I've struggled to find an honest HVAC company in San Diego to service my home, but I am glad I came across Same Day Heating & Air Conditioning online. I called and spoke to a professional representative who quickly sent a tech to my house. The technician arrived promptly and was helpful and knowledgeable. He had the issue diagnosed and fixed within 30 minutes, and at a reasonable cost. I will continue to use this company for all of my needs and am thankful for their assistance. I highly recommend them!

I had several other contractors out to fix my fairly new furnace that had stopped working around Christmas. They all put parts in, only to have it stop working almost immediately. The technician from Same Day Heating and Air Conditioning found the actual problem to be nothing more than a dirty sensor. He quickly fixed and inspected the attic and found two air vents were almost completely disconnected. We had questioned our high utility bills during the hottest months when running the AC, this was likely the issue. We were impressed that he went the extra mile and we will be replacing the damaged venting before summer with Same Day! Thanks again

Wow, very impressed and lived up to their name! Called looking for a quote for some AC duct work and replacing a 20 yr old AC unit, super polite and responsive over the phone. AC Technician was extremely knowledgeable and professional, didn't try to sell me, was great about telling me what my options were and didn't quote anything unnecessary. Ended up getting a new system and paid exactly what was quoted. Seriously top of the line service! Thanks Same Day!

I got the call from our short term rental visitors that our air conditioner was not working. They were hot, annoyed, and not very friendly. I was 500 miles away but needed to get this thing fixed ASAP. I searched around for someone that could get to the home quickly and get this thing fixed. I came upon Same Day's promo offer for $99.00 diagnostic (the fee was waived!). From the moment I first called all the way through the diagnostic and fix the communication was top notch. Professional service, courteous technicians, and super reasonable pricing. Not to mention they came to the house and had the unit fixed in a matter of a couple of hours. The tenants even called me to thank me for sending such a professional, courteous technician. 5 star company all day.

The Same Day Guarantee For Heater Replacement

Mandatory Quality Checks

You need more than a technician. You need expertise you can trust. That’s why we determine which model is right for you based on your home size, type and usage patterns. After the installation, we perform a mandatory quality check within 48 hours after the installation.

Get A Complimentary Tune-Up

We need to get it right. Even though we offer a 24-month satisfaction guarantee, we schedule a complimentary tune-up four months after installation. We’ll also purchase the heater manufacturer’s warranty on behalf of our customers for additional coverage and flexibility.

How Much Does Heater Installation Cost?

The biggest cost factor will be home size and your choice of Annual Fuel Use Efficiency, which costs more up front but save you over the long haul. Whether you use a gas furnace or an electric heat pump, your energy and choice of heating source is a big factor. We recommend electrical for low cost of installation, minimal upkeep and longevity.
