"Nathan and Gordon at Total Home Environmental are lifesavers! I was facing estimates of $10,000 to $20,000 to replace my entire AC and heating system but instead they indicated that my 25 year-old AC compressor could be resuscitated by thoroughly cleaning the terminals and adding a hard-start kit. No other HVAC technician that came out gave me this option but they pulled it off for a fraction of the price of a new install!!! They are honest and knowledgeable professionals! Thank you so much!"

"Air Tech was great. I would HIGHLY recommend. I initially had 2 other companies besides Air Tech come out for a replacement estimate. Price wise Air Tech was right in the middle but were doing a lot more than the other 2 quotes I got. For example they were changing the copper refrigeration lines, which the other 2 weren’t going to do. When I called the other 2 companies to add the lines in there was going to be an additional $1500-$2000 charge. I’m very pleased with this the work that was done by Air Tech"

FAQs for heat pump repair or service projects in Diamond Bar, CA

Heat pumps move air to cool or warm your home during different seasons. In cold weather, they extract heat from the outdoors and bring it inside to warm your home. In warm weather, they remove heat from your home to keep it cool. This efficient heat transfer increases indoor comfort, improves energy efficiency, and reduces the need for additional heating systems.

Replacing a heat pump costs between $4,200 and $7,900. The actual cost depends on the type of heat pump. Geothermal models are the most expensive to replace, with the price of the unit plus labor ranging between $6,000 and $20,000. Air source models cost between $4,500 and $8,000 to replace, while the replacement costs for a mini split unit run between $1,300 and $8,000.

The average heat pump is designed to last about 14 years, roughly the same as a central air conditioning system (12 to 15 years). Newer models can last 20 years or more. How long your heat pump lasts depends on how frequently you use it and whether you perform routine maintenance like annual tuneups.
