Got an estimate from this company to have an ac installed. All went well until the very end when the price suddenly went up to because they stated the labor charges were not included with the previous estimate after a long discussion. These things cast doubt with me. Maybe its still the best price but I will obtain other estimates to compare.Trustindex verifies that the original source of the review is Google.

Set your HVAC system to recirculation mode to limit outdoor air intake, upgrade to MERV 13 or higher filters if your system supports them, and schedule a professional duct cleaning if smoke has entered your home. Affordable Heating and Air also installs whole-home air purifiers, such as iWave and REME HALO, for continuous protection against wildfire smoke and other airborne pollutants.
As a general guide, if your system is under 10 years old and the repair costs less than $500, repair is usually the right choice. If the system is 15 or more years old and a repair would cost more than half the price of replacement, replacement typically makes better financial sense, especially with current LADWP heat pump rebates available to offset the cost. Our technicians provide an honest assessment based on your system’s actual condition.

Maintenance


Upon inspection, it was evident that the two Trane units installed by another company had issues from the start. The existing line set, measuring 1 1/4 inches, was not suitable for these units, as 7/8 inches is recommended, with 3/4 inches being an acceptable alternative. Additionally, the system lacked a crucial SS2 safety switch and a sediment trap for the furnace. The absence of an A2L sensor kit at the furnace posed a significant safety risk, especially given the flammable nature of the new refrigerant. Both furnace gas lines were shut off for safety. I devised a comprehensive plan with the homeowner to address these issues by installing the correct line set and the missing components, ensuring the system operates safely and efficiently.


I conducted a maintenance and safety inspection on a Carrier Heat Pump System and addressed an additional service call for an attic ventilation fan. The customer reported the fan running longer than usual and struggling to start. Upon inspection, the thermostat was set too low, causing frequent operation. I adjusted it to 95°F–100°F, allowing the fan to shut off appropriately. The customer also noted the fan repeatedly attempting to start and stop. I explained this could indicate a failing motor or electrical issue. I recommended monitoring the fan and replacing it if problems persist. Given the intermittent operation, I advised proactive replacement to ensure proper attic ventilation and prevent unexpected failure.


I performed preventative maintenance on a Rheem AC unit, ensuring it operates efficiently and cools effectively with an optimal 18.2-degree temperature split. During the inspection, I discovered that the blowers and filters were heavily clogged with dirt. I recommended a thorough cleaning of the blowers and suggested adding air purifiers to all systems for enhanced air quality. I addressed three systems during this visit and plan to locate and service the remaining two systems in my next visit, completing maintenance on all five systems in total.
I performed a thorough replacement of two air filters in the HVAC system. The process began with turning off the system to ensure safety. I then accessed the filter compartment, carefully removed the old filters, and inspected the area for any signs of wear or damage. After recording the specifications of the old filters, I installed the new filters, ensuring they were correctly oriented and securely in place. Finally, I turned the system back on and tested it to confirm proper operation and airflow. The new filters should enhance indoor air quality and improve the efficiency of the HVAC system.
