Relay

« Back to Glossary Index

A relay is an electrical device that uses a small electric current in a control circuit to power an electromagnet. This electromagnet then opens or closes a switch in a separate, larger operating circuit. In HVAC systems, relays are often used to control components like compressors, fans, or valves, allowing a low-power control signal to manage high-power equipment safely and efficiently.

Paradise Heating and Air was great to work with—professional, on time, and very thorough.

Jonathan was great to work with. He came within a couple of hours after I called at around 4pm. and had us operational around 12 the next day (because he didn’t have a motor for my condensor and had to get one the next day). Will definitely use him again.

Awesome Work! Great Experience with Jonathan and Paradise Heating and Cooling Great experience from Jonathan and Christian! Job: Disassemble and remove old attic ductwork and install new ductwork and runs. Install Accuclean air filter in both attic and main floor systems. Install new smart thermostat and attic insulation infill. 1. Honest assessment of what is needed and more importantly, what is not needed. And not just trying to sell the most expensive option. 2. Competitive and reasonable quote. 3. I asked about radiant heat treatment as an add on, but he said while they could do it, it would not have efficient results and not worth the investment since I had a high hip roof and large attic area. 4. Great work ethic and work product. Duct system, filtering system and thermostat expertly installed, set up and running effectively. 5. All interactions cordial, efficient and polite. 6. Punctual in accordance with automated notices about arrival and appointment reminders 7. Clean work - brought coverings to reduce tracking of insulation through house areas traversed. Cleaned any evidence of insulation. 8. Works relatively quietly. No loud talk or music. 9. Small footprint on street. One van. I expected van and trailer. New materials brought in, unloaded and installed while old duct system all loaded up and removed. Very efficient. Overall, fantastic experience and is highly recommended.

Paradise answered my call late at night and made me an appointment for first thing in the morning and even showed up early. They crawled under my rental house through the dirt and mud to inform me that my landlord had me living in a dangerous environment. He was upfront and honest about everything and let me know the steps I needed to do to get my family out of this situation. No bandaid fixes from these guys, they do things in a professional manner and I couldn’t be more appreciative. Top notch customer service. Highly recommend!

If you are having any HVAC issues please do not hesitate to call Paradise Heating and Air. Mr. Jonathan and his team were quick and provided answers to all my questions. I appreciate how quick they came out and fixed my issue being that we have had some extremely hot temperatures lately. I look forward to working with them in the future. I will be recommending them to anyone who has an issue. Thanks again to Paradise Heating and Air.

Jonathan and his helper were awesome. Keeping us informed as to what they were doing as they replaced our heating and air units. They were pleasant to have around and did a great job. They not only left the areas clean they hauled off all the old equipment. We would highly recommended them to everyone.

My unit for upstairs had a major leak in the evaporation coils. Jonathan and Matthew came over and spent an hour here investigating and giving me my options. I decided to replace the whole unit and they were here on a Saturday replacing the unit. The knowledge that Jonathan possessed was second to none. The experience was excellent I will be using them again and I highly recommend them.

They were great. Came out on a Thursday and looked at my system. Went over all of my options of repairs or replacements. Explained both the advantages and disadvantages of both options in detail so I could make an informed decision. Came back out the following Monday to do the work. Very friendly and knowledgeable staff.

Jon showed up as planned and committed to. A big plus was that he had the components on his truck to fix the broken part. Had my heat running after a 1 hour service call. Yes, I would recommend Paradise Heating and Air ...5 Star rec.

We have had Jonathan and his capable team working on our A/c and Heating for several years. They are punctual, well mannered and reasonably priced. The work they have done including an A/C replacement has always been outstanding. Plus, we have appreciated their problem solving skills in helping our remaining old units get along from year to year. We are so grateful to have them a phone call away!

Paradise has become our go-to HVAC company. We have used them for several smaller repairs and they always provides a reasonable price and didn’t try to upsell replacing our 30 year old unit before we were ready. Then, when we were finally ready to replace our unit we got quotes from Paradise and several other companies. Paradise was by far the best value not only in terms of price but also unit brand and warranty. We even ran all of the quotes through AI and his came in 1st in terms of value, price and ROI! Great company overall - can always trust them to provide great, high quality work and reasonable prices.

Jonathan and his crew are always quick to respond and on time. They always help me to understand what is going on with our AC and heating units. I get a concise explanation of what needs to be done. I have always gotten an honest answer about my current units and I have never gotten any pressure to replace the equipment that did not need replacing. It feels great to be able to trust the information you get from the people looking after your HVAC equipment, and that is what we get from Paradise. T. Marvin

First of all they are very courteous people. Secondly they gave me an appointment asap and was there right on time in which I was able to keep track of the arrival by text messages. They diagnosed the problem and it was resolved in less than 30mins. I am truly grateful for Paradise Heating and Air. Thank you for your service. Side note: they chose the best name for the company.

I had paradise come out to get me started with their paradise maintenance package, and had them take a look at my attic because we had concerns with our insulation not being adequate. They didn’t try to over sell work I didn’t need, and were honest with what exactly was needed to get us back on track. Techs Jonathan and Matthew came out for the initial inspection and service and came back to do the attic insulation. They were patient and knowledgeable (I ask a lot of questions) and took their time. They found all the places that my system was leaking (out and in) air, fixed them, and then filled the attic. They kept the house clean and were respectful and had great attitudes the entire time. They have definitely earned my business, and I would recommend them to anyone looking for HVAC work. They are AWESOME!
