Get answers to common questions about hvac services in Monrovia, California.
For a standard single-family home in Monrovia, a full AC replacement typically ranges from $5,000 to $12,000. The final cost depends heavily on the system's size (tonnage), efficiency rating (SEER2), and the complexity of the installation, such as ductwork modifications. Given our hot San Gabriel Valley summers and California's Title 24 energy codes requiring high-efficiency systems, investing in a unit with a SEER2 rating of 14.3 or higher is common and can affect the upfront cost but provides long-term savings on SCE bills.
The absolute best time is during the spring (March-May) or fall (September-November), before the intense summer heat or occasional winter chill arrives. Scheduling during these shoulder seasons ensures your system is ready for peak demand and provides much greater availability for HVAC companies, often leading to faster service and potential promotional pricing. Avoid waiting until the first major heatwave in June or July, as service wait times can be lengthy.
Yes, several key regulations apply. First, all HVAC contractors must be licensed by the California Contractors State License Board (CSLB). Secondly, due to California's strict refrigerant regulations, only EPA-certified technicians can handle refrigerant. Finally, for replacements, systems must meet the latest Title 24 energy efficiency standards (SEER2), and the work often requires a permit from the City of Monrovia's Building & Safety Division to ensure it meets current codes.
Always verify the company holds a valid CSLB license (you can check online) and carries both liability and worker's compensation insurance. Look for established local companies with strong reviews on platforms like Google or Nextdoor, as they understand the specific needs of Monrovia's older homes and microclimates. A trustworthy provider will perform a detailed load calculation (Manual J) for new equipment, not just base it on your old system's size, and provide a clear, written estimate.
It is normal for systems to have longer run times during multi-day heatwaves where temperatures exceed 95°F, which are common in Monrovia. However, you should be concerned if the system never shuts off, fails to lower the indoor temperature by 15-20 degrees, or if your energy bills are skyrocketing compared to neighbors. This often indicates issues like low refrigerant, a failing compressor, dirty coils, or an undersized system, all of which require a professional diagnostic.
