair existing ductwork, or between $1,200 and $4,500 for a full replacement. More minor fixes—such as patching leaks, adding insulation, or replacing a damaged vent—cost between $200 and $700. Healthy ducts are crucial to proper airflow, so addressing issues promptly helps your HVAC system run efficiently, keeps energy bills in check, and maintains optimal indoor air quality.
